In the present, Randall is upset that Kate has been made Rebecca's health care proxy, but before he and Beth can discuss it, Deja interrupts. She's angry because Malik broke up with her and told her what Randall said. She tells Randall she hates him and that he's not her father.
The next morning, Randall and Beth discover that Deja has run away. She's gone to Boston to try to resolve things with Malik. Randall wants to run after her. Rebecca insists on accompanying him on the trip.
