With the vision of his brother Brian beside him, Dexter disposes of Nick's body in the ocean. Debra faces scrutiny because her department's case clearance rate is so low. Dexter finds out that Rebecca Mitchell and her mother (the daughter and wife of the Trinity Killer) have been killed, which son Jonah blames on his father (who only Dexter knows is dead). He and Brian drive to Nebraska to possibly kill Jonah before he can follow in his father's footsteps. When confronted, Jonah reveals that his mother blamed her children for their father's actions. Rebecca committed suicide, and when Jonah found her, he became so angry that he beat his mother to death. Despite Brian's protests, Dexter lets Jonah live, telling him to forgive himself. This leads to a heated argument between Brian and Dexter, and Dexter runs him over with his car. Meanwhile, Masuka and his new intern find a lead related to Doomsday. Travis also tells Gellar that he is done working for God, to which Gellar angrily objects but ultimately agrees to. Dexter picks his father back up on his way back to Florida.
