Olivia Wilde played Remy Hadley, known by the nickname Thirteen, in House M.D. The character joins House’s diagnostic team after the selection process shown during the fourth season.
“Thirteen” comes from the number assigned to Hadley during the large fellowship competition House conducts after his original team changes. Her reserved personality and reluctance to discuss her private life make the nickname a lasting part of her identity at the hospital.
Hadley is a specialist in internal medicine. Her storyline includes Huntington’s disease, because she carries the gene for the inherited neurodegenerative disorder. The diagnosis creates a long-running question about whether and when she will develop symptoms, and it influences her relationships and attitude toward medical uncertainty.
Wilde played Thirteen from the fourth season onward, with periods in which the character was absent because of prison, medical work, or other story developments. She later left the regular cast while continuing to appear in later episodes.
