Game of Thrones season three just ended, so it’s time to talk season four! Entertainment Weekly reports one of the most revered characters from the books, Prince Oberyn Martell, will officially be joining the show. He’ll be played by Chilean actor Pedro Pascal, who most recently played Juan Badillo on Graceland. Also known as the Red Viper, Oberyn is a charming and dangerous prince of Dorne, whose sister was killed by the Lannisters via Gregor “the Mountain” Clegane when the Mad King was overthrown. The Red Viper comes to King’s Landing for vengeance. Since it’s Game of Thrones, who knows, he might kill or marry any character (or both).
