THE final instalment of Game of Thrones is set to send fans and Twitter into a meltdown when it airs in the US and Australia on Monday afternoon.

The episode entitled "The Children" has been billed by the show's creators as the best finale on the show to date.

According to showrunners David Benioff and Dan Weiss, it will be the "finest hour" the pair have produced.

They have even admitted that they will be "a little intimidated" about making future episodes that can live up to this one.

But just what is in store for us? We've broken down and analysed the 30-second trailer for "The Children" and put together our theories on what will happen in the last episode.

Bran, Hodor and the Reeds have been continuing on their journey beyond the Wall to find the three-eyed crow this year.

But it seems that they have finally found it - if this shot of a sunlit weirwood tree is anything to go by.

That's the white-wooded tree with red leaves, a symbol of the old gods that the Starks worship. It would suggest that there's going to be some kind of mystical involvement. Bran may finally fly.

Cersei is questioning how much her father really knows about his own family.

For instance, does he know that his twin son and daughter have been at it for years and have produced three illegitimate offspring?

There has never been any question of Tywin Lannister's loyalty to his family but that doesn't mean he's always done the right thing for them. In her rage, will Cersei reveal who Joffrey, Tommen and Myrcella's real father is?

Meanwhile Tyrion is languishing in his cell, waiting to meet his fate.

"The Children" will see the conclusion of Tyrion's sentence, are we about the re-live another Ned Stark-esque death? This a point of uncertainty but surely they can't kill off everyone's favourite wise-cracking imp, can they?

Arya and the Hound have been delighting fans this season with their hilarious exchanges.

These two are the most unlikely comedy duo in Westeros but they have provided some of the show's comic relief this year - and in Game of Thrones a small break from the murder and destruction is always welcome.

But their storyline could not keep going on from one comedy sketch forever. Arya is after all the Hound's hostage, who he failed to sell off after discovering Lysa Arryn is no more.

From the trailer is appears that the youngest Stark girl could find herself becoming someone else's hostage. As long as it is not Ramsay Bolton, it's fine.

Jon Snow has now gone beyond the Wall to find Mance Rayder. He's caught up in another battle with the Wildings and the King Beyond the Wall, who promises to slay "every last man" in Castle Black.

Towards the end of the trailer, Jon appears to have a sword inching towards his neck. Will this be the end of Jon Snow?

We lost Ygritte last week, so this could be it. Then again, will he bump into Bran? This season has deviated significantly from the novels with both Bran and Jon's storylines, so it could be entirely possible. 

The majority of Daenerys's storyline has played out over season 4.

Last week audiences witnessed the exile of Jorah Mormont, who was discovered to have been spying on her for the Iron Throne.

Is the Mother of Dragons now planning on taking her children back to Westeros and reclaiming her rightful kingdom?

Or does she plan to linger further in Meereen while the Sons of the Harpy attack her men?
