10 ways Game of Thrones could end

7. Bran is the Night King

There are so many Bran Stark theories floating around out there, you guys. He’s been important to the game so far, but what role will he play in the ending?

Well, let’s try this one on for size and see how it fits. One popular theory suggests that Bran — stay with me, now — is actually…the Night King.

Here’s how it all works: so we know Bran can travel through time, and that he can warg into people. This theory suggests that Bran, desperate to stop the White Walkers, will travel back to the time of Aerys “the Mad King” Targaryen, get inside his head, and plant the idea to manufacture wildfire and unite the armies of the living against the undead threat to the north. Only it fails and Aerys goes crazy, and the rest is history. Next. Then Bran wargs into the famed Bran the Builder from the Age of Heroes and actually builds the Wall. Only we know the Night King eventually knocks that down, so that plan doesn’t work either. Next. Finally, Bran will travel back in time and warg into the body of the human who eventually becomes the Night King, only now he’s gone back so many times he can’t leave, and he gets stuck in that body. Remember what the Three-Eyed Raven told him in season 6: “It is beautiful beneath the sea, but if you stay too long, you’ll drown.”

You can read more about the theory here. It’s probably too out there to be borne, but it would make for a pretty intense if Jon Snow had to kill his little brother, who it also turns out is his sworn enemy.
