Later, at Harrison’s locker, Sam comes up behind him, saying, “Hello stranger.” She points out that they haven’t spoken for a month, and that she misses him. Harrison tells her to “make like an egg and scramble.” Whatever that means. I thought the proper saying was “make like an egg and beat it.” Or maybe that was the point of the joke? Sam tells him to stop being childish. They’ve been friends for years and they are going to have to “salvage” their relationship. Harrison tells her she’s on her own, and she should go be with her boyfriend George. Sam keeps trying to break through to him, but their conversation is interrupted by Chem and an officious-looking blonde woman in a suit. They are both wearing those aqua-colored face masks to prevent the spread of germs. Apparently, Harrison has picked up Rift Valley Fever in Yemen. Nosebleeds are the first symptom and Chem, upon seeing Harrison’s pop quiz in which he mentioned being in Yemen, notified the CDC, who sent the officious blonde woman. She introduces himself as Dr. Jeanne Salk. Hee hee, geddit? Jonas Salk created the polio vaccine? CDC? A little “Great Biologists of the Twentieth Century” humor? Anyway, they cuff Sam and Harrison and take them in to be quarantined. Harrison tries to explain that his nosebleeds were a result of dryness caused by the central air system at school. “He’s hallucinating,” says Chem to Dr. Salk. “Step two of the deadly fever,” says Dr. Salk, who orders a lockdown of Kennedy High to contain the disease. The thing that doesn’t make sense is that, if Chem and Dr. Salk are in contact with Sam and Harrison, shouldn’t they be quarantined too? I mean, obviously it’s airborne if they think Sam got it from just talking to Harrison. Not to mention the fact that those face masks do nada. Whatever. It’s Popular.
