In the doctors' lounge, Mark serves up coffee while Jen complains. Rachel disobeys her curfew, refuses to listen to her mother, and never helps out around the house. "How would you know?" Rachel brats. "You're never there!" Jen exposits for Mark's benefit that she just made partner, and then bitches that she's only working hard so that her ungrateful daughter will have a roof over her head. As a defense for working long hours, I've never bought that argument. It's not like Rachel's portion of the house is roofless pending further paychecks. Mark milquetoasts that there's clearly a lack of communication between mother and child, and proposes a compromise: if Rachel acts more responsibly, Jen will endeavor to spend more time bonding with her daughter. Rachel shouts that Jen is unreasonable and doesn't listen, while Jen complains that, after fourteen years, she's sick and tired of being Rachel's maid. "Tired of being a mother is more like it," Rachel accuses her. "Can you blame me?" Jen gripes. Yes, I can. That's what "pregnancy" means, and that's what "custody" means. Both are choices. Suck it up and stop acting like life took a shit in your underwear drawer. Although I'm also tired of Rachel, which is probably a testament to the actress's skills. She is one whiny teenager. Jen has had enough; she came to fetch her child, and now they have a plane to catch. "What if I'm not going back?" Rachel asks defiantly. Mark sits there uselessly, like the tumor he is. Angrily, Jen points out that she cancelled her entire day to come to Chicago. "Sorry I'm such a pain in the ass!" Rachel screams, storming out in a right snit. She bumps into Haleh. "Dr. Greene, we need you," Haleh says. Sighing, Mark turns and regards Jen briefly. "Remember when she used to flush her crayons down the toilet?" he recalls, tiredly. Jen isn't in the mood for nostalgia. "Seriously, Mark, you've got to help me here." Slumping a bit, Mark promises to be right back, and hightails it after Haleh.
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.
