Genre: Mystery

The team takes on the case of a fitness guru on an all-natural diet who collapsed while filming a video. Meanwhile, Foreman conducts Huntington's Disease drug trials and Thirteen signs on as a subject, Cuddy is forced to move into House's office, and Kutner uses House's name to run an online medical-advice website.

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.

While Foreman takes on a pediatric case on his own, the rest of the team deals with a 16-year-old factory manager and emancipated minor who collapses at work. When Foreman's patient takes a turn for the worse, he's forced to question whether he can deal with the situation on his own, or if he needs House's help.

The team must treat an agoraphobic who refuses to leave his house, and have to work around Cuddy, who is less than thrilled at having hospital equipment relocated. Meanwhile, House is plagued by an itch, and Cameron and Chase have relationship issues.
