I don't think we're going to see Stark vs Stark. Spoiler reports say that Sansa is supporting Jon as King of the North. Littlefinger will probably try to pit her against Jon, and they're might be some arguments, but I don't think it will work. I know spoilers indicate that Littlefinger is alive at least up until the last episode this season. Bummer. I'm hoping that Sansa tells Jon why she didn't tell him about Littlefinger and Vale's support. We haven't gotten that quote from the trailer about "how it's all I think about, what they took from me."
This is far in the future but I think we will see a scene with Dany and Jon with Tyrion/Sansa being the link between the two. I know that Jon has met Tyrion before, but Tyrion and Sansa have got to meet each other again.
Wasn't there a spoiler about Oleanna being in Dorne awhile back, does anyone know why that would happen?
