"TB" takes an unusual twist: House is compelled to treat an internationally famous doctor who treats Africans for TB and who browbeats pharmaceutical makers to donate more and more of their drugs to his cause. The doctor himself now has a bad case of TB. Or does he? This is what House must discover. The episode is full of amusing bits as House is clearly insanely jealous of the guy, who is a smooth talker, completely self-absorbed and handsome as the devil. He very quickly wins over Cameron, and this makes House even crazier. Ron Livingston of "Office Space" fame plays the charismatic physician, and is one of the better guest stars to grace the house of House. As the Season 2 episodes roll on, Wilson has begun to play a larger role as House's only real friend. But his friendship is being stretched thin by House's antics.
