There's air in Ezra's chest. Without even bothering to scrub up or put some gloves on, House sticks a tube in there and the air whooshes out. Ezra's stats return to normal. So House rushed down there to do a simple procedure that any of the several doctors already in the room could do? That doesn't really make sense, unless there's some plot-furthering discovery to be made. Sure enough, while House is stitching up Ezra's chest tube wound and looking around the balcony to see if Cameron's watching him work, his hand slips and the suture needle pokes Ezra's hand. Nothing happens, which House finds odd. So he pokes Ezra's other wrist, which jumps. Ezra only reacts to pain stimuli on his left side. Well, maybe. There's no way to confirm this while Ezra's in the coma. So they'll have to wake him up. You guys, Ezra is going to be so pissed off. Hopefully, they'll have enough time to either think of an excuse as to why he isn't dead or to construct a heaven-looking set so Ezra will think he's dead and the afterlife consists of a bunch of medical tests and feeling a lot like he did right before he "died."
"Don't go towards the light!" House shouts at Ezra as he wakes up. Chase removes the breathing tube and Ezra is all "what the hell?" But House won't give him much time to complain as he tells him that they need to test Ezra's nerves now that he's up and at 'em. Ezra calls House a "huge failure" for still not having a diagnosis and refuses any treatment or tests. House says that he won't kill Ezra and he's assigned a nurse to make sure Ezra doesn't kill himself, so he might as well play along. Because I have a feeling that nurse will be Evil Nurse Brenda, and you do not want to be the subject of her suicide watch. Ezra decides to discharge himself from PPTH, even with the tubes in his chest, and angrily removes various tubes and medical equipment with such vigor that one would wonder why he couldn't have just killed himself if he's so into it. I mean, obviously he can't do it now, but he never seemed too weak or in too much pain to be able to do it before. It makes it hard for me to agree that assisted suicide is the right idea for him when he seems perfectly capable of doing it himself. Anyway, House responds by quickly testing various parts of Joel's withered body for reflex responses. He tickles Ezra's legs and splashes ice water on his abdomen. The left leg twitches, the other one doesn't. And there's no feeling in the abdomen area.
