Dr. James Wilson
James Wilson is the Head of the Department of Oncology at Princeton Plainsboro.
He serves as House's best friend and foil. The pair get along in a strange way, often relying on one another for both advice and insults.
Wilson seems to understand House in a way no one else can. He serves to enable, and to assist, his pal.
House: We are condemned to useless labor...
Dr. Wilson: Fourth circle of hell. Charting goes a lot faster when you eliminate all classic poetry.
House: Writing down what we already know to be read by nobody. Pretty sure Dante would agree that qualifies as useless.
Dr. Wilson: You're over two weeks behind in your charting...
(Dr. Cuddy approaches them, and House throws a piece of paper towards her)
House: Oops... I missed!
Dr. Cuddy: And is there a paternity bet on the father of the patient?
House: Doesn't sound like me.
Dr. Wilson: Well, it does, actually, but doesn't mean you're guilty.
