"His personality issues?" Enid asks, ever so hopeful. Sorry, House says, those have nothing to do with iron and everything to do with Nate being a horrible person. Meanwhile, who was the asshole lab person who didn't test the iron levels in Nate's body? Wouldn't someone do that as part of an exhaustive look at what could be going on there? I don't think it's standard procedure, but you'd think that with Nate on death's door for unknown reasons, they would have done every blood test in the book trying to figure out what was wrong with him. Anyway, House slices Nate's hand open and lets him bleed the iron away, meaning that, in the end, Nate may have gone "medieval" on the hot chess guy, but it's medieval medicine that will save him. It also makes Nate like the only person medieval "medicine" has ever saved. House says that Nate will need dialysis for his kidneys and regular blood drainings for the rest of his life, but at least now that life will be a long one. "My condolences," he says to Enid, who cries, although I'm not sure if that's from joy or sadness. Just to get the last word, House leans over and tells Nate how he would have gotten out of his little chess trap and won the game after all, but Nate says he knew about that out all along. "I was bluffing," he says, "and that's why you lost." "Jerk," House mutters, while the nurse he called in like fifteen minutes ago finally moseys into the room to take care of Nate's bleeding. I guess the nursing staff likes Nate as much as everyone else does.

House makes one last stop before he leaves for the night: the lab, where Foreman is hard at work. House hesitates, appearing to prepare himself to be not evil and ask Foreman to stay. But then, instead, he asks Foreman if he's looking for amyloidosis in Nate's biopsy. "Yeah. Still nothing," Foreman says, refusing to learn even after House so much as told him that he doesn't want an employee who blindly follows his orders without challenging them. So now, House has two choices here: he can tell Foreman he wants him to stay, or tell Foreman he wants him to quit. Instead, he chooses a Third Way and orders Foreman to run the test again. Foreman will stay up all night doing this unnecessary test without even realizing that he's taken -- and failed -- the only test that mattered.
