House returns home to find Wilson eating Chicken Florentine sans garlic, watching the TV at a very low volume, and not wearing shoes. Wilson thinks he can distract House from his suspicions with a reference to True Blood, which they no doubt watch together every Sunday night. It doesn't work: House puts everything together and comes up with a whiny downstairs neighbor, a hypothesis he proves by banging his cane on the floor a few times and hearing the neighbor angrily rap on a pipe in return. Wilson admits that his neighbor, Murphy, isn't a fan of the "extra noise" and "cooking smells" associated with living below House, and Wilson doesn't want to piss him off further because the guy is on the condo board and Wilson is hoping for a renovated back garden. And apparently a renovated back garden is worth the loss of self-respect that comes from kowtowing to an unreasonable jerk. Although I guess that's nothing new for Wilson. He is friends with House, after all. House assures Wilson that he now knows some useful coping skills he can employ while talking to Murphy, but Wilson says Murphy is a decorated war hero who lost an arm in Vietnam and so demands everyone's respect despite being a giant asshole. House agrees to stay out of the man's way. Then he gets a call from Cameron to tell him that Dibala is currently having a heart attack. She talks to House on the cell phone casually while Chase does everything to save Dibala. Foreman is nowhere to be found. They probably didn't even call him about this. I wouldn't, either.
Upon entering the meeting room the next day, House immediately calls out his diagnosis of Lassa fever, figuring that if Foreman was mad at him for holding the diagnosis back last time, this should make him happy. No one is buying that House is concerned about Foreman's happiness. Foreman rejects the diagnosis, saying that Lassa is not present in Dibala's always-unnamed country. House raises his hand like that annoying know-it-all kid in class, and Foreman pointedly ignores him until Cameron just points at House, giving him no choice but to call on him. "Don't people sometimes travel?" House asks with fake innocence. I'll bet the expression on his face as he said this was awesome, too, but I can't see it because everything on either side of the screen has been cut off for a second week in a row. Is this my TV's fault or does Fox assume we all have widescreen sets now or what? Foreman turns his suggestion down, saying that none of the three countries Dibala visited in the past two years had Lassa, either. House points out that one visit was to an African Union conference, which would therefore expose him to someone from a country that did, in fact, have Lassa fever. It's a stretch, but Foreman has no choice but to agree with the diagnosis, although he could at least try to test Dibala for it first before treating him. But he doesn't. House cheerfully says it's great to have the old team back. Chase just raises a coffee mug in agreement, because this is a lot easier than all that surgery he was doing before.
