Wilson goes over the surgery with Tucker, who says that Ashley is more scared of it than he is. "At her age ... she's not supposed to be dealing with issues of life and death," Wilson says. Well, neither is Tucker. He's not 80. People of all ages get cancer. Wilson really wants to know why Tucker left Melissa. Tucker admits that he doesn't know.
House joins Wilson in the OR balcony, if only to be there when Wilson finds out that the surgery was not necessary. Oh, and also to yell at Chase for doing surgery when he's supposed to working for House now. And thirdly, to talk to Wilson about Cuddy moving in with Lucas. House claims that he's fine with Cuddy and Lucas's relationship now even though just last week he was trying to split them up and take Cuddy for himself. With no small amount of wishful thinking, House says the fact that Cuddy is buying a loft suggests to him that their relationship is not actually that serious. He doesn't think Cuddy really wants to "discover her lost city girl youth" and "two bedrooms just reeks of commitment issues." As opposed to the ten bedrooms she has in her current living space? Wilson points out that one of the bedrooms is probably for the kid. "This is classic midlife Cuddy crisis," House tells himself. At this point, Chase interrupts to say that he hasn't found any fungus balls but there is lung damage indicative of PCP pneumonia. And if you're wondering what that means, House explains that PCP pneumonia is only seen in three types of cases: HIV, acquired SCID, or Wilson owes him $100.
