Izzie's patient is Vinnie Van Lowe from Veronica Mars, and he's acting like the few scratches he's got are the most painful lacerations that ever lacerated. He jackassedly asks Izzie, who's cleaning his wounds, if she knows what she's doing, because she's really hurting him. Izzie: "Know what REALLY hurts? Gunshot wounds." Heh. "Brad" says he didn't get shot because he's such a quick thinker (here he calls her "sweetheart," which...shut up, Brad) that when he saw the shooter, he knew what was coming and dove right through the window. Two of Brad's employees roll by, crying into their actual gunshot wounds, and Brad calls out, "Hey Chaz, Larry. No offense, but you guys gotta think quicker on your feet!" Oh my God. Izzie reminds him that the people he just taunted have serious gunshot wounds. Brad can't shut up about how awesome he is. "Really helps that I'm an athlete. When I saw Petey with that gun? I was like, cat quick! Those guys? Not so smart." Izzie takes a wild guess that Petey must have been looking for Brad.
Alex asks Mere if she's seen any enema kits. Mere asks him why he's looking for enema kits when they have thirteen GSWs. Alex: "Trapped upstairs with the Gyno-Beast on the Uterus Parade." Oh, man. That is officially my favorite sentence ever. Mere says Addison can't keep him forever. Alex says she can, too, and swears she's ruined vaginas for him.
Webber reports to Burke that there are two dead and fourteen injured on Petey's little shooting spree, and since he got away, there could be more incoming. Burke offers to stay and send Bailey in his place; Webber tells him no, he's their only cardio-thoracic transplant specialist, so he should go get that heart. Alex overhears this, and his eyes light up as Burke's walking out the door. Cristina tells him to forget it -- she already asked. Alex runs after Burke anyway. Cristina follows him, yelling, "It's not gonna happen!" We'll see. Alex catches up with Burke as he's getting into the helicopter, and asks if he can go too. Cristina yells over the helicopter noise that she asked first. Burke gives Cristina a long look, then says, "Let's go, Karev." Cristina gapes at them as Alex boards the helicopter, all, "See ya, Yang!" Damn, that was cold. Inside the helicopter, Alex asks who the lucky patient is. Burke stares out at Cristina and answers, "Denny Duquette." (Duh.) Cristina stands on the helipad and watches as they take off, first defeated, then angry. She stomps back into the hospital, aaaaand...credits.
