Ambulance bay. A guy in a blue HazMat suit comes off the school bus and pronounces it "okay." The fire chief tells Mark that the bus is fine: "No carbon monoxide, no flammables." "The kids smelled something?" Mark leads. The chief replies, "Maybe, but it's gone now. Probably just mass hysteria." Mark and the Chief head over to Dr. Dave and Luka, standing near the ass end of the bus. Dr. Dave seems skeptical, so the Chief elaborates: "Kids smell nail polish remover. Pretty soon, everybody thinks they're sick." Luka asks whether they need to scrub the kids down, but the Chief says it's not necessary: "No one's contaminated." Mark suggests that they split the kids up, and approaches the little gang, asking, "Who had vomiting?" A couple of kids put up their hands. Mark directs a dark-haired, ponytailed girl named Emily toward Luka. He asks if she's still nauseated just as the camera lights upon Dr. Dave, asking a couple of girls whether they experienced a stiff neck or double vision. One says no, and then coos, "Are you really a doctor?" "When I'm not out fighting crime," Dr. Dave flirts. The girls giggle. Okay, there's barely legal, and then there's nowhere near legal, so put it away before you hurt yourself, there, Dave. Pan over to the trio of punks, leaning against the hood of a cop car and smoking. Mark beckons them inside, but Punk #2 says that they like it outside; Punk #3 agrees that "fresh air is good for you." Mark sternly tells them to put out the cigarette and go inside. Punk #1 -- who totally looks like the love child of Elijah Wood and Eminem -- sasses, "You got a spare ashtray?" Save it, half-pint.

Trauma room. It doesn't look good for Mrs. Howard. Kenny and Ms. Cop are back at the end of the bed. A guy -- presumably an Internal Affairs investigator -- comes in and asks Ms. Cop (hereafter Officer Kimball) whether she discharged her weapon. She nods, and Det. IA directs her down the hall toward another detective, telling Kenny to stay with him. Det. IA asks for the names of the treating physicians. Weaver gives her name and, when Benton ignores Det. IA, his as well. Det. IA asks whether they witnessed the shooting; Weaver says they both did, and then confirms the spelling of Benton's name. Det. IA asks, "Is she going to make it?" "Not if you don't let us do our jobs," Benton snaps. "Let me know if she expires," says an unmoved Det. IA, before leaving. Kenny stays behind, transfixed, his eyes flicking between Mrs. Howard's face and Benton's. After a moment, Kenny follows Det. IA out of the room.
