G.R.R.M is relevant everything - especially the Night King is not a random person. Stark keeps a secret, just like these other Houses (Euron Greyjoy and Blackfish).

I believe Bran has evolved to move outside their world and tapped the weirwood trees. Just like the Night King had evolved in thousand years to learn magic.

Also, Childern improved thier magic to get Benjen in support.
