By the way, Tyrion being suddenly revealed as a Targaryen in the last episode would be ludicrous. Not going to happen.
Why is there a fucking spoiler in a prediction thread in the first place. If there is a place where people do not want to know the answer, this is it.
Bran keeps things moving rapidly along throughout but comes out all right at the end.
Arya asked someone a few seasons ago, what is west of Westeros? Apparently, no one knows. I think she will retire as an assassin and sail off into the sunset to become the Christopher Columbus of Planetos. And maybe tell Gendry she wouldn’t mind using Storms End as home base for her adventures. 
Arya killing Dany seems unlikely to me, since she already took out the Night King.
Arya killing Grey Worm, on the other hand …
I know I offered one prediction of Daeneris getting on Drogon and going back to Essos, but that can’t really happen. Everyone would know that she could simply fly her dragon across the narrow sea any time she wants and lay waste to anything she wants. So the minute she leaves, she and her dragon would have a huge price on their heads. Everyone in Westeros will want both of them dead if it can be managed. And as they established two episodes ago, killing a dragon is possible. Daeneris will be hunted for the rest of her life if she leaves.
Dany is unredeemable, but so is Drogon. Most Westerosi have an image of Drogon as basically a weapon of terror to be unleashed against the people at any time. He would be absolutely hated and feared.
So if Daeneris does not sit on the Iron Throne at the end, I would expect both her and Drogon to die in some way, or perhaps for her to die and Drogon to fly away never to be seen again until the next plot needs him.
Here’s one thing in favor of Daeneris ruling at the end: If she doesn’t, how do they resolve the problem of thousands of Dothraki and Unsullied still left behind? Without their queen, what do they do? I don’t think surrender is an option. Do they become a rampaging force? Does Drogon kill them, perhaps being warged by Bran? I don’t see them all calmly getting on a ship and going home. Rather, I think they’d avenge their queen. So we could actually see an ending where Daeneris and Drogon are killed, then Westeros gets to spend years essentially fighting guerrilla wars against thousands of trained soldiers loosed into a hostile country.
So, the ending looks bad for everyone no matter what. If Daeneris lives, she rules by fear. If she dies, her dragon and her soldiers could start laying waste to Westeros. If she and her dragon die, there is still a huge enemy army sitting in Westeros. I don’t see any happy endings for anyone.
Daenerys will die. Jon’s got a shot at death but will probably end up north of the Wall, or on it. He will not be King. Tyrion will probably die, likely executed by Daenerys before she is assassinated. Grey Worm is a dead man. Arya will live, and Sansa likely will too.
There may not be a new person on the Iron Throne. If there is, it’ll be Sansa or Bran or some figurehead, but there is a pretty good chance the Seven Kingdoms is done as a unified state. This is a chance for the various regions to make a break for it.
King’s Landing did not exist prior to Aegon’s Conquest - it was just where Aegon first arrived, hence the name - and so its status as a natural place for settlement isn’t clear. Cities of the past were often abandoned after disasters. Ani, Karakorum, Babylon, and more - some lasted a lot longer than King’s Landing. Given that anyone who survived the burning of the city is now at risk of death from starvation or dysentery, people would, if history is any guide, leave. They’ll take off as refugees for cleaner, safer places. If the Seven Kingdoms doesn’t survive as a unified state and King’s Landing has no political purpose for existing, sure, a city can die. That’s what happened to Xanadu and Persepolis.
Of course there are examples of cities destroyed and never rebuilt, but that’s not the norm. Look at WWII -how many cities were utterly devastated, then restored after the war? Dresden and Tokyo among others were firebombed and millions killed and whole regions of the city flattened. Berlin was close to being a pile of rubble by the end of the war - 80% of the city was destroyed. Stalingrad as well. Warsaw was almost completely destroyed. Hell, even Hiroshima and Nagasaki recovered, and even the areas bombed and irradiated are rebuilt.
In 1755 Lisbon was 85% destroyed by an earthquake, and rebuilt. The Mongols sacked Baghdad and almost completely destroyed it. It took centuries to recover, but it’s still around.
Cities are rebuild because they are generally located in strategically or economically advantageous places, but even if they aren’t, once a city is in place the economy around it changes, and then becomes dependent on that city. So there is great pressure to rebuild.
I would guess Sansa would end up as Queen.
I also predict the book fans will loudly complain and say they are waiting for the "real ending " from Martin which will likely never get written by him.
I think it is more likely than people realize that Martin has discussed the ending and what we are seeing on screen is the real ending, just executed very differently an with less insight into motivations than we’ll get from Martin.
I think in the books, it is(or was if he is changing it now) likely that:
- Arya kills the NK
- Dany destroys King’s Landing
- Cercei dies in the collapse
I think it is possible that they added or expanded:
- Clegane Bowl
- How the other dragon died in episode 4
- Euron stabbing Jamie
- Jamie hooking up with Brienne
I’m sure there was a note that said “Euron kills a dragon”, but book Euron is very very different than show Euron.
I have revised my thinking on this theory, because it dawned on me that “A Song of Ice and Fire” may be more revealing than it appears at first glance.
What if the central character of this story has been Arya all along?
Dany sends her adoring army out to catch and kill all remaining betrayers while she rides her dragon to get that one bitch over in Winterfell and burns that to the ground also. Her troops kill every last commoner running around the countryside looking for her former advisors. But even her troops betray her because, while collecting Tyrion and Jon’s heads, they lost Grey Worm in that fight. Just like Hitler, she blames her own people. Unlike Hitler, she has a dragon and burns all of them too. Adds another 100,000 or so swords to the Iron Throne and sits there until she dies too.
The Night King chuckles undeadily from beyond the grave.
Sansa sits on the Iron Throne.
Dany dies by Arya ex Machina, possibly with some face shifting foolery.
Tryion dies, probably by dragon fire.
Jon rides off into the frozen north.
Greyworm dies.
I’ll likely be away from a computer from Saturday until almost the end of May, so if I’m right, just hold all my fabulous prizes and such until I get back. If I’m wrong…well, it ain’t like it will be the first time.
Denarys tries to flame Jon.
Drogo says, “Mmmmmno, him Targaryan and me kind of like. Me no flame him.” Maybe he bites her in half, but something leads to her demise and Jon ends up the last Targ.
Pushed toward the throne, Jon says, “Naw, I don’t think so.” and plans to fuck off to the Real North with a snowboard, and a bag of Alpo for ghost. Tyrion convinces him not to do that because he’d be dooming the realm to chaos and more throne skullduggery. Jon has the dragon melt the throne. NOW the wheel is broken, and Dany sure enough facilitated that as she promised. Because power seeks Jon, Dany’s armies swear to him. Jon reclassifies them as cops and they are tasked with maintaining order. Jon begrudgingly accepts the title of high king, but rebrands the job as an arbitrator of disputes amongst the other kings. He does a lot of fishing in his spare time.
The long winters turn out to be an atmospheric effect of the NK’s migrations. The weather balances and the long nights are now summer-y nights.
At this point I’m not going to be happy unless Dany is walking along, talking to Grey Worm, when Arya gallops by on the pale horse and beheads her like the knight did to the lecturer in Monty Python & The Holy Grail. Now THAT would be awesome! 
Arya’s ending was the only thing I was right about for eight seasons! Well, minus the Gendry part unless that happened off screen.
Wrong thread.
