Mark scrubs in at the trauma room, where he joins Benton in working on a pedestrian hit by a car. Benton didn't detect any signs of head trauma. The paramedic clarifies that the girl was, in fact, already lying in the middle of the road when the car struck her, so it's possible she took more than one hit. Mark checks her pupils and deems them reactive, as Haleh relays that the girl has a weak pulse. Benton notes a contusion in her upper left quadrant, then exclaims that she's got a severed umbilical cord hanging from her body, no sign of a baby, and an undelivered placenta. Mark will try to extract it, but wants someone from obstetrics to come down as backup. Haleh holds up the girl's foot. "She's missing a shoelace," she says dramatically, certain she's located The Womb That Birthed The Baby That, So Far, Hasn't Brought The ER Together As Promised.
Abby stares into a fish net and wonders whether they can resuscitate a fish. Carter doubts this. "Think we should flush him?" Abby asks playfully. "Think Luka will miss him?" Carter snorts. "Maybe he'll think one of the other fish ate him," Abby grins, shoving the net toward Carter. He flirtatiously bats it away, but clearly wants her to snare him with it. She makes him take it, and he then dumps the supposedly expired fish back into the tank. It sinks. Not so dead. As she wipes down the tank's glass, Abby babbles that she was bad with creatures and used to paint her pet turtle with nail polish, but Carter is anxious to leave and isn't listening. They're cute together, but the madcap-adventure plot feels really forced. Carter is anxious to leave. "I just have to wipe the place down for prints," Abby sasses. Hunched over, ready to pick up the new fish tank, Abby freezes when she hears the door buzzer. Peeved, Carter hangs his head while Abby sneaks over to check the peephole; she sees two impatient-looking cops staring back at her.
