Olivia Wilde played diagnostic fellow Remy Hadley in House, M.D.
The character is better known by the nickname “Thirteen,” which House's team uses for her after the applicants are assigned numbers during the selection process. Hadley is a physician with a guarded personality and strong diagnostic ability.
Her personal storyline includes the fact that she carries the gene for Huntington's disease, a progressive inherited neurological disorder. This plot becomes one of the character's defining sources of uncertainty and emotional conflict.
Remy Hadley is sometimes identified only as Thirteen, but the canonical character name is Remy Hadley. She is distinct from Allison Cameron, played by Jennifer Morrison, and Martha Masters, played by Amber Tamblyn.
