Thirteen is too young to gain eight years of memories that might come to pass--especially when you don't even know what to do with yourself in the present. But when the future is that bloody and dark, do you have any choice but to try to change it? He remembers the absolute agony of the doctors trying to save him, which finally sent him into blissful unconsciousness— —except he doesn’t remember any of that.
