Kumar and Taub test Jeff for Biana's heart diagnosis (I guess she doesn't have to help since she thought of it?) and wonder what to do about their boss, whose skills they're assuming are failing based on one differential diagnosis session. Kumar says he killed House's gift and he feels awful about it. Good thing CTB is there to freely walk around patient rooms and tell them that House doesn't have syphilis after all. Yes, Wilson betrayed House's trust and told her everything, and now she's telling the Cottages because she hates House. She takes off, and Taub says they're idiots, which is true. "We're not idiots. Positive blood test means positive blood test," Kumar says, still not getting it. "Apparently not," Taub says, which gives Kumar an idea. It's such a good one that he walks right out during the ultrasound.
After the break, Kumar finds House in the hall and they have the following exchange:
Kumar: Patient tested positive for syphilis, right?
House: Is this some sort of recap?
Is that some sort of shout out? I think it is! You know, I've been writing for this site for seven years and this is my first shout out! If it isn't a shout-out, don't tell me, okay? Don't kill my honor of getting a shout-out in an episode all about syphilis.
Back to the show I'm some sort of recapping, Kumar continues that a positive syphilis test means that either the test was wrong (twice) or he gave them someone else's blood. Oh, he's not talking about Jeff now -- he's talking about House. I guess House put his name on a vial of Jeff's blood? House knows he's busted and demands to know who told them. Kumar does not hesitate as he reveals it was CTB, and poor House is so sad that he has officially lost Wilson to the Dark(er) Side. But Kumar's not done yet! He has another option, and this one does apply to Jeff: the patient has a condition that creates a false positive for syphilis. House knows that Kumar is talking about Chagas Disease, a parasite that's rare in America but not in Costa Rica, where Jeff spent some time while he was in the Peace Corps. The disease could have caused encephalitis, making Jeff's brain swell and causing personality changes. Or maybe he's just actually nice. After all, he got Chagas while he was in the Peace Corps., which means he volunteered for them before he got Chagas. But, whatever. I don't care about Jeff or his wife. Kumar continues that now that they've pumped Jeff full of steroids and compromised his immune symptom, the disease really got a chance to get going, causing the liver damage and heart attack. Wow. Way to ruin Jeff's organs, House. Next time you might want to test the guy for Williams and sarcoidosis before you treat him. House realizes that he was so busy playing mind games with his fellows and tug-of-war with CTB that he let Kumar have his end-of-show epiphany. Let's hope that means less fucking around next week and more of what makes this show so great. With a little fucking around thrown in.
