7. 'The Winds of Winter' (Season 6, Episode 10)
… until the following season finale, that is. From its gorgeous opening sequence – a montage of King’s Landing luminaries preparing for the trial of Queens Margaery and Cersei, and we remember how that ended – to its rousing westward-we-sail finale, this was an episode for the ages. In between, Arya Stark took revenge against her mother's killer; her sister Sansa fed her rapist Ramsay to the dogs; and Jon Snow was crowned King in the North just as we learned he's actually a secret Targaryen (!) and potential heir to the Iron Throne.
