House M.D. Season 3 Episode 22

A 19-year-old college student, Addie, starts coughing up blood during karate class and ends up one of House's cases. Foreman hands in his resignation before treating the woman and refuses to explain why. Although her symptoms show no signs of it, House is convinced that an infection is causing Addie's bleeding. Her lungs start filling with fluid and House's team believes a toxin or cancer is to blame for Addie's illness but are unable to change House's mind. Addie continues to get worse and House wants to do an extremely risky life-or-death treatment in order to confirm his diagnosis; the team starts to ask whether House cares about making a diagnosis more than Addie's own life. Meanwhile, House becomes interested in Honey, a young, attractive nutritionist who brought her boyfriend to the clinic for treatment. He gets her to fill out an employment application (for Foreman's soon-to-be vacated position) and arranges to meet her again in a more casual situation.
