Ever since the memorable Hold the Door episode (literally "The Door"), which brought out Brans's ability to influence past, present, and future, has come to the fore – Game of Thrones fans have come out on top Life speculates The role of Stark Boy in other events in this series. One of these theories is that Bran is actually the real Brandon Stark who built the Wall – a theory that is often based on this passage from George R.R. Martin's books refer:
"I could tell you the story about Brandon the Builder," said Old Nan. "That has always been your favorite." Thousands and thousands of years ago, Brandon had raised the builder Winterfell, and some said the wall. Bran knew the story, but it had never been his favorite. Maybe one of the other Brandons liked this story. Sometimes Nan talked to him like she was Brandon, the baby she nursed all those years ago, and sometimes confused him with his uncle Brandon, who was killed by the mad king before Bran was born. She had lived so long, mother had once told him that all Brandon Starks had become a person in her head.
Another similar theory is that Bran is actually the NightKking, which makes sense because his blood is the first men the forest children used to make white wanderers out of men. It's a theory that actor Isaac Hempstead Wright told me that he thinks it would be pretty cool to be the Night King ̵
We have just seen the scene where Jamie and Robert Baratheon were discussing the Mad King and the events surrounding Jamie killing him. Jamie says he kept saying, "burn them all," even after he stabbed him.
My friend raised a good question that I never considered – is it possible that he had some sort of vision for the future and saw The White Wanderers come and that drove him crazy? and as a result, he said in relation to the White Wanderers "burn them all"?
Now that we're going a step further, we know that the story goes that the crazy King Aerys Targaryen was known to hear voices. Is it possible that Bran traveled back in time and dealt with Aerys Targaryen's mind as well as sweet, sweet Hodor? Consider here the motivations of Bran. The Targaryen dynasty was the last time there was a single Westeros. It is possible that he used his Three-Eyed Raven abilities to convince Aerys to fight the White Walker threat with the full power of the Seven Kingdoms. Another reading might be that Bran knows he has to manipulate Aerys to start this whole series of events.
This would mean that Bran is behind the biggest event in recent Westeros history and is responsible for ending 300 years of Targaryen rule. It's a lot of pressure for an angsty teen.
