Mr. Lowe Sr. returns with fireworks for Gigi's birthday and gives Vivian a gift, but Vivian skips the celebration to rest for upcoming exams. He calls Gigi "your future granddaughter-in-law" and asks Isaac to escort and look after Vivian. Family members say Vivian has been acting strange and insist she won't be allowed to go far; they point out Quinby is close to home so she can be kept under Isaac's watch. The episode turns when Vivian tells Isaac, "I'm leaving you soon." The announcement leaves Isaac and the family's plans suddenly unsettled.
