Okay my final predictions that you don’t care about. Jon dies. He's the "hero" and heroes should die.
Dany will kill him. She then takes off to Winterfell to kill the remaining Starks. Meanwhile, Arya, and Tyrion, who realizes that Sansa is vulnerable, got a head start back as well.
Dany gets their first though. The dragon begins it’s carnage.
Bran is put on horseback in order to make his escape and maneuverability better—a wheelchair ain’t that good for that. At some point, Dany has Sansa cornered. It cuts to Arya still riding back. Not in time. Tyrion still on a ship, Winterfell in view, but not in time. The dragon is about to scorch Sansa when Bran, out of nowhere, on horseback, uses a short bow to kill the dragon as a nice surprise and to pay homage back to season one when he was told by Tyrion (I think) that he can fire one from atop a horse. The short bow will shoot some sort of arrow made of dragon glass or Valyrian steel or a poisoned tip or something. I recall the scene in season one and how Bran seemed surprised that shooting from horseback was possible.
Dany will then go even further off the deep end. Her last baby is dead. Sansa will dip out of view and Dany will “hunt” Sansa for 10 minutes or so on the show. A little cat and mouse. Tyrion will have returned by now and will approach Dany and be overtaken by her surprisingly somehow. Tyrion is very vulnerable now, and Dany, ******* crazy by this point, will attempt to kill him and Arya arrives out of nowhere and kills her. The eyes prophecy is fulfilled.
Sansa will be then be queen. Arya will be her Mountain. And Tyrion will be Sansa’s Varys.
It'll end with Sam writing all of this down for historical purposes—stole this part from online article I read and thought it made sense.
Something like that. Bran on horseback will come into play. Or should.
