Game Of Thrones Theories: 15 Epic Season 7 Moments Still To Come
6. Hardhome 2: Eastwatch Boogaloo
Ultimately, even without knowledge of the set leaks, this season is heading towards the North. Jon has already identified Eastwatch By The Sea as a key strategic position as he sent Tormund up there to defend it (an opportunity he accepted with typical relish), so there's no way we won't see something go down there.
The trailers also showed a fan-baiting union of great characters with Jon Snow, Tormund, Beric Dondarrion, The Hound, Thoros and Gendry teaming up to go beyond the Wall and fight an army of wights. Judging by their clothing, it looks like the Night King will successfully beat (and revive) Tormund's Wildling army in what promises to be a battle on the scale of Hardhome, with action centred on the frozen sea and presumably some eye-catching new additions to the wight army.
It's not going to end well for that party, and sadly we're likely to see the end of Beric, Thoros and Tormund at least, but they will at least go down as they would like to.
