Crazy (??) theory I've read recently.

Bran was told that when he wargs, he mustn't stay to long or he'll get trapped.
We also know that he can influence the past; was responsible for Hodor.
Biggest twist of all big twists is that he goes back to the creation of the Night King again and tries to stop it, but gets trapped...
Bran IS the Night King!!


Can't see it myself, but posted for discussion ( or ignore it )
