Game of Thrones season 7 episode 7 trailer: Finale's tense wight summit teased in HBO's YouTube preview

The fallout from the expedition north of the Wall

HBO has posted the trailer for the final episode of Game of Thrones season 7, seeing Cersei, Jaime and Tyrion Lannister finally come face-to-face once more.

So as not to give too much away, there is less narration in the preview than usual, but the following scenes are teased:

Greyworm is seen leading the Unsullied as they create an imposing presence outside King's Landing.

Tyrion, Varys and Theon look on from the boat carrying Jon and Daenerys as it arrives at King's Landing.

The Dothraki join the Unsullied and bolster the Targaryen presence.

Sansa walks the battlements of Winterfell - she looks ominously Grim Reaper-esque, perhaps hinting at death for either herself or Arya.

Theon falls to his knees on the shore.

Jon, Podrick, Tyrion, Jorah, Davos, Brienne and Theon enter the Dragonpit and prepare to introduce their wight prisoner (The Hound doesn't seem to be among the party, so I guess Cleganebowl is on hold?).

Cersei and Jaime meet them, and the atmosphere looks pretty tense (notably, Daenerys isn't seen, though it may be that she enters the scene later).

Jon Snow closes the trailer saying what he's been saying pretty much constantly for two seasons: "There's only one war that matters and it is here."

Note however, that quote's potential double meaning...

Game of Thrones season 7 concludes on HBO, Sky Atlantic and through NOWTV on Sunday night.
