I have been waiting YEARS for Bran to warg into a dragon. I thought that was going to be the whole point of his arc since they’ve been telegraphing it forever.
I still think it will happen. Dany or Jon die. Bran wargs into their dragon and torches Kings Landing.
IDK, I feel like it's not the 3 Eyed Raven's place to interfere in the battles of men. I understand how he had to be involved in the fight vs the NK. Now he should really be nothing more than an observer of history. Why he said he can't be the Lord of Winterfell.
