During a snowstorm, Stannis' camp is sabotaged when Ramsay's party destroys the camp's siege equipment and food stores, while inflicting heavy losses on the army's horses. Sending Davos to the Wall to request supplies, Stannis reluctantly allows Melisandre to sacrifice Shireen, burning her alive at the stake, despite her pleas and Selyse's objections. Snow and the others return to the Wall, allowing the wildlings to pass South. In Dorne, Doran permits Jaime and Bronn to return to King's Landing with Myrcella, provided Trystane accompany them and serve on the small council in Oberyn's stead. The former also pardons Sand and her daughters. In Braavos, Arya spots Trant accompanying Mace Tyrell, Margaery's father and the Master of Coin. In Meereen, the fights at Daznak's pit begin, and Daenerys is stunned to see Mormont amongst the combatants. His triumph is interrupted by a fierce attack by the Sons of the Harpy, who quickly surround Daenerys and her supporters, including Mormont. Just as all hope seems lost, Drogon arrives, and Daenerys mounts him and flies away from the pit, her followers watching in awe.
