Ok so...is Bran the Night King?
theory gaining a crap ton of steam since the final last week...it has been a theory for some time now.....however when the army of the dead is shown overhead as they breach the wall the army forms the sigil of the direworlf...
In the books the Night King is a fallen Lord Commander of the Night's Watch who was rumored to be a Stark..and the Night King was created by the Children of the Forest when they captured their first ever man.....of Which Bran was captured by the Children of the Forest...and with his time traveling ability he has said it is possible to be stuck in the past in someones body if you stay too long and in his visions has come face to face with the Night King
Remember that Bran is living actively in multiple time lines...is it possible that Bran was the King of Winter Stark from lore, who ruled long ago, but in current time became the first man captured by the Children of the Forest thus transforming his past self into the Night King to serve the children of the Forest as guard against the first man , but it didn't all become a reality until the Children captured Bran in the time line we are in now??
