Kai returns. Based on what he told her last time he saw her, Erica is certain that this trip is the one where the two of them will have sex. Because the encounter already happened in Kai's past, Erica is unsure if she has the ability to change that if indeed she does not want to have sex with Kai, which based on circumstance could not blossom into a full fledged relationship. Erica brings this conundrum up at group therapy. Beyond what Erica sees as a slight glimpse of jealousy on Adam's part to this news, Dr. Tom reacts in such a way that angers Erica and that could threaten her therapy with him altogether. What Erica is unaware of is that Dr. Tom is dealing with something in his own life out of need. Dr. Arthur has been concerned that Tom has been hiding behind work rather than take time to reflect and enjoy his own therapied life. The situation which he and his wife Marjorie are facing is the return of their daughter, Sarah, who is very much in need of help but whose actions show that she is unable or really unwilling to clean up her life. This situation makes Tom feel helpless, unlike how he feels when he is dealing with his patients. Meanwhile, Sam has gone from one extreme to another in her public dealings with Lenin, this time overcompensating for their professional disparities.
