Plot
Beyond the wall, Bran Stark has been training with the Three-Eyed Raven, learning to use his powers to view the past. As part of his training, Bran witnesses visions of Ned and Benjen Stark sparring as children, and Ned and Howland Reed fighting at the Tower of Joy.
Having been captured by the khalasar of Khal Moro, Daenerys Targaryen is brought to Vaes Dothrak, to live out her days with the Dosh Khaleen. Jorah Mormont and Daario Naharis learn of her captivity and travel to Vaes Dothrak. When the khals gather to determine Daenerys' fate, she sets fire to the Temple of the Dosh Khaleen, killing the khals but emerging unscathed.
Jaime Lannister returns to King's Landing with Myrcella Baratheon's body. Tensions escalate between Tommen Baratheon, Cersei Lannister, and the Faith Militant and the High Sparrow, as the High Sparrow refuses to let Tommen visit Margaery in prison or Cersei attend Myrcella's funeral.
After Doran Martell receives word of Myrcella's death, Ellaria Sand kills him and seizes control of Dorne, with the Sand Snakes also killing his heir Trystane.
The Sons of the Harpy burn the Meereenese fleet, stranding Tyrion Lannister, Varys, and the rest of Daenerys' court in Meereen. Varys discovers that the Sons are financed by the masters of Astapor and Yunkai, who have reclaimed the cities from the freedmen, as well as the slavers of Volantis. Despite the misgivings of Missandei, Grey Worm, and the freedmen of Meereen, Tyrion meets with representatives of the slave cities to offer them seven years to transition from slaving.
Arya lives in the streets of Braavos as a blind beggar. She resumes her training with the Faceless Men and her vision is restored after she claims to be "No One" repeatedly.
Sansa Stark and Theon Greyjoy are rescued by Brienne of Tarth. While Theon returns to the Iron Islands, Sansa, Brienne, and Podrick Payne journey on to the Wall to seek Jon Snow's protection.
In the Vale, Littlefinger arrives at Runestone, claiming that Sansa was kidnapped by the Boltons, and convinces Lord Robin Arryn to send the Vale forces to war.
In the Iron Islands, Euron Greyjoy returns from exile to kill his brother, King Balon Greyjoy. Theon returns and offers to Yara to support her claim at the Kingsmoot.
In Winterfell, Ramsay Bolton's status as heir to the North is threatened by Sansa's escape, and after Walda Bolton gives birth to a son, Ramsay moves to secure his position by killing Roose Bolton, Walda, and his half-brother. Several powerful Northern lords arrive at Winterfell to pledge their loyalty, including Harald Karstark and Smalljon Umber, who presents Ramsay with Osha, Rickon Stark, and the severed head of Rickon's direwolf Shaggydog. Ramsay kills Osha and imprisons Rickon.
At the Wall, Edd gathers the Wildlings to imprison the mutineers who killed Jon Snow. Davos persuades Melisandre to attempt a resurrection of Jon, which is ultimately successful. After executing the mutineers, Jon leaves the Night's Watch, as his death released him from his vows. After Sansa arrives at the Wall, Jon initially refuses to fight the Boltons. However, after Ramsay sends a letter to Castle Black threatening to kill Jon and the Wildlings if Sansa is not returned, Jon decides to gather Stark loyalists to fight.
