What is the title of the second part of House M.D.’s fourth-season finale?

The second part of House M.D.’s fourth-season finale is titled “Wilson’s Heart.” It follows the first part, “House’s Head,” as House tries to reconstruct events surrounding Amber Volakis’s medical crisis.

The two-part finale originally aired in 2008 and is structured around House’s damaged memory after an accident. The investigation gradually reveals what happened during a night involving House, Wilson, and Amber. The title points to Wilson’s personal connection to the case rather than identifying a medical procedure.

Amber, played by Anne Dudek, had been a member of House’s diagnostic team during the fourth season. Her relationship with Wilson makes the case especially consequential for him, while House’s friendship with Wilson becomes central to the emotional stakes.

“House’s Head” and “Wilson’s Heart” are sometimes treated as one extended finale, but they are separate episodes with distinct titles. “Wilson’s Heart” is the concluding installment and is commonly recognized as one of the series’ most important early turning points.
