House tells LL that he probably has an adrenal gland tumor, and that he'll need an MRI to see where it is. House claims that MRIs are "painless for most people," unless they're House's patients. In LL's case, it's because his prison tattoos were make with inks chock full of heavy metals. MRIs are magnets. Unless the MRI is just Magneto lying on top of a plastic tube, I find it hard to believe that even metal-laden inks could have that much of an effect. Then again, LL has been proven to have a low threshold for pain; maybe his screaming and thrashing around is just because he's a wimp. House, Foreman, and Chase observe from a booth, and I don't know how they can get any results with the patient moving like that. House calls LL a "big baby," and then he finds the tumor. "There's Waldo!" he says. LL begs them to turn off the MRI. House tells them to keep him in there until they see it, too. Uh...I'm pretty sure that "do no harm" oath applies this time, House.
Night falls on the hospital. Foreman enters House's office to report that LL's tumor has been removed and everything's fine. House says that LL can go back to Death Row. Foreman has a problem with this; after all, the tumor was what gave LL those "rage attacks" that made him kill. House says that they'll put the tumor on the witness stand. Foreman says they can put themselves there for LL's appeal. House accuses Foreman of being a hypocrite; Foreman wouldn't consider LL's upbringing as a reason why he became a murderer, but he's all set to write his murders off for biological reasons. Foreman says that upbringing and biology are totally different. House says that Foreman had to overcome one of them, so he's only half an expert. Plenty of adrenal gland tumor sufferers have become successful, contributing members of society who didn't kill anyone. It's not really fair to them to let LL use it as an excuse. "You want him to be executed?" Foreman asks. "That's not what I'm saying," House says. But he won't offer an opinion one way or the other. Foreman says that he's going to testify at the appeal. "You'll do what you think is right -- on your own time," House says, but I think he respects Foreman for that. And Foreman respects House.
