At the police station, Dexter discusses another murder case being handled by James Doakes (Erik King), a detective who dislikes him. Later, Dexter watches Jamie Jaworski, a murderer who escaped justice due to a faulty warrant, and breaks into his home to find evidence. Once he confirms that Jaworski is guilty, Dexter meets with his girlfriend Rita Bennett (Julie Benz), a former victim of domestic abuse victim; Rita has two young children, Astor and Cody. While on a date with Rita, Dexter finds another murder scene with no traces of blood, this time with the victim's head missing.
