Remember this scene from the first episode of Game of Thrones this season? Our introductory scene to Stannis-Davos-Melisandre at Dragonstone. It’s interesting, in the show, we’re led to believe that Davos is pretty much an atheist (or maybe agnostic), he doesn’t believe in any god, old or new. But we don’t really know how devoted Stannis was to the Seven Gods before Melisandre convinced him to convert to the religion of the Lord of Light. Not that he seems all that convinced about the Lord of Light in this episode, he sounds entirely NOT convinced when he was saying the words “for the night is dark and full of terrors”.
Apparently they used THIRTY swords to shoot that scene where Stannis pulled out the flaming sword!
