If you watch the two official trailers for "Game of Thrones" Season 7 again, you can notice a lot of scenes that we've yet to see. After the first three episodes of this season, we can explain what's going on in several of these scenes, so be careful: potential spoilers will follow!

The trailers

You can watch again the 'GOT' season 7 trailers below:

Beyond the Wall

The trailers feature several scenes beyond the Wall with Jon Snow, Tormund Giantsbane, and several other characters. According to what we see (check the second picture of the photo gallery by clicking on the camera icon above) Jon Snow will lead an expedition in the deep, deep North.

A dozen men will go with him.

As you can see from the third picture of the gallery, Jon, and his companions will be in mortal danger. The image indicates that Jon, Tormund, and others will run for their lives at a certain point. Why are they running? Well, you know what lies beyond the Wall: the White Walkers and their undead army.

In the next episodes, Jon and his companions will be surrounded by a legion of wights, and someone (maybe Jon?) will fight a White Walker with his sword (check the fourth picture). In the this article's main picture, you can see Jon, alone, standing in front of a legion of wights. Since Jon is still in Dragonstone at the moment, we can speculate that all these scenes will be featured in the last two episodes of season 7.

Arya and Littlefinger in Winterfell

Arya will reach Winterfell in the next episode of 'GOT,' as we saw in "The Spoils of War" promo video. In the fifth picture of the gallery, the young Stark is looking for something (maybe a bed). What is she looking for? We have no idea. But this scene may be aired in episode 4 or 5, so we will find out pretty soon.

We've also yet to see the well-known scene with Littlefinger creepily spying someone from the shadow (sixth picture). Who is he spying? Sansa, Arya or Bran? Must be one of the Starks.

Epic Jaime is epic

And now let's have a look at the epic battle scene which will probably be featured in the very next episode of the show. Dany lost her allies as soon as she landed in Westeros and the Unsullied are now stuck at Casterly Rock.

"Enough with the clever plans," the Mother of Dragons says in "The Spoils of War" trailer, and the seventh and eight pictures of the gallery show what she's going to do next: attack the Lannister army with her Dothraki horde.

Judging by the flames on the battlefield, Drogon will be involved in the battle, and, at a certain point, Jaime will charge against someone. As you can see from the ninth picture of the gallery, there is going to be a lot of flames in the scene, and Jaime and Bronn are going to risk their lives in the battle.

The Hound

In the last picture of the gallery, you can see Sandor Clegane ready to face someone with his sword. That's a very interesting scene, especially if you consider where The Hound is probably located.

The ruins in the background suggest he's at the Dragonpit. The Hound's journey is not going to end in the north. In the last episodes of season 7, he will be ready to draw some blood in King's Landing's nearby!

"Game of Thrones" season 7 episode 4, "The Spoils of War" airs on July 30, on HBO.
