Wilson finds House making a passive-aggressive peanut butter sandwich, which is all that break room seems to be good for. Foreman walks in with the last of his stuff. It's taken him weeks and weeks to move out of that office. He stops and looks at House expectantly. "This is it," he says, pointedly. When House doesn't respond, Foreman says he appreciates the opportunity House gave him. "I thought you were the best man for the job," House says, with a glance at Wilson, "which is why I want you to stay. You're an important part of the team. I need you." Well, there it is. We all knew it was going to happen, and it did. Foreman will decide to stay, House will rehire Chase, and everything will stay the same going into Season Four. Right? "I know. But I don't need you," Foreman says. Okay, maybe not. House says that he just solved an awesome case -- a case that Foreman gave up on. Okay, but House gave up on it too. He shut the machines off with no idea her heart would start again. In fact, we still don't know how it managed to do that after being stopped for a day, and we never will. Oh well! Foreman says House is just addicted to mysterious medical cases and cares more about them than the patients they affect. "I don't want to solve cases," Foreman says. "I want to save lives."
And then House gets a little angry. No more of this "saying what Wilson told him to say" BS; it's time for a hard dose of the truth! House doesn't think Foreman cares about the patients any more than he does. Foreman only cares about Foreman. Wilson watches another one of House's bridges go down in flames and resignedly lets out a warning "House," knowing it's already too late. House accuses Foreman of being the real selfish bastard here -- he's drawn out his goodbye for three weeks just to make himself feel important. Foreman stops for a second and looks like he might actually be taking in what House is saying. But then a sneer appears on his face and he turns and leaves. "Nice try," Wilson says. House says nice tries are worthless. That theory is why he solves the cases and saves the lives other doctors can't. Including Foreman.
When House returns to his office, he finds Cameron there, sitting in his chair and looking creepy. She hands House the resignation letter I'm guessing she typed up while having sex with Chase. Seriously, when did she have time to do all this? Whatever. "I've gotten all I can from this job," she says. Of all the Cottage-leaving explanations, hers makes the least sense, and that's saying a lot when you look at Foreman, who didn't want to turn into House and thought being near him would make him uncontrollably so, and at Chase, who randomly got fired for being around too long. House asks Cameron what he's supposed to do now. She says she expects him to move on and be just fine. "I'll miss you," she says. It gets less and less genuine every time she says it. She leaves the office and no doubt goes to every single employee of PPTH and tells them she'll miss them, too. Except for the Weird Night Janitor Who Wears His Pants Backwards. No one talks to him. For House's part, he looks less sad about what just happened than...kind of blank, really.
