"Office Politics" is the sixth episode of the seventh season of the American medical drama House. It aired on November 8, 2010. It is also the first episode to feature Amber Tamblyn as Martha Masters, as a replacement of Thirteen (Olivia Wilde). Plot A New Jersey senator Hal Andersons campaign manager Joe Dugan (played by Jack Coleman) falls ill with liver failure and temporary paralysis. Meanwhile, Cuddy pressures House to add a female doctor to his team but eventually tells him that she has chosen for him: a third-year med student named Martha Masters, who is a genius. Taub appears to have a problem with Masters, which Foreman and Chase try to figure out. Throughout the episode, House keeps firing and rehiring Masters, rehiring her whenever he needs her for an idea, and firing her again as soon as he's done talking to her. Masters suggests a neuroendocrine tumor, and the team also considers DIC. The team give Joe an MRI to look for a tumor, but don't find one. Taub runs Joe's blood, which also comes back normal. Looking at the senator on TV delivering a speech, House suspects the senator has Hepatitis C, and thinks that he's had sex with Joe, and thinks Joe has Hepatitis C as well. He gives Joe interferon, but Joe doesn't get better. Masters notes that a German research study has shown that 15% of people with Hepatitis C who have been injected with Hepatitis A got better. When Cuddy says trying this exposes the hospital to liability, Masters tells her that she's being a coward. Foreman and Chase eventually find out that Taub dislikes her because he interviewed her for Hopkins Med School for an hour and she didn't remember him, even though she remembered the 20th decimal place of Euler's number. At the end of the episode, Taub learns the truth about Masters. She did remember him but felt awkward reminding him, and he mumbles "Is this Grandma's tea cosy?" A reference to an earlier conversation Masters had with House. House takes the senator's blood and runs it under Joe's name to get Cuddy to approve on his decision, despite Wilson's warnings that lying to her would be wrong now that they are involved. House also hires Masters in the end, saying she had him when she called Cuddy a coward. The show ends with Cuddy going to the nurses station
