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.
