It seems the fans are having a little bit of a love-hate relationship with the latest "Game of Thrones" episode. While some think that this was the greatest episode in the show's history, others might not agree, saying how it's full of plot holes and things that don't make much sense. Either way, one can't deny the fact that the last shot of the episode was a real game-changer. Killing Viserion is devastating, but reanimating him brings the game to a whole different level.

Now with a White Walker dragon by his side, the Night King seems unstoppable. Before jumping into theories how Viserion might be killed, let's first clarify what kind of a dragon he is now.

Viserion is a White Walker dragon

To explain it better, let's take a look at the main difference between a wight and a White Walker. And for that, we must go back to their creations. In season four we saw the Night King turning Craster's baby into a White Walker, by putting the finger on baby's cheek. Then, at the end of the "Hardhome" episode, we could see the hundreds of corpses being reanimated when the Night King raised his arms. And since the Night King touched Viserion, it is safe to say that the dragon is now a White Walker. So with that out of our way, let's explore how to kill the beast.

Why is this so important?

Viserion being a White Walker dragon means that he has all their strengths and weaknesses. And since the dragon is not a wight, that means he can't be killed by fire, just like the rest of the White Walkers.

The same goes for a dragonfire as we saw the Night King not being affected by it in the last episode. So that leaves only dragonglass as the only weapon. But there's a catch. According to George R. R. Martin [VIDEO], dragonglass is made from dragonfire, so it might not be as effective since Viserion is a dragon himself. Of course, people can try to shoot this dragon in the eye in the hope that he will shatter to pieces, but according to a well-known YouTuber Talking Thrones, there is another explanation how Viserion might go down.

Talking Thrones' theory

In "Beyond the Wall [VIDEO]" episode we learned that the whole army of the dead is somehow connected. And our characters realized that as they've seen a couple of wights shattered to pieces when Jon Snow killed one White Walker. Later in the episode, Beric Dondarrion proposed a solution -- kill the Night King and the whole army should be destroyed since he is the one who created them all. And according to Talking Thrones, this could work on Viserion as well. In any case, we are going to have to wait for season eight to see.
