Jon Snow is angry. Cersei is angry. Danaerys is furious, despite the fact that she’s getting regal as hell about it. In fact, it appears like most of the characters on “Oathbreaker” are angry, because they’re fed up with the rules they’re forced to live inside. Add to that an additional immensely satisfying peek into Game of Thrones’ previous, courtesy of Bran, and you have another fantastic episode in a season that promises to be full of them.
