Hello again hello.

So, the hand. Because we've had it find rings there's talk that it can *see*, and the question has been brought up whether or not it can hear too. Can they hand see/hear or is it just blindly sensing rings/throats/other hands to hold? Can we communicate with it? Say we tried to figure out a form of answering like tapping and the like, could the hand reply? Would it have anything to give us or is it uninterested in letting us know who it belongs to
