I worry about that, too. There's a lot to resolve in a short amount of time. I have heard the final episode this season will be 1 hour 38 minutes, and that the average time for the next and final season's six episodes to exceed that. Is that accurate or merely internet rumor? I don't know. But there are still a lot of worthy candidates for the throne whose fates are left to be determined.
Since there are only three episodes left this season, events should be building towards the expected season-ending cliffhanger. What will it be? Daenerys and Cersei in a mud wrestling match would get my vote.
i think last episode this season is something like 81/82 mins long.
not sure about next season.
What is for sure is next season will focus on the main Battle vs Walkers. So the Throne storyline has to be resolved before that, ie this season or early next season.
My guess is the wall will come down in the 1st episode of next season. and the last episode of this season will have a group ( JS, Arya, Brienne and co) fight some of the walkers but then retreat.
To be honest, since the introduction of the WW I haven't been interested in the throne politics. But there's so much to go through, I think they'll rush the fight vs Cersei, it could be done by end of this season.
I don't see how Daenerys and Jon can focus on the WW AND at the same time focus on the throne, so I expect the latter to be resolved swiftly, unless I've got it completely wrong and it's somehow the other way round. But whatever Cersei's outcome, I doubt she'll still be around after the WW battle. Makes no sense, Let D and JS fight them and wait for them to come back and deal with Cersei, who just sat there waiting, I don't see it.
It would be ironic if the battle for the throne became a second thought to the characters but that's essentially Jon's speech to Daenerys. He says while we worry about all this petty throne ****, something way worse is coming. And he's basically openly saying, I don't give a **** about the throne.
Only the two ladies do and I think the way they're portraying Daenerys with her many titles, insisting Jon bends the knee, is a lead up to her eventually realising that actually maybe this throne **** is dumb, maybe Jon has the right frame of mind and I shouldn't obsess with it just because my ancestors did.
That's my thinking but as I said, would kind of negate the entire point of the series and ultimately contradict the title of the series.
