Which House M.D. character is nicknamed “Cutthroat Bitch”?

Amber Volakis is the House M.D. character nicknamed “Cutthroat Bitch.”

Amber is played by Anne Dudek and becomes one of the applicants competing for positions on House’s diagnostic team during the fourth-season hiring storyline. House gives her the insulting nickname because of her aggressive competitiveness and willingness to eliminate rivals.

The nickname is a character label within the drama, not Amber’s official name or medical title. She is a physician who ultimately becomes closely connected to James Wilson, creating further tension in House’s personal and professional life.

Amber’s storyline becomes especially important near the end of season four and continues into the fifth season. The character is often confused with Thirteen because both entered the show during the expansion and reorganization of House’s team, but Thirteen was played by Olivia Wilde, while Amber was played by Anne Dudek.
