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

“Wilson’s Heart” is the title of House M.D.’s season-four finale. It is the second part of a two-episode story that begins with “House’s Head,” the season-four penultimate episode.

The story follows House after he suffers a serious injury and struggles to recover memories from a night he cannot fully recall. The investigation gradually reveals what happened to a group of doctors and leads to a medical emergency involving Amber Volakis, who had been associated with James Wilson. The episode focuses heavily on Wilson’s friendship with House and the emotional consequences of the case.

“Wilson’s Heart” aired in 2008 and is widely regarded as one of the series’ most dramatic episodes. Its title points to Wilson’s personal connection to the central crisis rather than to a separate cardiology storyline. “House’s Head” is sometimes given as the answer because it is part of the same two-part event, but it is the preceding episode, not the season-four finale. The finale is specifically titled “Wilson’s Heart.”
