4. Jamie kills Cersei!
Oh Yeah! This is an ultimate of all the Fan theories about the Game of Thrones… When Cersei turns mad, Jamie being the Kingslayer, will be taking the credit of slaying the Queen as well! Somehow, that makes sense. With some theories suggesting that there is also a prophecy of Cersei to be killed by a younger brother(maybe that’s why she hates Tyrion), and Jamie also being born after Cersei, he may be that younger brother! The killer brother!
5. Littlefinger marries Cersei
Now, as we know Littlefinger is all behind power! And Cersei being the powerful person now, he may suggest for the bond which will help her as well as he has this huge army… Then they together fight the Daenerys army! Umm… quite possible.
6. Varys is a Merman!
We all know about the speed of Varys’s travel from Dorne to Meereen! How could that be possible? What if Varys is a Merman and that’s, in fact, his motive behind supporting or even being in the great game! He wants to free his men and maybe take the help of dragons to melt the North to have enough water? I don’t know whether this can be true… but yeah, that’s another Fan theory for you!
