Back home, Dexter is being tormented by Harry, who keeps reminding him that Zoe knows where he lives now. Dexter at first wants to back off, give her what she wants. But Harry says that's out of the question, if he wants to keep his family safe. Sure, it'll be impossible to sneak up on her now, but Dexter said he wanted a challenge. "You banged the beehive." Dexter interrupts this conversation with himself to play his voice messages. It's from Lundy, looking for Deb. He starts to talk about how he ran into this guy today, but Dex cuts the message short. Harry resumes, impressed as ever by Zoe's work. "Makes you wonder why someone like her ever got married and had kids in the first place." Subtle, Harry. Dexter begins to protest but his mind wanders, because "someone like her" also needs to be in control. And now that she knows she is, Dexter can use that. "She won't see me coming."
The next day, at the office, Dexter calls up the records clerk (Zoe's pal, it seems, and I'm getting a very Terri Scheuster/Howard Bamboo vibe off of those two now that I see him) and very unsubtly requests to be sent the Darius Rey file. For...you know...the Vacation Murders case. He clunkily asks him to send said file simply to "Forensics." After he hangs up on poor suspicious Howard, Dex voices over that the beehive has once again been banged. Not. Like. That. Ow.
Next? The Further Misadventures of the Couple I'd Like to Christen "Anguerta" (Or Possibly "LagAngel"). LaGuerta lassos Dexter into her office and pretty much gives the mirror image version of his scene with Angel. She really needs someone to talk to. Dexter is incredibly uncomfortable. She doesn't notice and proceeds to air her brain out and babble about how Angel doesn't understand department politics and how it could all blow up in their faces if they take their chances and keep secret. Dexter then delivers one complete sentence that's more about him than anything else ("I never leave anything to chance"). LaGuerta gleans from that what she wants to glean. Dexter leaves, bewildered. LaGuerta thinks they just had a real good talk. (She also notes that, given the "good" "advice" he just gave her, marriage is agreeing with him. Har.)
