Game of Thrones 7 gave us a lot of huge reveals regarding characters, but there's certainly still some mystery left when it comes to the last season which airs 2019. There's been a fan theory going around that Max Von Sydow's Three-Eyed Raven character was actually an older Bran Stark, and Isaac Hempstead-Wright prefers this theory over the "Night King" one.
Talking to Nerdist, Hempstead-Wright said:
"It seems a little bit more plausible [than the Night King theory] and it doesn't have so many insane ramifications for the story line. That would be quite a neat little thing that would sum up that whole circular arc."
As for Bran being the Night King, he says that he feels that twist wouldn't feel natural for the series. He continues:
"It just doesn't feel like Game of Thrones. It feels a little bit too Hollywood."
Sure there's still a lot of questions to ask regarding Sydow's Three-Eyed Raven's origin, and it would be neat if everything would come full circle, and Bran would end up in that tree. Then again, I'm also completely happy just to have Bran pave his own future. There are also several theories that Bran is the same Bran the Builder who built the Wall of the North.
Hopefully nobody has guessed what will happen in the last season. Some fans had already speculated years ago that Jon Snow was actually the son of Lyanna Stark, and it bummed me out for the reveal. I'm just happy we still got a surprise when we realized his real name was Aegon Targaryen.
Game of Thrones 8 comes out in 2019.
