re: Crackpot ASOIAF Theories SPOILERS

hmm. I think there are some rather large leaps of fantasy in there, but what else can we do to occupy our time waiting...

The repetition of numbers to me is very similar to GRRM's repetition of phrases/epithets--which is very much in keeping with the epic poetry conceit- think The Iliad. Since these were "sung" stories, they needed catch phrases to give the singers a moment to catch up and a touchstone to keep the listeners on solid footing.

While I think the Night's King and the Last Hero could be the same, the rest just seems to try too hard,

I do think that Coldhands could be Night's King.

I also think the Sentinels will come into play at some point. They have a debt to pay if I recall.
