She lives with her pregnant sister Bessie, and she works for her at the Ice House---the Potter family restaurant. She is frustrated with having to deal with work and taking care of her sister along with significant helpings of teenage angst. Nonetheless, Joey manages to be helpful with the birth of Bessie's son, Alexander, as does their critical neighbor, Evelyn Ryan.

After a huge argument, Joey decides to break up with him, even though for the first time they both say that they love each other. She says that she wants to "find herself", and so she breaks up with him.
