Simon meets up with an old girlfriend, Sasha and they both try to catch up on their personal lives. Lucy and Robbie argue over who should tell Mary about their emerging relationship. Matt worries that a young woman in his study group might be a victim of physical abuse at the hands of her belligerent boyfriend. Elsewhere, Eric's sister shows up at the house with her toddler and annoys Annie as she tries to prepare a lesson for her class.

Robbie is happy with his new hot Latina girlfriend Joy Reyes and persuades her rich, devoutly Catholic father Ramon Reyes (for now) of his honorable intentions. The garage apartment squatters' resolve is self-sabotaged by their rivalry to get what shouldn't be Mary's and Ruthie's scheming. In the end return under the maternal yoke and make up (more or less forcibly) with Mary, who meanwhile repents, but Eric wisely doubts her sincerity and rectitude.
