Well now that we have the undying running around, I have to ask the gory questions:

Will a body without a head continue to act as though it can see, hear, etc,or will it be erratic from the loss of its senses? Will severed limbs move independently or stop moving once separated from the body? Will debilitating injuries (severed hamstring, broken knee, etc) affect movement or will they just power through it? Will they be able to reattach lost limbs?

...how far into Deadite territory are we going here, is what I'm asking.
