In House M.D., which character uses the nickname “Thirteen”?

Remy Hadley uses the nickname “Thirteen” in House M.D. Olivia Wilde plays Hadley, who joins House’s diagnostic team during the fourth season and remains a major character for much of the series.

The nickname comes from the numbered applicants in the competition House conducts to rebuild his team. Hadley is contestant number thirteen, and the label continues even after her identity and medical background become known. Her character is a physician with Huntington’s disease, a hereditary neurological condition that shapes several storylines.

Hadley’s guarded personality reflects her fear of being defined by illness and her reluctance to discuss her private life. Her relationship with House’s team develops through difficult cases, ethical disagreements, and personal revelations. She is also bisexual, a trait the series treats as part of her character rather than a one-episode detail.

“Thirteen” is a nickname, not her legal name. The character’s full name is Remy Beauregard Hadley. She should not be confused with Amber Volakis, another finalist from the team-selection storyline.
