Even though the air date for the "Game of Thrones" season seven has not yet been confirmed, fans of the show have already come up with many theories about what will possibly happen in the next season.
Season six of "Game of Thrones" ended with Jon Snow becoming the King of the North while Cersei Lannister massacred her enemies, eventually being crowned Queen of the Seven Kingdoms. In line with this, Cersei may not be happy knowing Jon's new reign and might sabotage it.
There have already been theories by the fans that Cersei might be more ruthless in the upcoming season seven of "Game of Thrones." According to Movie News Guide, she may even send Sir Robert to kill Jon Snow, assassinating him so that he will not get any chance to take her chances of getting to the Iron Throne.
Another theory for the upcoming season of "Game of Thrones," is that Littlefinger will have Sansa Stark turn against her brother, Jon Snow, to get her the control over Winterfell and marry her after. He is initially planning to enter a war against Daenerys and Cersei. However, since the series will only be until season eight, such events might not happen due to the limited time available for the acclaimed series to fully tackle the storyline.
According to Movie Pilot, another theory is that Jon will form an alliance with Daenerys by marrying her and they will take the throne together. Even though they are technically related, it may just be a political marriage that will occur just to own the throne. Another theory also is Bran Stark spreading the real parents of Jon snow who are Rhaegar Targaryen and Lyanna Stark.
There have already been a lot of theories lined up for the series but any confirmation has not yet been released. Fans will now have to wait for the series to air its seventh season by summer 2017.
