This post contains frank discussion of Game of Thrones up through Season 7, Episode 7, “The Dragon and the Wolf.” If you are not caught up with the season finale, now is the time to leave.

We have a long while yet to wait until Season 8 of Game of Thrones. The final season of the HBO series hasn’t even started shooting yet, and there are some rumors that given the time it will take to make six super-sized episodes, the eighth season won’t premiere until 2019.

Still, we obviously can’t help but start wondering now what will happen to our favorite characters in the home stretch of this series. It’s possible that George R.R. Martin’s next book, The Winds of Winter, will come out during the long off-season and provide us with many more juicy clues about the fates of the Lannisters, Starks, and the rest. (That’s certainly Martin’s hope, anyway.) But until then, there are, believe it or not, a few remaining book clues that should help fans know what to expect in the final season. Careful: here be dragons, and some book-informed speculation.

Jon Snow, a.k.a. Aegon Targaryen, and His Aunt Daenerys

If the way that the show juxtaposed Dany and Jon consummating their flirtation against the reveal that they’re related didn’t give you the sense that this relationship won‘t end well, then maybe some behind-the-scenes interviews will do the trick. Show-runner D.B. Weiss says the fact that Dany and Jon are related will “inevitably, if not drive them apart, will create real problems in their relationship.”

As for Jon’s (do we really need to call him Aegon?) claim to the throne, Emilia Clarke confirmed to Entertainment Weekly that Daenerys is not into sharing: “I’ve worked so hard, I don’t want to share that throne. No. The throne’s big enough for one dragon bum, and that’s mine. That’s it!” This would seem to confirm that Jon will play out the competitive role designated for a different Aegon Targaryen in the books. (It’s complicated; you can read about it here.) “It could be them walking off into the sunset,” Kit Harington speculated of the future of Jon and his sexy aunt. Or “it could be them killing each other.”

But before it comes to all that, Jon will probably ride a dragon.
