Dexter - S02E12 - The British Invasion

Lila finds Doakes imprisoned in the cabin, and realizes that Dexter is the Bay Harbor Butcher. She ignores his pleas for help, and kills Doakes by setting the cabin on fire. Doakes is found dead, and because the evidence of the Bay Harbor Butcher killings indicates him as the criminal, the case is closed. Debra and Lundy try to resolve their relationship problems and Dexter reconciles with Rita. When Lila threatens Rita's children, Dexter realizes that he needs to find a solution to Lila's obsession with him. After Lila attempts to kill him, Dexter follows her to Paris and kills her.
