Haters gonna hate. I do not understand it either Jaime who is one of my favorite characters gets more love than Tyrion, which I do not understand. I feel that Jaime should get more hate from pushing Bran out the window and killing Jory, where Tyrion gets more hate from what he did to Shae who betrayed his trust by speaking against him at Tyrion's trial.
2. Randyll Tarly
3. The Faith
4. Possibly Littlefinger will want the Vale to side with Aegon, but Sansa won't she will want to return North to help Rickon.
5. I can see the RiverLands lords joining just to piss off the Lannisters.
Depends the dragons could be without their mother with the upcoming battle for the dawn 2.0. I think it would be interesting plot wise if Dany dies before the battle of the dawn and the dragons will then be uncontrolled. So then when things look like they are going bad Jon has an arthurian moment and gets back control over the dragons being the last Targaryen heir and he and his sisters Sansa and Arya are all dragon riders.
