Nate tried to ignore William's stagger. What the fuck had happened over the weekend? Especially considering the way Gerard had looked when he'd been interrogating Nate about the wand-splosion. Was there something dangerous about wandcores? Huh.
He reminded himself that it was none of his business. It was difficult, since he tended to consider everything at Hogwarts his business, but he managed to tamp down his need to subtly glean information. He would just save his questions for later; magical theory and wand theory were pretty closely related, after all.
The bibliography spell would probably be useful for that — and damn, Nate was impressed. He supposed he'd known vaguely that there was such a thing as library magic, but in his rare jaunts into the library, Madam Pince had never made it seem terribly interesting.
"No!" He hastened to reassure William, still staring at the glow. "Nothing's been postponed. It's not a project. Really, really not a project. It's just, uh. A thing. A not-important thing."
