The House M.D. episode featuring House and Amber’s bus accident is titled “House’s Head.”
“House’s Head” is the first part of a two-part fourth-season finale. House wakes after a bus crash with a severe headache and incomplete memories. He realizes that he was on the bus with someone important but cannot initially identify the person or reconstruct what happened.
The episode follows his attempt to recover the missing memory while colleagues investigate the accident and its medical consequences. Its fragmented viewpoint makes the audience experience House’s uncertainty alongside him. The conclusion leads directly into “Wilson’s Heart,” which supplies the emotional and medical resolution.
Amber is James Wilson’s girlfriend at this point in the story, so the accident has consequences beyond House’s own injuries. The two episode titles are often confused: “House’s Head” centers on the crash and House’s search for the missing memory, while “Wilson’s Heart” continues the aftermath.
