They've decided to put Emmy in a cold weather situation by forcing her to work out in the freaking morgue, with dead bodies all around her. Really? That's the best they could do? That's not creepy for the patient or anything. But Emmy isn't bothered, as the chance to do some hand-pedaling (running on a treadmill is out since her ankle is broken) is a more than welcome one for the fitness freak. Unfortunately, she's also subjected to questioning from Taub, who insists on not believing that she doesn't indulge in unhealthy foods or bad habits. Just because you cheat, Taub, doesn't mean everyone else does. Leave her alone. With Taub distracted, Kumar is left to notice that Emmy isn't looking too good. She says she's fine, but her face turns red and she suddenly passes out. Not only that, but she has no pulse. "This isn't asthma!" Taub says helpfully.
Hadley's doing some motor function tests. But they're boring, so she makes small talk with Foreman at the same time. She asks if there are a lot of people in the trial. Foreman says yes, then tells her to try the test again -- this time without talking. Hadley starts again. Two seconds later: "I shouldn't be here." I'll say! She can't even follow simple instructions. Hadley thinks it's unfair that she only got this spot because she knows the guy running the trial. Foreman says she got the spot because she has Huntington's. Then he makes her do the test again -- without talking. Two and a half seconds later, Hadley is saying that this is a trial for people with symptoms, which she doesn't have. "Shut up," Foreman says. He then reveals that she didn't do so well on the test, which means her nerves have started degenerating. I'll say! The following commands nerve is, like, totally gone. Hadley's reaction to this devastatingly terrible news is a blank stare.
Oh, insult to injury! Not only is Cuddy in House's office, but she's also playing with his giant ball, and doing it badly, clumsily bouncing it on his desk with no rhythm. House enters the office and says they'll have to share the desk. Cuddy says that's fine and starts rearranging the desk accordingly. That wasn't the reaction House was expecting. Taub and Kumar come running into the room to report that Emmy's heart stopped during the test, but they were able to shock it back to life. Kumar says the test didn't set the heart stoppage off, and EKG results were normal. So now they have a patient with lung and heart problems that have nothing to do with her lungs or heart. Kumar guesses a carcinoid tumor. House tells them to find it and get rid of it. He then returns to his showdown with Cuddy.
