Donna is back on the dating scene thanks to TMI's assistance in setting up a Tinder account. Pippy hates the fact that her mother has moved on from her father so quickly. 

Pippy prompts TMI to sell her apartment so that they can begin to start their lives together as a married couple. TMI is unsure how to feel because she still doesn't have the approval of her relationship with Pippy from her parents. She then decides to call her parents to say she still loves them even though they don't accept the fact she's gay.
