House wants to do a liver biopsy before they treat Joey for hepatitis. Chase wants to do it now so that Joey will be healthier sooner -- earning him, House suspects, a gold star from Cuddy. Chase asks House if he's putting off the hep treatments to prevent any of them from getting gold stars, and House says that he can go ahead and start the hepatitis treatment right now, then. He asks for a biopsy of the liver, and Chase and Cameron are dismissed. Foreman is asked to stay behind.
Foreman and House move to House's office, where House says he's kicking Foreman off the case. Foreman is understandably confused. House explains that someone told on him to Vogler about how he lied to the transplant committee. Foreman laughs that House thinks it was Foreman, and House says that Foreman's actually the only person he knows didn't do it, because Foreman is "too careful" for that. He wants everyone in the world to think he thinks it was Foreman, thereby causing the true culprit to let his guard down so that House can catch him. All of this paranoia and secret plotting is kind of ridiculous, but not as much as the fact that Vogler's chairman of the board position seems to give him unlimited power.
Chase finishes an ultrasound of Joey's liver and tells the brothers that Joey has hepatitis C. Bill asks Chase how that happened, and Chase says it's usually transmitted through an "exchange of bodily fluids," like sex or drugs. Bill doesn't like either of those options, and gets all up in Chase's face. Chase doesn't know enough about American culture to realize that you shouldn't go against a mobster's commands, and maintains that Joey has hepatitis C and that they're going to treat him for it. Bill gives Chase one of the hardest bitch slaps I've ever seen in my life, and I have seen a lot of bitch slaps. Chase's hair flops all over the place from the impact and he tries not to cry as Bill orders him not to treat his brother for hepatitis C, which he certainly does not have. Chase just stands there and takes it. His wimpiness makes him less attractive to me. That, and his hair.
