Thirteen (House) - Character History

Character History

In "Lockdown", Thirteen says she went to Newton North High School. In "Epic Fail", Thirteen reveals she attended Sarah Lawrence College. 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 fellow applicants Chris Taub and Lawrence Kutner outperformed her, and that if he could keep Thirteen, he would. Cuddy overrules House's decision, forcing him to accept a woman, realizing only a minute later that this had been House's plan from the start.

At the end of the fourth season, Thirteen is diagnosed as having the mutated Huntington gene. After nearly dying when forcibly injected with several medicines in "Last Resort", she asks Foreman to admit her to his Huntington's drug trial. Several episodes later, the couple embark on a relationship, which affects Foreman's professional judgment to the extent that he fixes the drug trial, which causes serious side-effects in Thirteen. Foreman almost loses his medical license, resulting in House ordering the couple to break up. The couple fake a split and continue their relationship in secret, but come public after House discovers they are still seeing each other. As Foreman takes his position after House quits, he fires Thirteen in "Epic Fail" in order to save their relationship, but they end up breaking up as a result.

In the sixth season episode "Instant Karma", Thirteen buys a one-way ticket to Bangkok, Thailand and is seen boarding the plane. In the episode, "Teamwork", Thirteen eventually returns to House's Team with Chase, Taub, and Foreman. She subsequently requests a leave of absence in the season finale "Help Me", citing personal reasons.

In the season seven premiere, Foreman finds information about a Huntington's drug trial in, and flight info for, Rome, but Thirteen disappears without saying goodbye. Foreman then discovers that the clues about Rome were purposely planted by Thirteen as a red herring. Thirteen returns in the show's 150th episode, "The Dig", in which it is revealed that she has been in prison for the past six months and grew up in West Virginia. Thirteen reveals to House that she had a brother who developed Huntington's; she helped kill him in order to end his suffering. House later tells Thirteen that he is willing to euthanize her if she wants him to do so.

In "After Hours", a then unknown woman arrives at Thirteen's apartment, with a serious wound in her abdomen. She is revealed to be a cell mate of Thirteen's from prison. Thirteen phones Chase requesting help on false pretenses, bartering on their relationship to convince Chase to bring her medical supplies without explanation. After it becomes clear the woman will die without a hospital, Chase engages in a physical confrontation with Thirteen to get the patient to the hospital. After the two drive the woman to the hospital, she awakes alive but in custody. Thirteen apologizes, but her friend lashes out, claiming she only used Thirteen because she needed someone to talk to in prison.

In "Charity Case", Thirteen was called in once more by House to help solve a case. Thirteen then decided to join the team once more. In the end, House saw that Thirteen was happy with her girlfriend and fired her once and for all so she can live out her last days being happy. She made her final appearance in the series finale "Everybody Dies".
