Chase and Foreman perform the biopsy, which gives Chase a chance to tell Foreman about Cameron's little sperm collection. Foreman doesn't understand why Cameron isn't happy with the sperm she's about to marry, and neither does anyone else because this is insane, even for Cameron. Chase says Cameron is hedging her bets so that she'll be able to give birth to one of her husband's children if things don't work out with Chase. "Wow," Foreman says. He does not add "your fiancée is crazy ... it might be time to break things off, hmm?" so clearly he isn't a real friend to Chase. He does say "she married a dying guy. She has issues," although that's kind of rich coming from a guy who is currently dating someone with a terminal illness. He says if Chase forces Cameron to get rid of her Poor Dead Husband's sperm, then the pressure will be on him to make sure they always stay together, because if not, then Cameron will always have him to blame for killing off her potential kids, not to mention all those awesome Octomom endorsement deals and talk show appearances. At this point, Penelope decides that this is all very ridiculous and starts having heart problems to shut everyone up.
After the break, Taub exposits that Chase and Foreman managed to get the liver biopsy despite Penelope's heart issues. It was negative for cancer, and now Penelope's heart rhythm is abnormal. Oops. Foreman would rather know why Wilson is in the meeting room. House lies that Wilson was there just in case the biopsy came back positive for cancer, and Taub says that they can't figure out what's going on with Penelope's heart because its abnormal rhythm makes it impossible to scan. Again, Foreman is more concerned about Wilson, asking if he's been appointed in charge of this case by Cuddy. Obviously, his feathers are all ruffled because he's usually the one who gets to be in charge when Cuddy is mad at House. Meanwhile, CTB is playing with a hallucination scalpel in House's office. Foreman decides that House himself must have put Wilson in the room with them because he can't trust himself for some reason. To prove that's not true (even though it is), House tells Wilson to leave. Nice going, Foreman. Now House still doesn't trust himself and he's been forced to get rid of the one person who knows why and how to deal with it. With Wilson gone, a seat has been left empty for CTB. She sits down and lays her forearm on the table and says that House knows he doesn't have MS, which means it's either mental illness or Vicodin. Either way, CTB says, House won't be able to practice medicine anymore. With that, she cuts a nice, deep gash into her arm with the scalpel. It bleeds all over the place, which is going to be such a bummer for the hallucination janitor.
