What is the title of House M.D.’s second-season finale?

The second-season finale of House M.D. is titled “No Reason.”

“No Reason” is the twenty-fourth episode of the show’s second season and originally aired in May 2006. The episode begins after Gregory House is shot by a former patient’s husband, creating a story that blends an apparent medical emergency with psychological and hallucinatory elements.

The episode explores House’s perceptions while he is injured and receiving treatment. As the story progresses, the boundaries between actual events and altered experiences become increasingly difficult to trust. Its structure allows the series to examine House’s pain, drug use, and emotional defenses through an unusually subjective viewpoint.

The title is distinct from several later House M.D. episodes that focus on major character crises. “House’s Head” and “Wilson’s Heart” are season-four episodes, while “Everybody Dies” is the series finale. Those titles are common mix-ups because all involve prominent, high-stakes storylines, but “No Reason” specifically concludes season two.
