“The Right Stuff” was the first House M.D. episode to feature Dr. Remy Hadley, known as Thirteen.
The episode is the fifth-season premiere and follows House’s effort to rebuild his diagnostic team after major changes at Princeton-Plainsboro. Thirteen is introduced as one of the physicians competing for a place on the new team.
Olivia Wilde played Thirteen, whose nickname refers to her position in the selection process. The character’s medical knowledge, reserve, and personal history made her an important member of House’s later diagnostic teams.
“The Right Stuff” is sometimes confused with “Lucky Thirteen,” a later episode whose title directly references the character. It is also distinct from “The Itch,” the episode that marked Thirteen’s return after an absence. The season-five premiere aired in September 2008.
