Previously: Doakes caught Dexter as he packed Jimenez's body into his boat in the Everglades. They struggled, and Dexter put Doakes in a cage in the cabin. Nobody puts Doakesy in the cage! Sorry. LaGuerta told Deb that not reporting Doakes's phone call to her was "worth the risk," but Lundy saw it differently, telling her she compromised her own integrity as an agent of the law, and that she couldn't be trusted. Go Lundy! Dexter and Rita started to patch things up. Lundy and Deb got into some silly beef over what's going to happen when the whole BHB mess is done with. Angel and Lila boned (roughly), and then she took a bunch of roofies to make it look like he raped her, which is severely uncool. Dex decided he'd frame Doakes really hard, so he put his fingerprints all over his knives when Doakes was passed out, and then planted them by a dock where he knew a diving class would find them. Dex also found out from Matthews that Harry actually committed suicide, a rather demoralizing discovery.
We're in the cabin on the same night we left off last episode, and Dexter VOs, "I always thought hardened arteries squeezed the life out of my father." Dexter starts taking down the plastic wrap he used for Chris Harlow's killing. "But it was me. Harry gazed into the eyes of his creation and saw evil, pure and simple. My evil. It killed him." "That shit about your father?" says Doakes. "You want to talk about it?" "About what? That my life is one tragic mistake?" Doakes tries to comfort Dexter by saying, "We've all thought about that at one time or another. I know I have." "Did you happen to be stuffing a human leg into a garbage bag at that point?" "You want to make a change, Morgan? Now's the time. All you gotta do is let me out of here. It's over, man." Dexter, not wanting to hear that, rushes the cage and yells, "It is over when I say it is!" It reminds of the pilot episode, when he yells, "Open your eyes and look at what you did!" Doakes tells him it's good for Dexter to let his anger out. Dexter says that since he's "flying without a code," he could "unleash the beast," and Doakes could suffer the consequences. "Morgan, you know that's not the answer." "But it would feel fucking great." "Yeah, but you would hate yourself for the rest of your life." Dexter lies down on the table, feeling defeated, and says that everything Harry taught him was bullshit: "But it's the only way I know how to live." "Turn yourself in," says Doakes quietly. "Rule number one: don't get caught." Doakes tries to talk reason into Dexter by telling him it's only a matter of time until he hurts someone close to him, like Rita or Deb or the kids, "not on purpose, but you can't control that shit that's growing inside of you. It's like a cancer, and in case you haven't noticed, it's spreading." He continues to implore Dexter to "take responsibility" for who he is: "We'll go to the station together. I'll help you." Dexter looks like he's actually taking the advice to heart, and the two men share a long look at each other. Dexter's phone rings, and despite Doakes's request that he not answer it, he takes the phone outside.
