Kem has gleaned that Pertussis Mom has another kid at home with her sick mother, but Granny Tussis won't come into the hospital because she doesn't trust American doctors. "What if we go there?" she asks. Carter shrugs, "This is America. We don't make house calls." He sounds like a complete and utter asshole when he says it -- all condescending and amused, as if Gamma didn't have a doctor on speed dial who leapt to her aid at the manse, for fear of being killed by the force of her withering, frosty patrician glare. Kem drops her eyes, and then stares pointedly at Carter, a hint of a smile on her face, a trace of a pout, and a faint hue of disappointment. She holds it long enough to drive Carter crazy, and he tells Gallant to make a run to the woman's house. Is he allowed to do that? For someone who can't seem to stop gushing about the insane resources this country, Kem's suddenly awfully comfortable abusing them.

Carter gets called to Morgan's bedside; his lung collapsed. Pratt frantically tries to get a chest tube tray prepared. "I knew this was gonna happen," he snipes. The guy starts to regain consciousness. Oh, people, come on, knock him out! Ack! Aren't they cutting into him? This is why I would hate being in the hospital. I don't want to wake up until I've been home for a WEEK. Pratt frustratedly hands off the suturing to Neela, and storms away over Carter's protests. "This guy's good and I've got other patients," he hisses.

Outside the exam room, Pratt bangs his fists against the wall and then touches his forehead to it, defeated. We fade to black craving a Pop-Tart. What? Aren't you?

As a puzzled Carter seeks out Kem, the rig pulls up in the ambulance bay, and a pissed-off paramedic gets out. Kem follows, cradling a squalling infant wrapped in a thick blanket. "The paramedics needed a translator," she insists. Carter can't believe what he's seeing. "You took her?" he sputters. He glares at Kem as they hurry Granny Tussis inside.

Trauma Green. Carter's still royally pissed that Kem left. Kem reports that almost the entire building is sick, which just makes Carter angrier that she exposed herself to all those toxins. Kem looks ashamed for a second -- hey, if I looked that bony, I'd forget I was pregnant, too -- and then defiantly reminds him that pertussis isn't a risk to her pregnancy. Carter points out that any other germs could've been floating around, including TB, and he's generally just irritated with her for going. Kem points out that she's been living and working in the Congo, and that the germs there aren't exactly benign. As Kem flounces out, per Carter's orders, to go talk to Pertussis Mom, Chuny cracks, "You sure you two aren't married?" Granny Tussis is septic and isn't doing too well, by the way, but nobody cares because we're not going to see her nipples.
