After a couple of hours of sweating over the clues, GRRM confirmed his clues. First, he confirmed that Elyas Gabel—who’s been in Waterloo Road, Casualty, Apparitions, and was a zombie in Dead Set—has been cast in the role of Jhogo, one of Daenerys Targaryen’s kas, her personal guard of Dothraki warriors (the three other guards will be played by extras or featured extras, at least in this season). Then, as we guessed, actor Joe Dempsie has been cast in the role of Gendry, a young, stubborn blacksmith.
Below are two videos featuring the actors:
