Justin lives with his mother Hilda, his aunt Betty, and his grandfather Ignacio. His biological father is Santos who is murdered in the finale of Season 1. Justin is quite fashion conscious and exhibits model-like behavior, such as commenting on his own body image and being food conscious. His knowledge about the fashion industry, from reading MODE, where Betty works, and watching Fashion TV, is among the reasons his aunt influences him. Justin exhibits stereotypical gay behavior which propels some of the storylines including his involvement in performing arts. As he is still a young teenager, his adolescent sexuality is still being developed in storylines. It is revealed in Season 4 that Justin is gay.
