In the meeting room, the Cottages eat lunch and talk about how mercury poisoning has been ruled out. Yeah, I already knew that. Catch up, you three. Chase suggests hemolytic uremic syndrome, which would have been my second guess, but Foreman nixes that as well. Without looking up from his unreadable printouts of whatever he pulled off of Alice's typewriter ribbon, House figures out that the seizures happen when Alice is upset, so they could be caused by elevated adrenaline. "A pheochromocytoma," Taub realizes, snatching the word from the tip of my tongue. House orders an MRI to find it, and when they go back to their food instead of immediately jumping up, he sweeps all of their takeout containers into the trash can, which he even made Chase hold. "I meant now," he explains. Which they should have known already. I mean, really.
Taub and Chase roll Alice's gurney into the MRI (of DOOOOOM, right?) room, ignoring her complaints about claustrophobia. But they can't ignore it when she suddenly gets a "leg cramp" that quickly turns into agonizing pain, and then into a visibly sizzling line of spots on her shin. While she screams, Foreman rushes in, telling them to get her out of there because she has metal in her leg. Which sparks like a fork in a microwave while Alice continues to shriek like she's had a white-hot iron buried in her leg, and the Cottages stand there staring at each other in horror. This is why they aren't emergency physicians.
