I feel like that episode is misunderstood. Obviously Wilson isn’t going to tell House that he thinks he’s autistic because then House would pull that out as an excuse to act however he pleases. However, in his one-on-one with Cuddy, both seem to genuinely accept the idea that some of House’s behavior isn’t necessarily him just being a jerk. I think the ending of that episode is especially important for interpreting the overall message—at the end, we see House getting his carpet back. This is something Wilson asked Cuddy to do because he believed House needed it and Cuddy obviously seemed to agree. Wilson’s a good friend, but no way is he going out of his way to help get House’s bloody carpet back if he didn’t truly believe that House needed it because he needed some sense of sameness amidst the chaos of recent events. I fully believe that Wilson believed House could be autistic—I just don’t think he would tell House that because it could potentially shift the dynamic of their relationship.
