The problem, as Foreman points out, is what to tell Dad, as the current plan more or less boils down to "we think he has lupus, so we're treating him for Hep E, and if he does have Hep E, the solumedrol will actually make him worse." Which sort of makes no sense, so they'll have to fudge it -- well, outright lie, really, which House tells Cameron to do, because Dad trusts her. House heads out of the room, looking at least a little ashamed of himself, but it's hard to tell whether it's because he told Cameron to compromise her ethics, or because it's not as snazzy a plan as one he'd come up with at full strength. Cameron and Foreman exchange a "what's with Dr. Kookoopants?" look.
Cut to the hall, Cameron bitching that "this is a mistake" and Foreman correcting her that "this is a lawsuit." Chase defends House, saying that Hep E is possible and that House "always pulls these stunts" and they usually work, but Foreman says House is delaying treatment for a long shot that even House himself doesn't think will work. Cameron doesn't want to lie; Foreman tells her pointedly, "Then don't." "And get fired?" Chase joins the viewing audience in pointing out that House wouldn't fire her: "He loves you." As she gets into the elevator, Cameron doesn't know what to do: "The kid needs treatment." "Then treat him for lupus," Foreman intenses. "That will get you fired," Chase says. Cameron waits a beat before half-asking Foreman, "You really think House is losing it." "Yep," Foreman duhs, and walks off. Chase gives him a "what's your problem" side-eye and insists to Cameron, "He's fine. He knows what he's doing," and goes on his way. Cameron stands in the elevator all conflicted for a minute, then rolls her eyes and hits "door close."
