After over a year long hiatus, "Game of Thrones" is finally back with its seventh season. Season 7 episode 1 aired on Sunday and what a premiere it was. Every scene was done so well that they reminded us in an instance why we love this show so much. Spectacular dialogues and amazing story lines picked us right where we left off at the end of season 6.

And while many fans are focusing primarily on Dany and her long-awaited return to Westeros and that mind-blowing Arya scene in the cold opening, there is one interesting scene I specifically wanted to talk about in this article.

To be honest, I can't remember watching a scene that gave me more shivers than this one except for the last few seconds of the Hardhome episode back in season 5. Here, I am talking about the scene where Sandor Clegane a.k.a. The Hound had his first vision in flames. Although the full premiere was one big teaser of things to come, this scene teased the climax of this season. So without further ado, let's see what is it all about.

The scene

This sequence opened with Sandor Clegane traveling north along with his companions from Brotherhood without Banners, Beric Dondarion and Thoros Of Myr. Soon, they took shelter in an abandoned farmhouse. It wasn't until they found two skeletons inside when the Hound realized that he had already been here with Arya and that the skeletons belong to the farmer and his daughter whom he robbed back in season 4.

The highlight of the whole sequence was the moment when Thoros of Myr invited the Hound to come closer to the fire and tell what he sees. After initial resistance, Sandor Clegane finally looked deep into the flames with a facial expression of a terrified man.

What did Sandor see?

The flames showed the place where the Wall meets the sea and the castle there, Sandor Clegane said before adding that the thousands of dead are marching past a mountain that looks like an arrowhead.

The castle is most likely Eastwatch by the Sea, one of the Night's Watch castles, while the mystery of the mountain that looks like an arrowhead remains unsolved. Of course, we can't help but notice the apparent reference to Sandor's brother Gregor, but in my opinion, there is going to be an actual mountain near the castle.

What's also worth noting is the official HBO transcript of the scene and the line: "The waves are frozen" that wasn't mentioned in the show.

The reason why this line didn't make it the final cut remains a mystery. In my opinion, this is the crucial detail that reveals how the army of the dead will pass the Wall.

Looking at this scene, there is no doubt that we can expect season 7 to be the most exciting season of "Game of Thrones" so far.
