In House M.D., Remy’s surname is Hadley; she is nicknamed Thirteen.
Dr. Remy Hadley joins House’s diagnostic team during the fourth season and is played by Olivia Wilde. The nickname “Thirteen” comes from her numbered position during the large fellowship competition House conducts to select new team members.
Hadley is a physician with a specialty in internal medicine and neurology-related expertise. Her character’s story includes a family history of Huntington’s disease, which becomes a major emotional and medical thread. The show also explores her relationships, secrecy, and difficulty discussing her own future.
The surname is frequently missed because the character is overwhelmingly called Thirteen. She is not Amber Volakis, another finalist in House’s fellowship selection, and she is not Allison Cameron, a member of the original team. “Remy Hadley” is the character’s full name, while “Thirteen” is her enduring series nickname.
