With Daenerys, it's a bit interesting, because this episode is really shaving down the possibilities:
1. She's been through the emotional wringer - she's lost two of her dragons, her best friend and advisor and her protector and bodyguard. This is further reinforced with the scene in the dining hall which highlighted her isolation from the Northerners and by proxy Westeros.
2. She's found out that her entire reason for being, the destiny complex that has essentially kept her going through innumerable challenges across the sea, the death of her family, of her brother, her husband, to unite the Seven Kingdoms, is technically not her legal right.
So the episode has gone out of its way to essentially paint her as a complementary figure to Cersei, as a tyrant, who is willing to do anything for the throne. To force her love to keep a secret from his family.
Either:
(a) With rather clumsy foreshadowing, she's determined to burn the city to the ground in revenge and destroy Cersei, possibly requiring some former friend or lover to put her down to save thousands of people.
OR
(b) That despite everything, despite what she's been put through by Cersei and others, she still manages to stay true to her original purpose of not being a tyrant. That she sacrifices herself to save the people or some such.
In either case, however, I don't see her on the Iron Throne.
Unfortunately, this development has not been slow, but rather rapid, over the course of one or (maybe?) two episodes. Again, I think the victim of expediency due to time constraints but you do have to acknowledge that the past few weeks have been pretty overwhelming for anyone.
