What was the title of the House, M.D. episode in which House faked his death?

House faked his death in the House, M.D. episode “Everybody Dies.”

The episode is the series finale and aired on May 21, 2012. House makes the decision after discovering that his best friend, oncologist James Wilson, has terminal thymoma and may have only months to live.

A building fire gives House an opportunity to stage his death. He manipulates dental records and switches identities with a dying patient, allowing his colleagues to believe that he died in the blaze. The plan is designed to keep him out of prison and free him to travel with Wilson.

The finale reveals the deception to viewers while preserving the emotional impact for the hospital staff. House and Wilson leave together on motorcycles, making the episode’s central resolution a choice about friendship and time rather than a medical cure.
