Ex continues that Wilson was so nice and considerate and such a "knight in shining armor" to her that she couldn't resist him. By the time Wilson wasn't there for her anymore, it was too late and she was hooked. House asks if she might not have fallen into the Wilson trap if she had had sex with him before she fell in love with him. Ex says she would have, then gets a little TMI and says sex with Wilson was "fantastic." "Nobody works harder to give a woman what she wants," she explains. Wait, are we talking about tampons again?

Our patient is still coughing. She denies that the crack pipe is hers, but does admit to taking a few hits off of it. "What's wrong with having a little fun?" she asks. Um, what's wrong is that IT'S CRACK. Lupe senses that Foreman doesn't like her. He says that honestly, she doesn't stick out enough in his mind one way or the other. Lupe gets all hot and bothered and says she can tell that Foreman thinks he's better than she is because he got out of the projects and became a doctor and she didn't. How can she tell that? Because he's black? It's not like he's wearing a neon sign that says "Ask Me About My Rough Upbringing In The Ghetto." Lupe says that the only difference between them is that she made bad decisions and he made good ones. Well, duh. That's the difference between Hitler and Mother Theresa too, if you want to break it down. Foreman shows that he's exactly the smug, superior prick Lupe thinks he is when he tells her to stop having fun with crack pipes and start going back to school. Lupe whines that "the system" isn't set up for "people like [her]." What system? The one that gives out tons of financial aid and loans? Yeah, you've got to pay those loans back, and it's not easy, and it sucks to be in debt for years and years, but that's what you have to do. Foreman notices her eyeballs looking yellow.

Lupe's liver will fail in two days. Foreman says they're not looking at an autoimmune disease after all, since the steroids aren't working. Cameron insists that it is an autoimmune disease, since the white blood cells are attacking Lupe's body and that's the way it goes in CamLand. Foreman thinks it's a rare and aggressive form of cancer called lymphomatoid granulomatosis, which Foreman says fits all the symptoms. Lupe's only chance is total body radiation right now. Doing the tests to confirm the diagnosis will take longer than she has to live, of course. Chase and Cameron protest, but Foreman presents the case to House that if he's wrong and Lupe does have an autoimmune disorder, total body radiation will suppress her immune system just like those steroids would. So either way, Lupe will win. Unless,of course, it's not an autoimmune disease or cancer. But House goes for Foreman's reasoning and even volunteers to get Lupe's consent when Foreman says he can't do it because she's kinda pissed at him. Chase doubts that House will rub her the right way any better, but House doesn't care how she feels about him; he's only interested in the reasons why she doesn't like Foreman.
