Jon's mission continues north of the Wall, though the odds against his ragged band of misfits prove greater than he imagined. After the group captures a wight, the White Walker army besets them, but not before Jon sends Gendry back to Eastwatch to dispatch a raven to Daenerys requesting help. During the night, an injured Thoros freezes to death. As the wights are about to overwhelm the group, Daenerys arrives with her dragons, destroying many of them, but the Night King kills Viserion with an ice spear. Daenerys flies off with the men, unable to rescue Jon, who is saved when Benjen Stark intervenes and sacrifices himself.
Reunited with Daenerys, Jon pledges himself and the North to her as queen. At Winterfell, Littlefinger schemes to isolate Sansa: tensions between Arya and Sansa grow after Arya discovers the letter Sansa was forced to write begging for Robb's fealty to Joffrey, and Sansa in turn finds Arya's collection of faces from Braavos. At Dragonstone, Tyrion counsels Daenerys about the upcoming negotiations with Cersei. The Night King reanimates Viserion, making the dragon part of his army.
