Um, Can We Talk About These Insane Game of Thrones Theories For a Minute?

If Bronn is able to warn Winterfell before they get in too deep in battle, it could save them from being surprised by the Night King and give them enough time to figure out what to do instead. Bran seems positive that the Night King is going to be coming after him, so we're hoping that if the battle goes down this way, he'll have a plan for Winterfell's next move. Does this mean that Bronn is really their only hope? We are sort of banking on that answer being yes.
