Re: Jon Snow -- Beware of Spoilers
I just had one more addition to Needle's theory. It was much discussed that Jon was acting very un-jonlike during this chapter in aDwD. This could be because he was warging into another body (the ice body if Needle is correct) and influenced by the feelings of that person (reanimated corpse). We see Varamyr discuss the kinds of animals that skinchangers "shouldn't" become because of how it changed their perspective. Perhaps Jon was acting in this way because of the influence of the real owner of the body he was occupying.
