Trauma room. Peter asks for more suction as the machines bleep ominously. Peter calls for a certain type of suture and, long story short, manages a difficult tie-off called the Kennedy maneuver while nurses hang more units of blood and auto-transfuse Laura as well. Luka looks on sternly as Mark compliments Peter on his technique and goes next door to deal with a seizure, and Luka asks if they should spin another crit; Peter shoots him a look and shrugs, "Yeah. Fine." Cleo pulls Luka away -- with her bloody glove on his ungowned arm, might I add -- and urges him to come with her to talk to Laura's Mom, but just then Laura's pressure crashes. Peter doesn't get it -- her chest is dry, he just stopped the bleeding there. Luka says to check the belly again, she must still be bleeding somewhere. Cleo checks the ultrasound and confirms Luka's diagnosis, saying Laura's "got a bellyful of blood." Luka says something about popping a capsule, and Peter grumbles that they should have checked the belly all along, then begins shouting marching orders to get Laura up to the OR. As they pull Laura out of the trauma room towards the elevators, Laura's Mom jumps up and asks what's going on. Luka tells her they're taking Laura to surgery and points LM out to Peter, who tells her to come with them. They board the elevator. Peter tells Luka he's done enough and to step off. Luka pleads, "I want to stay with her, she's my patient," and Peter waves him off and says, more gently than he usually would, "Not anymore." The doors close, and Luka sort of gesticulates at them in frustration with his bloody gloves. Cleo, right behind him, grabs his arm again with her bloody glove and suggests that he go home and get some sleep. "You think I'm going to sleep?" Luka snorts, and he turns and gallops up the stairs, taking them two at a time and ignoring Cleo as she calls after him.
