Alex sits silently in the back of Luka's SUV; Sam is riding shotgun. Luka stares at her; she stares at him; she peeks at Alex; she stares at Luka; she opens and closes her mouth like a bored goldfish. Riveting stuff. Finally, Sam says, "It just sort of snuck up on us, you know?" She's trying to be light about it, but you can tell she's freaking out that the shock will send Alex straight into the arms of that most evil seductress: Arson. "I...I don't think either one of us planned it, right?" Sam says desperately. "Right," Luka quickly agrees. Alex stares out the window wordlessly. "It happens. People date," Sam attempts. Then she scratches her nose. "Are you okay?" Luka asks. "Yeah," pouts Alex. "Want to talk about this?" Luka asks. "No," Alex says. Wow, that was ham-handed. Luka pats Sam's leg sympathetically as she frowns. Linda Cardellini's hair's gotten so much hate for being curly that I'm not going to bag on it, because I have semi-curly hair, and I also think curly hair is gorgeous and gets a bad rap. It is maybe a bit dry, though, or at least the brassy bad dye job makes it look that way. Hope Luka sends Sam to a salon so he can man-to-man with Alex.
Nolan still hasn't stopped shuddering. Pratt and Gallant are concerned about brain damage, and Gallant thinks he needs the hyperbaric chamber. This means they think Nolan needs to be in a highly pressurized environment that doctors use (and the technology of which is associated with the way scuba divers descend and ascend) in order to help the body absorb a lot more oxygen than it normally would. Here, they must quickly reoxygenate the blood, which is currently poisoned with carbon monoxide. But his level is only 35\%, and for hyperbaric therapy, you need 40\% or more -- unless there are signs of brain damage. Pratt wants to put him on a drip and wait and see how he is in half an hour. Gallant theorizes that the baby's toxicity caused a distress that probably kick-started labor. "Good thing, too. Otherwise they'd all be dead right now," he intones. Wait -- a baby that saves lives rather than ruining them? Why, hello, Bizarro Rex. How non-repulsive you look.
