Later, everyone is asleep except for Dexter. He's thinking about the blood. Harrison wakes up. Dexter puts him in his carrier and leaves. He investigates the truck and notices traces of blood all over the inside of the door. He thinks, because of some small hand prints, that it was a woman who died. He seems satisfied, having done a little of what he does best. Suddenly Harry is there telling him that he should be concentrating on the kids like he said he would. I watched this with Joe Reid and he made a severe yet salient point -- maybe Harry has come to the end of his usefulness as a narrative device. Does Dexter still need this relationship with him? Hasn't so much of his evolution been about moving away from the code? Dexter tells Harry that he has to take care of his own needs too, but Harry says that the kids are not just his responsibility but also his salvation.
Back inside, Dexter taps into the moving van web site and finds information for the last renter of the truck, Boyd Fowler. Dexter finds out that Boyd works for the Department of Sanitation and picks up dead animals. That must be where the blood came from. Dexter does a test- it was human blood.
The next day, Dexter is waiting by a dead raccoon on the road. Boyd arrives in an official truck. Dexter had called in the dead raccoon because he was driving by and it creeped him out. He says that Boyd must be used to seeing dead things, but Boyd says you never get used to it. Dexter mentions that he's moving and doesn't moving suck, but Boyd offers that he has lived in the same house for 20 years. "Why the moving van?" Dexter wonders, though that's not nearly as much wondering as he would have to do if this guy Boyd weren't answering every single one of Dexter's odd questions. Makes finding the next person you're going to kill a lot easier, I'd imagine. Boyd says hi to the bandit then points out that the raccoon was clearly killed, then dropped on the road. Dexter VO's that Boyd is CSI-ing him. You could consider it Dextering too, though Boyd hasn't bludgeoned or stabbed anyone. Yet. Boyd throws the raccoon in the back and takes off. Dexter notes that he's odd, but reckons the "best and brightest" don't get into the business of dead animal pick-up. Well, that's judgmental.
