Nadia calls Quinn and says her car won't start, so could he give her a ride home tonight? I feel like I'm going to have to ration my lines about this plotline, given that I'm tired of it already.
LaGuerta closes the blinds in her office HILARIOUSLY furtively before opening up a box of evidence (I see, this is why she called the FBI office); after lingering with a fond look over a photo of Doakes, she opens up the blood-slide case and finds -- you'll never believe this -- blood slides! She holds one side by side with the one from the church and looks thrilled, but... would any blood slide appear that different to the naked eye? I'm not sure why this is such a big discovery now; wasn't she already there?
Okay, so Jamie seems to be staying in the apartment with Harrison. Does she have time to do this 24/7? Again, more importantly, what's the cover story, and how long can it go on? In cuter news, Harrison is talking; in news that Dexter finds less cute, Greene appears and makes it clear with a few pointed words and sloppy kisses for Jamie that he did not at all mean what he told Dexter, as DVO notes: "He's not going to quit -- unless I stop him." Again, I'm not sure this fits into Harry's code, but it's not like that hasn't been ditched in the past when it's proved too inconvenient to abide by. Still, Dexter, you're going to kill the guy who's got a video on his computer naming you as his sworn enemy? Maybe it's a good idea that Harrison get used to not having you around.
In Quinn's car, the most interesting thing is that Nadia the Russian stripper knows the word "ploy." Bad flirting ensues, and although Quinn thought she might be freer with her information, all she wants is continued rides to and from work for the next few days. Well, Quinn's probably a better chauffeur than he is a cop, at least.
Deb is pan-frying some meat as she notes that Dexter is awfully quiet, and asks if there's anything she can do. Dexter asks if she has any A-1, which Deb hilariously takes as another shitty review in the Zagat Guide known as Dexter, but as she deflatedly heads to the refrigerator, Dexter pulls out a needle and injects her food with something as DVO intones, "Just enough for a good night's sleep." God, Dexter, some melatonin in her beer would have been a little less dramatic.
Greene arrives home and warily checks around corners, like, if he really is afraid of Dexter I'd think he could have walked a more conciliatory line earlier. As we all know, Dexter certainly knows how to appear out of nowhere and pull off an injection, and just like that, Greene is down to the floor. But Dexter sees a drop of blood emerge from the tiny puncture wound, and gets A Look on his face, which is maybe good news for Greene, since his situation certainly can't get any worse.
