'Game of Thrones' Season 4: Isaac Hempstead Wright on Bran's powers and journey

game-of-thrones-season-4-bran-weirwood-hbo.jpgBran Stark is arguably the most magical character on "Game of Thrones." He can warg into the minds of animals (and humans, as was discovered at the end of Season 3), and also has the greensight, which can allow him to see the future and past.

But, as they say, with great power comes great responsibility. Bran is on a journey of discovery in Season 4, and though he won't have as much screen time as some of the other characters, his trajectory is very important.

"He firmly knows where he's going now," Isaac Hempstead-Wright tells Zap2it. "As he said in Season 3, he has to go beyond the Wall. It's not a choice. It has to happen because there's this strange, mystical force that is pulling him like a rope, and he's got no idea where he's going. All he knows is he has to go because all the signs point to the fact that it is something powerful or meaningful. ... Season 4 is more of Bran definitely on a firm trajectory to wherever he's going."

As fans of George R.R. Martin's "A Song of Ice and Fire" novels know, Bran's storyline is advancing faster than some of the other characters' when compared to the books, and the show could potentially get into his "A Dance With Dragons" storyline.  

"I think what's happening is some storylines are being accelerated, and I think Bran's maybe might be. But again you don't really know until the next season and maybe the season after that comes out," Hempstead-Wright says. "Other storylines are still at book three or whatever. It will be interesting to see how all that pans out considering different events will be happening at different times. Some of the hardcore fans might get a bit upset."

Hempstead-Wright calls Bran warging into Hodor in Season 3 an "enormous moment" for his character. It led Bran to question whether he should have taken over another person's body, and whether what he did was bad. Hempstead-Wright teases that Season 4 will involve Bran exploring his power of greensight.

"We don't know if Bran knows exactly what's going to happen and exactly what the result is going to be. He hasn't quite developed that yet or is just sort of running blindfolded into a combine harvester," he says.

What Season 4 will show is Bran turning more and more to his powers. "He's lost so much. I think him over other characters more is he has lost probably the most," Hempstead-Wright says. That's part of why he likes his ability to warg.

"If you could actually suddenly go back into the wolf, and you could run and jump and do everything you always wanted to do knowing that you'd never be able to do it again as you, I don't get why he wouldn't want to permanently warg into [Summer]," he says. "But I don't think that means he'll never sort of walk again in a broader sense. I think definitely he will have some significant impacts through other media rather than just his body through the wolves. I think there will be some serious stuff."

"Game of Thrones" Season 4 premieres April 6 at 9 p.m. ET/PT on HBO.
