Thank you for the lead-in, Mr. DM
After the guard(s) leave, Al'quien makes a rude gesture at their departing backs and creeps forward (with his spoon, they forgot to take it. HEHE) to peer around either way, making sure there's no guards near his cell. Once he's sure, He'll move to the hole, and see if he can lift the stone. (Careful not to drop it) He then pulls the paper out to examine it quietly, keeping an eye/ear out for guards.
