Lucky Thirteen (House) - Plot

Plot

Spencer (Angela Gots), a woman with whom Thirteen is having a one-night stand, has a seizure at Thirteen's apartment. Thirteen accompanies her to Princeton-Plainsboro Teaching Hospital where House and the team take the case. House remains more concerned with Thirteen's confirmed bisexuality and finds the situation a good opportunity to delve into her personal life. House and Foreman go to Thirteen's apartment to search for drugs that might have caused Spencer's illness.

Thirteen suspects that the woman's illness is related to her drug use, but she then finds out that the woman has a long medical history and has seen several doctors over the past few years, along with the fact that she only slept with Thirteen to get to House, who would not accept her as a patient after she had been trying to see him for over a year. Foreman tells Thirteen what he found at her house. It's a slip of paper that shows Thirteen's Huntington's progressing faster than she thought it was. He also confronts her about her current hard-partying lifestyle, warning her that it is sending her life and job into a downward spiral.

After Cuddy catches Thirteen with a terrible hangover, she wants her to do a drug test. After preventing this, House fires Thirteen for missing the differential diagnoses. Despite being technically unemployed and off the case, Thirteen remains at the hospital. When it is determined Spencer's illness, Lymphangioleiomyomatosis, is fatal, Thirteen volunteers to tell her, saying that no one should hear such a death sentence from the cold, uncaring House. Later, House has a brainstorm and asks Thirteen if Spencer cried when she heard the bad news. Thirteen says no. House then determines the true cause of the girl's illness based upon her inability to produce tears, a symptom of her illness, candidiasis (a fungal infection) secondary to Sjögren's syndrome, an autoimmune disorder in which immune cells destroy exocrine glands that produce tears and saliva.

When Thirteen is able to prove her loyalties at the end of the episode House rehires her, although Thirteen discovers that firing her was merely a game of House's to see if she would grow close with the patient. At the end of the episode, Thirteen continues with her risky habits, partying with another woman.

It is also revealed that Cuddy is adopting a baby, after House follows Wilson to a baby store and sees her there. When House learns that Cuddy had Wilson be her character reference for the adoption agency, House refuses to congratulate her, using for the second time in the episode, "If you're happy, I'm..." and then walking away.
