SPOILERS AHEAD
First, before going into any theories about next episode, a few words about last episode.
Arya survives! Just not exactly like either of the theories in the previous post suggested. From the look on Jaqen’s face at the end, it appears that he had been trying to prepare Arya with the necessary skills to survive out in the real world, rather than actually becoming a Faceless Man. At least, I like to think that. It’s really tough to read Jaqen, which I guess is the whole point of his character in the first place. Sure hope this isn’t the last time we see him.
We have really little to go on here other than there’s going to be a big battle, that Jon doesn’t want to be brought back if he dies, and that Davos sees something behind him while he waits to light a signal fire.
So, I’m sitting here thinking, what would make this episode great? Well, Ramsay Bolton dying would be #1 on the list for me. Hate that guy. What would be a great way for this to happen? Jon Snow battling him? Nah, nothing exciting about that. Sansa striking him down? Yeah, satisfying, but nothing really big.
A good story has characters getting into deeper and deeper trouble, and finally find a satisfying way out of all the mess.
What do you think of the following scenario?
Jon and Ramsay’s armies face each other and start the battle (duh…we see that in the preview). Thing go OK for Jon at first, but as things progress, things start turning in Ramsay’s favor. Just as things look really grim, Ramsay realizes he’s being attacked from another army. Who’s doing the attacking? The Night King’s army, with all the men from The Wall as part of his army. Ramsay and the rest of his army get killed in a big, big way. Of course, they’d have to get around Jon’s army first…
I know it might be a bit early for this to all happen in the story, but seeing Ramsay taken out by the army of the dead would sure be memorable.
