On Game of Thrones Season 7 Episode 6, Dany finally learned the truth… the very hard way:
The White Walkers are real. The Night's King is very real.
And, yes, it is possible to kill a dragon.
How will these revelations impact this Sunday's Game of Thrones Season 7 finale?
It appears as though Jon Snow and his friends will go through with their non-sensical plan to convince Cersei of these same truths by presenting her with their kidnapped Walker.
In the following trailer, Cersei and Jamie Lannister receive Tyrion, Jon Snow, Gendry, Theon Greyjoy, Jorah Mormont, Davos Seaworth and Brienne of Tarth in the ruins of Dragonpit in King's Landing.
We don't see Dany at this meeting, however.
"There's only one war that matters and it is here," Jon Snow warns Cersei, who previously hinted she could see a benefit from a short-term alliance with those seeking her Throne.
To what end, we do not know.
There's also a shot of Sansa in the preview, as we're likely to get a conclusion on the finale to her annoying feud with Aria.
Elsewhere: neither The Hound nor The Mountain appear in the teaser, but fans are speculating that the finale will result in the long-awaited Cleganebowl, a rumored fatal clash between the two hulking siblings.
Weeks ago, in the the second trailer for Season 7, viewers saw The Hound draw his sword in the same Dragonpit seen below.
So there's one more development to potentially look forward to.
Check out the promo now and ask yourself the obvious question:
Who will die on the finale?
