The police find Sussman's body no longer on a hook but now arranged to look like a suicide. Dexter knows this is to throw the police off the trail. And it works, as Miami Metro triumphantly closes the Brain Surgeon case. However, the real Brain Surgeon leaves disturbing trophies on Vogel's doorstep for "His" and "Hers". Dexter pursues another of Vogel's former patients, Ron Galuzzo, who sells workout equipment at the mall. Vogel finds Dexter's love for Debra unusual and questions why Dexter didn't kill her when she discovered his secret, implying that he is not a "perfect" psychopath. Debra sloppily acquires a new client at work. Quinn's preoccupation with Debra and lying about why he left at 4AM causes friction between himself and Jamie, and Batista begins to lose faith in Quinn's ability to pass the sergeant's exam. Dexter learns that Galuzzo is a cannibal, and Galuzzo's job helps find the most fit victims to target. Dexter tries to convince Debra she's still a good person but after her work client wouldn't see the obvious evidence of adultery in front of her, Debra spirals out of control and drunkenly tries to confess to killing LaGuerta to Quinn. Quinn calls Dexter and he quickly arrives with Vogel. Debra goes berserk and in desperation Dexter injects her unconscious. Vogel grabs Debra's written confession just in time. Dexter kills Galuzzo.
