When my parents first heard I was gay, they kicked me out. They said I had debased the entire family and that they couldn't love me anymore until I had changed. But Andrew said that I should be ashamed of them because they were too stupid to know how great I was. That's the thing about Andrew, he does not take crap from anyone. How can you not love someone like that?
Justin is Andrew's first boyfriend. Justin first appears as John Rowland's room-mate, and is privy to his affair with Gabrielle. Justin is in denial about his sexuality and tries to blackmail Gabrielle into having sex with him to convince himself he is heterosexual. She, however, refuses but helps him in accepting his true sexuality. Afterwards, his relationship with Andrew becomes more serious. Ironically, Justin is later beaten up by Carlos Solis, who mistakenly believes he is having an affair with Gabrielle.
Andrew confides in Justin that he had to stop loving his mother because he did not want to get hurt any more, and that Bree had to be punished because she said he was damned for his sexuality. When Andrew needs fuel for his emancipation bid, he forces his boyfriend to hit him and passes off the bruises as having been inflicted by a presumably drunk Bree. Justin is also with Andrew when he tells his mother he will accuse her of molesting him if she does not let him go. Justin tends throughout his screen time to do whatever Andrew wants, although he often appears thoroughly embarrassed by Andrew's behaviour towards his mother.
Justin is heartbroken when he finds out Andrew is planning to move to Rhode Island with his grandparents, and when Bree asks him why, replies his parents kicked him out when they first heard he was gay. Andrew told him he should be ashamed of them because they were too stupid to know how great he was, Justin asks Bree how she cannot love someone like that. Bree then persuades Justin to supply her with gay magazines and videos, which she plants among Andrew's things for his grandparents to find. They leave Andrew behind and revoke his trust fund. Having seen Justin's love for Andrew, Bree becomes more accepting of their relationship, and regularly invites him to dinner. He is last seen at a dinner with Keith and the Van de Kamps in I Know Things Now. After Bree leaves Andrew on the streets, Justin is not seen again and it is implied the two broke up.
