I don''t think we'll see a scar. or anything like that.
The problem i personally think we'll face is credibility of re-attachment.
If you look at the spinal cord, it has serious damage. It has been ripped out violently from its body, there has to be damage.
damage inside, which you can't really reach. how is it able to connect? i don't believe for a second in bs like 'healing' capabilities.
that would mean david will be slightly handicapped at least, unless he has figured out another way of 'fixing himself'.
the person standing with the eggs supposedly is david - im not sure about that though, but lets assume that - and physically, he looks
in perfect shape. i wonder though, could he 'invite' walter over and transfer his mind?
