So, Agatha's related to a pope. A Heterodyne pope. Even if he went full Heterodyne in the end, I'm really not sure what to think about that.

Also, not sure about Der Kestle and the Train's conclusion. I mean, Agatha wants to be a decent person and she definitely doesn't want to be like Lucy. But, she's recognized that she has responsibilities to her town, her people, and the various monsters who served her family. She's a grayer character than she was in the beginning.

She's not planning to play a long game, but I'm not entirely sure where she's going to wind up (although I guarantee she's going to do better than Daenerys, no matter how crazy she gets).
