Suddenly, Nurse NotCarla and the Neanderthal run out of the CT scan room. They head for the SWAT team. Cuddy asks NotCarla why Jason released them. NotCarla says he didn't -- House convinced him to give up his gun, and they took off. House, Hadley, and Kid, on the other hand, decided to stay behind. That means that House, Hadley, and Kid are dumber than a guy who looks like a caveman.
Sure enough, the gun is lying next to House while he runs another CT scan. Kid decided to stick around, saying he might as well since it's safe now and he's curious. Yeah ... Kid gets beaten up a lot because he's an idiot. The phone rings, but no one bothers to answer. Why isn't the SWAT team charging in right now? Everyone in this episode is useless and stupid. The scan complete, Jason asks House to show him the tumor before the SWAT team enters and takes him away. But, House says, "there isn't one." His diagnosis was wrong. He still doesn't know what's wrong with Jason. After all that, he hasn't gotten his precious answer. Cry me a river. "Thanks for trying," Jason says, taking this pretty well. And then House picks up the gun and hands it back to Jason, much to Kid's annoyance. Hadley just stands there like a zombie. Any one of them could, you know, rush House and try to get the gun back before it falls back in the hands of the crazed hostage taker, but no.
So House is inexcusably stupid for giving the gun back and the SWAT team is, too, for sitting around letting the phone ring instead of charging the room. I guess House is just that determined to get his diagnosis, but why would he basically risk Kid and Hadley's life to get it, too? Why risk anyone's life at all? Give Jason the gun back with the bullets gone. Let the SWAT team think the guy is still a threat while continuing to look for a diagnosis, knowing that Jason can't kill them anymore. Or let Jason get arrested and then diagnose him from fucking jail! These are all good options! There's no reason AT ALL why House would give the loaded gun back when he doesn't have to, especially when he's been shot before and know it's not fun. Whatever.
House finally answers the phone to tell the SWAT team that Jason overpowered him and got the gun back. He hangs up, and Hadley accuses House of being a coward. He'd rather risk other people's lives and find his answer than not know and be just another ordinary doctor. House says that he's just arrogant. The real coward is Hadley, because she's afraid to die and is trying to make it come even sooner so she feels like she has control. You know who isn't a coward? Nurse NotCarla. She was awesome. Meanwhile, the Kid doesn't really care who the coward is. He just wants to leave. Should've thought about that before you stayed behind, Kid! Now you're stuck. House won't let Kid go, saying they might need him.
