The House M.D. episode featuring Amber Volakis’s death is titled “Wilson’s Heart.”
“Wilson’s Heart” is the season-four finale and originally aired on May 19, 2008. It follows the aftermath of a bus accident that leaves House struggling to reconstruct what happened while Wilson’s partner, Amber Volakis, is critically ill.
Amber, played by Anne Dudek, had been a competitive applicant for House’s diagnostic team and later became romantically involved with Wilson. Her death deeply affects Wilson and becomes one of the most consequential emotional events in the series.
The episode is paired with “House’s Head,” the preceding season-four episode. “House’s Head” establishes the mystery surrounding the accident, while “Wilson’s Heart” reveals the diagnosis and completes the storyline. The titles are therefore related but refer to different episodes.
