Carter is doing his "swan" as Lily assists. She tells him that the "blood's bright red." Carter crows, "I knew it! This guy's got a whole in his heart, leaking oxygenated blood to the right side." Luka storms in to demand to know what Carter's doing, and to berate him for not sending the patient, as instructed, to the cath lab. Carter tells Luka he's doing a swan, and Luka says, "We don't do swans in the ER!" Haleh mutters, "I told him that." Luka says that the patient should be upstairs getting an angioplasty. Carter says that the patient would have died in the cath lab, and shows Luka the bright red blood. Luka's like, "Shit," but asks, "What about his M.I.?" Carter dismissively says that they can bypass the patient when they mend the rupture. Luka looks annoyed, but clearly isn't in much of a position to argue, so confines himself to admonishing, "We're supposed to work together. Next time, you tell me what you're doing." Carter's like, "Whatever."

Dr. Dave stitches up the facial laceration of The Boy Who Could Permanently Scar His Own Child. The Boy is evidently in a great deal of pain and begs, "Can't you give me something?" Dr. Dave breezily says, "Just a couple more stitches, and then they're taking you to jail." Weaver watches for a moment, but when the Boy yells, "Ow! You're hurting me, dammit," she crutches in and tells Dr. Dave to give the Boy more lidocaine. Dr. Dave says, "I did an infraorbital block," and Weaver says, "You must have missed the nerve. Infiltrate locally." Dr. Dave pauses, and then says that if he does, it'll distort the wound edges. Weaver tells him again, "Infiltrate subcutaneously or I'm going to take over." Dr. Dave considers for a moment, then says, "Fine. You do it."

Oh, lord. Chen pages Romano to the PICU, where she and Mrs. Latimer are sitting beside Kenny's bed. She tells him that there is no consult, but that she's started a petition to start doing metabolic screens at County, and that she'd like him to sign it. Because Mrs. Latimer is there staring him down, he signs, but he doesn't look happy about it. I'm sorry that Kenny had a seizure, but you know what? I think we GET IT.
