Natalie is negative for mold allergy, so that diagnosis is wrong. Kumar reassures Natalie that they'll figure out what's wrong with her sooner or later, and that if she doesn't want to talk about the bullying at school with her parents, there are other people she can talk to. Natalie cuts him off and says she'll be fine. Kumar notes her positive attitude, and Natalie says she's doing her homework, which cheers her up because she's "such a dork." Homework used to cheer me up, too, but that was only when it was math homework and the answers were in the back of the book. Apparently, Simon just brought it to her, which Kumar finds odd enough to page security. Yeah. Like they're going to do anything.
Apparently, PPTH's crack security squad is able to stop people. Children, but still. The new team Cuddy hired after firing everyone after the hostage crisis seems to be working out so far! They stop Simon on the way out, and Kumar confronts him. Simon says he was just bringing her homework, but Kumar doesn't think so. He says Simon wasn't being compassionate when he bullied her and supplied those drugs, so he doubts he is now. Kumar suspects that guilt is motivating Simon instead, and demands to know what Simon feels guilty for. Simon says nothing, and Kumar threatens to turn his mushrooms in to the cops and calls him a "slimy little jerk." Why haven't they turned the shrooms over already? Those kids should be in jail for drugging their classmate! Apparently they haven't even gotten suspended from school for it. Taub pulls Kumar away and accuses him of taking out his own childhood pain of being bullied out on Simon. Kumar denies being bullied as a child, but Taub is pretty sure that "the Indian foster kid whose parents were shot right in front of him" got plenty of shit. Really? I'm pretty sure kids stay away from making fun of other kids whose parents were tragically killed. Kids whose parents are morbidly obese and collect so much trash that it fills the trunk and backseat of the station wagon, perhaps. But those parents are alive and stuff. Kumar cools off and turns back to Simon. Simon says Kumar doesn't understand -- he used to be friends with Natalie until she became unpopular and he had to distance himself from her so he wouldn't be unpopular, too. By the way, Natalie used to be a big drinker, thanks to Simon using his brother's ID to buy a big supply to sell to his classmates. Simon is hooked UP, you guys. Does he really think talking to Natalie will make him unpopular when he can supply everyone with alcohol and drugs? Please. He says Natalie used to buy a couple bottles of vodka A WEEK. She only stopped buying from him when she got her own ID.
