Meanwhile, in a plot across town, Calleigh's hopping out of her Humvee and asking Hagen, "Just you and me?" "I thought I'd start walking my own lonely road, since it appears to work so well with the chicks," Hagen shoots back. Oh, he does not either. He gives Calleigh a mock-outraged expression and pouts, "You sound disappointed." I would not be disappointed if I were to spend one-on-one time with Hagen; his anti-Horatio attitude was refreshingly different, and he's pretty easy on the eyes. Anyway, Hagen gives Calleigh the bullet: "Joe Family Man runs to the convenience store to get milk. He gets popped. No ID, no wallet. I figure robbery." Calleigh notes the up-close entrance wound and comments on how it seems kind of personal for a robbery. Hagen thought so too, so: "I had patrol canvass for a wallet. Found it over there in the trash. Cash, credit cards..." Calleigh finds a bullet in the pristine back seat of the SUV; she notes that she might be able to get a print off it, on account of it not currently being lodged inside the dead guy. Hagen doubts her: "Heat from the primer burns the prints off." Calleigh replies, "That's true, except this one is unspent, so it didn't go through the barrel. I guess the primer probably malfunctioned because of humidity, so when the firing pin hit it -- nothing. It was a dud." During the back-and-forth with these two, we see a TMICam shot of the shell being thwacked by a firing pin and starting its long, hot journey to the inside of center of someone else's body, and then we see the same thing happening, only the bullet not going anywhere. I still don't quite get the explanation -- for example, it's not immediately apparent what the primer is, so I don't get how it's burning things or malfunctioning -- but it's sufficiently jargon-y to gull the unwary into believing that this show is more than a typical, predictable cop show. Hagen, who appears to have developed some sort of infatuation with Calleigh in the last four minutes, smiles, "I stand corrected." Calleigh beams back and tells him that's what she likes about him. Aww -- the courtship dance of police department employees, performed in the springtime over rapidly cooling bodies, is a sight to stir the most hardened heart.

Then Calleigh gets a good look at the victim's face in the rearview mirror and gasps. It turns out she knows him. And how, you may ask, does she know him?
