Let's think about this:
You are all low on hit points, right? Simply tell him, the PC, as sweetly as possible, "Dear Binky, my sweet fellow, if you should touch, push, pull, fold, spindle or mutilate ANYTHING in this room while we rest, I will BEAT THE LIVING **** out of you long before whatever fell trap or creature gets to do us in. Have I made myself clear?" Then promptly tell the DM that you have both eyes on him, and a readied action to do exactly that should he attempt to touch anything except his own equipment.
It worked for me!
