Was poking fun at all the links for leaks put out that never amount to anything.
My theories are NK has always pursued 3 eyed raven cause it's been a chess game between the 2. NK more powerful of the 2 but for thousands of years both the 3 eyed Raven and man were well protected by spells and the ability to see through the weirwood net. Bran fucked it all up while in training and then accessing the weirwood net while the 3 eyed Raven was asleep. Once NK touched him, it opened up all that protected man before so it truly is all Bran's fault. NK also wants to take out 3 eyed Raven before his vulnerability is exposed. This may be where Tyrion's talk with Bran comes into play.
Jon destroys NK in round 2 w/sacrifice of Mel beforehand. As much as Dany has wanted the throne all along, she will not have the desire for it in the end and, instead, she and Jon denounce it and make it so it's no longer a thing, giving each of the Kingdoms the right to rule themselves.
