Vincent's little embarrassed distraction has quickly turned into something else entirely, huh-
At first, Vincent is just skimming the pages and flipping through at an even pace, expression neutral with eyes that are flicking over the words. Though, as he keeps turning the pages, he does look just a touch uncomfortable with it, even if you'd have to look closely to tell.
But then he keeps turning, and turning, and turning, and turning, and turning, and suddenly his face darkens quite a bit more obviously. He physically cannot stop turning the pages, pages he already Doesn't want to be reading, let alone flipping through eternally, oh fuck.

"I...It's not letting me..."
Oh thank God, someone was approaching him, and suddenly that notebook is falling from his hands onto the ground, at which point Vincent takes a sharp intake of breath and steps firmly back away from it.

"Y… Yes. I'm ok. Thank you," he says to Ei. Well, he didn't necessarily look it emotionally, but physically that was probably true. Vincent takes a slow breath and flicks his eyes up to the others. "Don't… try t'read that. It wouldn't let me stop, and just… it's the same thing, forever."
Haha-
"What… all needs to be done here before we can leave, do you all think?"
Emily Lewenhock There’s some lab equipment inside, including a sink and a few stacks of empty petri dishes, with traces of something whitish on them.
Looking at that Lab Equipment will help, mayhaps? NOT touching, at least yet. Though he is also looking for any form of safety equipment that might be around while he's at it.
