Foreman is second in charge to House. He was originally hired because he has juvenile record and House needed someone with street smarts.
A neurologist, Foreman isn't the most exciting character on television. He's been labeled a "boring" on more than one occasion on the show, but he is able to stand up to House more than any other team member. He's a pretty quiet, serious indidivual.
Near the end of season five, Foreman began dating Thirteen.
