Kumar sets Marika up for the nerve test, telling her to let him know as soon as she starts to feel uncomfortable as he puts bands around her hands and feet. Marika is only worried that a medical test means there's something wrong with her, but Kumar tries to ease her fears by saying that this test will help Nick get better. The better she does, he says, the better he'll be. Poorly explained and possibly inaccurate. Maybe it's a good thing that we don't see much of Kumar after all. With that, Kumar and the wife retire to the booth and Kumar starts cranking up the heat on the bands. Wife would rather chat about how she's having a hard time with the things her husband has said to her. She knows he can't help saying them, but that doesn't change the fact that he thinks them. You know, Kumar could say here that they don't know if Nick even thinks the things he's saying because of the brain damage to make the wife feel better but instead he wonders why Marika hasn't felt the heat yet. Could she be sick too? No, she just didn't want to say anything until the heat was so unbearable that she had no choice but to scream in pain. Kumar whips the nerve things off her hands and feet, which are now burnt, and asks why she didn't say anything when she started to feel it. Marika says she wanted to hold out as long as possible since Kumar said the better she did, the better her dad would be. Wife glares at an apologetic Kumar, but it's kind of her fault, too. She should have known that Kumar's explanation was sucky and Marika might not get it, but instead she was too busy thinking about herself.
Taub's stuck with Nick for hours on end as he performs the glucose tolerance test. Nick complains that he's hungry, having probably exhausted any and all negative comments about Taub's appearance at this point. He then asks Taub if he can make sure that Hadley isn't at his bedside any more, because he doesn't want to share his "rich imaginative life" with her. Hadley making out with Cuddy on a bed with a mirror on the ceiling? That's not all that creative, Nick. Stop patting yourself on the back. Taub says sexual thoughts are normal, as if that's supposed to make Nick feel better. The thoughts are normal. Saying them out loud kind of isn't. Nick says he'd rather be judged by his actions than his thoughts, and when he says he's never cheated on his wife, Taub makes an "I DID!!!" face. Nick picks up on it, much to Taub's surprise, and says Taub is a creep. Taub runs away.
