Honeymoon is the 1st season finale episode of House which first aired on May 24, 2005. House’s ex-girlfriend Stacy Warner’s husband Mark is reluctant to be treated by House, but they eventually corral him and get him into the hospital. Although Mark insists he is fine and the initial tests bear him out, it is soon clear that there is something seriously wrong with him. House is torn emotionally between wanting to please Stacy by curing Mark and letting Mark die: either so she might come back to him or to hurt her for the way she hurt him. The matter only gets worse when the only way to confirm House's diagnosis is to risk Mark's life.
