CST starts seizing some more. Elizabeth examines the x-ray and says his lateral neck looks good. Carter asks for more "kerlex" since "he's soaked through these"; he withdraws a length of gauze from under CST's head and, sure enough, it's plenty bloody. They remove his neck brace. He's herniating. Things are beeping. CST is bleeding. Elizabeth is yelling. Everybody was Kung Fu fighting. CST loses a pulse. There are too many traumas on CST, and not enough hands.
Haleh brushes past Lisa into the next trauma room, where Luka is slowly telling the detective, "I didn't see him coming." The detective asks what happened after CST hit him from behind, and Luka says, "I went down." The detective asks whether CST took his wallet, and Luka says he did. "And you felt your life was in danger," the detective leads him. "Mine and hers," Luka agrees, briefly looking at Lisa. The detective asks whether CST threatened to hurt him, and Luka says, "I'm not sure." The detective -- clearly trying to make a case for self-defense -- asks, "Did he say, 'Gimme your money or I'll kill you'? Anything like that?" Luka wearily says, "He had a pipe. He was going after Abby." The detective pauses a moment and asks Lisa, "And you can corroborate this?" She says she can. The detective says, "Let's wait and see what happens. Seems pretty clear it was self-defense. Shouldn't be a problem, doc." Lisa looks at Luka, who can't seem to meet her eye. Haleh crosses back into CST's trauma room; as the door swings, the cacophony of beeping machines gets louder, and then muted, again. Luka resumes his post at the door. Lisa stands with her back to him, and her arms crossed.
In CST's trauma room, Elizabeth saws his head open. She can't find the source of the bleeding. CST loses his rhythm, then gets it back. Elizabeth orders a drug that Carter says will induce a coma; Elizabeth says, "It's either that or watch him die."
Lisa brings Finch to suture Luka's head. He tells her his injury is superficial. Finch asks whether he lost consciousness, and when he doesn't answer, Lisa says, "For a moment, yeah." Finch gently asks to fix him up, and he turns partway toward them, without looking at either of them, and shrugs Finch off with a curt "no." She asks whether he has a headache, and he yells, "Leave me alone!" Finch and Lisa stare at him, stung, and he lowers his voice again to assure them (unconvincingly) that he's fine. Lisa sucks her cheeks.
Peter strolls past a mentoring poster (a sign of more Jesse to come?) and enters Romano's office. Romano looks as if he's been expecting to see him, and gestures for Benton to enter. Not pictured: the four shots of Wild Turkey Benton needed to knock back so that his pride wouldn't be such a daunting lump for him to swallow. Also not pictured: the countless lawyers of the greater Chicago area who would have been delighted to represent Benton in a wrongful dismissal case if only Benton had picked up a damn phone.
