Dexter's in his office, forwarding through Lundy's last tape. He's looking for a description of Trinity while his voice-over is telling us things we already know. While we get a sepia-tinted flashback of When Trinity Met Lundy, Dexter listens to Lundy's description. Afterwards, he heads out into the commotion in the bullpen: They've got word of a motel shooting, the victim matching Johnny Rose's description. The whole team heads out, but Masuka tells Dexter to hang back, since he can't work the case anyway. Though he fervently hopes Deb "is finally gonna get some justice." Yes, her long day-and-a-half search for closure has finally ended.
At the crime scene, Masuka notes the "karma" inherent on Rose's dead body, and counts three bullet holes. The team -- Quinn, Angel, LaGuerta -- assumes Nikki did it, per Angel's planted story. They get a call that Nikki's out in a nearby alley. Indeed she is, pacing and screaming and twitching and holding a gun. Angel and LaGuerta don Kevlar vests and try to reason with her. Yeah, reasoning with Maim-y Winehouse over there is maybe not the best idea. (Yes, I know the VMs didn't maim anybody, but let me have my fun.) Angel and LaGuerta gingerly close in on her, while Nikki continues to rant to a not-present Johnny about everything he promised her, all the lies he told, et cetera. "YOU PIECE OF SHIT!" she screams, just before Quinn nails her in the back with the taser. Tasers: Is there any unstable, gun-wielding crack whore they can't disable?
Back at Dexter's, Deb gets the call from Quinn that Rose is dead and Wald is in custody. Quinn, because he's a good cop but not a smart person, is psyched as he tells Deb about how they nailed them and how this should provide her with some peace of mind. Deb's all, "Oh. Totally," but Quinn's too busy about "taking this skank down to booking" to notice.
In the hallway, LaGuerta laments to Angel about all the killings, over what appears to be one junkie promising another junkie a trip to Bermuda. "Hell hath no fury like a meth addict scorned," Angel notes, hopefully retiring that cliché for a few hundred years. And like a rain cloud over an otherwise productive day, here comes Matthews to call LaGuerta into her office. He gives her props for closing the case, though she tries to deflect it to Angel and his awesome newspaper story idea. Matthews says that's all well and good, but they can't risk the courtroom sideshow that could ensue every time a defense attorney brings their relationship up in court. Which is why Matthews is transferring Angel out of homicide. LaGuerta flips on this "bullshit" -- they followed protocol and everything! Matthews is all, "Hey! I'm giving him a promotion too! No worries." He's a dick. Even if it's maybe the right call. He tells Maria to have the papers on his desk by Monday. Matthews crosses Angel's path on the way out the office, and Angel can tell by the look on LaGuerta's face that it's not good.
