Jimmy shows Beck some corpse photos of John "The Hunter" Doe, saying that they found his body with his neck broken. Hawkins adds that it wasn't hard to finger Sarah Mason as the murderer. "What makes you think that?" Beck snaps. "Well, look at his neck -- it's snapped clean," Hawkins points out. Isn't that what you did to one of the SS in the Situation-mobile? Oh. Right, they probably figured it was Chavez, since Beck realized (belatedly) that he was BlackOps. Beck asks whether they ran prints and DNA. "Well," Jimmy laughs, "the, uh, CSI department has been a little busy lately." Great. I watched Superbad last night and all I can think of now is, "Well, if only Sarah Mason had been a guy and ejaculated on the guy she killed, then we'd have a positive ID." Because, really? How different is Jimmy from Officers Slater and Michaels? Beck silences all of this with A Look. Hawkins glances at Jimmy and tells Beck that they've been offline for a while. Beck tells them to run it now and see what turns up. "You know, when you do," says Hawkins, pulling out an ammo clip in a baggie. "There's another set of prints you should run as well." He hands the baggie over. "Think you could lift a set of prints from that, Jimmy?" Hawkins asks. Jimmy looks challenged. "Uh, sure, I'll give it a shot," he mutters. Jimmy leaves, making a note to look up "how to lift fingerprints" in Wikipedia. Beck asks whose prints are on the clip. Hawkins tells him that they are Sarah Mason's: "We exchanged fire." Yeah, fire and bodily fluids! "Almost had her cornered, but then she slipped away. Left that clip behind." Beck wonders what Sarah Mason's prints can tell him that her dossier doesn't already. Hawkins shrugs that they'll find out.
