"My chest hurts!" Laura screeches. I know she just got hit by a car, but damn, that girl has a really annoying voice. "What is it?" Laura's Mom asks, and Luka says he's worried that Laura is bleeding internally. LM starts hyperventilating and wondering where's the ambulance, and Luka tells her it'll come soon, but LM doesn't want to wait and whimpers, "Let's, let's drive her!" Luka doesn't seem to think much of this idea, but he sits up straight and looks around until he spots a guy loading stuff into the back of a big van, and he runs over to the guy and introduces himself and asks the guy if he can make room for Laura in the back. "You want to put her in the van?" the guy asks incredulously, and Luka tells him Laura has to get to the hospital right away, "it's urgent," so the guy agrees, and they head back over to where Laura's lying.

Elizabeth tells Mark about walking in to find Holling with her mother. Mark finds it funny and starts laughing, but Elizabeth fumes that it's "bizarre" and not funny at all, and Mark tries to calm her down, and he points out that "they're adults," but Elizabeth worries that they will "keep on doing it," and worries about where they'll keep on doing it, "your place or mine," and Mark stifles a laugh and promises to talk to Holling when Holling comes in to see the pulmonologist that afternoon, and then he cracks up again and Elizabeth looks horrified.

The van driver looks over his shoulder, worried, as Laura continues to pant and wail. She says she can't breathe. Luka says a broken rib may have punctured Laura's lung, and he listens to her chest and asks her to look to the right and then to the left, but when he prompts her to look to the left, she doesn't respond, and Laura's Mom shouts, "Oh my God!" Luka reports that he doesn't hear any breath sounds, and LM demands to know what's happening, and Luka explains that Laura has a tension pneumothorax, which means that an air leak has collapsed her lung and the pressure is preventing her heart from beating. Thank you, writers, for having Luka explain that, because I never knew what that meant before. Luka starts to swab Laura's chest with a cotton ball, telling LM that he's going to stick a needle into Laura's chest to relieve the pressure. No sooner has he inserted said needle, of course, than the van goes over a bump, and you'd think the driver could have steered around it since we all saw it coming FROM WICHITA, but Luka just looks grim and takes the needle out. "Wait, why is she bleeding?" LM blares, and Luka admits that he might have nicked an artery when they went over the bump, and LM bleats, "An artery?" Luka hands her a pad and tells her to keep pressure on the source of the bleeding, and the driver calls out over his shoulder, "Is something wrong back there?" and LM yells, "These pads are soaked!" and Luka tells her just to keep pressing them and whips out his cellphone: "Yeah, this is Kovac. Yeah, I'm coming in with a major trauma -- clear a room and get four units of O-neg. Yeah." Suddenly, I have a flashback to my old boss, an Austrian guy almost as good-looking as Goran Visnjic, who had very good English but prefaced every sentence, curse, pronouncement, or utterance of any kind with the word "yeah," so we heard a lot of "yeah, shit!" around the office. Anyway, Luka hangs up and yells at the driver to "go faster -- we need to be there now!"
