I'm rather disgruntled to see once again the stupid trope that people just need a pep talk and to decide to get over it to solve their mental illness. I really don't think phobias quite work this way. I wouldn't have minded so much if the point where he decides to leave his house had been earlier for his own survival, and then he then had somehow seen that as a starting point to work on his phobia rather than rearrange his life around it or something. But have him resist throughout, and then just leave on his own in the end, after House had scolded him as if his former problem wasn't real, that sucked.
On House and Wilson, I don't even know what to say to that anymore. Wilson is really messed up, isn't he? I mean, this plan that he asks Cuddy because he wants to help House, it's just-- *wordless flail*
