Will and Toni are walking through the police station when he asks if she has a take on the beating case. She says she's working it out right alongside him. He asks her about Koczara. She says he's not her favourite: "The odd offensive remark now and then when he's been drinking. Across the board, though, he doesn't single out any particular brand." Will, noticing Toni's eyes are all over the place, remarks, "And yet, you can't really look at me when you say that." At that, she looks at him. He says, "I could benefit from your candour, Detective. And don't worry about the blue wall. Everything stays right here." She looks hesitant, but finally says, "Guy's a racist. In my opinion, he was looking for an excuse." Some cop comes out of a room not far from them, and she looks uncomfortable. After the cop walks away, she says that Raymond Hartzel's been released and will be brought in for questioning. She thinks Will should be present at the interview, and Will agrees.

AP Chem. Ms. Lischak asks for two general categories of energy, and then pretends like she might ask anyone in the class, but ends up asking Luke, who promptly states, "Kinetic and potential." Ms. Lischak: "With the sexier of the two being...?" Luke: "Potential, for its chemical bonds being the forces that hold atoms together." I notice Glenys is gone from his and Friedman's desk, and the original male nerd seems to be back in the saddle. Or whatever chemists ride in. The teacher rambles on about energy while Joan whispers to Grace, who's gently tapping her own chin with a pair of those tongs you use to pick up hot beakers, "This kid is totally obsessed with death. Isn't that strange?" Grace mutters, "No stranger than being obsessed with this stuff...like Atom Boy." Luke turns and says, "I heard that!" He pretends to be annoyed, but is obviously secretly delighted to register on Grace's radar. Grace loves Lu-u-u-ke! Grace loves Lu-u-u-ke! Yeah, I'm five. But it's so obvious. Now she has a cute little nickname for him. Joan says the kid has asthma or something: "But it's not like he's gonna die from it." Adam suggests, "Then maybe he knows someone who's dead." Joan turns to him and sniffs, "You can't know dead people." Adam: "Forget I attempted to contribute." He turns his face away and rests it on his other hand. Joan asks, "Seriously, what is wrong with you?" Grace: "He doesn't like November." Adam looks much sadder than usual.
