Peyton finds Lucas and tells her about the pregnancy. She tells him if she is pregnant then he has to be there for her, so she guesses it is goodbye as Lucas won’t talk to her anymore. He is confused as she tells him what Derek overheard but sends him to talk to Brooke.

Brooke goes to see Shelley and asks what happened at the summer camp. She admits that she got pregnant at church camp, it wasn’t sleeping around that got her thrown out, she had an abortion and the ordeal clearly still lives with her. Dan looks through an old photo album of his highschool prom with Karen. He remembers the therapist asking if he still loves Karen which Dan replies maybe to and the counselor suggests maybe because Keith is dead, he has won now.
