Martha follows House into the hallway. She's upset that everyone knew about the fake PET scan except for her, and House says he has to keep things from her because he can't trust her. Duh, Martha. Martha says that even though she knows she would have told Ramon the truth and he'd be dead by now, she still doesn't think it's right to lie ever. "We can't work like this," she says. "I can," House says. Well, what did she expect?
Wilson arrives home to find Sam packing. Yes, she's leaving him. Wilson says they only had one fight and he admitted that he was in the wrong, so why is she leaving him instead of trying to talk things through? But Sam says she can't get over the fact that Wilson thought she lied to him. "I know where this is going, and I don't want to go there again," she says. I'm guessing Cynthia Watros is going to another show and had to be written out ASAP, because this is really abrupt. "You're quitting again," Wilson says; "so I guess you haven't changed that much." Guess not; Sam zips up her suitcase and leaves.
House reports to Cuddy's office, where she congratulates him on both saving his patient and keeping him from suing PPTH. Ramon doesn't have enough money to buy food, but he's not going to sue PPTH for millions of dollars? Okay. And here comes House's apology to Cuddy, generously borrowed from Ramon. He says he has to stop trying to prove his argument that everybody lies and take "a leap of faith." He looks her in the eye and says he'll never lie to her again. Just like Ramon, Cuddy totally falls for it because those are the words she wanted to hear regardless of whether or not they're the truth.
