An add for upcoming moments on HBO ran last night during Westworld and Game of Thrones fans went crazy. Screen grabs popped up on-line and folks tried to scramble to see what they meant. The images are of Jon Snow, Sansa Stark and Arya Stark.
It appears that Sansa is standing in front of the weirwood tree in Godswood, leading fans to speculate she is meeting Littlefinger in secret. Also, they believe Jon is talking to Sansa in that image. Why Arya is on a horse is anyone's guess.
Game of Thrones season 7 kicks off in 2017.
