And most shocking? Despite Arya choosing to go head to head with Daenerys, she will purposefully lose the fight.
The conspiracy, which was posted on Reddit, reads: "I believe that Arya is headed to King’s Landing to attempt to kill Dany. I believe Arya will intentionally fail this assassination, forcing Dany to kill her, in full view of Jon."
"This will allow Jon to finally see Dany for what she is. Jon kills Dany…And there you have it, the Prince that was Promised."
"Arya’s real target is Dany – the Starks’ values have always centred around protecting family. Arya and Sansa know that Jon is in danger."
Although the theory claims Arya will sacrifice her life, the fan believes Jon will kill off Daenerys, although another theory predicts Jon will die.
The post continued: "Jon seeing Dany for her true nature, he has to kill her – it’s the only fitting ending. He doesn’t care about the throne but he cares about his people and Dany sitting on the throne is no better than Cersei or the Night King sitting there."
At this point, who really knows what will go down.
