Mariah Copeland is a fictional character on The Young and the Restless, portrayed by Camryn Grimes and an unknown actress. Grimes also portrayed Cassie Newman and played her "ghost" off and on throughout the years, but in 2014, Mariah is revealed to be Cassie's identical twin. She first appeared onscreen posing as Cassie's "ghost" and wasn't revealed as Mariah for a few months. As Mariah, she was mostly distinguished by a sun tattoo on her wrist, which was hidden by long sleeves when she pretended to be Cassie.
Nurse Helen Copeland was a member of the Path, led by Ian Ward. Helen delivered Sharon Collins' twin daughters, and stole one of them on Ian's orders. The baby was named Mariah, and Helen raised her as her daughter, while Ian served as more of a father figure to Mariah then an actual father. Helen would often abandon Mariah and leave her in Ian's care. Mariah grew up to resent Helen and adored Ian like a father.
Eventually, Mariah left The Path and became engaged to Tyler Michaelson. While Tyler and Mariah were living in Portland, Mariah stole from Tyler's wealthy boss, who blamed Tyler. Mariah slept with the man so that he wouldn't press charges. Hurt by Mariah's betrayal, Tyler ended their engagement and left her.
Working for Victor
Mariah first came into the picture when she snuck into Tyler and Abby's hotel room and made Abby think Tyler was cheating her. She terrorized Abby some more, unnerving her and creating a rift between Abby and Tyler. Tyler went to talk to Mariah and it remains unknown what he said to her, but whatever it was, Tyler and Abby stayed together.
Mariah also encountered Victor Newman who was stunned by Mariah's resemblance to Cassie. Victor, who didn't want Sharon and his son Nick to get back together, hatched a plan to drive Sharon crazy by having Mariah pretend to be Cassie.
"Cassie" then showed up at Sharon's house, trying hard not to be seen. Sharon talked about a secret, which "Cassie" reported to Victor. Victor ordered her to find out what Sharon was hiding.
"Cassie" kept pushing Sharon to tell her the secret, but eventually she grabbed "Cassie" and was horrified to find out she could touch her. Soon, Sharon started believing that Cassie was alive and she was hospitalized and given shock treatment. Victor ordered Mariah to leave town, but she felt bad for the pain she caused Sharon and stayed. Mariah visited Sharon in the hospital and apologized to her.
Nick eventually encountered Mariah and got her to admit Victor was behind her gas lighting Sharon. As proof, Nick brought Mariah to the house to show Sharon she wasn't crazy. After cutting Victor out of his life and ordering him to leave, Nick told Mariah Sharon was going to press charges, but Sharon shocked Nick and Mariah by saying she couldn't hate someone who looked like Cassie.
Victor showed up at Mariah's hotel room and threatened her into staying away from Nick. Scared, Mariah called Ian and was shocked to learn that he was in Genoa City as well. After her talk with Ian, Mariah exited the room and ran into Tyler.
Mariah and Tyler argued about Abby, and Mariah followed him and tried to win him back. Mariah left the room after secretly slipping her bracelet under Abby's bed. Abby ran into Mariah and was horrified when she saw that she was the Cassie look-alike that had terrorized Sharon. Tyler was dismayed that Mariah would do something like that.
As Mariah stayed in Genoa City, she would frequently talk with Sharon, and she was shocked and puzzled by Sharon's kindness towards her after what she put her through.
When someone stole Mariah's money, she called Ian for help, but he couldn't help her, so she reluctantly went to Sharon and ask. Sharon was hesitant but eventually decide to help Mariah. When Mariah returned to her apartment, she found police at her door, who arrested her and she was extradited back to Portland.
In Sharon's debt
Mariah texted Tyler and he went to see her in Portland. When Tyler got back, he told Sharon that Mariah had asked for her. Sharon left for Portland and got the charges against Mariah dropped. Mariah promised to get a job to pay Sharon back and apologized to Abby and Tyler for trying to break them up.
Nick hired Mariah to work at the the Underground, so she could pay Sharon back. Mariah accepted the job, anxious to have a chance to prove herself. Ian encouraged Mariah to pursue a relationship with Sharon, but Mariah almost gave up when Abby framed her for taking Noah Newman's wallet. Mariah was angry with Nick and Noah for automatically accusing her and quit her job. Nick approached Mariah and offered her her job back with some conditions attached. One of them being that Mariah will leave town when she has paid Sharon back.
After Nick saw Ian leave Mariah's hotel room, he confronted Mariah about her connection to Ian Ward. Mariah explained that Ian had been like a father to her, and was horrified when Nick told her he took advantage of young girls. Mariah defended Ian, but later confronted Ian about what Nick had said. When Ian broke into Mariah's room, he expressed concern for her safety, and he persuaded her to move in with Sharon and Nick.
Bonding with Nick and Sharon
After Mariah went to pay Sharon some of her debt, Sharon invited Mariah to stay for dinner. Faith Newman, Nick and Sharon's daughter, took a liking to Mariah. Ian encouraged Mariah to move in with Sharon and Nick. Mariah told Sharon and Nick that someone had broken into her room and that she didn't feel safe. Mariah vowed that Ian was out of her life, and Nick and Sharon agreed to let her stay with them.
Mariah slowly started to develop a crush on Nick and subtly tried to seduce him, despite her similarity to Cassie Newman. As her crush on Nick grew, she stopped defending Ian, and was even willing to side with Nick against him. Mariah was surprised when she received a call from her mother, and Nick was angry because Mariah had told Sharon that her mother was dead. Mariah was desperate to get back on Nick's good side and told him what she knew about Helen. Mariah also met Kevin Fisher and they bonded over their messed up lives and love of a book series.
Sharon finally realized that Mariah was trying to seduce Nick when she saw Mariah come downstairs in lingerie. Mariah tried to tell Sharon she met a guy at work, but Sharon saw through her lie. Mariah and Sharon got into a huge argument and she threw Mariah out of her house. Mariah left the outfits that Sharon bought her. Mariah encountered Kevin, who said he was leaving town and offered a ride. Mariah agreed, but told Kevin they would go their separate ways once they were out of town.
Meanwhile, Nick had started investigating the night Sharon had birth and discovered that Mariah is actually the twin of Cassie Newman, and Sharon's biological daughter. Helen Copeland was the nurse who didn't even want kids. But she stole Mariah for somebody who couldn't have kids, Ian Ward.
Meanwhile, Mariah had ended up leaving town with Ian and he convinced her to leave town with him. Ian took Mariah to a storage unit and drugged her, causing her to lose consciousness. When Mariah awoke, she was wearing a wedding dress and Ian told her that they would get married. Mariah refused to marry Ian, but he didn't listen and got Mariah so drugged that she couldn't coherently say no. They ended up married.
Learning Sharon is her mother and friendship with Kevin
Mariah was rescued by Nick and Sharon and taken to the hospital. At the hospital, Sharon told Mariah that she was Mariah's mother. Mariah refused to believe it and didn't want to embrace Sharon as her mother. Nick convinced her not to leave town, but Mariah refused to come back to the ranch, and she quit her job at the Underground, but Nick convinced her to return to the Underground so she can pay Sharon back.
Noah tried to convince Mariah to give their mom a second chance. Abby came in and started insulting Mariah, so Mariah threw a pitcher of water at Abby, drenching her. Noah snapped at Mariah and told her she was on her own. Mariah and Kevin also started to become closer as friends. She was charmed by Kevin's geekiness and touched that he cared about her.
Mariah heard Sharon murmuring in her sleep about somebody not being somebody else's father. The real story was that Summer is Nick's daughter, not Jack's. Sharon switched the paternity tests so Nick would stay with her. Summer's mother, Phyllis Summers, overheard Sharon confessing this at Cassie's grave when Sharon got into an altercation with her and accidentally pushed Phyllis down the stairs into a coma.
But Mariah jumped to the conclusion that Faith was the child whose paternity had been falsified. Victor paid Mariah to tell him about Sharon's secret. Mariah told him her misunderstanding about Faith. Victor brought a bottle of champagne to celebrate their new engagement, although Victor hates Sharon but has also married her. While Nick and Sharon briefly left, Victor stole Nick's drinking glass and Faith's hairbrush and left for Sweden to get DNA results.
Sharon asked Mariah to be one of her bridesmaids along with Summer and Faith. Mariah was stubborn and reluctant but Sharon kept pushing it so Mariah agreed. Mariah asked Kevin to be her plus one and Kevin agreed. Mariah, Summer, and Faith all had matching dresses for the wedding. Sharon bought Mariah an expensive bracelet but Mariah couldn't accept it.
Mariah attended Sharon's bachelorette party along with Abby, Summer, Lily, Kelly, Victoria, and Nikki which Sharon quickly decided to go to Crimson Lights instead. Mariah was very unenthusiastic and flirted with Tyler who was sitting at the bar just to make Abby jealous. Mariah had Summer give her money to bribe the bartender into stripping. All the girls have been heavily drinking and partying. The guys ended up showing up at Crimson Lights as well and also heavily loaded. Abby had a couple too many drinks and bashed Sharon for marrying Nick again because Sharon married Adam, Nick, Abby's father Victor, Nick again...etc. Mariah stood up for Sharon against Abby, and Abby stated that Mariah spits venom about Sharon every day. Once Michael Baldwin got slammed to the floor, a drunken fight broke out. Mariah fought with Abby. Everybody there ended up in jail. Eventually, they were set free.
The next day, Kevin caught Mariah eyeing a mystery man, Joe Clark. He and Mariah talked about their "not date", and Kevin teased Mariah about liking him. Mariah showed up for Faith's birthday although a little late. She bought Faith her favorite cupcake. Before Nick and Sharon's wedding, Mariah called Victor to get him to rush over there to blurt out Sharon's secret. He said he couldn't and she said then she will. She met up with Kevin. Kevin said she looks pretty and she didn't think the dress was hot enough and ripped off the ribbon around the neck. Mariah claimed she forgot to get Sharon something blue but Sharon didn't mind. When Faith and Summer left for a minute, Mariah gave Sharon a blue bracelet which Faith and Summer came back and saw.
As the wedding progressed, Phyllis Summers made a shocking appearance and then collapsed. The wedding was put on hold and Mariah did her best to comfort Faith. She later confronted Sharon about Phyllis knowing her secret and said she will be there for Faith when "all of this hits the fan".
Mariah eavesdropped on Sharon and Nick as they discussed her fear of the mysterious secret. After Sharon left, Mariah confronted Nick about how he is worried Sharon's secret could affect him. Nick blasted Mariah for not caring about the only person who has shown her compassion. Mariah and Nick talked about Sharon's worries and what would help her. After Nick left the room, Mariah thought about when Sharon first said she was her mother, how Nick told her she has a real family now, and her giving Sharon her blue anklet for the wedding. Mariah was interrupted when Victor phoned her. He told her if the information he gives her pans out, he would pay her. After Mariah hung up, Nick asked who she was talking to and Mariah lied and said it was a political.
Supporting Sharon and Kevin
Mariah took Faith trick or treating on Halloween and told Victor to just leave Nick and Sharon alone and let them get married. Victor warned Mariah she was making a mistake siding with Sharon. Mariah was roped in by Nick, Noah, Sharon, and Faith into taking some photos with the family. Sharon and Mariah had a heart to heart and Mariah tearfully admitted that she stayed in town because Sharon took a chance on her even before she found out they were related. She said Sharon took care of her kids and it was the first time she saw motherly love that wasn't twisted. Mariah said she was on Sharon's side, and Sharon embraced Mariah, saying that Mariah was a part of their family now and that she was on Mariah's side as well. Nick added that they were all on Mariah's side.
Sharon's world fell apart when it was discovered that she had tampered with Summer's paternity test and that Nick was Summer's biological father the whole time. Sharon expected Mariah to turn on her, but Mariah decided to support Sharon because of the kindness Sharon has shown her. Mariah and Noah both spent Thanksgiving with Sharon, and Mariah was shocked when she learned Nick was fighting Sharon for full custody of Faith.
After Kevin snapped at Mariah while she was going on about her day, Mariah decided she needed to learn to be a better friend to Kevin. She also fought with Summer over her and Nick's willingness to use Faith to punish Sharon. When Mariah overheard Summer and Abby talk about Kyle Abbott, who Summer had dated before she thought she was Kyle's half-sister, Mariah planted a seed of doubt in Austin's head about his and Summer's marriage. Kevin persuaded Mariah to leave Summer and Austin alone. Mariah came home and found that Sharon didn't want to go to work because of people judging her. She convinced Sharon to prove she could provide a stable home for Faith. After Sharon left, Mariah and Noah talked about how they would need to help Faith through the custody fight.
Mariah was taken aback when Kevin said that his brother, Michael Baldwin, had cancer, and simply said "that sucks". Kevin lashed out at Mariah for her lack of understanding and accused her of not caring. Mariah told Kevin she understands he is upset, but she is not his "whipping boy". Kevin decided he shouldn't have told Mariah and went to leave. Mariah caught up with Kevin and apologized to him. She told Kevin that she was there for him, and hugged him. Kevin then kissed Mariah. Mariah was stunned by the kiss and the two debated what to do from there. Kevin decided he didn't want to jeopardize there friendship when Mariah suggested they have sex, and agreed to help her decorate a Christmas tree he had bought for her.
While they were decorating, Kevin hung mistletoe over his and Mariah's head and teased her about being afraid to kiss him. As Kevin and Mariah went to kiss, Sharon came home and Kevin left soon after. Sharon tried to get Mariah to open up about Kevin, but she was hesitant to. Sharon told Mariah that she would never fall in love with someone if she closed herself off to the idea. Mariah admitted she isn't sure if she knows what love is, and Sharon assures her she will one day know when she falls in love with someone.
First Christmas and the New Year
Mariah spent her first Christmas with her family. On Christmas Eve, Kevin asked for Mariah's help in searching for Detective Mark Harding's rabbit, Roscoe. Mariah found Roscoe, and discovered that Roscoe was a she and had babies. Kevin and Mariah wished each other a Merry Christmas and went back to their families. Mariah showed Faith a photo of the baby bunnies she had taken with her phone. Kevin and Mariah kissed again on New Years Eve, but this time it was Mariah who initiated the kiss.
Birthday Blues and Kissing Austin
Mariah and Noah got closer as they mutually supported Sharon. After Sharon left for mediation, Mariah and Noah playfully teased each other about being Sharon's favorite kid. Soon, Summer, Austin, and Courtney joined them. Mariah was stunned when she learned Kevin had a criminal past. She goes to the police station to talk to Kevin and found a dagger in a box on Kevin's desk. Mariah freaked and jumped to conclusions that Kevin had the dagger because he was in trouble, but she soon realized that it was memorabilia of their favorite book series. Mariah told Kevin that he can come to her if he is ever in trouble. Kevin teased Mariah about being turned on by his dark side, but she says she was just worried about him. Kevin quips that is even better, and they laugh and say how they will continue to make fun of each other
On Mariah's birthday, she seemed unusually grouchy with both Austin and Kevin. Mariah left work early to visit Cassie's grave and wish her deceased twin a Happy Birthday. Nick shows up to put flowers on Cassie's grave and they talked about Cassie. Nick gave Mariah a ride home where Sharon, Noah, and Faith were waiting to celebrate her birthday and they were convinced to stay for some of Cassie's favorite cookies. Kevin showed up to wish Mariah a happy birthday, and Mariah invited him in. Kevin informed them about Victor being involved with the warehouse district. Sharon gave Mariah a present which was a garnet necklace which was the birthstone of both Cassie and Mariah. Mariah didn't want Cassie's leftovers, got grouchy and left. Kevin followed her and gave her a birthday present. It was a portrait of a FanFiction character which Mariah loved. Mariah went to The Underground and kissed Austin after he wished her a happy birthday.
Kevin showed up and was surprised to see Mariah kissing Austin. Mariah said she liked kissing Austin and Summer came back and asked what Mariah liked doing. Kevin covered for Mariah and she left soon after. Kevin followed Mariah to Crimson Lights where they argued. Mariah accused Kevin of being jealous, and told him to go so they can stop being friends. Mariah said she was sick of being picked apart and analyzed by everyone. Kevin said he isn't trying to run her life and that he honestly cares about her. He tells her he knows what it's like to protect yourself from the world. Mariah admits she can't handle people caring about her. Kevin tells Mariah she deserves to be loved, and Mariah admits she is afraid of something real. Kevin tells her she may find someone someday and then leaves.
Mariah apologizes to Austin for kissing him. Austin tells her he understands why she did it, but that what she did was selfish. Austin also tells Mariah she could end up hurting Kevin as Kevin walks in. Austin makes himself scarce, and Kevin talks with Mariah about the conversation they had. Mariah asks Kevin why he cares so much, and Kevin says he figures maybe he can help himself by helping her. He asks for a donation for the cancer run he and Michael are doing. Mariah decides to give Kevin all of her tips. After Kevin leaves, Austin returns and Mariah says she and Kevin are just friends. Austin tells her that it doesn't mean that she and Kevin can't be more than friends. Summer comes in, and Mariah tries to apologize, but Summer rants at how Mariah is pathetic and selfish and how no one could ever love her. Mariah leaves upset and heads to Crimson Lights. Kevin sees her and they embrace.
After a donut and a coffee, Mariah was ready to head home. She asked Kevin to give her ride. They arrived at Sharon's house just as she was leaving to meet with her attorney. Faith told Mariah that she told Sharon a lie about Nick asking a woman (Sage Warner) to take off her clothes when what had really happened was that Sage had spilled water on herself. Mariah reassured Faith that she wouldn't be in trouble. Kevin realized Mariah was considering not telling Sharon what Faith told her, so it could give her an advantage against Nick. Kevin convinced Mariah that was the wrong thing to do. Nick and Noah came back home, and Kevin left. Nick asked Mariah where Sharon was, and Mariah said she was with her lawyer. Sharon came home and asked Noah and Mariah to put Faith to bed while she talked with Nick.
Fallout with Sharon, party, and murder
Mariah was called to testify at the custody hearing, and Avery asked her to tell the truth about what Faith told her regarding Sage and Nick. Mariah was reluctant, but Avery pressed her and eventually Mariah admitted that what happened between Nick and Sage was harmless. This caused Sharon to get upset and she had to leave the courtroom to calm down. The judge ultimately granted Nick sole custody. Sharon would have visitations at Nick's discretion until the case was revisited in a year.
Dylan comforted Sharon and asked if he could do anything for her. Sharon asked him to get her out of the courthouse. Mariah volunteered to give Sharon a ride, but Sharon told her to stay away from her and said that Cassie wouldn't have stabbed her in the back. Mariah cries that she didn't stab Sharon in the back and had to tell the truth since she was under oath. Sharon lays a guilt trip on Mariah about all she has done for her and asks why she couldn't just back up Faith's initial claim. Mariah says she doesn't owe Sharon anything. Sharon tells her she lives in her home, and Mariah says that she will move out; if Sharon doesn't want her than she doesn't want Sharon. Sharon said that was fine with her before leaving with Dylan. Kevin showed up and Mariah told him she feels like she failed as a daughter and Sharon doesn't love her as much as she loved Cassie. Mariah laments that she doesn't have a place to stay and Kevin says she can move in with him.
Despite her argument with Sharon, Mariah still defended her to Summer, and she ultimately accepted Kevin's invite to move in with him as a friend. Mariah received a mysterious Valentine's invite to a party at the Abbott cabin, and wondered who sent it. Austin came in and Mariah and Kevin asked them about the invites. Austin said they got the same one, and Summer seemed surprised. Mariah realized Summer and Austin were having problems and gleefully wanted to talk about it some more; Kevin suggested that they don't. As the four of them wondered who sent the invite, someone watched them from behind a curtain at the Underground.
At the cabin, Mariah, Kevin, Austin, and Summer were joined by Abby, Fenmore Baldwin (Kevin's nephew), and Noah. Noah called Abby out on being the one who called them to the cabin, and she admitted it. Abby suggested they play Never have I ever. Everyone grabs a cup and Kevin stops Fen and gives him a stern look. Mariah asks if Kevin really thinks Fen doesn't drink in school. Fen says that everyone does. Kevin says he hopes Fen is doing it responsibly, and Mariah laughs. Summer said "Never have I ever had a crush on a best friend", which Kevin and Mariah looked at each other and drank. The game started as casual fun until Fen said "Never have I ever committed murder," which causes Austin to storm out in anger.
Austin comes back and apologizes for storming off like he did, saying that talking about murder made him think of his mom. Abby wants to continue the game, but Summer and Austin decide to leave. Courtney shows up and says that everyone has to stay there because there is a bad storm out there. Someone spikes the punch, and everyone loses consciousness after drinking it. When they regain consciousness, they can't find Austin. Kevin goes out to look for him, but comes back when he can't find him. Kevin opens the closet doors and Austin tumbles out.
Courtney tries to revive Austin, but pronounces him dead. Courtney finds blood by Austin's head and tells everyone not to touch the body. Everyone gets scared and starts accusing each other. Noah finds a vial in the garbage, and Fen admits he spiked the punch with a drug that was supposed to loosen everyone up, but he admitted he didn't know what it was and wouldn't say where he was. Abby starts yelling at Fen, and Kevin defends him by bringing up the "Naked Heiress" stunt from Abby's past. Abby defends that it was a publicity stunt and that know one ended up dead. Mariah says that Abby cannot talk about Austin that way. Summer yells at Mariah to not talk about Austin at all, and Mariah screams at Summer that she was looking out for her feelings.
Suddenly, Mariah remembers this is like a part from one of Plato Sphere's books. Kevin gets defensive when people start attacking Plato Sphere, and he admits he is Plato Sphere. Mariah and Fen defend Kevin, but everyone else accuses him of murder. Summer remembers hiding a bloodied bookend under one of the couch cushions. She finds it and screams in horror. Summer tearfully starts crying that she killed Austin, but Noah and Fen refuse to believe it. Courtney bags the bookend for evidence. Summer starts hyperventilating and Abby, Noah, and Fen try to calm her down. Courtney says Summer couldn't have gotten Austin into the closet, so Kevin implies that someone may have helped her. Fen snaps at his uncle, and Mariah tells Fen not to get mad at Kevin when this is his fault for drugging them.
Abby takes Summer out of the room to calm her down, and Kevin scolds Fen for using drugs again. Courtney says she has to report everything that she hears, but Kevin and Noah say they won't testify about what Summer said. Courtney tells them to stop it, and says that even though Summer's confession was made under duress; she still has to report it. Kevin and Mariah make up a story about Austin slipping and hitting his head. Courtney is dismayed that they want to cover up Austin's death. Mariah says Summer doesn't deserve to go to jail. Courtney is adamant that they be honest, so Mariah asks Courtney if she wants to tell the police that there was a homicide, and know one remembers what happened because Fen drugged them. Summer finds the murder weapon, says she did it, and gets arrested. Mariah asks Courtney how that version works out for her. Courtney says what they are doing is a felony, and asks Noah to back her up; but Noah sides with Mariah, Kevin, and Fen. Courtney says they could get caught and then all of them would go to prison. Kevin suggests that she use her expertise to cover it up. Noah, Kevin, Mariah, and Fen all agree to the cover up, but Courtney says they are making a mistake. Noah apologizes to Courtney, and she cries that if she does this then she is no better than the dirty cops that think they are above the law. Noah says he is asking Courtney to save his sister because she can't save herself, so Courtney reluctantly agrees to help them.
Kevin and Noah lift Austin's body, so there is no evidence. Courtney says they have to make sure the angle of the blow makes sense, and says they are going to do this right. Mariah asks Abby to take care of Summer. Kevin and Noah lay Austin on his side, with his injury laying on a rock, so it looks like he slipped and hit his head on the rock. After everyone goes back inside, Mariah tells Austin that Summer loves him, and they will keep her safe for him. When Mariah heads inside, she has a flashback of seeing Abby and Austin kissing. In private, Mariah confronts Abby about what she saw and deduces that Abby and Austin were having an affair behind Summer's back. Abby denied it, but then came clean about it after Mariah said she will ask if anyone else remembers what she saw. Abby tells her the truth and Mariah is shocked that Abby could do that to Summer behind her back. Abby lays a guilt trip on Mariah about the things she did to her and Sharon. Abby tells Mariah if she says anything, she hands the police the perfect motive: Summer killed Austin because she was cheating on him; Mariah says it is the perfect motive for Abby because he wouldn't leave Summer. Courtney gets a text saying the roads are clear and the police would be on there way. She asks everyone more time if they are going through with the cover up. Noah says that he would tell the police that he was helping Austin with a ladder to clear snow off the roof, and that's how one else was out there; and that he didn't even see him fall. Fen goes to set up the cover up. He comes back and announced that Austin's body is gone.
Summer is hopeful that Austin may still be alive. Noah goes to look for Austin, and the police arrive and ask what happened. Kevin covers and says he fell off the ladder, but he is fine. They say Austin went to look for help and never came back. The group is taken back to Genoa City where they give statements. Noah leaves after hearing about a collapse at the Underground. Mariah and Fen sit with Summer in the interrogation room. Summer is panicking and Mariah tells Fen to get Summer under control because she isn't going down for something she didn't do. Summer continues to freak out, and Mariah loses her patience with Summer. She tells Summer that this isn't just about her anymore, and that they are all in trouble if the truth comes out. Summer shoots back that this was Mariah's idea, and that she didn't ask her to do this. Mariah scoffs that she did this for Austin, and not for Summer. Paul comes in and announces that Austin has been located and that he is fine.
Kyle Abbott returns
Paul takes Mariah, Kevin, and Summer out by where the Abbott Cabin is. They see someone, wrapped in a blanket coming towards them. Summer runs to the figure only to discover that it is Kyle Abbott. Paul asks Kyle what he is doing out there, and Kyle says that his car stalled. Mariah and Kevin immediately wonder if Kyle had been the one who moved Austin's body, and even wonder if he had been the one who murdered Austin. Summer is appalled at the idea, but Mariah and Kevin want to investigate Kyle's car. They find a piece of fabric sticking out from the trunk. Mariah and Kevin want to open the trunk, but Summer is against the idea. Noah arrives, and agrees with Mariah and Kevin on opening the trunk. Mariah procures Kyle's keys and unlocks the trunk.
In Kyle's trunk, they find a flashlight and first aid kit. Mariah admits she expected to find Austin's body instead, and Summer goes off on Mariah for thinking the worst of Kyle. Mariah tries to explain what she meant, but Summer carries on, and Mariah angrily tells Summer that they are on the same side. Kevin finds a bloody cloth in the trunk, and Noah suggests they have Courtney look at it. Mariah doesn't trust Courtney, and is worried she would sell them out. They head to the hospital to confront Kyle about what they found. Abby wonders why Kyle would cover this up, and Mariah says there is no telling what someone would do to protect the person they love. Kyle comes into the room, and Noah says he remembers seeing Kyle outside of the Abbott cabin, and Kyle denies that he was there. Kevin asks about the bloody cloth, and Kyle says he had a boxing match before he came home. Kyle asks why does he feel like he is being accused of something, and then asks what really happened to Austin.
Abby thinks they should tell Kyle, but Mariah says that too many people already know. An officer comes by to talk to Summer, and while that is happening out of the room, the group tells Kyle how they think Summer killed Austin, and they staged it to look like an accident. Summer comes back and says that Austin's body was found in a wrecked car. Abby wonders if Austin could have survived, and died by crashing an abandoned car; but Mariah brings up that Austin had no pulse. Summer is asked to identify the body, and the group stays in the waiting room. After Summer identifies Austin's body, she heads to the chapel to mourn him. As the group wonders if Austin had anyone else who cared about him, Mariah realizes Abby had real feelings for Austin. After Kyle leaves to check on Summer, Mariah says that she doesn't trust Kyle, and Abby says that's because she doesn't know him; Mariah adds that she doesn't trust Abby either. Noah asks Kevin if he can discreetly get the blood on the rag analyzed, and Kevin says that he can.
Kevin, Mariah, and Noah share their suspicions about Kyle with Abby. Abby can't believe Kyle would be an accomplice to murder, but Noah says he is hiding something. The four head over to Summer's place where she is watching a video Austin made. After Summer left the room in the video, Austin turned to the camera and said he owes Summer an apology. Austin went on to say how he was depressed, and how he needed to tell Summer something. Summer had interrupted him before he could make his confession. Kevin noticed the way Mariah stared at Abby and took her aside to ask what was going on. Mariah avoided answering Kevin, but he asked her again when everyone had left the room. Mariah told Kevin that she doesn't think Austin was depressed in that video, and that he was instead guilty. Kevin asked about what, but before Mariah could tell him, the video switched to Austin and Abby joking around at Crimson Lights. Summer came back and was wondering why Austin had a video of Abby on his laptop. Noah said Austin was working on a documentary about corporate titans. Summer said she doesn't remember, which made her feel even worse. Kevin got a text from his contact, who got the blood on the towel analyzed. Kevin and Mariah went to the station where they learned that Kyle lied when he said the blood on the towel was his; it was Austin's blood.
Courtney comes into the room and Mariah and Kevin tell her the blood on Kyle's towel is Austin's. Kevin shares his theory that Kyle killed Austin, and Courtney says that Kyle could have put Austin's body in the armoire, but wonders why Kyle wouldn't just leave with Austin's body. Kevin says maybe he wanted them to find the body. They decide to leave for Austin's memorial, but Mariah stays behind. Kevin listens as Mariah talks about her friendship with Austin and how she misses him. Mariah leaves without Kevin, who gets held up. At the memorial, Mariah talks about how she and Austin had a lot in common. She says he was a good friend and co-worker, and that she misses him. Summer gets up, and talks about Austin, and how her family welcomed him. She then stops and suddenly accuses Abby of sleeping with Austin.
The anonymous messages
Abby runs out of the church in tears, and Mariah accuses Kyle of knowing about the affair. Summer asks Kyle if he knew, and he reluctantly admits he did. Summer asks who else knew, and guesses that Mariah knew because of her and Abby's private talk at the cabin, and that Kevin knew as well. Summer continues to have a meltdown, and Jack and Phyllis order everyone out of the church. Outside, Mariah, Kevin, and Courtney continue to accuse Kyle of Austin's murder. Kyle snaps that they don't even know who they are protecting, and that they could be protecting themselves.
Mariah, Kevin, Kyle, and Courtney storm into the Abbot cabin and accuse Abby of Austin's murder. Abby says she didn't do it, and says that they all have as much motive as she did. Abby says Mariah could of been jealous that Austin chose to cheat with her instead of Mariah. She turns to Kyle and says he could have done it because he wants Summer for himself, or that Kevin could killed Austin because he was jealous of Mariah and Austin's friendship. Abby opens the armoire and the group sees that a message reading "I know what happened here" is written on the mirror. They wonder who could have wrote it, and Courtney takes a picture of it. Summer and Noah go to the Abbott Cabin where Kyle, Mariah, Kevin, and Courtney are. Courtney tells Summer that she didn't kill Austin, and Kevin and Noah say the blood on the towel was Austin's. Kyle explains that he punched Austin, but Mariah and Noah are still skeptic because he lied about the blood being Austin's and also lied about being in town. Kyle's explains that he wanted solid proof before he told Summer about the affair. Abby comes out of the back room, and Summer charges at Abby. Noah holds her back, and Abby runs out of the cabin. Kevin and Courtney show up for work and tell Noah and Mariah they might as well leave since they aren't getting anywhere. Noah wonders what they should do. Mariah figures the person who wrote the note must have known they wouldn't tell anyone. Noah figures that means the person knows them pretty well, and Kevin wonders how well they know this person.
Mariah returns to the Abbott Cabin to get her scarf and sees Abby there. She taunts Abby about her affair with Austin, and Abby says she feels bad and tried to apologize to Summer. Mariah asks how it went, and Abby admits that Summer slapped her. They both get a text from Summer, asking them to meet at the Abbott Cabin. Once everyone involved is at the cabin, Summer shows them the message on her mirror, saying "I know what you did". Mariah and Summer both continue to accuse Abby of lying, and she leaves in frustration. Kyle goes after Abby, and the group continues to wonder who is watching them, and leaving the messages. Noah thinks it is convenient that Fen left town shortly after Austin's death. Kevin says he has school, and is trying to get his life back in order. Mariah asks if drugging them was part of his rehab program. Summer says she knows, and Fen he wouldn't do it. Mariah says she also thought she knew Austin, and is a bad judge of character when it comes to men. Summer and Mariah start fighting about Austin, and accusing each other of writing the messages. It escalates, and Kevin and Noah have to pull them apart. Courtney says they should go to the police, but Mariah, Kevin, and Noah are against the idea. Mariah says she isn't going to jail to protect Summer, and Summer says that she never asked for her help. Mariah snaps that she would turn her in if she could, and Kevin tells them to shut up. Kevin shares his theory that someone has been planning this set up for a long time, and Summer wonders who would want to kill Austin. Suddenly, the group hears a noise and rushes out to hear the sound of someone running away. Summer feels they should go to the police, and Mariah says she is the reason she they didn't to to the police. Summer says she doesn't think she killed Austin anymore, and tells them what she remembered. Despite Kevin and Mariah's objections, the others leave to go and tell the police while Mariah and Kevin stay behind.
Kevin decrypts a file on Austin's computer, where he spoke with such hatred about the Newman and Abbott families and promised to reveal all about them. The group figures that someone from the Newman or Abbott families could have had Austin killed. Kyle says Jack isn't a murderer, and Summer says Victor wouldn't do something so horrible, and they don't know him. Mariah points out that Victor hired her to gaslight a mentally ill woman (Sharon), so she knows him pretty well. Mariah continues to taunt Summer about how she didn't really know Austin, and Summer says Mariah will never know the kind of love she and Austin had. They soon find out from Stitch that Abby had told him all the details of Austin's death. Kevin questions Stitch, and he is offended by the idea that they think he had something to do with Austin's death. Stitch says he didn't really know Austin other than when Austin asked to interview him, and Stitch said no. Kevin later finds out that was a lie, and finds a file of Austin trying to interview Stitch.
Mariah and Kevin are at Sharon's looking for her phone charger. Mariah continues to insult Abby, and Kevin asks if she still hates Abby because she blames her for stealing Tyler from her. Mariah isn't sure, but admits that she is jealous because Abby is rich, smart, funny, fearless. Kevin tells Mariah says is all of those; except rich, and tells Mariah that Abby has nothing on her. Mariah disagrees and thinks guys go for the rich, good-looking girls. Kevin says Mariah has substance and cares about others. He tells her that even though she won't admit it, he knows she is just trying to protect Summer. Kevin tells Mariah without her he would be out of his mind. Mariah laments that hanging out with her hasn't stopped Kevin from breaking the law and Kevin says there is no one else he would rather face jail time with. Kevin suggests getting a phone charger, that was confiscated, at the station. Mariah jokes that they get away with covering a murder, but get caught taking a phone charger. Kevin says Platro Sphere outsmarts the good and the bad guys. Mariah says he almost makes breaking the law sound noble, and says Kevin is a fun person to get in trouble with. They are about to kiss when Sharon comes home. She is surprised to see Mariah there, and says she hasn't seen her much since the trial. Mariah reminds Sharon that she kicked her our, and notices something is off with Sharon. Kevin make himself scarce, and Mariah says she misses talking with Sharon. Sharon apologizes to Mariah and says she had missed her. Mariah asks Sharon what's wrong, and Sharon proceeds to tell her about how she let Austin interview her and accidentally said some bad stuff about the Newman family. She originally intended to help Austin for Summer's sake, but he pushed until she snapped. Sharon says she was furious with Austin and would have done anything to stop the documentary.
Mariah and Noah are annoyed at Summer's persistence that Sharon is guilty of murdering Austin. Mariah accuses Summer of wanting Sharon to be guilty and says that Sharon could have told Austin something that Victor or Nick didn't want getting out and they could have hired someone to kill Austin. After talking to Dylan, Noah comes back and is even more worried that Sharon is guilty. Mariah says that once they find the interview, they can prove Sharon is innocent, but Noah is worried that it could make Sharon look even more guilty. Noah leaves after getting a call from Dylan about Sharon, and Kevin finally decrypts Sharon's interview. In it, Sharon says that Nick did something so horrible that he would be in prison if Victor hadn't covered up. Summer refuses to believe it and accuses Sharon of lying. Noah comes back and says Sharon got the same lipstick message they did. Summer suggests Sharon wrote it and argues with Noah and Mariah about it. Kyle speaks up and admits he wrote the message on Sharon's mirror. Mariah and Noah are furious with Kyle for playing with Sharon's mind, and he explains he did it to ferret Sharon out and get her to confess. Noah punches Kyle and is restrained by Kevin. Noah insists that Sharon is innocent, but Summer says they found evidence that points to Sharon. Mariah and Kevin add that the evidence could also point to Victor or Nick.
Noah and Courtney got engaged, and planned to get married. Kevin found a video of Jack in Chancellor Park and asked for Courtney's help to back the security footage. They tripped an alarm and alerted Paul. Kevin took the blame and Paul suspended him. On the way to the wedding, Courtney was Kate and texted the group asking them to meet her at the Abbott cabin. When they got to the Abbot cabin, they found Courtney dead in the armoire and a note in her hand saying "I warned you, stop digging". Mariah tearfully called the police as the forum decided they could no longer keep this a secret. They confessed the whole truth about Austin's murder, and Paul was furious with the group and scolded them for keeping it a secret. He allowed Noah to stay with Courtney's body, but took the rest back to the station and took their statements. Kyle accused Sharon of the murder, but Mariah said that she doesn't believe Sharon is capable of murder. She gave Noah a hug, saying she doesn't do sympathy well; Noah understood.
Proving Sharon's innocence
Mariah showed her support for Sharon and told her she believes in her innocence and will prove it. Sharon hugs Mariah, happy to hear she is on her side. Michael learns that there were traces of latex found on the fire iron, and Mariah theorizes that some one could have made latex copies of Sharon's fingerprints and planted them on the tire iron. Kevin reveals that Paul found security footage of Sharon at Summer's apartment the night Austin was killed, but then Kevin realized that the the Deli was open when the photo was taken, but it would have been closed at the time the photo was taken; meaning the time stamp was fake.
Mariah went back to work at the Underground when Nick reopened it. She quarreled with Nick over Sharon's innocence, but then Sharon showed up at the Underground. Mariah and Noah tried to convince Sharon to leave, since the charges hadn't been dropped, but she wouldn't listen. Sharon was arrested and Mariah and Noah went to the station to try and get through to Sharon. Sharon realized she may have forgot to take her meds and Mariah gives her a pill. Mariah tells Kevin that Sharon is her own worst enemy and realizes they are the same. She tells Kevin to run, but Kevin says he isn't going anywhere and they hug. Mariah, Noah, Faith, and Dylan organize a welcome home party for Sharon when she is cleared of the charges. Nick has to work, so Mariah and Noah offer to stay with Faith at the tack house.
Search for the real killer
Mariah and the rest of the group meet to touch base about the killer. Summer, Kyle, and Abby want to believe the killer is no longer interested in them, but Mariah is not convinced. They all get a text to go to the cabin. Noah, and Kyle want to go, and Kevin goes with them when he fails to stop them. Ben shows up, and joins the other guys at the cabin. Summer calls Paul, and then heads to the cabin with Mariah and Abby. They find Fen at the cabin and arrive just as he admits he has been in contact with the killer. Fen explains he was blackmailed into drugging them because he hacked into the school's computers and changed his grade. Mariah and Noah are angry at Fen because he didn't say anything sooner, and let Sharon be arrested for it. Paul bursts in as Noah lunges at Fen. Fen tells Paul everything he knows and gives him the envelope that the drugs came in.
The group learn from Paul that the DNA evidence from the envelope was a match for an anonymous drug lord named Marco Anacelli. As the group wonders why a drug lord would kill Austin, Kevin suggests the FBI may have changed the results. He tried hacking the FBI's database, and Paul scolds them for interfering in the investigation. He then says there isn't enough evidence to prove Marco is the killer. Mariah worries about the consequences for Kevin if he is caught hacking into the FBI database. She tries to talk to him out of it, but Kevin discovers that Tobias Gray, a former employee of Jabot, is a suspect. He and Mariah break into Tobias' apartment and find a flash drive and latex fingerprints. Tobias dies in a car crash, and everyone believes it is finally over, except for Kevin. Mariah is torn between trusting Kevin's instincts and her desire to feel safe. Summer and Kyle are annoyed when Kevin posts on GC Buzz that Tobias isn't the killer, fearing it has put them in danger. As Mariah tries to defend Kevin, she accidentally blurts out that she loves him, and then gets all flustered when she tries to deny that she loves Kevin more than just a friend.
Kevin gets caught and is arrested, but the killer posts a taunting response on GC Buzz, meaning that Kevin was right. Kevin gets the idea of making a documentary where they are interviewed about what they know to put more pressure on the GCPD to catch the killer, but everyone, including Mariah, is against the idea. Mariah then confesses to Kevin that she posed as the killer online and sent the taunting response to Kevin's post, hoping to get him out of trouble. Mariah is worried that if she were to be found out, she could go to prison, and asks Kevin to help her.
Kevin tells her he can't help her because they have already traced her IP address. He advises Mariah to confess, and says Michael can help her, but Mariah tells him they should run. Kevin doesn't think running is a good idea, and Mariah tells him she understands if he doesn't want to leave, and tells him it's been fun. As Mariah goes to leave the Underground, Paul and Harding arrive and bring Mariah and Kevin down to the station. Paul finally reveals his plan to lure the killer into a false sense of security. Kevin tells him he needs to put more pressure on the killer. Harding prepares to arrest Mariah, but Paul calls Harding into his office. Alone, Kevin asks Mariah if she was fine leaving everyone she cared about behind. Mariah says she would have missed Kevin, and Paul comes back in. He tells them they are free to go, but he warns them not to interfere with the investigation again. Kevin and Mariah return back to the Underground and he resumes to ask her if she was really going to leave without thinking about him. Mariah says that she would have missed him and probably would have been miserable thinking that she could never see him again.
Being protective and supportive of Sharon
Mariah was worried when Sharon made a 911 call, and thought someone was stalking her. Sharon assured her that she made the call on Avery's behalf. Mariah openly questioned Dylan's love for Sharon since he also ran off to help Avery. Sharon assured Mariah everything was fine, and said she can't complain since Dylan dropped everything to help her. Mariah later found Dylan about to start a fight with Joe Clark, and told him that it would look bad for her mom if he got thrown in jail. Alone, Mariah warned Dylan not to hurt Sharon.
Mariah was invited to the house, along with Noah, Paul, and Nikki by Sharon, who had some exciting news to share. Mariah assumed that Dylan had proposed, but was stunned when Sharon announced she was pregnant. Mariah, once again, openly doubted Dylan's commitment, as he had rushed off to see Avery. Sharon and Nikki got into an argument, and Sharon ordered Nikki to leave. She also told Mariah to get out if she wasn't going to be supportive, and accused Mariah of trying to get her going. Mariah admitted she did because she doesn't think Dylan is fully committed to her, and she doesn't want him to hurt her. Noah tells Mariah that Sharon needs their full support, and Mariah apologizes. Sharon forgives Mariah, and they embrace.
A new lead on the killer
Mariah has Kevin do a background check on Marisa Sierras, and openly admits she doesn't trust her. She and Kevin find out that Marisa lied about not being romantically involved with Marco. Marisa told them that Marco was at the bottom of the lake. Kevin and Mariah went swimming in the lake and found the car, but no Marco. Kevin and Mariah told this to Marisa and Noah, and tried to get more answers from Marisa, but Noah was adamant that she was trustworthy.
Mariah and Kevin went to the police station and told Harding what they had found out. Harding came with them to the underground and questioned Marisa about Marco. Kevin started to become suspicious of Harding, and keeps an eye on him while Mariah spies on Marisa. Kevin tells Mariah they should go camping to keep track of Harding, but Mariah flat-out rejects the idea. Instead, she convinces Kevin to talk to Paul and let him investigate. Paul told them he will investigate Harding, but then warns Kevin and Mariah to stay out if it. Just as Mariah thinks they can finally relax, Kevin pulls out his laptop to do some more investigating on Harding.
Summer has an encounter with Harding, and hears her ringtone. She remembers hearing it that night at the cabin, and plays it for the group, and asks if they have the ringtone. They answer that they don't, which only makes them more suspicious of Harding. Mariah becomes worried when Kevin won't respond to her texts. Kevin shows and says he followed Harding to the cabin. Later, Summer confirms that she did in fact see Harding at the cabin. Noah rushes off in anger, and Summer is in a frantic state. Mariah offers Summer some water, and tries to help her calm down. Dylan comes by and follows Noah.

Dylan rushes up to confront Harding, who holds him at gunpoint. Paul shows up, and a tense stand off ensures as Harding tries to use Dylan to get Paul to lose his gun. As Paul lowers his gun, Dylan grabs Harding and they struggle. Sharon screams as a shot is fired, and leans on Mariah and Summer for comfort.

On the roof, they stand back as Stitch tries to stop Harding from bleeding out, but Harding dies soon after.

Mariah went to see Sharon, and warned her that Noah and Dylan have realized something is off about her.

Mariah reminds him they aren't normal, and lists all the normal couples that didn't make it. Kevin tells her to forget it.

Sharon started worrying that Nick was figuring things out. Mariah assured Sharon that he wasn't suspicious, but Sharon wasn't convinced. Mariah asked if Sharon wanted to tell Nick the truth. Sharon said she can't, and added that Mariah can't say anything either. Mariah says she won't, since everything will come crashing down around them if she does. Nick thanks Mariah and Sharon for Ben f there for him, and leaves. Sharon worries the more time Nick spends with Sully; the more he is likely figure out the truth. Mariah says seeing Sully helps Nick, and if they take that way from him, then they are truly monsters.
Sharon says she doesn't have a choice and she can't risk losing Sully. Faith comes down and asks Sharon why they were talking about losing Sully. She asks if Sully is sick, and Sharon says Sully is a healthy baby boy. Dylan comes on and asks why she would think otherwise. Faith says she heard Sharon saying she can't lose Sully. Sharon chastises Faith for listening, and says she misunderstood what they were saying. She sends Faith upstairs to get ready, and Mariah goes with her.
After Sharon and Faith leave, Dylan tells Mariah he trusts her to tell him if what's going on with Sharon. Mariah asks Dylan why he thinks something is wrong with her mom. Dylan says he notices Sharon has been anxious lately, and he is not asking Mariah to violate Sharon's trust, but he needs to know what is wrong, so he can help her. Mariah says Sharon is still dealing with Sage's death, and thinking about Cassie. She says Sharon struggles to control her emotions even at the best of times. Dylan says he wants to make her she doesn't have a relapse and end up back in Fairview. Mariah assures him she is making sure Sharon has her meds under control. Mariah tells Dylan that Sharon really loves him and her whole family. Dylan says they are stuck with him and nothing is ever going to change that, before leaving for work.
Sharon thanks Mariah for being a good sister. Mariah angrily asks if she gets a gold star for changing Sully's diaper, and lying to Faith, or a blue did on for lying to Nick and Dylan. Sharon says she knows this isn't easy, but they have to think what is best. Mariah snaps that it isn't best for Sharon to turn herself inside out, juggling all her lies. Mariah warns her that Dylan knows something is up, but she covered for her. Sharon asks if she can count on Mariah in the future. Mariah says she doesn't want to Sharon or Dylan, so she will keep quiet because this is her family too.
Trying to help Sharon
As Sharon became more and more stressed with lying to both Dylan and Nick, Sharon had a nightmare of Sage, demanding to know why she hadn't told Nick that Sully was really Christian. "Sage" accused Sharon of not telling the truth because she was a selfish liar. This convinced Sharon that she couldn't go on living this lie, and had to come clean, even though Mariah reminded her of the consequences she could suffer as a result. Mariah advised Sharon to talk to a shrink, but Sharon said Mariah is the only one she can talk to. Mariah says she is her kid, and not her shrink.
Dylan comes in, and asks what they were talking about. Mariah said they were taking about Sage, and how Sharon is covering both jobs at Chelsea 2.0. Mariah said she was thinking of helping Sharon, and Sharon added she can't talk to anyone, but Mariah because she didn't want to seem insensitive when everyone was mourning Sage. Dylan told them there would never be a right time to talk to Chelsea, and says they have done nothing wrong. After Dylan left, Sharon and Mariah glanced at each other, knowing that wasn't true.
Sharon had another dream about Sage, and Mariah told her she has to talk to a psychiatrist. Sharon said she can't because the psychiatrist would be compelled to tell the police, and she would lose her family. Nick came by, and strayed communicating with Sully. Sharon flashed back to Sage wondering how she couldn't tell Sully was Christian. Mariah took Sully upstairs for her nap. Nick could tell something was wrong with Sharon, and tried to get he to confide in. Mariah came down and told Sharon Sully wanted his "mommy". As Nick went to question Mariah, she said she had somewhere to be, and had to get ready, so Nick left. Sharon thanked Mariah for covering for her, and Mariah said she is acting too suspicious.
Mariah told Sharon to get out of the house and do something. As she escorted Sharon out, Kevin showed up. Sharon left, and Mariah asked Kevin what he was doing at Sharon's house. Kevin says he misses Mariah. Mariah said Kevin moved out because he is a rich jackass now, and asks why he isn't enjoying his millions with Natalie. Kevin says he has been a lousy friend, but he is still her friend, and can tell something is bothering her. Kevin deduces she hasn't been the same since she moved in with Sharon. Mariah does her best to continue to cover up Sharon's secret from Kevin, and even resorts to insulting him and Natalie some more. Kevin keeps pushing, and Mariah finally resolves to tell him everything when Sharon and Dylan come back home.
Kevin invites Mariah to continue their conversation over a cup of coffee, but Sharon says they have family plans. Kevin leaves, and Sharon confronts Mariah over almost telling Kevin. Mariah explains she is scared that keeping secrets is messing with Sharon's head, even though she knows she is taking her medication. Sharon quips that maybe she should go off of them since they don't seem to be helping her. Mariah can't believe Sharon would suggest that, and says that . Mariah says the secret is eating her up, and she needs to confide in someone she can trust. Sharon snaps that maybe she shouldn't have trusted Mariah with her secret, and Mariah reiterates her concerns. Sharon tells her to stop saying that, and Mariah tells Sharon to stop saying heinous things to her. Sharon says she is protecting her family, and Mariah says she is as well. Mariah assured Sharon she can trust Kevin, but Sharon says the truth needs to stay between the two of them.
Kevin and Mariah met at Crimson Lights, and Mariah said she was worried about her mom because she hasn't been the same since the baby was born. Mariah added that Sharon said her relationship with Dylan has lacked passion recently, and she was serving as Sharon's soundboard. Kevin joking asked Mariah why she thought she was qualified to give Sharon relationship advice. Mariah said Kevin wasn't anymore expired fed. Kevin said he was married, and Mariah added that he was divorced, so Kevin conceded neither of them was qualified. Mariah smiled and told Kevin to go to the party with Natalie. Kevin said he will only go because she told him to, and said he was just a text away if she needed him. After Kevin left, Mariah phoned and left a message for Dr. Miller.
Mariah told Sharon about her plan to meet with Dr. Miller, and pretend that she was the the one having nightmares. Natalie saw Mariah with Dr Miller at Crimson Lights, and accused Mariah of trying to set her up for the oil spill, and make her look bad in Kevin's eyes. Mariah said she didn't know what she was talking about, but then told Nick she thinks Natalie is responsible for the oil spill. Sharon questioned why Mariah was s sure it was Natalie. After, Nick left, Mariah shared with Sharon some of the suggestions Dr. Miller showed her. Mariah said she learned meditating in the Path. Mariah tried to coach Sharon through it, but Sharon wasn't listening. She thanked Mariah for trying to help her.
Sharon went off her meds, hoping to that the delusions of Sage would go away, but they only got worse. Mariah eventually realized Sharon was having delusions of Sage as well, and Sharon confessed she went off her meds. Mariah told her she needs to go back on them, and also told Sharon these delusions are caused by a guilty conscious. "Sage" continue to taunt Sharon about being a horrible mother and getting locked up in Fairview. Desperate, Sharon grabbed a bookend and went to hit "Sage", but hit Mariah instead. As Sharon tried desperately to revive Mariah, Kevin came in and asked what happened. Sharon said she didn't mean to hurt Mariah, she was just trying to get rid of "her". Kevin asked whose her, and Mariah came to.
Mariah and Kevin tricked Sharon into going to the hospital, and said they were going to make sure Mariah was alright. Mariah worried Sharon would hate her for deceiving her into going against her will. Mariah admitted to Kevin that Sharon was seeing Sage and went off her meds, hoping the delusions would go away, but they only got worse. Kevin was determined to tell Dylan what was going on with Sharon, but Mariah convinced him not to. Kevin offered Sharon an ultimatum: Either she stays on her meds, or he tells Dylan what happened. Sharon agreed to stay on the medication.
Sharon started to feel better, and encouraged Mariah to get out more and live her own life. Mariah took that to mean she should move out. Mariah told Sharon she is a constant reminder of the secret they share. Sharon assured Mariah she wanted her to stay. She told Mariah to move out if she is doing it for herself, but not to do it for Sharon because she needs her daughter. Mariah tearfully hugged Sharon, and decided to continue living with her.
Chloe returned to town with a child named Bella in tow, and Kevin wondered if he could be the father. Mariah and Kevin confronted Chloe together, and she did not hesitate to get a paternity test done. Natalie became uneasy that Chloe had returned, and was visibly bothered that Kevin could be a father. Mariah told Natalie that if she loves Kevin, then she will support him.
Mariah got roped into going camping with her family, which she didn't like at first, but she eventually made the most of it. When Mariah returned, Kevin begged her to howl him get back together with Chloe. Mariah reluctantly agreed, and did her best to talk Kevin up to Chloe, but Chloe still refused to get back together with Kevin.
Mariah tried to get Kevin to see that Chloe doesn't want him anymore, but he still refused to listen. When Mariah returned to the office, she saw Summer in a wedding dress and commented that she was a pretty snowflake. Phyllis, Chelsea, Sharon, and Chloe were all there. The women all talk about their worst marriages and Mariah had them beat because of what Ian did to him. Mariah talked about how she has always felt like an outsider, but Summer said she is one of the group.
When it was just Mariah and Chloe alone, talked turned to Kevin again. Chloe said she was surprised Kevin and Mariah weren't together, and said they were perfect for each other. Mariah said tried it, but it was just a one and done thing, and they decided to be friends again. Chloe said it doesn't have to be that way. Flowers came in for Chloe, but Mariah lied and said they were for her. Mariah got into an argument with Chloe at Faith's birthday party and quit.
Sharon started getting strange phone calls, which turned out to be from Patty. Sharon made a deal with Patty to get the phone she was using, and Mariah took it to nearby bar where she threw it on the floor. Mariah ran into Kevin, who was tracking the phone, but he didn't suspect anything.
Sharon told Mariah that Patty wanted her to break her out. Mariah advised Sharon to tell the truth, and control the narrative since Patty was asking her to do the impossible. Sharon told Mariah she juts had to get Patty transferred out of state, and make her look so crazy that know one would believe her. Sharon said she would have Patty act as crazy as possible, claiming it was part of a plan to get her transferred. Mariah told Sharon she will go, so Sharon's hands can remain clean.
Mariah went to visit Patty, and relayed the alleged escape plan to Patty, though she was scarce with the details on how they would help Patty escape. She just told Patty to get transferred an out of state facility and then she and Sharon would break her out. During a blackout, Sharon became worried when she thought she saw someone watching her. Mariah armed herself with a fire poker, though Paul and Nick insisted that she let them handle it. Paul got a call and had to leave. Nick went outside to check, and Sharon learned Patty has escaped and feared it was her. Kevin accidentally attacked Nick, thinking he was a stranger lurking around Sharon's house. Kevin stayed with Mariah while Sharon took Nick to the hospital.
Paul found out Mariah had gone to visit Patty, and asked her why. Mariah said she went to see Patty and make sure she wasn't the one making the phone calls to Sharon. When Dylan came back from out of town, he has even more questions for both Sharon and Mariah, regarding why they didn't tell him they suspected Patty. Though Sharon and Mariah managed to avert Dylan's suspicions, Mariah decided she couldn't continue to lie and always bail Sharon out of trouble.
Mariah ran into Natalie at Crimson's Lights, and found out she was working for Victor. Suspecting Natalie of helping Victor cover his tracks, Mariah asked for a job at GC Buzz in exchange for digging up dirt on Natalie and Victor. Hilary Hamilton hired Mariah as a gopher until she proved herself. Mariah informed Sharon of her new job, and said she can't continue to lie for her, and has to distance herself. Sharon begged Mariah to stay and help her, but Mariah said she can't, and that she was sorry. Mariah told Kevin she was worried about Natalie working for Victor, but Kevin turned on Mariah when Natalie told him about her new job as a gopher for GC Buzz, and she was fishing for information. Kevin felt betrayed by Mariah, and told her to never use their friendship again like that, or there won't be a friendship.
Dylan and Nick learn "Sully" is Christian
Mariah comes in while Dylan is yelling at Sharon, and Sharon asks Mariah to leave. Mariah notes that Sharon has told Dylan the truth about "Sully", and Dylan realizes she knew. Mariah defends Sharon, and Sharon begs him not to go after Mariah, and asks Mariah to leave. Mariah reluctantly does, and goes to Crimson Lights. Paul goes to see Mariah, and asks her about what Patty said. Mariah texts Kevin to meet her, and tries to tell Paul she has no idea what Patty would want. Paul isn't buying it, and Mariah admits something big is about to effect their family. She asks Paul to just leave Sharon and Dylan alone for tonight. Paul agreed and leaves. Kevin asks Mariah if she will tell him. Mariah says everything f will be revealed tomorrow, and asks Kevin to just be her friend for tonight. Kevin asks Mariah if it directly effects her, and Mariah cries that she is in too deep and could be in big trouble.
Kevin kept trying to get Mariah to tell him the truth, but Mariah wouldn't open up to him. Kevin eventually learned from Chloe that Sully was really Christian, and Sharon knew a few months ago. Kevin quickly realized that Mariah also knew and wasn't covering for Sharon. Kevin vowed to stand by Mariah and tried to get her to speak with Michael about what her options are. Mariah promised Kevin that she would talk to Michael if the story got out passed the few people who knew.
Mariah learned that Hilary found out about Dr. Anderson, and warmed Sharon that she was digging around. Sharon conceded to the fact that she will be publicly exposed, and vowed to protect Mariah from the potential fallout. After Hilary aired the story, Mariah confronted her about using her family's misery to boost her ratings. Mariah was all set to quit, but Devon begged Mariah to stay, and help him reign in Hilary's impulsive behavior.
Devon, Hilary, and GC Buzz
Mariah and Hilary's working relationship continues to deteriorate, especially after she lied to Mariah, who convinced Dylan to get on camera and tell his side of the story. Dylan does so, and defends Sharon's actions, but Hilary edits it to make things looks worse and has the viewers calling for Sharon's arrest. She later reveals that she overheard Devon wanting Mariah to keep an eye on her, and implied she did as payback against Mariah.
Devon became tired of Hilary's antics and fired her as the host of GC Buzz. He asked Mariah to fill in until he could find a new co-host. During a segment where Chelsea 2.0 was debuting a new fashion line, Mariah tripped and fell while modeling one of the dresses. She looked up and saw Hilary smirking. Mariah got up and finished the shoot, though she felt utterly humiliated, especially when people started making fun of her. Sharon and Faith do their best to comfort and make Mariah feel better.
Overtime, Mariah realizes Hilary tripped her with the cord. At a benefit for recovering addicts, Mariah is in charge of the teleprompter, and during an auction that Hilary his hosting, Mariah tricks Hilary into publicly admitting she tripped Mariah. Devon storms off, and gets into a car accident. Mariah is filled with remorse, and when Devon loses his memory as a result of the crash, she stays quiet. Hilary tells Mariah she and Devon have worked things out, and Mariah takes that to mean that Hilary came clean to Devon and they worked it out. When Mariah implies that Hilary did something nefarious, he pressures Mariah to tell him everything, and his memory slowly returns as she explains everything.
Devon makes Mariah Hilary's co-host, and Hilary plays the video of Mariah falling, and apologizes after admitting she tripped Mariah on purpose out of jealousy and spite. Devon and Mariah are impressed by Hilary's admission. Mariah finds out Dylan left Sharon, and is heartbroken and angry at Dylan. Sharon assures Mariah she is fine and says they need to be strong for Faith's sake. Gloria Abbott Bardwell comes to GC Buzz and says that she was raped. Mariah airs the segment without fact checking, and Hilary has the segment cut when learns it refers to Jack Abbott. Mariah later realizes her mistake, and assumes Devon is going to fire her, but is relieved when he wants to keep her on.
Devon and Hilary get ready to finalize their divorce, but she wants complete ownership of GC Buzz. Hilary convinces Mariah to help her convince Devon to sell GC Buzz by promising her job security and to to keep her on as Co-host, so Mariah agrees and convinces Devon to give Hilary GC Buzz with a written contract, stipulating that she can't fire anyone until after the first year.
Dating Devon, Working under Hilary
Devon asks Mariah out on a date, and she accepts. They go to the top of Newman Tower, but realize that they aren't for the ritzy food, so instead go to The Underground. There, they see Hilary with Jordan Wilde, a photographer that Hilary had met while doing a segment promoting Brash & Sassy's new men's cologne. Mariah and Devon kiss while Hilary's watching, and tensions escalate with Mariah and her at work. Hilary re-brands the show "The Hilary Hour", and mainly promotes herself. On air, the two women often snipe and take jabs at each other.
Kevin and Sharon soon found out about Mariah and Devon's relationship. They are happy for her, but Sharon cautions Mariah, worried that she is just a rebound. Mariah assures Sharon she will bolt at the first sign. Soon after, Devon and Mariah almost have sex at his place, but Mariah pulls away. Kevin invites Mariah to his wedding to Chloe, and she brings Devon as her date. Mariah joins the bachelor party where she meets Scotty Grainger. Gloria wants Mariah to seduce Kevin away from Chloe, but Mariah refuses.
The wedding doesn't go as planned, with Chelsea finding evidence that Chloe murdered Adam, and Chloe flees. Mariah is furious that Chloe once again deceived and hurt Kevin. She contemplates airing this on GC Buzz, but Scotty blasts Mariah for wanting to air this story and not thinking of Kevin's feelings. Mariah takes Kevin to the movies to cheer him up, and sees Sharon with Scotty. After the movie, Mariah gets to know Scotty better and he apologizes for attacking her like he did at Chloe's wedding. Mariah is happy that Sharon is moving on.
Mariah and Devon finally sleep together, and she and Hilary get into a fight about it when Mariah wears one of Hilary's dresses to work at Devon's insistence. Hilary tries to make Mariah doubt her relationship with Devon, and they often clash over it as Mariah tries to flaunt the relationship in Hilary's face and claim she and Devon are having great sex, but Hilary always manages to make Mariah walk away doubting Devon's commitment to her.
Mariah quickly becomes friends with Noah's girlfriend Tessa. They hang out and watch a romantic comedy at Sharon's, and Tessa sticks up for Mariah to Hilary, who needles her about her relationship with Devon. As Mariah and Tessa become closer, Mariah starts to become bothered by Tessa's closeness to Noah. When Devon purchases tickets to a music festival, Mariah enthusiastically invites Tessa and Noah without talking to Devon first, but Devon allows them to come. In Mariah's hotel room, Tessa is helping Mariah get ready and they have a heart to heart after which Mariah kisses Tessa. Mariah instantly regrets it, and Tessa is fine with it, but they act like it never happened.
Tessa and Mariah hear about a girl named Crystal that Sharon is trying to help escape a sex trafficking ring. Tessa confesses to Mariah that Crystal is her sister, but swears her to secrecy, though she ends up telling Noah and Sharon eventually. When Sharon says that she suspect that Alice Johnson, Cassie's former adoptive mother, is involved in the sex ring, Mariah and Tessa drive up to Alice's place, but Alice slams the door in Tessa's face.
Kevin returns to town, and Mariah tells Kevin about her feelings for Tessa. Kevin encourages Mariah to be honest with Tessa, so Mariah tries to tell Tessa how she feels, but changes her mind when Tessa says Mariah is like a sister to her. Tessa later asks Mariah to help her as she is determined to help Crystal. Tessa kidnaps Alice, and they take her to a barn in the ranch. Mariah gets Alice some water, and when Mariah tries to give it to Alice, Alice thinks she is seeing Cassie and passes out.
Mariah decided to pretend to be Cassie. She tells Sharon everything, and she agrees to help Mariah dress as Cassie, so Alice thinks that she is really seeing Cassie. Mariah guilts Alice, who claims she cares about the girls, but Mariah asks her if she would be okay with Cassie doing what the girls do, and has her imagine what it be like if sweet innocent Cassie was being a prostitute. Alice cries that she would want better for Cassie, and finally breaks down and agree to help them.
Alice later sees Mariah and they confess that Mariah is Cassie's twin sister. Sharon and Mariah explain their story to Alice, who is disgusted that they would use Cassie's memory like that. Sharon says Cassie would have spoken to her like Mariah had. Alice arranges to have Crystal returned to Genoa City, saying she cleared it with the boss. They meet by Cassie's grave, Alice's associate, Leo, brings Crystal while Sharon, Mariah, and Tessa hide.
Just after Leo hands Crystal over to Alice, he hears a noise, and pulls Sharon from the bushes. Alice tries to get Leo to let Sharon go, but he won't. Mariah throws a rock at Leo's back, and Sharon knocks Leo's gun away. Alice grabs it and Mariah and Tessa emerge from the bushes. Alice orders Leo to leave, and Mariah and Sharon watch as Tessa and Crystal reunite, but the reunion is short lived as Crystal has to leave town to go into witness protection.
Tessa moves in with Noah, and Mariah starts pushing her away, unable to deal with her feelings. Sharon realizes that something is bothering Mariah, and Mariah eventually admits to Sharon that she has fallen for Tessa, which has diminished her feelings for Devon. Sharon is surprised, but supportive. She tells Mariah to go talk to Tessa, so Mariah confesses her feelings to Tessa, who admits she feels the same way, but wants to stay committed to Noah as she has finally built the life she wanted for her and her sister. Mariah eventually decides to break up with Devon, but they agree to stay friends.
Unable to deal with her feelings, Mariah starts avoiding Tessa, who keeps trying to force encounters between them. When Tessa is being interviewed on GC Buzz, Hilary breaks the story that Tessa stole Nikki’s gun. Tessa jumps to the conclusion that Mariah told Hilary, and when Devon reveals Hilary got the story from him, Mariah is hurt that Tessa would think she would betray her like that and a rift forms in their friendship.
Journal and Exposure
At Sharon’s encouragement, Mariah starts to keep a journal that she writes her feelings in. Tessa tries to talk to Mariah, who refuses to talk to her, so Tessa steals Mariah’s journal, uses it to write a song, and casually drops it off at GC Buzz when she is going to debut the song. As Tessa sings the song, Mariah recognizes the words as her and accuses her of stealing her journal on air.
Devon and Noah try telling Mariah that the song was hit a coincidence. Devon requests to see Mariah’s journal, so he can verify her claim. Tessa tries to talk to Mariah and get her to change her mind, so Devon can release the song, but after Tessa starts talking to Mariah about her feelings, Mariah interprets this as Tessa trying to manipulate her, and digs her heels in.
Mariah shows Devon her journal, but he still refuses to pull the song, so Mariah threatens to sue. Noah approaches Mariah and accuses her of keeping secrets from him. He admits that he thinks he and Mariah are close, and feels she should be able to tell him anything. Mariah brings Noah the journal and he reads it. He admits her claims are true, but is confused why she is so secretive. Mariah silently and tearfully gestures for Noah to turn the page, which had Mariah admitting to kissing Tessa in it. Stunned and hurt, Noah hands Mariah back her journal and walks away as Mariah cries.
Working with Tessa
When GC Buzz was acquired by Hamilton Winters, Devon realized that Mariah and Tessa would be in each other's orbits once more. Not wanting there to be any tension, he told them to make peace and talk things over. Tessa apologized again, adding that Mariah had to admit they created an amazing song together. Tessa said that when she read the journal, it was like she could hear Mariah's voice in her head, and all the other lyrics of the song fell into place so perfectly. Mariah started to understand Tessa's viewpoint, and was willing to cooperate so that they could work together peacefully. Later, she found a USB in her bag that Tessa had put there. Their song was on it, and Mariah listened to it with a thoughtful expression.
Mariah realized that Tessa was homeless again and sleeping in Devon's office. Instead of exposing Tessa, she went and told Sharon. They were overheard by Nick, who talked about how he had some vacant, affordable apartments due to construction that was taking place. Mariah really wanted Tessa to find a home, so she asked Nick if Tessa could rent one of the apartments. Sharon and Nick were confused why Mariah would want to help Tessa after the whole journal incident, but even so, Nick agreed to offer Tessa an apartment. When Tessa found out what Mariah had done, she was extremely thankful.
Devon thought it was important to discuss the future of GC Buzz, and what direction it would go in now that it was operating under the Hamilton Winters umbrella. He invited Hilary, Tessa, and Mariah to Noah's restaurant so that they could have a meeting, making sure that Noah wouldn't be there at the time. Devon wanted their input on what they could do to bring the Hilary Hour to its full potential. Hilary had many ideas which mainly centered around herself, even suggesting they do a story about her pregnancy (even though she might not even be pregnant yet). Hilary then went on to say that Mariah had no goals, since Mariah had said she was content with her current job. Tessa stood up for Mariah, saying that there's nothing wrong with Mariah enjoying her job, and the viewers resonate with Mariah because of it. It turned out that Noah was there after all, and he overheard what Tessa said. This prompted him to get a few drinks at the bar. First Mariah went to talk to him, then Tessa. When Noah tried to punch Devon, Mariah helped her brother up since he had fallen to the ground.
Before coming to Genoa City, Mariah seemed to have very skewed morals. She would commit crimes to get what she wanted, and even slept with Tyler's boss, while they were engaged, so he wouldn't press charges. Tyler broke off his engagement to Mariah, and moved to Genoa City. Mariah followed him, and tried to sabotage his relationship with Abby in order to get him back.
While looking for a job at Crimson Lights, Mariah encountered Victor, who hired her to gaslight Sharon because she looked exactly like Sharon's deceased daughter Cassie. As Mariah spied on Sharon, and posed as visions of Cassie, she started to have sympathy towards Sharon's pain. She realized how much Sharon loved and missed Cassie. After Mariah drove Sharon to have electro shock therapy, she brought her a vase of flowers.
When Mariah was found out, she was stunned by Sharon's kindness towards her. When Mariah was arrested and extradited back to Portland, she turned to Sharon for help, and Sharon bailed her out. Mariah was grateful and took a job to pay her back. She even issued a sincere apology to Abby and Tyler.
Mariah instantly took a liking to Sharon's youngest daughter, Faith, and the two formed a close bond. Though Mariah has started to like Sharon, she also developed a crush on Nick, and tried to seduce him while he was engaged to Sharon. After Sharon threw her out of her life, Mariah was furious with herself that she screwed up a good thing. When she found out Sharon was her biological mother, Mariah resented Sharon and rejected her attempts to bond with Mariah. Though she reluctantly agreed to be a part of Sharon's wedding, she secretly accepted money from Victor to continue to try and find out Sharon's secret and wreck her life.
Mariah's friendship with Kevin really helped her grow as a person. He offered her words of encouragement and did not judge Mariah no matter what she did. Mariah also became friends with her co-worker Austin, and formed a rivalry with his wife Summer. Summer was jealous of Mariah's friendship with Austin, and also hated her for what she did to Sharon. Though Mariah knew what she did was wrong, she wasn't one to be pushed around or verbally abused. Mariah even wanted to mess with Summer and Austin's marriage as payback, but Kevin convinced her not to. Mariah wanted to learn how to be a better friend to Kevin, and even seemed to develop some feelings for him. She even let him manipulate her into kissing him under the mistletoe, but they were interrupted.
After Nick blasted Mariah for her cruelty towards Sharon, Mariah did some thinking, and finally realized she had a mother, who wanted her in her life. Mariah started to let herself be embraced by Sharon, though it took a little prodding to get her to admit it. Mariah stood by Sharon when her secret was exposed, and was finally truly happy for the first time in her life. She had a mother who adored her, a baby sister she adored, a brother who embraced her as well, and a great friend in Kevin.
On her birthday, Mariah decided to wish her deceased twin a happy birthday, and went to visit her grave. Mariah's family wanted to do something nice for her birthday, but Mariah felt like she was being compared to Cassie, often dubbed the "good twin" by Mariah when she was upset. Mariah's impulsive nature returned. She kissed Austin, and desperately tried to push Kevin away. Kevin stood his ground, and refused to let Mariah push him away. Mariah realized what she had done was wrong and offered apologies to both Summer and Austin. She had left herself vulnerable and was really hurt when Summer told her that know one would ever love her.
When Sharon lost custody of Faith, She tried to blame Mariah for it. Mariah desperately tried to assure Sharon that she was on her side, but Sharon would not hear none of it. On the verge of tears, Mariah finally snapped and told Sharon off. Despite this, she didn't seem to hate Sharon, and told Dylan that Sharon needed him. Since the fight with Sharon, Mariah hasn't said one ill word about Sharon, and wouldn't even let Summer trash talk her. Mariah also blatantly said she was upset that she had helped Nick destroy her mother's life, and even referred to Sharon as her mother for the first time ever.
At the Cabin, Mariah started to ease up on the insults and began to have fun, though she still had a negative reaction to Abby asking for her help. Mariah was devastated when Austin was murdered, but was also on board with Kevin's plan to cover up Austin's death when Summer thought she had killed him (though she claimed she did it because Austin would have wanted her to protect Summer). Mariah was frustrated with Summer because she couldn't keep her emotions in check, and would often lash out and insult her.
Mariah did feel shame over the fact that she didn't tell Summer about Austin and Abby's affair, and even seemed to soften towards her. Kevin firmly believed that Mariah was trying to protect Summer. Mariah was also quick to forgive Sharon, and firmly believed she was innocent of Austin (and later Courtney's murder).
In late 2015, although Mariah would still call Summer "snowflake" they were on friendly terms and Mariah even advised Summer to stay away from Luca, and wait for Kyle. Mariah's newfound morality was comprosmised with the arrival of Natalie and the creation of PassKey. Mariah became obsessed with getting rich and even attempted to guilt Summer into lying for her. She was completely oblivious to how much Summer was hurting her. The fact that Mariah lied at the deposition for money when she refused to lie for Sharon at the custody hearing, showed how much greed had corrupted her.

Abby: For all we know, I could have kissed you.
Mariah: You're not my type.
Abby: I've got some more punch.
Mariah (sarcastically): Oh goodie!
Abby: Mariah could you give me a hand?
Mariah: Really? is that why I was invited to this party; to cater it?
(Kevin gives Mariah a look and loudly clears his throat)
Mariah: (big dramatic sigh) fine!
Abby: Thank you.
Mariah: (to Summer) I just helped Nick destroy my mom's life and you think I am happy about it!?
Mariah: That was a question, did Snowflake not to home last night?
Summer Why are you so interested in what's going on with me and Austin. Are you waiting for your chance?
Mariah: It was just an observation, but since I hit a sore spot, let's talk about it some more.
Kevin: Or not, not is a great idea.
Mariah: (to Nick) What? You're gonna read me bed time stories and tie ribbons in my hair? It's too damn late for that!
(Mariah taunting Summer about Abby & Austin's affair)
Mariah: Great, then let's all hop into our expensive cars, and drive straight to the police station. Oh wait, I don't have an expensive car, maybe I can borrow the one that you bought for Austin, or was that Abby; I forget.
Summer: If you don't shut your mouth.
Mariah: What, you're going to kill me, Summer?
Mariah: Well we're screwed.
Kevin: Are you always this negative?
Mariah: No, I am positive. I am positive once they tell the police that Austin was murdered, and we tried to cover it up; they are going to throw us into the nicest jail in Genoa City, how is that for positive?
Kevin: You have something she [Abby] does not.
Mariah: (giving two thumbs up) An awesome job at the Underground?
Mariah: (To Kevin) What, this is you sane? Oh my god, I can't wait to see you crazy.
Mariah: (to Sharon): I do miss talking to you though.
(Sharon hugs Mariah)
Mariah: Don't miss the hugs so much.
Mariah: (to Summer) So when it comes to you, not only are we the weaker sex, but we are also the dumber sex.
Mariah: Finally now we can juat sit back and let the police do their job
(Kevin pulls out his laptop)
Kevin: Uh huh
Mariah: You're using your fingers
Mariah: So, you promised you wouldn't do that
Kevin: Yeah well when I made that promise, I had my fingers crossed.
Mariah: I probably shouldn't be asking this, but what exactly are you looking for?
Mariah: Damn it Kevin, take a break from whatever you are doing, and call me. Oh and I hopefully remember that the cone of invisibility is not real.
Mariah: (to Summer) You know what's funny about your almost birthday Snowflake? Is that I almost care.
Mariah: Try "Kevin#nicebutt"
Kevin: You're crazy that's never going to-
Mariah: Wait, did that actually work?! (under her breath) I hate her, I hate her, I hate her!
Mariah: Now get in there tiger, and make momma proud.
