The cast is invited to Emma's quinceañera, where Jonah especially feels awkward, Mateo and Cheyenne try to get Amy to cry, Glenn expresses his admiration for Latino culture, and Dina and Garrett again confront the nature of their relationship.
Tropes:
- Birthday Party Goes Wrong: Emma's fifteenth birthday gets muddied by Jonah's clumsy attempts to win her over and the fact that she's secretly high.
- Hormone-Addled Teenager: Dina's very low-cut dress draws the attention of a few.
- Open Mouth, Insert Foot: Jonah loses it a little when prompted to give a toast. He spirals about how he's not really a part of the family yet and closes with a line about her sexuality.
- Operation: Jealousy: Suspecting that Garrett's still into her, Dina dances with a horny fifteen-year-old boy just to get him jealous.
- Winning Over the Kids: Jonah tries to win over Emma.
