While Foreman totally disappears, Cameron and the three Cottages are at Stewart's front door. Or, at least, his second front door. Taub wonders why Stewart has two locked front doors. Duh, Taub. He's agoraphobic. He can't have enough doors locking the outside world away from him. Stewart doesn't want to let anyone in, and Cameron tells him to take his time, "we're not going away." This doesn't sit well with Kumar, who didn't spend all that time in medical school to stand outside some guy's second front door. He tells Cameron to be honest with the guy, since he's probably all PTSD'd out from the shooting that also killed his girlfriend (thanks for shoehorning that fact in there, Kumar) and doesn't trust anyone. Someone should tell Stewart that people can be shot inside their homes, too. Or maybe that would be cruel. Which means it's only a matter of time before House does it! Cameron thinks for a minute before turning back to the second door and telling Stewart that they will not, in fact, wait forever for him to get his shit together and they've got a whole hospital full of patients who actually want to be treated to get back to. Hmm, yeah, speaking of those patients, they'd better be getting this same personalized care with four doctors hovering over each of them. It's not fair that Stewart gets all this attention just because he won't go to the hospital, and that it's taking staff members away from the people who will. Stewart agrees to let only one person in, but Cameron says that's not good enough. She'll examine him in one room and the other three will search the rest of the house for toxins, but won't violate Stewart's inner sanctum. Stewart signals his agreement to these conditions by opening the door.
Now he's got a brain scanning hat on and Cameron gets ready to provoke a seizure. She sits on Stewart's bed, and he's all nervous because he so rarely (a.k.a. never) has guests, let alone a pretty girl in his bed. Cameron stands up so he can collect himself, and Stewart recognizes her voice as the person who helped him through his nasty flu spell last year. He says he was expecting someone older and probably less attractive. "Must have been scary being shot," Cameron says, ready, willing, and able to dredge up what is clearly the worst thing that has ever happened in this guy's life. Stewart is not so eager to do so, and tells her to stop. He claims that he has everything he needs in this house to make him happy. He works from home and makes "good money" writing tech manuals, although I can't see how that's lucrative, and gets everything he needs delivered to him, including medical care. "You don't seem very happy," Cameron says. Stewart reminds her that right now, he's too sick to be very happy.
