Dr. Remy Hadley, better known as "Thirteen", is a fictional character on the Fox medical drama House. She is portrayed by Olivia Wilde. She is part of the new diagnostic team assembled by Gregory House after the disbanding of his previous team in the third season finale. The name "Thirteen" comes from the character's introduction: House assigned her the number during an extended competition for the job and persistently used it in reference to her; she did not correct him with her real name, and the nickname stuck. Her last name was not revealed on the show until the end of the fourth season, when it is spoken by hospital administrator Lisa Cuddy in "House's Head", to which House jests that "She [Cuddy] doesn't even know your [Thirteen's] name." Beginning with the fifth season, she is regularly referred to as "Dr. Hadley", although as of "Adverse Events", her first name has not been spoken on the show.
"Thirteen" has been reluctant to reveal information about herself within the show. Early on, House tried to guess what her big secret might be, such as asking if she was the "daughter of an alcoholic father". Thirteen responds with "wrong again". In "Mirror Mirror", a patient who mirrors the most dominant personality present describes himself as "scared" when alone with her.
In the eighth episode of the fourth season, "You Don't Want to Know", "Thirteen" tells House that her mother died from Huntington's disease, but she does not wish to know if she carries the gene, because not knowing allows her to summon the bravery to do things she thinks she can't do. House does obtain a sample of her DNA and has the test performed, but in the end throws out the envelope containing the test results unopened. In the season 4 finale, it is revealed that she does indeed carry the gene for Huntington's.
In "97 Seconds
", "Thirteen" correctly diagnoses a collapsing and disabled patient with Strongyloides
, and treats him with ivermectin
, but the patient fails to take the pills because his English Shepherd mobility assistance dog
eats them, causing the death of not only the patient but the dog as well. House chastises her about not supervising the patient taking the medicine, but does not fire her because he feels she will not make the same mistake again. At the end of the fellowship competition, Cuddy tells House that, since he already has Eric Foreman
on his team, he may only hire two additional people. So, House fires Thirteen and Amber, claiming that fellow applicants Chris Taub
and Lawrence Kutner
outperformed her, and that if he could keep Thirteen, he would, but secretly knowing that Cuddy would want at least one female doctor on the team and would demand that he hire Thirteen. This is exactly what happens, putting Thirteen on House's team of four, which is what he had wanted.
Concept and creation
Along with fellow actors Peter Jacobson
, Kal Penn
, and Anne Dudek
, Wilde did not know which character would be cut until the actors were given the scripts, which she thought improved the acting during the "Games" story arc. However, the story arc inspired a spirit of camaraderie between the actors instead of competition, due to the high-profile roles. While Thirteen's name was originally intended to be revealed during the story arc, the production team decided against doing so. "Thirteen's" actual name was on all documents, including the call sheets, with the word "Thirteen" to further the in-joke in the show's narrative between House and "Thirteen" that he could simply check her file to find out her name. Wilde describes "Thirteen" as a "big bowl of secrets", one such being the possibility of the character having Huntington's disease
, in stark comparison to her own openness.
Thirteen's sexuality was written ambiguously: Foreman and House have suggested that she is bisexual; and Thirteen herself hints that she is bisexual. In response to the ambiguity, Wilde confirmed in July 2008 that her character is bisexual, the second time she has played a bisexual character (the first being on the O.C. as Alex Kelly).
"Thirteen" has often been compared, sometimes negatively, with Allison Cameron, the previous female diagnostician, even by the actress Jennifer Morrison who portrays Cameron. Wilde described "Thirteen" as "almost the opposite" to Cameron, who is "compassionate and emotional", and attributed the comparisons to the similarity in the tasks that House delegates to both characters, and that "with two girls on a show, people are always going to compare them."
Although the producers have given the character a full name, and have told Olivia Wilde what it is, they have chosen to keep it a secret from the viewers as part of the ongoing relationship between the character and House. The first onscreen reference to the character's full name comes in the episode "Mirror Mirror"
, when a ballot paper is handed out with the names of all the fellowship candidates. This reveals Thirteen's name to be Remy Hadley. During a season 5 cast interview, Wilde's character is listed on-screen as "Dr. Remy Hadley." Later, in the Season 5 episode "Adverse Events"
, Thirteen refers to herself as "Dr. Hadley", as does the patient.
