Well, a miracle has occurred and the Evil Transplant Committee agreed to give Della a lung. I think they booby-trapped it, though, as Foreman reports that the new lung started failing only an hour after the transplant. House says that either Della is rejecting the lung or the lung itself had something wrong with it. If they wrongly assume it's the former and give Della immunosuppressants, then it will make the lung infection worse. If they wrongly assume it's the latter and give Della antibiotics, then she'll reject the new lung that much sooner. House decides to go for the greater of the two evils (or as he puts it, treat "the worst worst first") and start Della on immunosuppressants. If there's no change, hopefully they'll still have enough time to go back and shoot her full of antibiotics. Chase and Foreman head off to do that, but Taub stays behind, saying that he's certain Cuddy will put the kibosh on this course of treatment and House will defer to her, so there's no point in wasting time. House knows this is true, so he sends Taub off to argue for their desired coursed of action, saying he should make a point about how it's easy for Cuddy to always choose the safer course of action when she's sitting on her "ample if well-formed bureaucratic ass."
While Taub is off doing that, a 102-year-old man shuffles into House's office. "Forget the tests," he says. House says his son wouldn't approve of that. At the mention of his son, the old man sighs "I love him but he can't let go." House takes a second to enjoy this before commenting that he'd bet forty dollars the son can totally let go. Old dad continues that he can't go anywhere or do anything without his son acting like he's helpless and senile. "You sure you won't warm up to him over time?" House asks. Old dad ignores him as he pulls a hundred dollar bill out of his pocket and hands it to House, asking him not to bother with the tests and just tell the son that he has to be put in a nursing home. Yeah, because the people there don't treat you like you're helpless or senile or anything. "Private room," old dad adds; "make it a suite." Isn't that adorable? Old dad seems to be confusing nursing homes for hotel rooms. He's going to be in for a shock.
