[calyman]

He definitely appears to suffer from some mental illness but it most certainly isn't scizophrenia. I think it's more likely that he has some combination of OCD and that he displays clear sociopathic trends.

He insists on things being as he wants them, he insists on people telling the "truth", though this requirment doesn't necessarily apply to himself. He records friends telephone conversations and will go to extraordinary lengths to prove unimportant points about what is said.

He holds people to account for any perceived wrongdoing, though again he himself is not bound by such strictures. He will obsess on the most innocuous things, like his irrational hatred/friendship of Ben/Josie.

He displays no real human warmth or empathy towards others, will suddenly alter his emotions if key words are said by others. He pretends ignorance of others motives, yet indicates he knows exactly what they are thinking on other occasions. He fails to respond to others emotions, always centering such concepts back to himself. He doesn't like "the mean girls", yet built a "deep" friendship with Daoimhe over 2 days. He acts and speaks innapropriately and at the most innapropriate times (in the bedroom while others are trying to sleep).

In short, it's clear he does have some mental illness bordering on OCD/sociopathic tendencies, but is most certainly not schizophrenic.
