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 in the comic book art lining Seth's bedroom wall.)

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. Back at the Cohen's house, the odd dinner party continues. 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".
