In House M.D., which character is known by the nickname “Thirteen”?

Remy Hadley is the House M.D. character known by the nickname “Thirteen.”

Olivia Wilde portrays Hadley, who joins House’s diagnostic team during the fourth season. The nickname comes from the number assigned to her as a candidate during House’s unusual selection process for new fellows. House and the other doctors often use the number even after her identity is known.

Hadley is a physician with a specialty in internal medicine. Her storylines include her bisexuality, her diagnosis with Huntington’s disease, and the difficult choices created by an inherited, progressive neurological condition. These plots give the character a personal connection to uncertainty and medical testing.

“Thirteen” is frequently confused with other female members of House’s teams, especially Cameron and Amber Volakis. Those are separate characters. Hadley’s formal name is Remy Hadley, while “Thirteen” is the distinctive nickname most associated with her time on the show.
