Foreman and Cameron do the bone scan. Cameron confronts Foreman, asking him what Chase is lying to her about. Foreman says he told Chase to talk to her, and he's telling her to talk to Chase. Foreman is really good at communicating with his loved ones, so you know this advice is sound.
The next morning, House decides to skip breakfast and fill up on mindgames instead. He tells Wilson he's having auditory hallucinations at night. Wilson says there's probably rational explanation for it, but House says he checked everything out and the only answer is he's losing it again. And worse than last time, since he can't blame the Vicodin. Which I guess is the final word on what caused House's hallucinations before. Even though that doesn't make sense. And Nolan said it couldn't have been the sole cause. But whatever. He says he's going back to Mayfield. "Okay," Wilson shrugs. That wasn't the answer House was expecting. In fact, he was expecting Wilson to confess that he was whispering. But Wilson realized that and wasn't about to play along. He calls House an "ass" for using Wilson's conversation with his dead girlfriend as a way to fuck around with him. Yeah, I really don't get why House did that. We're supposed to think he's not being such a dick anymore, right? It's not like Wilson knew that his whispering was tormenting House and was doing it on purpose. Or maybe he was, but sub-consciously. Anyway, House apparently feels left out because Wilson is talking to the air when he could be talking to his friend House. Although it's not like House talked to Wilson when Wilson asked him to, so whatever. Wilson says that's not the point -- he misses CTB and talking to her makes him feel better. "You don't," he says.
