AP Chem. The class is doing various experiments. Luke's team manages to elicit a small explosion with whatever they're doing. At Joan's desk, Grace is playing with a glove blown up like a balloon. Adam is hiding under his hood with his heading resting on his hand and his face turned away from Joan. He looks utterly miserable. Joan asks, like nothing much is wrong, "Okay, Adam, what's the formula for calculating the molar volume of carbon dioxide gas?" He doesn't react or respond at all. Joan says, "Hello, Adam? It's Jane, speaking words of English." Grace asks, "Hey, yo, did your photographic memory run out of film?" Joan: "Adam, I told you I was sorry for trashing your sculpture. I am. I am very, very sorry. You don't know how sorry I am." Grace: "Oh, stop pouting. Get back on the blowtorch and fix the dumb thing." Even though Grace doesn't understand the reasons for Adam's art, I'd have thought she would be somewhat more sympathetic to Adam and a little more pissed at Joan, especially since she was already pissed at Joan when it happened. Price sticks his head in and asks Joan to come with him. Joan loses her grip on the blown-up glove she's been holding onto, and it expels all its air into her face with the requisite farty sound. She gives Adam a sad look before leaving. He hasn't moved a muscle.
