We are still 5 months away for season 7 of "THE GAME OF THRONES". There are many questions which are still unanswered. Winter has already come and is one of the reason why the production schedule is delayed. Fans can't wait until their questions get answered. So some of them have came ahead with their own theories about season 7.
Here are some of the theories which are possibly going to be proved in the coming season:
1) TYRION LANNISTER IS A TARGARYEN.
This is my favorite theory. Tyrion is undoubtedly the most loved character. Almost the entire Stark family is dead, but he is still going strong. It would be the biggest surprise for the fans if he turns of the third head of the dragon. We don't want him to end up as the god of tits and wine. It would be so amazing if Daenerys, Jon and Tyrion are the three heads of the dragon.
It comes for another theory that the mad king had an affair with Joanna Lannister. When Tyrion was about to kill Tywin, his last words were "You are no son of mine". Also, in the scene of Tyrion with the two dragons, he tells them about how he always wanted a dragon when he was a kid. This might be because he is a secret Targaryen, otherwise why would a Lannister ask for a dragon on his name day?
Jon Snow, another favorite character might be Azor Ahai, the warrior of light. Now that R+L=J is finally confirmed, the next possibility is he might be Azor Ahai. Melisandre's prophecy states that Azor Ahai will have the blood of dragon and he will be reborn in smoke and salt. Also, Jon Snow picked his Night's watch post over Ygritte, which ties on to the original Azor Ahai and Nissa Nissa, wife of Azor Ahai (He sacrificed her to create his famous sword, Lightbringer).
3) BRAN IS ACTUALLY BRAN THE BUILDER.
Bran The builder was the man who created winterfell and he raised the wall 8000 years before the on-going events. There is a possibility that Bran and Bran the builder are basically the same person because Bran can travel in time. Bran can travel in past and future, he can influence events and warg into people. Maybe he went 8000 years back and built the wall to keep the white walkers away.
Also, as the old nan mentions, Bran's favorite stories are the ones of Bran The Builder.
4) THE WEDDING OF ICE AND FIRE.
Thanks to that desperate fan who clicked the photo of Jon and Dany together which proved they are finally going to have a scene together in Season 7. Since then, their wedding is considered to be another possible theory. Daenerys is the dragon queen and Jon is the newly crowned king in the north. They can be unstoppable if they are together. Also, as Tyrion said at the end of season 6 that she might have to form alliance and wedding is the best option to form alliance.
5) SAMWELL TARLY HOLDS THE KEY TO EVERYTHING.
At the end of Season 6, Samwell Tarly got into Citadel. So now he has access to the entire literary history of the world. Many people think that this might turn out to be something bigger. He is quite a bookworm and now that he has access to the biggest library of Westoros, he might unravel many mysteries like how to put an end to the white walkers or a key in making of Valyrian Steel.
He might turn out to be an important character who will help Jon in defeating the white walkers.
There are many other theories like Ned Stark might be alive, Varys is actually a Merman, Sansa is pregnant with Ramsay's child, Jamie will kill Cersei, a dragon living under winterfell, Missandei is a faceless man, etc. Lets just wait for Season 7 and know what's going on in that freaking old cruel mind of GRRM.
