Remy Hadley

Dr. Remy Beauregard Hadley was a major character on House from the fourth season onwards. She is best and commonly known as "Thirteen" due to her number card during eliminations for the fellowship when she was a job applicant at the beginning of Season Four.

Though Dr. Hadley maintains a general refusal to discuss personal matters in most situations, it was confirmed that she was bisexual. Thirteen suffered from a genetic condition called Huntington's Chorea, a recurring plot during her tenure on the show. Her mother and brother both died from the illness (with Thirteen respecting her brother's wishes by euthanizing him) and Thirteen generally showed she was scared about losing control of her body, but she didn't allow it to hold her back.

She was portrayed by actress Olivia Wilde.

Personality
Thirteen is level headed, bright, enthusiastic and generally not afraid to speak up when she thinks she is right. She has good relationships with patients and it is shown she isn't as judgmental as her colleagues when it comes to drug-using patients. This could be attributed to her own history of drug use. She has deliberately kept the details of her life guarded, preferring to go by her assigned applicant number, 13, even after she was hired. Foreman believes that this is because she is bisexual and wants to keep her private life private.

She arguably possesses greater street smarts than any of the other characters. In the episode Joy, she correctly identified a female drug dealer who met up with the patient, while Taub mistook the same woman for a prostitute. In addition, she was able to distinguish unadulterated cocaine from that mixed with impurities and was also aware the dealer kept both pure cocaine (for new customers) and impure cocaine (for addicts) and asked for the impure sample for testing.

In episode The Down Low, when Thirteen and drug dealer Eddie were cornered by gangsters, she easily fell into the role of a prostitute, thereby preventing Eddie's associate from realizing he had brought a doctor to where their drugs were stashed. She also appears well able to defend herself, as when a patient grabbed her in Adverse Events, she not only escaped his grip but did so by breaking his nose.

When she was younger, however, Thirteen appears to have been more vulnerable. In Private Lives, she admitted that at the age of 17, she fell in love for the first time with a man of 30 who was merely manipulating her. Her tough persona might also mask a more sensitive nature, as her encounter with the patient in Mirror Mirror implies she is often in a state of fear and anxiety.
