Game Of Thrones Season 7 Spoilers: 17 Scenes We 100% Know Are Happening

3. Benjen Returns (For A Big Fight)

The away party that has been shown in the trailers - and who we now know the identities of thanks to that last point - head into the frozen North on their special mission, and deep into wight occupied territory.

It seems they'll first meet up with Wildlings (possibly to try and recruit them or save them), and then it's onwards to find themselves some White Walker scalps. Thanks to some images of the sets, it looks like we're going to see Hardhome II with a stunning battle sequence set on a frozen lake.

This scene required 300 extras, so it's going to be a hell of a spectacle. It also required the reappearance of Benjen Stark, as he was spotted on the Irish set along with other key players...

So presumably we're going to see an emotional reunion between Jon Snow and his uncle (who definitely feels like dead meat - though, can he even be killed?) and a huge bloody battle between these heroes and the undead hordes.
