Upstairs, Benton trots off the elevator and is hailed by Joanie, who shouts, "Uncle Peter?" She wants to talk about her parents, Uncle Peter. They're having problems, Uncle Peter. Are we clear that he's her Uncle Peter? Joanie frets about her mother's deteriorating emotional state, wherein she appears fine one second and then locks herself in the bathroom the next. Benton calls this normal behavior. "No, it's not," she argues. "They fight all the time about her job, about Jesse's room. Dad washed a shirt that had his scent on it, and Mom went nuts!" Joanie implores Benton to confront her, but he insists there's nothing he can do and that time will fix the problem. "It's almost been a year," Joanie breathes tearfully. Benton looks extremely put-out, and practically shudders with relief when his beeper interrupts the conversation. I hope Joanie bills him for forty sets of brake pads.

Peter suits up and heads to trauma one, in which Zombie now lies. He's stunned to learn that she jumped the four storeys while waiting for her consult, and swiftly assumes control of the situation from a blood-soaked Kerry. He orders a chest tube and a milligram of atropine, suspecting a case of pericardiocentesis -- which absolutely would have been my diagnosis, had I ever gone to medical school. Peter commences compressions to revive her flagging pulse, but with blood seeping into her pericardium -- the sac encasing her heart -- it looks bleak. Luka prepares to tell Leona that Zombie is dead, but Peter isn't ready to call it yet because, if he does, he'll have to go pay attention to his niece again, and he's not interested enough in her life. Luka insists that Zombie is moments from death, quietly exiting to find Leona. Abby and Haleh yank Benton's attention back to the patient, who is in asystole -- her heart is fast losing the ability to force blood through her body, and she's all but officially toast. Haleh looks sad. Benton pumps her chest a few more times, then resignedly calls the time of death as 12:17.
