Most of what follows is speculation, but if you’re especially Game of Thrones spoiler sensitive, now is the time to leave!

We’ve seen him glare, we’ve seen him conduct icy baptisms, and we’ve seen him shrug, but we’ve yet to see what the Night’s King from Game of Thrones looks like in a real fight. He waged (and won) the Battle of Hardhome without even lifting a weapon. (Unless you count those frosty guns.) But all that is about to change in Season 6. New behind-the-scenes footage from Game of Thrones reveals the head White Walker swinging an ice sword.

Granted, that’s a jokey swing for the camera, and the King has his weapon sheathed (on his back) in this shot from the original Season 6 trailer.

But still, it’s very likely we’ll be seeing that swinging sword in action very soon. The bigger question is who will the Night’s King be swinging at? A tantalizing bit of phrasing in a recent interview with Game of Thrones producer Bryan Cogman, has some fans thinking that the White Walkers will be part of the big Season 6 battle: “Hundreds of human soldiers on one side of a field, another army on the other side, and then there is a clash that is highly tactical, yet character-driven, and shown from start to finish—a ‘proper battle,’ as Cogman put it.” Human soldiers on one side? Does that mean the Night’s King will be on the other doing battle with the Boltons, Starks, and more? Unlikely. That little bit of verbal trickery is probably the writer dancing around these other inhuman participants in this season’s big battle.

And in fact, other behind-the-scenes Season 6 footage of wights and White Walkers indicate that the frozen menace is going north, not south. You can see them getting prepped and groomed in the root-filled cave of the Three-Eyed Raven.

So are the Night’s King and his army coming for Bran, Meera, Hodor, and the Three-Eyed Raven? When we saw Bran and the Night’s King occupying the same shot in the trailer, most of us assumed Bran was the one doing the traveling via vision. And—as with anything Bran-related this season—we should consider the probability that any and all of these White Walker scenes are just a dream. Maybe Bran has a vision of the White Walkers invading the cave and that prompts him to pack up and leave? Or maybe, just maybe, we’ll see a real showdown and find out if Bran’s ability to warg (e.g., hop inside Hodor’s body) works on the White Walkers as well.
