In House M.D., which episode introduced Dr. Remy Hadley, known as Thirteen?

“The Right Stuff” introduced Dr. Remy Hadley, known as Thirteen, in House M.D. The episode is the third-season premiere and first aired on September 5, 2006.

Thirteen, played by Olivia Wilde, enters the story as a candidate for House’s new diagnostic team. Her nickname comes from the anonymous numbering system used during the selection process, where applicants are identified by numbers rather than names. She is eventually revealed to have Huntington’s disease, a progressive inherited neurological disorder, which becomes an important part of her character arc.

“The Right Stuff” follows House as he evaluates a large group of applicants after the previous team has been dismantled. The episode’s title refers to the competitive search for doctors capable of working with House’s demanding methods. The hiring process continues across several episodes rather than resolving instantly.

The character’s name is Remy Hadley, but the show and its audience commonly use “Thirteen.” That nickname should not be confused with the episode title “Lucky Thirteen,” which comes later in the series and focuses more directly on her personal life.
