The clocks have been turned back and the Long Night is here once again. For Game of Thrones fans, these are the toughest days, when filming has begun, but no spoilers have leaked. It's the time of year where we keep warm around the fires of Reddit, making up insane theories of how the show will finds its end and what will happen to the characters beyond that. Apparently, some GoT actors are joining in the fun. Isaac Hempstead Wright, who plays Bran in Game of Thrones Season 8, has an excellent theory on what happens to his character. It's exactly the sort of wibbly-wobbly, timey-wimey sort of thing one might expect from the Three-Eyed Raven.
As fans will remember, the way Bran became the Three-Eyed Raven was via a time loop known as the Ontological Paradox, which is the sort of thing that happens inside a "stable time loop." (Those who are stuck in a stable time loop are actively responsible for the events that underpin their own present.) That is to say: Bran going back in time while he was also warging into Hodor, commanding him to save his (Bran's) life in the present, caused Wyllis to become Hodor in the first place, so that he could one day save Bran's life when he commanded it. Savvy?
Well, if a paradox caused Bran to become the Three-Eyed Raven, why couldn't another paradox cause Bran to set out on the journey in the first place?
Here's Hempstead Wright's idea:
I like the idea that it’s actually a full circle and Bran becomes the Three-Eyed Raven that was in his dreams when he was younger. I like the idea that it’s a deterministic, destiny driven thing where the old wise man went back in time as the Three-Eyed Raven to tell the young Bran to go north to the cave and it’s a paradox.
To explain, what Bran is suggesting here is that he, once he becomes the Three-Eyed Raven, went back in time via his raven body guise, and that it was himself that Bran saw in those dreams back in the first couple of seasons of the show, and not the Three-Eyed Raven he met in the tree.
This would happen at the end of the events of Game of Thrones Season 8. This would be after Bran probably screwed Daenerys and Jon's relationship up by telling them that Jon Snow is actually Aegon Targaryen, Daenerys' nephew and the ranking heir to the Iron Throne instead of her. (Bran is, as we know, very good at screwing things up by being self-righteous and not thinking how people, or Night Kings, will react to things.)
Further, this also probably happens after everything is set right again, and Daenerys, Jon, and Bran band together to beat the Night King, with Jon and Daenerys doing so in the real world, and Bran via the vision world. (The dragon having three heads and all.)
One would hope that perhaps in his Three-Eyed Raven guise, Bran might try and talk a little sense into himself. Perhaps, he might gently suggest considering the consequences of his actions, like going to spy on the Night King, or telling Jon that the woman he's sleeping with is in fact an incestuous relative.
But perhaps Bran, as the Three-Eyed Raven, figures what's done is done. The past is already written. The ink is already dry. Yes, it will suck for Bran to keep doing these things over and over in an endless stable time loop, but if that's what it takes in order to keep the Night King from victory, so be it.
Game of Thrones Season 8 will arrive sometime in the distant future, say, 2019 or so, on HBO.
