What is the name of the bus-accident victim who dies in House M.D. season 4?

Amber Volakis is the House M.D. character who dies after a bus accident in season 4.

Amber, played by Anne Dudek, is one of the doctors competing for a place on House’s diagnostic team during the fourth season. Her aggressive ambition earns her the nickname “Cutthroat Bitch,” although the character is also shown as highly capable and emotionally significant to Wilson.

At the end of the season, Amber and House are involved in a bus crash. Amber has been taking amantadine, a drug that her damaged kidneys cannot properly clear. The resulting poisoning causes severe illness, and the medical team cannot save her. Her death profoundly affects Wilson and contributes to major changes in House’s behavior.

Amber’s storyline continues through hallucinations and memories after her death, so she appears in later episodes without being alive in the story’s present timeline. This can make her status confusing to viewers who remember seeing her after the bus crash.
