Once they're outside, Abby asks if Mi-Cha is pretending to be confused or if she really doesn't understand that she just gave birth. Carter doesn't know. Abby reminds him that she can't break confidentiality and tell the mother about the baby. Carter spots Mrs. Pak walking toward them. Can't they tell Mi-Cha that her mother is there, though? At least then she'd stop worrying about getting home before her parents. Carter tells Abby to call his crush in Social Services, as well as Psych. He greets Mrs. Pak.
Neela finds a paramedic wheeling in a Girl Scout with a head bandage. The paramedic gives the bullet, which includes the nugget that the patient is forty-three years old. Uh, no she's not. It takes Neela a minute to catch on. Shane West greets another incoming patient, who is described as a twenty-eight-year-old male with a penetrating injury, except she's a twelve-year-old girl on a cell phone. Shane West catches on to the discrepancy right away. Malarkey gets the next fake patient and asks what's going on. The inspector or whatever marches in and asks Malarkey if he's the incident commander. God, no. She explains that this is a drill, and starts her stopwatch. Malarkey yells for Dr. Lewis.
The detective approaches Sam and says that he got some background on Louise. She's been a widow for five or six years, and has no children or other family. Sam thanks him and turns to leave. The detective says that the rapist uses the same MO, and has attacked four women in the last five weeks by posing as a pizza guy who is confused about the apartment number. The detective sighs and advises Sam not to open her door to anyone she doesn't know. Sam asks if the other victims are going to be okay. The detective says that the guy rapes them, but also beats them severely; one died and the other three are in bad shape. The detective says resignedly that each victim has helped the cops to get closer, and that if Louise dies, they'll just have to wait for the next one.
Pratt wanders the hallways and gets updates on the drill participants, who are all prepubescent Girl Scout types. Two of the girls start complaining that they were told they could stay together, even though Pratt tries to send one of them away. The drill inspector looks on with raised eyebrows.
Susan reminds everyone to call his or her consults, because response times are being tracked as well. She trails off when she realizes that she's talking to herself. Haleh tells Carter that Wendall is there to talk to "the Korean virgin birth girl." Luka asks Frank about Jerry's whereabouts. Jerry has disappeared to avoid the Drill of Annoyance. Luka comments on how crazy the drill is, and Susan agrees. There's a way too long scene between them that seems totally ad-libbed until Shane West walks in, so I think he was late on his entrance. He wants to help a real patient. Chuny runs up and asks Susan if she really wants all the red tags in Trauma One. Susan doesn't. A Paris-type scout (read: bossy and assertive) walks up and introduces herself as Trina. Frank gives Susan the phone because the lab wants to yell at her. Susan tucks her still-awesome hair behind one ear and heaves a sigh.
