Here’s my off the wall prediction for the ending:
While I LOVED the episode last night, something felt a little unsatisfying about it this AM that we literally have been worried about the White Walkers since season 1 and finally the living battle them and they die without us even knowing what their purpose was. Were they just pure evil? I don't think so...I think that's what the writers want us to think, but GRRM is very political and supposedly the Walkers are supposed to be a metaphor for climate change. Let's remember, this isn't some devil that was created at the beginning of time...the children of the forest literally created the Night King to help them against the humans. GoT is a series which literally ties so many loose ends up - certainly the important ones - and I just can't accept that the White Walkers are done and gone without us ever knowing why they were marching south for the first time in 1000 years.
I think over the next couple of episodes some weird stuff is going to start happening - and it will be clear that the Lord of Light is behind it. In a song of ice and fire, there is no longer ice. So fire will reign. Perhaps crops are going to die, perhaps stone men are going to start showing up in Westeros, or perhaps more undeads like Beric are going to be around but in a bad way. By the end of this series, Bran is going to go back and figure out why the Children created the Night King...and determine that for the balance of humanity they need to be created again. First thought is Bran becomes the NK, but I think he's too important to the living for memories so he'll stay the 3 eyed raven. One of Dany and Jon will become the new NK (or NQ), and due to the prior NK's trait of being impervious to fire, my current money is on Dany (believe Jon burned his hand in season 1 or 2).
This is probably crazy and out there but just seems like it could be the crazy twist we've all been waiting for. Finally, I have a theory on who will be a co-conspirator in this NK or NQ creation - Lord Varys. Mel predicted he'd died in Westeros AND he is the most unabashed hater of the Lord of Light due to what happened to him. I can see him be the one pushing the dragon glass into Dany or Jon to make the NQ or NK and then die immediately after. A final sacrifice by Varys to save humanity slash combat his true enemy - the Lord of Light.
Just a point to make about the bolded part: Jon snow is still ice as he's the son of Lyanna Stark, who was a northerner. George Martin also likes to play with words. That said, if you remove the letter "g" from the book titles it would read "A son of ice and fire". That would equal Jon Snow, though we all know his real name by now.
He clearly meant Ice as in the Night King and Fire as in the Red God. The theory being with the Night King killed order and balance in the universe is off, which will cause all sorts of problems. I don't buy that theory at all. Just doesn't fit with the narrative of the books or the show at all.
Martin loves double meanings. I think the title of the book series probably has that double meaning. Ice and Fire could be the Night King and R'hllor but it could also be the story of a person with Stark and Targareon blood. Or it could be both. If I were you guys I wouldn't argue that it is clearly one or the other because it's probably is both.
Thanks, Nick. That's exactly what I meant. Greenshooter, Yes I know Jon Snow is still ice (and so is Sansa, Bran, and Arya)...if I literally was suggesting there were no Starks left, it would show I missed a lot last episode...
The Starks tagline is literally "Winter is Coming"...does anyone think Winter will still be around without the Night King? He literally "brought the storm". Let's see what the climate is like the next few episodes before scoffing at my idea...
Another thought, which someone else had which I cant steal as my own, but is derived from my general idea, is that Jon makes Dany into the Night Queen and that is also his Azor Ahai/Nissa Nissa moment. I like that derivation a bit better than my own. I like this even more because:
Dany's life would literally be A Song of Ice and Fire
We all know Jon's life is a Song of Ice and Fire
And the Night King/Rhollor Song of Ice and Fire idea...
