Debra meets with Captain Matthews, who greets her warmly. I'd forgotten that he's supposed to be this old friend of Harry's, looking out for Deb. But it's a good time to remember that, because that's why Deb's here. As soon as Deb starts recounting the specifics of the Moser case, Matthews knows which one she's talking about. And in all likelihood, he knows why Deb's asking. But he lets her lay it out. He confirms that Dexter's mom died in that shipping container, that Harry adopted Dexter thereafter, but that Brian was deemed too damaged. Deb assesses that statement and gives it a "No fucking shit," given the whole Ice Truck Killer thing. Quinn keeps blowing up Deb's phone, but she needs to hear this. Matthews defends Harry keeping this info from her and Dexter, to protect them. Deb's like, "Point taken, sir, but I know now, and it's kind of completely wrecking the fragile ice castle that is my life." She wants to know what to do with this, and Matthews tells her to keep it to herself. Pretty much what Dexter did, though he's felt guilty about it ever since. Deb, having gotten her answer, takes Quinn's call.

Arthur's on the computer, in his garage, looking up listings for "Dexter Morgan" online. He finds an address for "D. Morgan" on Palm Terrace in Miami. As a reward for this successful bit of research, he allows himself an evil chuckle.

That night, Dexter stares apprehensively out through the bedroom blinds as Rita walks in. He wants to go to the Keys tomorrow, for their honeymoon. Rita's less enthused about this idea after Dexter's little adventure in lock-up, but Dexter's feeling the urgency to go. What with Arthur on the prowl and all. Of course, he doesn't say that to Rita. She's still reticent, so he apologizes, fairly sincerely. In particular, he apologizes for becoming the kind of husband Paul was to her. Rita disabuses him of his notion, saying that when Paul would get picked up by the cops, she was relieved. But Dexter's the biggest part of her life, and the kids. She's just upset at the idea of losing him. "You have your demons," she tells him, sweetly, "I accept that. Because I know you don't have to be a slave to them." Dexter really hears this, even if he doesn't entirely believe it. She tells him again that she believes he can conquer whatever darkness he has inside him. "I want to be that man," he says, grabbing Rita close to him. He again asks her to fly to the Keys tomorrow morning; he wants to meet her there. Dex proceeds to follow up this request with some lovin'.
