17. The Social Contract

House and the team take on the case of Nick Greenwald ( Jay Karnes ), a book editor who loses his inhibitions and starts insulting co-workers at a dinner party one night before falling ill. The team realizes Nick has frontal lobe disinhibition, which has caused him to lose his filter and vocalize all of his innermost thoughts, resulting in extremely insulting outbursts. As Nick's free speech leads to some amusing and insightful comments regarding the team, he must deal with the consequences of being unable to lie to his wife and everyone else important in his life. Meanwhile, House suspects Wilson and Taub are keeping something from him when he catches them both in a lie. Final diagnosis: Autoimmunity secondary to Doege-Potter syndrome Absent: Jennifer Morrison as Allison Cameron
