Possible theories, a recap and everything else in between

My theory...previously expressed to only one other person...

Sansa and Tyrion take the Iron Throne together since technically they are still married.

Ooh, I would love for that to happen... It's been particularly hell for these two.
Although Daenerys and Aegon...

I haven't seen any Aegon appear in the series.

Martin (the author) has stated that there will be a bittersweet ending. With him, you can bet money that means some of our favorite characters are going to die before all is over.

Sansa has never been a fan favorite.

Dany and Jon Snow always have been. As has Tyrion.

And status and treatment of women has always been one of the key issues in Martin's tale.

Therefore, having a woman go from weak to strong, then rise to the throne, but settle for a marriage of convenience with one of the few **good** noble men....well, that's about as bittersweet as it gets.

The writers and producers go write a bunch of other t.v. shows, do comicon appearances, tours, and a million other things, and the finale is actually postponed for 10 years while fans get mad and are told "any day now, just editing," and after 10 years they're told it's going to be a 2 parter with the second following the first quickly, where the first parter is a cooking competition between secondary characters making lamprey pies, and another 10 years pass before the actual finale is teased that it might be coming soon, and then they come out with a movie that is supposed to cover the entire t.v. series that hasn't been finished, and the movie is then said to be coming in 3 parts...

...That's just a guess.

What is Jon's valyrian name? As the child of Lana Stark and Rhaegar Targaryen. Is it not Aegon?
Dear heavens...

Oh the joys of being a fan

Actually Aegon was supposed to be a child Varys secreted to Essos and raised by the name Young Griff.
