It's safe to say viewers aren't exactly loving the new Bran on Game of Thrones.
The youngest surviving Stark sibling (RIP Rickon) finally made it back to Winterfell for that long-awaited family reunion this season, only to proclaim he is no longer Bran, but instead the much more annoying Three-Eyed Raven.
Since then, he has mortally offended Meera and confused the hell out of Sansa, as well as Arya Stark.
However, if this fan theory turns out to be correct, it could see Bran become the real Stark sibling of many faces. Soz, Arya.
The theory would see three-eyed raven Bran travel backwards in time and warg his way into the man who later becomes the Night King, with the goal of stopping the Children of the Forest from creating the White Walkers in the first place.
However, this ultimately backfires when they don't believe him and pierce the first man's heart with Dragonglass while Bran is still trapped in his body (turm0il26 argues Bran does try to jump ship here and travel back to the future, but too bad. Because he stayed too long in the past, he's stuck there—which Brynden and Jojen did warn him about previously), thus creating Bran, the Night King.
The theory becomes arguably more plausible when you pair it with the White Walkers' creation scene from season six episode "The Door"
While watching the events unfold, Bran is unusually tense right from the off, even though at this point, he can only see things at a distance.
Tie that in with the fact Bran's position against the rock directly mirrors that of the Night King's against the tree, the frame-to-frame transition of the Night King's eyes to Bran's when he returns to the present is immediate and that the Night King can touch Bran when he wargs, and it's a pretty compelling argument.
Oh, and then there's this confession from Leaf that has us almost convinced.
BS: "It was you? You made the White Walkers?"
L: "We were at war. We were being slaughtered. Our sacred trees cut down. We needed to defend ourselves."
BS: "From whom?"
L: "From you."
See, Leaf literally TOLD Bran she was defending herself from him.
Of course, this conflicts with other theories out there that suggest Bran himself is the legendary Brandon Stark who built the wall and after whom he is also named (according to Old Nan's stories, anyway).
Nonetheless, we're shook all the same.
