Back with modern Dexter, who is voice-overing once again that "preparation is vital. No detail can be overlooked." And as he marks up a blueprint of the place where he clearly plans to kill Jamie Jaworski, he says, "And the ritual is intoxicating." He looks like a kid who's putting together his first Lego set.

At the spot, now. It's an unfinished room with exposed beams. Dex is duct-taping trash bags to the walls to prevent noticeable blood spatter. He spreads rubber sheets over a table. He stretches out some Saran Wrap. "Necessary tools of the trade." You're the expert, dude. I always like to think that because I watch so much CSI, I could totally pull off the perfect murder, but I would never think of all that stuff.

Now it's time for lunch with Deb, who wants to talk about the chopped-up bodies. Dexter, good brother that he is, explains his theory that the killer is trying to get it right, and is looking for some sort of inspiration. Deb seems appreciative for the input, but quickly changes the topic to Dexter's date with Rita. He says it was great, and that she should try it. She wants to wait until she's in homicide, then worry about all that. Bringing it back to the case, she asks Dexter about "cell crystallization," which she overheard the coroner mention with regards to the "headless chick." She mentions how the pieces of the body were "cold, like, meat-packing cold." "My God, why didn't I think of that," Dexter thinks. "Dex?" "Sorry, I was thinking...that makes sense. Cold...slows the flow of blood." After Deb mentions how everyone thinks she can only close a case on her back (heh), Dexter semi-whispers, "Refrigerated truck. Cold to slow the blood flow, mobile so he can get rid of the garbage. Probably a stolen one." Good call! Deb thinks so too. Get on it, Morgan!
