I thought this was a pretty strong start to this season. It's hard to believe there are only 5 episodes left, especially when you consider how much needs to be explained/wrapped up by the end of this.
So far, I think that Jon is approaching this the wrong way. He's trying to get everyone to see that politics don't matter and that the only thing worthy of discussion is uniting to defeat the Night King. However, what Sansa and Arya keep trying to tell him is that they do matter - it's impossible to throw tradition out the window, even when the stakes are as high as they are. Jon clearly doesn't want to be King of the North, let alone King of the Seven Kingdoms, but maybe he should. The North is never going to bend the knee to Dany (which will undoubtedly lead to some drama) given her family's history and the fact that she's an outsider, but they will be led by Jon. I believe the show is trying to commentate on a larger issue of humanity in that we tend to put more emphasis on and fight for the important things within our own personal lives and communities rather than global concerns. It's just easier to comprehend things on that scale. In an ideal world, everyone would set aside their differences and shift their attention to the impending large-scale doom, but that's just not how we operate. Jon needs to realize this and put duty before his own desire in order to unite the people of Westeros and save them. It's the only way - but I don't necessarily foresee that happening.
As for Dany, I don't ever see her relinquishing her claim to the throne - most likely foreshadowed when Sam says to Jon "you gave up your crown to save your people. Would she do the same?" Jon doesn't answer, which I think is telling. I hope he's starting to see the bigger picture here. The two of them must decide whether to remain allies or fight over the power of the throne. Jon will probably take the former and Dany the latter. Either way, I feel bad for Jon. Despite having to digest the news that he's actually the rightful heir to the Throne and that he's been sleeping with his aunt, he's got a severely difficult decision to make. No matter how hard he tries to stay away from responsibility, it always seems to find its way back to him.
Anyway, enough about Jon and Dany. Cersei has made it abundantly clear she has no intention of leaving King's Landing and doesn't care if everyone in Westeros dies, as long as she's the last one standing. I predict the North will lose the battle of Winterfell and retreat to King's Landing in hopes that Cersei will come to her senses and let them inside for the final stand against the Night King. However, she'd never do that. Unless they can sneak someone inside the walls to cross her off the map (or melt the Red Keep with dragon fire), they're going to die outside the gates as she smiles and drinks wine from atop her red castle. What an awful (yet great?) way to end this series!
That leads me to my next point...one of the scenes that stuck out to me most was the one with Sansa and Tyrion. I loved that Sansa called Tyrion out on his bulls**t in believing that Cersei would ever send her army to aid the forces in the North. I can't believe Tyrion, of all people, took her at her word. The writing of his character has really started to suffer and his motivations and actions are beginning to not make any sense at all.
Next week looks like it'll be far more exciting and I hope we get to see Dany's reaction to Jon's heritage and how the two of them move forward (or don't?).
