Keith moans on the pavement. Dan climbs back out and tries his cell phone. It doesn't work. Surprisingly, no one else's does either. And I guess the people are all dead in the other car, because nary a peep's coming from over there. Keith screams, "Is Luke okay?" Dan replies, "He's going to be okay, Keith." Dan runs around to the passenger side of the truck and rips the door off. That's right, he rips the door off with his bare hands. He reaches inside and pulls Luke out of the seat. Yes, it's not like he was just in car accident or anything and, oh, might have a neck or back injury -- because that's not at all what happens on impact. Oh, no, it's fine; Dan can play Rescue Worker and pluck Luke right out of the vehicle without stabilizing his neck or his back. What-freaking-ever. It's bad enough the show's taking the cheap route by having this accident in the first place; we now have to see a totally ridiculous, absolutely inconceivable response to it at the same time. Anyway, Dan hauls a limp, puppet-like Luke out of the car and carries him to his own truck.
At some point, he must have picked Keith up too, because in the next scene, we see Dan squealing into Emergency with his brother in the passenger seat. Dan hops out of the car and grabs Lucas from the back seat; he carries him into the hospital, screaming, "I need a doctor! My brother's in the car, he needs some help." The doctors and nurses are there with a gurney. One of them says, "What happened?" Dan replies, "Car accident!" He lies Luke down on the bed: "He was at the point of impact." The doctor doesn't even examine him. He yells something about a chest tube and cross-typing blood. Then he says, "He's going to need surgery." Dan says, "Do whatever you need to do, doc." And again, the Emergency doctor hasn't even examined Lucas. How in the hell would he know that he needs surgery? "He's a minor?" Dan answers yes. The doctor says, "You're his legal guardian?" Dan says quietly, "He's my son." And all that's just for Dan to admit that Luke's his kid? The doctors roll Luke away into his magical surgery for the magical injuries no one even knows the true extent of yet, and Dan stands at the end of the long hallway, staring down at his flesh and blood. Does no one on the writing staff actually watch ER? Don't they know how this stuff's supposed to be done?
Karen arrives home from Italy looking hot, hot, hot with a new haircut and a beautiful scarf around her neck. She looks around for Keith and Lucas, but doesn't see either of them.
