Warning, the following post contains a lot of spoilers for the season finale of Game of Thrones, “The Dragon and The Wolf.” If you still haven’t seen episode just yet, we suggest you either seek refuge in a cave to avoid the internet or make your way over to HBO ASAP.

We knew Viserion’s tragic death at the hands of the Night King in “Beyond The Wall” would be a game changer — and in the closing moments of the Game of Thrones finale, we saw just how much of a game changer it was. As Beric Dondarrion and Tormund sat atop the “impenetrable” Wall, and the Army of the Dead marched toward it, an undead Viserion, ridden by the Night King, breathed a blue fire to take the structure down with ease. Then the Army of the Dead marched south.

It was beautiful and terrifying:

But now that we know how powerful an undead ice dragon can be, the question remains, how do you kill an undead ice dragon?

Let’s face it, we have no idea and that terrifies us. For seven seasons before they had an ice dragon, we knew that the White Walkers were a nearly unstoppable force, and definitely something to fear. But, an ice dragon ups the stakes by *so* much. While we technically don’t know exactly how to defeat an undead Viserion, we can certainly wager an educated guess as to how our Westerosi heroes will defeat the ice dragon.

As Jon Snow pointed out during the meeting in the Dragon Pit, wights can be killed by fire and dragonglass:

Who’s to say that undead Viserion can’t meet his end the same way? But then again, if there’s one thing we’ve learned during seven seasons of GoT, it’s that dragons are hard to kill. But Season 7 has shown us two ways Dragons are vulnerable:

and The Night King’s spear.

My thinking is that the these clues — how to defeat a dragon and a white walker/wight — could potentially be the key to defeating undead Viserion. If Gendry can build dragonglass spears and the Westeros army uses the catapult of fire to take him down. Or Drogon and Rhaegal will team up to take their fallen brother down — ridden potentially by Dany and Jon.

This is pure speculation but as the final season of Game of Thrones is AT LEAST a year or so away, it’s really all we can do.
