I liked Jon petting the dragon. I hope he learns about his heritage and rides a dragon before the season ends.Fast moving pace again ... I like it. Previews are going to make it hard waiting another week to see who makes back into the wall safely and with a walker . Littlefinger is playing with danger against Arya. I really was surprised with the confrontation between Sensa and Arya. Not the loving sister bonds they once had.
I was surprised that Jon didn't stop at winterfell on his way to the wall. That seemed out of character for him. Unless perhaps East Watch was closer and that is where he went.
What did the note say that Arya stole?
