Lemm is kind of surprised to be waved at. Maybe he shouldn't be. She's conscious (...somewhat?) and that's a fairly ordinary reaction to have to seeing people.

He hesitantly waves back, or rather raises a hand at her in a more reserved way and offers another little nod.

"...Hi," he offers as a verbal component, not quite convinced she's seeing him properly. He's very quiet about it, and feels like that was simultaneously too much and somehow not enough of an effort.

His attention snaps gratefully back to the Knight's words when they finish writing, the distraction wholly welcome.

"Aye. I'll keep an eye out for any that didn't take in the damp. I've been through the same thing." They know. They've seen where he sleeps. Isn't that a thought. "S'there anything else you'd want to put in here? Might be able to streamline the search a bit."
