I think that's what the person in the other thread meant. The only thing that confuses me is that they realize that the back of the neck seems to be their weakness, but wouldn't a bullet merely go through that region? It probably wouldn't lodge there, so the gun wouldn't do anything (other than hurt a hell of a lot).

I've been wondering if there really actually is a way to kill Claire. It seems that she can only be put down temporarily. Maybe if she were decapitated...
