Catching up:
Darth Cersei looks awesome. Not sexy, just awesome.
I think people are reading too much machination into Sansa. I think from her point of view, she is back home, her brother is King of the North, and she can now go about rebuilding Winterfell and helping to plan for the long winter. She has no ambitions to greater power that I can see - but she’s also not going to allow herself to be used and abused again. The look she shared with Littlefinger was more about her realisation that so long as he was around, it just isn’t going to be that easy. She knows his ambition, that he wants her, and that he’s capable of doing almost anything to get what he wants. I thought the look they shared was pretty chilling.
Arya has no idea that Jaime pushed Bran out the window, does she? If she did, he’d probably already be Frey-Food. It will be interesting to see who she goes after next. As for the face she used - I think I’ve learned from this season not to over-think things. She had a face. We don’t know where she got it. She probably has more. That doesn’t mean she murders people for them - maybe she just seeks out fresh corpses, of which Westeros has plenty.
Daeneris’s fleet: People are speculating as to where it’s going to land. Didn’t we already establish that it was going to stop over at the Iron Islands and help Yara overthrow Euron? I didn’t think the Iron Islanders were all going to help Daeneris take Westeros - more like she helps them take the Iron Islands first, and then she doesn’t have to worry about her flank as the rest of the fleet goes on to the mainland. Or maybe the fleet will split apart, as I wouldn’t think the Tyrells and the Dornish would be that interested in spilling blood and treasure for the Greyjoys.
As a guess, I’d say that the Greyjoys take back the Iron Islands, and then their armies will join with Jon and the other men of the North in fighting the walkers. Theon will argue for this after Sansa asks for his help. He still has a debt to pay to House Stark and the north in general. Heck, maybe he’ll wind up back at Winterfell eventually.
As for Littlefinger - he can fully believe in the White Walkers, but that won’t stop him from simply seeing them as another tool to be used to further his ambitions. But it’s hard to see how he can possibly carry out his plans now that winter has come. He needs to be thinking about getting his army back to the Vale and provisioned, or they are all going to die in the snow. Winter in Westeros can last years - even decades. You would think that people in the North especially would be focused on stockpiling food and wood and everything else they can get their hands on. All of which makes it really hard to provision armies and take them across a continent.
It will be interesting to see if any of these people end up married or paired up at the end. The obvious one is Jon Snow/Daeneris, which makes me think that might not happen. And what about Sansa? Her possible mates seem to be Littlefinger, Jon Snow, Tyrion Lannister… I’d love to see Tyrion and Daeneris ally with Jon and Sansa, and to have Tyrion wind up with Sansa. It makes sense - she has now seen enough true monsters in the world that she might find Tyrion’s dwarfism utterly irrelevant compared to his character.
We also have three sympathetic eunuchs (band name!) in the final mix - Grey Worm, Varys, and Theon. It will be interesting to see what happens to them. They are still hinting at a romance between Grey Worm and Missandei, and I’m not sure how that’s supposed to work out.
As for the Lannisters, it seems like there is not much left for them other than a tragic ending. They have no money, no allies, and a public that must despise them after Cersei’s stunt at the sept killed their religious leader and their more-beloved Queen. The only way she can rule now is through fear, and that requires a fiercely loyal army. Does she even have one? One she can actually pay?
Speaking of religious leaders - there have been a few posts questioning which Gods actually exist. I was always under the impression that the Old Gods are real, and that the Lord of Light is real, but that the ‘seven’ were just a political invention to keep the people in line. I don’t think we’ve ever seen any of the ‘seven’ do anything. But if they were real, they certainly didn’t do anything at all to stop the destruction of their holiest site and most of the leaders of the faith. So I think the evidence is even stronger that the official religion is the only one that’s not true.
