At the crime scene, Dexter photographs the victim (poor dead Sandwich Guy) as DVO notes (he's still on probation, but this should be noted) that Trinity, having completed his cycle, will have his guard down and be easier to catch. Dexter's trying not to give too much useful information to Masuka and Quinn -- he's trying to get Trinity dead, not arrested. The best he offers them is that the perp was taller than the victim, given the spatter pattern. "Duh!" scoffs Masuka. Dex then mentally notes the victim's right arm was moved to point to a spot on the wall. He tries to be smooth and collect the dirt smudge particles from off the wall, but Masuka catches him and wants all the non-blood evidence he can get. Miami Metro: 1, Dexter: 0.
Back at the corpse, Masuka notes the bloody pattern on his forehead suggests a framing hammer. DVO: "Duh!" Okay, DVO, that was a good one. Dex asks Masuka how he knows so much about hammers. Masuka: "There's not a tool I haven't played with, my friend." Ew, Vince. Ew.
Meanwhile Trinity's out in his garage, whistling that same churchy song and cleaning off his killin' hammer. Really cleaning it, too, with bleach and everything. You could eat someone's brains off of that thing.
At the station, Deb watches Angel interrogate Nikki on the monitor. Nikki denies being at the hotel the night Lundy and Deb were shot, and Deb obviously thinks the "fucking junkie whore" is lying. Quinn shuts the TV off, telling Deb she shouldn't be watching. Nikki's gonna get sent away for a long time anyway, but they just have no way to pin the Lundy killing on her. Clearly, this is not good enough for Deb, but what can she do?
Angel, similarly frustrated, vents to LaGuerta about not getting Nikki to confess. LaGuerta says the brass wants the case kicked to County anyway, much as it frustrates all of them to leave Deb and Lundy's attack unsolved. Angel notes that he hasn't told anyone about his transfer yet (Maria hasn't done the paperwork either). He tries to put a rosy spin on it -- better hours and pay on the Fraud beat, plus he won't get shot at from behind his desk. LaGuerta laments that he hates sitting behind a desk, but Angel counters that he loves being with her. And she shouldn't beat herself up about telling Matthews about them. Just once, I want a show about a cop who LOVES his desk job. It can be on after the show about the lawyer who always takes the plea bargain.
