Season 6, Episode 10 (June 26, 2016)
Director: Miguel Sapochnik
Writers: David Benioff and D. B. Weiss
Recap: In the North, Arya serves Walder Frey a pieful of his own children before murdering him, avenging Robb and her mother's deaths. Cersei ignites a cache of wildfire barrels underneath the Sept of Baelor to blow up the High Sparrow, Margaery, Loras, Lancel, and all the other Faith Militant, and close out the show's most tiresome plotline in one fell swoop. When King Tommen learns that Margaery, whom he really, really actually liked, is dead, he throws himself from the roof of the Red Keep. Jaime and Bronn arrive back at King's Landing just in time to see Cersei crowned Queen of the Seven Kingdoms. Meanwhile, Sam and Gilly arrive in Oldtown and Sam gets to visit the Citadel's massive library. Nerd. In a vision, Bran visits the Tower of Joy and learns that the Jon Snow parentage theory of R + L = J is true, as he watches a dying Lyanna Stark hand over a newborn to her brother Ned. Ellaria and the Sand Snakes take Varys' advice and agree to ally themselves with Daenerys. And in Meereen, Daenerys leaves a reluctant Daario behind to rule in Essos in her stead, taking her army of Ironborn, Dothraki, and Highgarden soldiers to sea in her brand new armada, sailing, at last, to Westeros.
Most shocking moment: If you hadn't plunged deep into the long-existing theory well concerning Jon Snow's origins, you were probably extremely shocked at the twist that Jon isn't Ned's son after all, but instead the offspring of Lyanna Stark and Rhaegar Targaryen -- and, effectively, the rightful heir to Westeros.
Why it's important: This is the episode that sets up the endgame of Daenerys' arrival to conquer Westeros, but it also wraps up some dangling threads and finally confirms that R + L does, in fact, = J. -- ES
