Things around Erica are not going well. Sam, who is still staying with Erica and Ethan, has just been served divorce papers by Josh, who wants to take her for everything. And Erica loses two important people in her life. First, Brent no longer wants to associate with her as he sees them as being on opposite sides of a Cold War. And second, Kai no longer wants to see her after her admission to him that she has feelings for him. Not wanting to fall into what he sees as the bad life he lived in 2019, Kai quits his job at Goblins without telling Erica in hopes that she can go on with her happy life with Ethan. Erica, in her regular therapy session, wants specifically to deal with the issue of Kai, which Dr. Tom refuses, he stating that her therapy is about her and not Kai. After a fight, Erica walks out of her session. Their fight reminded Dr. Tom of his own strained relationship with his street-wise daughter, Sarah, whose whereabouts he now does not know. To help him understand what is happening between himself and Erica, Dr. Tom is sent back by Dr. Naadiah to his last meeting with Sarah. This trip back may fundamentally change Dr. Tom's relationship with Erica, and by association Kai.
