The initial response of: "What?" Before he realized just what it was Charles had dropped to him was quickly followed by: "Charles that's brilliant!" Tone delighted and fond in a way he probably didn't fully realize, but it was a tone -and a statement- that was definitely sincere.

He checked over the pictures, shuffling them into an order he could use -he'd copy the runes down larger once they returned to the office, so they could actually be seen at something close to full size, and he'd even do what he could to recreate the placement and the through-lines of the circle as well, just to see if he could determine what it had originally been for, because it was entirely possible that using the trap for the poltergeist on top of it was what had caused the problem in the first place, if the circle itself wasn't the issue.

He tucked the pictures into the pocket with his notebook to make sure they were secure, "I've managed as much first aid as I'm able, I'll need assistance covering my shoulder before we start back to the office." He did know better than to leave it exposed, especially as they were going to be walking for a while, and that was something he already wasn't looking forward to with the way his chest still felt tight and his breathing too shallow.
