Stunning. In some ways it was obvious where some elements of the story would going, but they laid their cards down much quicker than I anticipated. Particularly in the final third of the episode. The first third having cleared up the main storyline so far in the series. The middle third takes the show in a new direction, and the final third blows the story wide open. This is thrilling stuff. And when I think of the places the story could be be going… I get giddy with anticipation. 10/10
