23. 'High Sparrow' (Season 5, Episode 3)
From sins of the flesh to wrath of the gods, this Season Five highlight runs the gamut of human experience. In King's Landing, recent regent Tommen and his older, wiser bride Queen Margaery (repeatedly) consummate their marriage of convenience. Meanwhile, the grandfatherly fanatic for whom the episode is named, brilliantly portrayed by Jonathan Pryce, begins his rise to power. At the Wall, Jon Snow executes Lord Janos Slynt, the man who betrayed Ned Stark and who admits "I've always been afraid!" as the sword falls. Elsewhere, the exiled Jorah Mormont kidnaps a Tyrion Lannister haunted by the murder of his ex-girlfriend, while Arya Stark is initiated into the mystic mysteries of the Faceless Men assassins. Whatever you like about Game of Thrones – sex, violence, drama, political skullduggery, beheadings – you'll assuredly find it here.
