Dexter is late to counseling, as he meets Rita in the Amazing Technicolor Family Therapist's Waiting Room. Seriously, this room looks like the inside of the Simpsons' house. Anyway, Rita's bitchy and cold, but for different reasons than usual. Dex gets a call from work (supposedly) but Rita manages to stop him cold by just confessing to kissing Elliott. I love how Rita can manage to make confessing an infidelity into a shrewish ploy to nag Dexter into not going to work. Hilariously, Dexter does her one better, using the occasion of this shocking confession to get the heck up out of there.

Cut to a closeup of Hipster Derrick, dead as a doornail on the floor of his home. Close observation seems to place the cause of death as Getting His Face Bashed the Fuck In. While LaGuerta interviews a neighbor, and Dexter takes photos, Masuka wormily pokes around Dexter, asking about "lunch-slash-therapy with Rita." Dex tells him to quit reading his desk calendar and tries to change the subject, but Masuka finally gathers his stones and blurts that he saw Rita kissing the neighbor. Dexter, of course, knows, and Masuka's relieved. Meanwhile, the neighbor gives LaGuerta Hipster Derrick's name: Kyle Butler. Dexter's super-keen serial-killer ears pick that one up from across the room. DVO states the obvious (Arthur's in town and looking for him), then lays on the guilt about another innocent man dead because of him.

Christine Hill's Apartment of Cop-Fucking and Crazed Pacing. Angel and Deb sift through boxes of shoes before they happen upon something far more useful: postcards to Christine from cities that match the Trinity killings, all signed "Love, Daddy." "It still doesn't give us Trinity," Angel cautions. "No," says Deb, "but it gives us something to make the bitch talk."

Closeup on an apartment door that says "K. Butler" on the front bell. Someone rings it and waits for the poorly-named sap to step outside to look around. That's when a syringe gets plunged into his neck -- yes, this is Dexter getting the jump on him. Has Dex decided to just cut out the middle man and start killing these innocent bystanders before Arthur can? YOU'RE SO STUPID. Actually, no, Dexter just wants to knock this Kyle out so he can lie in wait for Arthur. Okay, let's hear it for the first sensible thing Dexter's done all week. (Yes, I just described injecting a man with a paralytic and squatting in his house to better kill a man as "sensible.") Oh, and in case you were wondering and/or a moron, DVO lays out the whole plan for us in delicious redundo-vision.
