There are some Game of Thrones mysteries in Westeros that will never be solved, no matter how far the show outpaces the books. Why is Ramsay Snow so evil? Did Tywin Lannister know about Rhaegar's annulment? But there are some mysteries that date back to season one which never should have been mysteries, it's just that fans didn't know what was a clue and what wasn't. The biggest of these is what Ned Stark whispered on Game of Thrones just before he died. Some have thought it would be a confession of Jon Snow's parentage. (After all, it's not like Illyn Payne, the executioner, could tell anyone, he has no tongue.) Others thought it might be whispering his sister's name, or "I kept my promise," in that he never revealed the truth of Jon's father. Maybe he was whispering Sansa or Arya's names, in hope that Payne might help them escape. Theories have abounded throughout the series, in hopes that perhaps one day we would find out, maybe through Bran Stark's Three-Eyed Crow abilities. (Personally, I was hoping for it to be "Hail Hydra.") But so far, Bran hasn't heard what his father whispered, despite having seen Ned beheaded in multiple visions. That's because, according to Sean Bean, who played Ned Stark, what Ned whispered wasn't actually of any importance. OwlWhite87 on YouTube Talking to HuffPost , Sean Bean revealed that all he was whispering was a little prayer, not unlike most people who are executed in broad daylight. He agrees "it appears" to be something important, but in fact, not so much. I couldn’t be too specific, because I don’t know if religion [like that] was around in those days, whatever they were. I just thought, ‘What would you do if this were really gonna happen?’ You probably would pray. You probably would murmur some words and you’d keep it quiet. You’d keep it to yourself. In fact, Ned Stark is a fairly religious man in the books. He believes in the Old Gods, the kind of deities that stretch back to the time of the Children. That's back when greenseers who used trees to see through time and space were not confined to far beyond the Wall. Those gifted like Bran were simply part of the culture. So Bean's choice to have Ned pray during his final moments would actually be something Bran would hear. Or, more correctly, the Three-Eyed Raven before him would have heard. It would be a prayer for mercy and grace. CrisTh3Crisp on YouTube That's what Bean was going for: It’s quite subtle in that many people wouldn’t pick it up. It was an interesting thing to do for me at that point. There’s not much you can do really, you’ve got your head on a block. That’s about the only thing you can do is murmur. Except it did not occur to Bean (or to a lot of the actors involved in Season 1 of Game of Thrones ) how completely insane the fans are. Even the most subtle prayer for a quick death can spawn thousands of fan theories before the truth can even get a pair of shoes on. As for Ned Stark maybe having some sort of cameo in the final season, Bean gets these questions every year and fields them graceful. When asked if the showrunners ever said there was a chance to come back he demurs: "No, they’ve never said that." And yeah, I’ve heard rumors, but not from very good sources that I might be back. But I think I’ve done my time there, and I created a good character. It’d be rather strange to see him resurrected. With only six episodes to wrap up the story, it's not like there's a lot of room anyway. Game of Thrones ' final season will mosey over to HBO whenever it feels like doing so in 2019.
