This article contains spoilers for Season 8, Episode 5 of “Game of Thrones.”

“Game of Thrones” fans don’t just watch the show, they theorize. About everything. About prophecies or would-be prophecies from even the most minor characters. About plot lines and details from the books that aren’t even hinted at on the show. About unresolved mysteries and the unifying Theories of Everything that may explain them, no matter how outlandishly.

Now that we’ve nearly reached the end, here are a few remaining theories that may help clarify some of the show’s remaining mysteries or predict its final moments, in order of plausibility:

The Prince or Princess Who Was Promised

Azor Ahai was an ancient hero whom followers of the Lord of Light believe is destined to be reborn as the Prince or Princess Who Was Promised. Melisandre believed this was Stannis, then she believed it was Jon, then she seemed to believe that Jon and Dany together might have something to do with it. The rest of the Red Temple priests and priestesses have been preaching all along that this is Dany.

According to prophesy, the revenant Azor Ahai is meant to prevent the Long Night, just as the original did thousands of years ago. One could argue, then, that Arya fulfilled that role, having killed the Night King. Still others believe that it will be a child born to Jon and Dany if she’s not as infertile as she thinks. (And if Jon ever decides he’s O.K. with incest. And if she lives long enough to find out).

But Azor Ahai had to sacrifice his beloved, Nissa Nissa, in order to defeat the darkness last time. Prophecy says the coming hero would have to do the same. If Jon is the new Azor Ahai, that might mean he would have to kill Dany. He certainly has reason to now.
