'Game of Thrones' Star Shuts Down Bran–Night King Theory

Why Didn't Bran Know About Rhaegar and Lyanna's Wedding?

Because Bran is the Three-Eyed Raven, he has the ability to go back in time and watch, and in some ways, influence events that transpired. One peculiar scene that he didn't delve into until the season 7 finale was the truth of his brother – or who he thought was his brother – Jon Snow's parentage and legitimacy.

It wasn't until Samwell Tarly recalled the ramblings of a Maester's private journal about performing an annulment and secret wedding for Prince Rhaegar Targaryen that Bran went back in time to watch his aunt, Lyanna Stark, marry the heir to the throne at the time.

"That was a bit confusing. The way I understand, it works like Bran has access. It's like he's got a Kindle library of every book of everything that's ever happened in the world," Wright said.

"He can access any of it in a heartbeat, but he hasn't yet sat there and read it all. The old Three-Eyed Raven had a thousand years to sit in that cave to read every single page of everything that's happened in the universe, and therefore be completely all knowing. Bran isn't completely omniscient. He can look up anything he wants, but he hasn't got it all by heart yet," he continued.

"At that moment [in the finale], Bran was like, 'Oh, yup, Rhaegar was [Jon's] dad,' but he doesn't think to explore it further. When Samwell Tarly says that [Rhaegar and Lyanna] were married, he can then confirm it. When his sisters come to him offscreen and go, 'Can you look up what is the real deal with Littlefinger?' He can go, 'He said this and this and this.'"

Wright on Bran's Goodbye with Meera Reed and Warging Into Hodor

One of the most heartbreaking scenes of season 7 was when Bran's loyal companion, Meera Reed, said goodbye to him once they reached Winterfell.

Wright discussed the idea that it was possible that warging into another human, Hodor, in season 6, could have possibly rendered him emotionless.

"Maybe the whole trauma of being back in time and being in someone else's body like that and messing with it so much, maybe that's what fried Bran's brain," he said.

"I hadn't thought of it like that. I think mostly what's going on with Bran is focusing on what needs to happen. Not in a callous way, but it doesn't matter that Hodor is dead or that Meera has left. They served their purpose. Bran needed to get to Winterfell so he could be with Samwell Tarly, so he could find this out and he can do whatever in the next season," he continued.

The English star says that Bran is looking at the bigger picture of the current events of Westeros as part of a "math equation."

"While Bran is still grateful for the help of Meera and Hodor, he just sees it as like a math equation on a page. He's like, 'We have to take away that from that so we could get to that, and we needed that to get to there,'" he said.

"He's looking at everything in a more calculated way now. He's like a very, very powerful computer or calculator. There is a sense of some kind of personality or some vague flicker of emotion, but more than anything, Bran is just looking at this spreadsheet of equations and things that need to happen. In many ways, I don't think Hodor and Meera are in his mind at all. He's so dead set on what has to happen to next."

How Bran Is Basically Doctor Manhattan from 'Watchmen'

In preparing for season 7, Wright explained that he and the GOT showrunners, David Benioff and D.B. Weiss, wanted Bran to be directly influenced by a specific comic book character.

"It was a really challenging thing to do this season. I had a meeting with David [Benioff] and Dan [Weiss], our showrunners, before we started filming. We had a chat about how we wanted to play Bran this season, and they suggested Doctor Manhattan from the Watchmen comic," Wright said.

"Bran was slightly based on that, existing in all these different times at once, knowing all these various things, being this emotionless rock connecting these different timelines and the history of the universe. We wanted that, but we didn't want a boring, monotonous character who would just go, "Yeah, I'm the Three-Eyed Raven, blah blah blah." It becomes a bit unbelievable, and also it becomes a bit dull. Not that the whole thing isn't completely unbelievable, but you know what I mean," he continued.

So that Bran still connects with audiences, Wright says that they still wanted him to be somewhat normal.

"We also wanted to make sure that there was a bit of Bran left, a glimmer of a person still in there," he said. "It's like he's the first cyborg. We just connected a supercomputer to a human being's brain. He's a mainframe, but there's a little bit of his personality. More often than not, though, Bran is a vessel for human knowledge."
