Talya and Brandon have appeared to be dating before the series started. When Callie is taken in by the Fosters though, she gets almost immediately jealous of Brandon's growing relationship with Callie. She ultimately does not like Callie and becomes her enemy. In Hostile Acts, she read Callie's private journal without her knowledge, strengthening her dislike. In Quinceanera, she tells Callie to stay away from Brandon, and after Callie tells him about his girfriend's jealousy, he breaks up with her. Brandon is oblivious to Talya's jealousy though, and seems to like Talya a lot. In Quinceanera Brandon yells at Talya and says, "I can't do this anymore, I'm done" and that's the end of their relationship.
In Clean, Talya attempts to give Brandon two tickets to a concert performed by his favorite band. He rejects her offer initially, not wanting to do anything with her. At some point, he agrees to go to the concert with her. After the concert, they go to get coffee. In Vigil, Talya shows up at the hospital to support Brandon although it is unknown if their relationship is back on. In I Do, they are seen holding hands while talking about wedding shopping for his moms. She is seen less jealous over Callie now as she invites Callie to join her and Brandon to go wedding shopping. After Brandon and Callie kiss, Brandon and Talya's relationship ends and she realizes it is Callie that he actually wants and leaves in tears, insisting that Callie is only going to hurt him.
