Trivia

While filming this episode, the producers had Tom Wlaschiha (Jaqen H'ghar) and Faye Marsay (The Waif) come to set in full costume, for the benefit of the paparazzi. It was revealed in Game of Thrones: The Last Watch (2019) that they were brought back because the producers wanted to stoke the popular fan theory that the Waif killed Arya in their off-screen fight in Game of Thrones: No One (2016) and had been masquerading as Arya by wearing her face since then.
