Which House M.D. episode introduced the character Amber Volakis?

“The Right Stuff” introduced Amber Volakis in House M.D. The episode is the first part of the fourth-season storyline in which House recruits a new diagnostic team through a highly competitive elimination process.

Amber, played by Anne Dudek, is one of the applicants competing for a place on House's team. Her aggressive ambition and willingness to challenge House earn her the nickname “Cutthroat Bitch,” a label used by other characters rather than her formal name.

The episode takes its title from the 1983 film The Right Stuff, and its structure turns the hiring process into a medical competition. House begins with a large group of applicants and progressively dismisses candidates until only a smaller team remains.

Amber's introduction is distinct from the later episodes that develop her relationship with Wilson and her eventual fate. She should also not be confused with Remy “Thirteen” Hadley, played by Olivia Wilde, who was another major fellow selected during the same season-four recruitment arc.
