When asked what their favorite, craziest fan theory for the show was, the “” actors brought up a few popular ones, a few obscure ones and a few theories that might have even the most die hard fans scratching their heads.

’ favorite theory has to do with her on-screen little brother, Bran (Isaac Hempstead Wright). “In the trailers, there’s always a dragon flying over the Red Keep. Someone said, ‘I think that’s Bran warging into the dragon,’ and I was like ‘wooaahh!’”

Other theories include whether or not Stannis was really dead, that Roose Bolton was a secret vampire and that the White Walkers were actually going to turn out to be the good guys all along. Alfie Allen (Theon Greyjoy) wisely decided not to reveal his favorite theory, on the off chance that it turns out to be true and he gets in trouble for spoiling the end of the series. Smart man.

“Game of Thrones” fans are pretty unmatchable when it comes to sussing out spoilers and creating convoluted theories about the show. After all, they were the ones who possibly found (Kit Harington) alive in the Season 6 trailer just a few hours after it dropped.
