(Spoilers ahead for “Beyond the Wall,” the Aug. 20 episode of “Game of Thrones”)

The sixth episode of Season 7, “Beyond the Wall,” spends a lot of time with Sansa (Sophie Turner) and Arya Stark (Maisie Williams), who have less and less trust for each other. In the last episode, “Eastwatch,” Arya discovered a message Sansa wrote in Season 1 to her brother Robb (Richard Madden).
In the latest episode, Arya confronts Sansa with the message, saying that Sansa betrayed the family to the Lannisters by trying to get Robb to pledge fealty to Joffrey Baratheon (Jack Gleeson).
