[NOTE: While we do not normally include HBO's videos for the Game of Thrones series, we make an exception here because Martin makes two statements that are relevant to the novels: one, that Theon Greyjoy (and his brothers) were "properly" drowned when children, as opposed to the sort of baptismal bath that infants now often receive; and two, an explicit connection of Stannis Baratheon to the prophecy of "the prince who was promised", clearly indicating that this prophecy and the prophecy of Azor Ahai reborn deal with the same prophesized savior.]
[Note: This event was a separate talk at TIFF, that took place to his public "In Conversation" event. Video of that event can be found here.]
