Which House M.D. episode title combines “House’s” with “Head”?

The House M.D. episode titled “House’s Head” is the first part of a two-part fourth-season finale. It follows House after he experiences a severe memory problem and tries to reconstruct events from a night he cannot fully remember.

The episode uses an investigation structure in which House searches for a patient while also trying to recover missing details. Its cliffhanger leads directly into “Wilson’s Heart,” which concludes the story.

Because both titles refer to body parts and belong to the same two-part event, viewers sometimes reverse them. “House’s Head” comes first, while “Wilson’s Heart” is the second episode.
