Game of Thrones season 7 trailer decoded - 'The Great War is here'

But when it comes to Game of Thrones nothing is too simple, so here is a short analysis on Game of Thrones season 7 trailer:

1- Cersei vs everyone

The trailer shows, Lannisters 'who count' still hold the king's landing, with Cersei sitting on the throne and her brother-cum-lover Jaime Lannister standing by her side surrounded by enemies.

The enemies include Daenerys Stormborn, the king in the north Jon Snow, Arya Stark and Sansa Stark, as well Euron Greyjoy and the Martells and Tyrells.
Basically, Cersei Lannister is royally in danger, though she's putting on a brave front

2- I was born to rule the seven kingdoms: Daenerys Stormborn,

In the trailer, the mother of the dragon is seen saying that “she was born to rule the seven kingdoms”. Although the odds are favoring her, given the army as well dragons by her side, but to rule the seven kingdoms she still needs to destroy Lannister and by Lannister we mean Cersei.
Not just this, but there is one more question, will Daenerys Stormborn make Jon Snow the ruler of seven kingdoms, after knowing his connection to her brother Rhaegar Targaryen or not?

3- The king in the north - Jon Snow

In the last episode of season 6, Jon Snow becomes the King of the North. It seems as if Little finger knows the truth about Jon Snow being Lyana Stark and Rhaegar Targaryen's son. He is likely to use that against him in season seven because Jon is clearly not a stark but a Targaryen.

Maybe that's why he finds himself at the receiving end of Jon Snow's wrath in the trailer, as the former Lord Commander of the Night's Watch grabs the squirming schemer by the throat.

4- The great war is finally here

While everyone is thinking about seven kingdoms. Jon Snow's only concern is White Walker because he knows the great war is finally here.

5- Last but not the least, Arya Stark is coming home

Last season, Arya Stark said that she is coming home after avenging her brother and mother. The trailer gives a glimpse of her as she looks poised for a full-fledged Stark family reunion. She is shown riding through the snow, which indicates her homecoming. From the look of the trailer, Arya made it back home. She looks under her bed in search of what Enemies? Or a place to hide?
