On their way to the meeting room, Chase asks Foreman about Hadley, urging him to reconsider firing her. Oh, please. Chase doesn't care about Hadley. Why would he even bring her up? Foreman says he knows he made the right decision -- it was either risk her dumping him for firing her or have the relationship end for sure because they couldn't work together. With that, they enter the meeting room, only to stop short in horror/shock and in one case (Cameron) happiness when they see House seated at the head of the table. "Oh my god, it's three years ago. Does that mean I'm still crazy?" he says. Once again -- House never was crazy. I mean, I thought he pretty clearly was, but then they gave him anti-depressants and made him talk about his feelings and sent him on his way without ever addressing the hallucinations, so apparently I was wrong. Foreman: "you're back?" Chase: "we're just helping out." Cameron: "you look good." Oh, Cameron. You never change. House already knows the situation, since he "ran into" Hadley while she was cleaning out her locker. Hadley, you can't clean your locker out on the same day as your firing? Really? Foreman makes it clear that he and Hadley are still together (although it seems that Hadley told House the opposite) and asks if he is coming back to PPTH. "Sort of," House non-answers. He won't have his medical license for another month, so he's perfectly happy to let Foreman take the reigns and just "pitch in" every once in a while. It's full of holes, but it's so nice to see House, Cameron, Chase, and Foreman together again that I will take it.
Chase tries to talk about the case. Dibala thinks his lung ulcers are from an assassination attempt using polonium, but Foreman says the FBI has already ruled that out. "Acid reflux," Cameron guesses. Yes, Cameron, it's acid freaking reflux. Give the guy barfing copious amounts of blood some Tums and send him on his way. Foreman likes malaria, noting that Dibala had a bug bite on his hand that could be from a mosquito that was carrying the disease. That's quite a reach, but he's ready to throw some anti-malaria pills at the guy without testing for it first. House clears his throat loudly and conspicuously and tells Foreman that malaria is a rushed diagnosis made only to get Foreman out of the room and away from House. His diagnosis is dioxin poisoning with the bug bite actually being chloracne, a symptom of it. Chase likes it, of course. Foreman tells them to start treating Dibala for dioxin with "olestra." Olestra? Isn't that the stuff they used to put in potato chips that gave everyone diarrhea? Bad news for Dibala! With Chase and Cameron gone, Foreman asks House why he didn't just say dioxin in the beginning. "I was hoping you'd get there on your own," House says. Zing!
