Raul realized he was not the one who had Mac’s heart, and left hr. Mac and Billy began being drawn to each other again, but it wasn't until Jack Abbott arranged for Billy and Mac to be trapped in an elevator that they realized that they truly belonged together. Jill decided make peace with it. Things went well for several months. Billy helped Mac admit that she had run away because her stepfather Ralph had molested her, and her mother wouldn't believe it. Later on, Billy shared his feelings with Mac. He tried to avoid pressuring her, but couldn't accept that she was not ready, so they broke up. Then Mac's stepfather, Ralph, showed up in Genoa City and began stalking her. He coerced Mac's mom into helping him steal from the Chancellor Estate. Amanda let him into the mansion while all were at the prom, but Mac returned home unexpectedly and was met by Ralph.
Billy confronted him, and whacked Ralph over the head with a fireplace poker. Billy took Mac to hide out in their special place, the old Abbott playhouse. Thinking they were doomed, Billy and Mac realized they still loved each other. Ralph, disguised as a cop, talked Raul into telling him places where he might find Billy and Mac.

Ralph knocked out Billy by whacking him over the head with a rock and grabbed Mac, but Larry Warton showed up in time to rescue her.

Years later, Mac showed up at Billy's wedding to Chloe Mitchell after they said "I do". (This was shortly after it was revealed that Katherine really wasn't Jill's mother, so Billy and Mac aren't related). Mac was engaged to Raul, but she broke it off to be with Billy. Billy cheated on Chloe with Mac he and Chloe evantually divorced. Billy and Mac were together for a while, until Mac decided he wanted to have a baby for Lily Winters and Cane Ashby.
