“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 Jon Snow (Kit Harington) alive in the Season 6 trailer just a few hours after it dropped.

But what does the cast think of some of these crazy fan theories? They love them.

When asked what their favorite, craziest fan theory for the show was, the “Game of Thrones” 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.

Maisie Williams’ 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!'”

“The weirdest theory I’ve ever heard,” says Ian Beattie (Ser Meryn Trant), “Was that Cersei Lannister (Lena Headey) was Jon Snow’s mother.”

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.

Surprisingly enough, no one mentioned the most popular fan theory: that Jon Snow is in fact the son of Lyanna Stark and the former prince of Westeros, Rhaegar Targaryen. This hidden lineage would put him in line for the Iron Throne right along with Daenerys.

Does this mean that they were all simply smart enough not to spoil something that’s likely to be incorporated into the show? Or is it too far out there even for them?

Maybe Alfie Allen will tell us if this was the theory he didn’t want to spoil when the show is all over and done with.

“Game of Thrones” returns Sunday, April 24th to HBO.
