Which House M.D. episode is the first part of the two-part season-four finale?

“House’s Head” is the first part of House M.D.’s two-part season-four finale. It is followed by “Wilson’s Heart,” which completes the storyline involving House’s search for a missing memory and the consequences of a bus accident.

The episode uses an unusual structure: House suffers a head injury and tries to reconstruct events from fragmented recollections. The mystery gradually becomes connected to a patient and to members of House’s team, creating a cliffhanger that continues directly into the next episode.

“House’s Head” aired in 2008 and was paired with “Wilson’s Heart” as the season’s concluding event. Viewers sometimes reverse the titles because Wilson becomes central to the second episode, but the order is clear: House’s Head comes first, and Wilson’s Heart follows.
