Arthur strides back to the parking garage with a deposit bag full of cash he just took out. Planning for disaster, Art? He should be -- Dexter rounds the back of a van and plunges a syringe into his neck. Sleepy time for the not-so-gentle giant. Dex hauls him into the back of the van and checks out the envelope. Seems Arthur closed out his checking and savings accounts. Dexter's face lights up as he realizes that Arthur's already done the work of making it look like he skipped town, so when the cops come looking for him as the real Trinity killer, it'll look like he left town rather than ended up in Dexter's six trash bags. "Luck is finally working with me."

Let's chalk it up to Dexter's pathology and social awkwardness that he doesn't recognize tempting fate when he blatantly does it, because no sooner are those words out of his mouth than he spots Sideswipey O'Tattleface next to his car, talking to the cops. "Seriously? Fuck!" hisses Dexter. Still savvy (...for the moment), Dexter grabs Arthur's wallet, puts it in the envelope with the cash, and hides it above a light fixture. Arthur himself doesn't stash so easily elsewhere, so he's going to have to bite the bullet and defuse the situation with Sideswipey before he can proceed. Unfortunately, Sideswipey isn't interested in being placated, and he's really not interested in Dexter flashing his laminate around and trying to play the brotherhood-in-blue thing. Unfortunately for Dexter, these sheriff's department officers are also not impressed. Dexter tries to more overtly ask for a pass, at which point Sideswipey pulls out his camera phone to record the corruption. At which point Dexter loses his shit. He grabs the phone and smashes it on the ground, at which point the officers throw him down and arrest him. So Arthur's gonna have to cool his heels in the van for a while longer.

Elsewhere, Deb and Valerie hit up a semi-distant neighborhood, with Val regaling an uninterested Deb with tales of how great Harry was. They arrive at the house Val says belonged to Harry's C.I. on the side. And that's when Deb's jaw hits the ground. "It fucking can't be," she gasps. Val just keeps right on yakking about the porch or some such awfulness, but Deb looks like she might pass out. "I've been here before," she says, before we flash back to the Ice Truck Killer, a.k.a. Brian Moser, a.k.a. Dexter's brother's kidnapping her and keeping her here, in this house, preparing to kill her. When Deb says Brian's name, Val sparks recognition. "That was her name," she exclaims, "Laura Moser! She had two little boys." Deb gets even more gobsmacked and wonders aloud what the shit her dad was involved in.
