Is that an un-spoiler?
Putting a fan rumor to rest?
Either way, good to have a definitive answer to that one.
Also, people saying people are dead in AsoIaF is definitely not grounds for them being dead. And if, so, if he was considered "dead" couldn't he still be all white and walkery?
Are white walkers zombies? Dead people risen? I don't have a clear idea on that theory.
I always thought CH was an ancestor of the Starks, like an old Brandon or something. Or maybe even a descendant of the original white walker, like maybe Bran's white walker family equivalent. A white walker son that doesn't want to murder everyone.
