@Phantele_ Alright I'm on board with that. They just ran out of episodes to make it work. She 'went mad' in a week long off screen gap in world. They could've smoothed this over with 1 additional episode and a conversation with Tyrion about her past actions though honestly.
@Phantele_ I think the idea is that the combined burdens of grief, and insecurity about the source of her power have pushed her to breaking her code. Her power is the dragon, she has to use it to garner fear. There are no antagonists left, the story is Jon v Dany. Good Dany is gone gone.
