You Don't Want to Know

House treats a magician but comes to believe he's faking illness to cover up his own incompetence. Meanwhile, House pits the fellows against each other in his version of an immunity challenge.

Ugly

A film crew and the candidates are following around House distracting him while he is trying to diagnose a teenager who suffers from a heart attack prior to a serious plastic surgery.

Whatever It Takes

Based on practically no information and no medical history about a mystery patient sent by the CIA, House is using some unorthodox methods to diagnose and treat him. Meanwhile the remaining candidates are questioning Foreman's judgment.

Last Resort

A gun-wielding man from the waiting room at the Princeton-Plainsboro clinic takes House, Thirteen and several patients from the waiting room hostage in Cuddy's office. The man claims to be sick with a long undiagnosed illness and demands medical attention from the best doctor in the hospital, threatening to kill any hostages necessary along the way.
