Others' mileage may vary, but I think this somewhat confirms my analysis of what the rest of this season/series looks like in terms of narrative structure:

Yes. And I honestly don't think that was ever really in doubt. Especially as far as the TV series is concerned, the article you linked has hit on what appears to be the moral of the story. Undead armies, magical frost demons, and dragons are one thing. Terror that can't be fully quantified or overcome. But they pale in comparison to what somebody like Cersei Lannister can, or will do. Somebody human, who we should be able to understand. But who will nevertheless destroy everything and everybody she touches just because she can.
