Nate was proud that he only paused for about a second before digging in his bag for parchment and a self-inking quill. His hand hovered over his notebook for a moment, but he eventually decided against it. William looked caught in his own thoughts — his own, incredibly depressing thoughts, judging by his face — but even so, he would probably still notice Nate flipping to a specific section. If he was really observant, he might even wonder why the page had "GABE/WILLIAM, CONT." at the top.
Parchment was safer. "Obfirmo, non-toxic, liquid, ink," he murmured, scrawling it down. "Tutaminis, injection, lethal." He took a moment to review that. A warding solution and — didn't tutaminis have something to do with protection? Gerard would know. And what on earth was this about toxicity? "You want... what, stuff like this that can be used on people? Isn't obfirmo usually for doorways and foundations?"
And it was important enough that he was going to (indirectly) ask Gabe about it, despite avoiding him? Nate scribbled a few extra notes down.
