Yussa looks at his notes where they clearly cut off - not mid-sentence, thankfully, but halfway down a page. He frowns in thought, trying to remember what he'd been doing, exactly, when everything went wrong.

"I think the former, and in the process did the latter," he muses as he looks over some of the samples still out on the table. He finds the offending component to bring it closer - some plant that had been growing in the Silted Vale. "But what did it combine with...?"

He asks the question mostly to himself, scanning the table again to try to sort out what else he might have touched.
