Volchok turns to Sandy for advice, without Ryan's knowledge. Summer prepares to face life in Newport as she returns from Brown. Meanwhile, Julie finds herself alone on Thanksgiving when she is not welcome in the Cohen's house.
Thanksgiving at the Cohen house!
Tensions are still running high among the family because of what happened in Mexico. Summer balks at coming home but after a conversation with her needy father she agrees to join her dad in "crazy town".Julie is persona non grata at the Cohen house for Thanksgiving after masterminding the mission for Ryan and Seth to chase Volchok in Mexico.
Ryan is still mad at Seth and is determined to get revenge on Volchok. Kirsten forces Seth and Ryan off to the grocery store in an attempt to mend fences between them. They run into Julie, who corners Ryan to update him on her PI's search for Volchok. Sandy secretly takes Volchok on as his client, making arrangements to turn himself in. Sandy believes this is the best way to let Ryan move on with his life.Ryan sees Sandy with Volchok, outraged by the situation, he is determined to get some answers. Not happy with Sandy's perceived interference, Ryan's quest for Volchok continues. and now that he knows Volchok is in Newport, Ryan's sure he'll get him. Summer avoids an intimate moment with Seth by rambling about poverty in America. (Of course it's not Seth that she is avoiding... it's the image of Marissa (CosmoLass) in the comic book art lining Seth's bedroom wall.) She drags Seth off to a homeless shelter and they end up bringing home a handful of smelly and disheveled "guests" to the Cohens for Thanksgiving dinner.
Finally, Sandy takes Ryan to the hotel where Volchok is. Ryan punches Volchok twice, but passes up the chance to kill him, so that Volchok will "have to live with what he did". They end up discussing their feelings about Marissa's death and emerge together, at which point Volchok is taken into custody.
Summer goes to see her dad and finds Julie sitting sadly at the elegant Thanksgiving dining room table alone. Julie told Summer that they eventually have to get over Marissa. From the airport, Summer leaves Seth a phone message saying that she has decided to go back to Providence early because she's not ready to face the past. Neil reveals to his daughter he is taking a position at Seattle Grace hospital.
Back at the Cohen's house, the odd dinner party continues. One of the homeless men finds his dog in Kaitlin's lap, much to the youngest Cooper's chagrin. The doorbell rings and Sandy opens the door to a teary Julie who apologizes. She is invited to join the meal, but instead she and Ryan head out to the poolhouse to talk alone. Julie asks Ryan to "tell me about her". He begins by sharing his memory of the first time he ever saw Marissa. Talking about her smile, they share memories of Marissa.
