She leaves in the thirteenth episode of season one ("Dreams Come True"), after getting a job on a soap opera in New York City. Peter then entered a relationship with Lexi, but he broke up the relationship because he still had feelings for Amanda.
Peter attempted to get Amanda back with no success, so he began a relationship with Eve. Although Lexi tried to break them up, Peter and Eve stayed together.
The couple then gets married and decides to have a family, and Peter says they will name their kids after the former residents of Melrose Place, promising Amanda they will not name any of their children after Kimberly. Brooke is introduced in season three as the daughter of Hayley Armstrong, a wealthy businessman, and she is an employee at D&D Advertising.
Billy then decides to leave her for good when she becomes too controlling.
In season four, Brooke's seductive behavior and spoiled-rotten personality lead many to despise and envy her: in the course of the episode "No Lifeguard on Duty", she ends up locked out of her hotel room and unable to get her stuff out of it, tries to seduce Billy and has him furiously declare that he doesn't even care enough about her to hate her anymore.
Despite their issues the two get married anyway, which puts a strain on Brooke's relationship with Hayley, as he no longer wishes to support her financially.
When her father dies, she finds out that he had cut her out of the will.
He later works for a newspaper, and later starts working at D&D Advertising with Alison and Amanda. In season one, he dates Amanda briefly and she becomes pregnant with his child, but soon miscarries. He and Alison get engaged in season two, but she gets cold feet on the day of the wedding due to personal issues with her father.
In the first season he is an aspiring writer and taxi driver.
In season 5, he begins a romance with Samantha Reilly, and in season 6 they get married.
The marriage ends after Samantha has an affair with baseball player, Jeff Baylor, the same time that Billy became interested in Jennifer Mancini. Alison has many romances during the show, perhaps the most notable being with Billy Campbell.
When he dies, she finds out that he tricked her into signing divorce papers, and therefore Alison did not receive any of his money.
Eventually, Alison leaves D&D advertising, and she was working at Shooters, during which she fell in love with Jake. Peter Burns first appears in the third season as the chief of staff at Wilshire Memorial Hospital, where Michael, Kimberly and Matt also work.
After Brooke's death, Billy became very angry and hostile towards others.
