Chase finds Cameron in the lab looking at Dibala's biopsy. He wants to talk to her about her "joking" about letting Dibala be assassinated. Cameron insists that that was no joke. "You can't want to kill anyone. Especially not your own patient," Chase insists. Cameron doesn't think it's that simple, but Chase says you'd have to be a psychopath to kill someone without having "some sort of breakdown." Cameron thinks it would be justified in this case, but Chase says that doesn't matter. Cameron says she's not going to kill Dibala, but she wouldn't be all that broken up if he died, either. And anyway, the biopsy is negative for lymphoma.

Murphy comes home to find House waiting for him outside his apartment, looking very smug indeed. House says he knows Murphy's dirty little secret, thanks to a look at his proudly-displayed flag and a chat he apparently had with the housekeeper afterwards. I hope that chat was good for her, because she is so fired now. Murphy is definitely Canadian, and House knows that Canada didn't send troops to Vietnam. Outraged rather than busted, Murphy quickly tells House that he's going to jail for breaking into his apartment, to which House says he'll join Murphy there, because pretending to be a war hero is against the law. Is it really? Even if it's just so you can get away with being an asshole to your neighbors? As it happens, though, Murphy did go to Vietnam from Canada after all: they sent troops over to reinforce the 1973 peace accords. That was where Murphy tried to save a boy who stepped on a landmine. He was not successful in this endeavor, and for thirty-six years since then, his phantom hand still feels like it's closed tightly and painfully around the boy's arm. "Oh," House says. Yeah. OOPS. House is lucky he wasn't punched in the face by an arm-hook.
