Winter is coming and so are the fan theories! Ever since the end of Season 7 where viewers watched as the Wall collapsed and the dead came pouring in, people have been trying to figure out what could possibly happen next for everyone in Westeros.
From guessing who the Valonqar is to who is truly the Prince That Was Promised, speculation runs rampant. Really though... I wonder who is Game of Thrones' Chosen One?
Now, there is one theory
Drawing from A Game of Thrones, the theory pulls at Jon's words made in the first chapter of the book when he warns his little sister to not neglect her studies.
Martin is known for hiding foreshadowing clues as to the fate of his characters even early on as book one, however, it could be just an over-analysis done by avid readers. Either way, you can't deny Jon's words are very foreboding (and pretty chilling, no pun intended). Winter has come to the North, her home, and she has indeed run away from her training in Braavos with the Faceless Men. What's more is Arya owns a sword named Needle, a gift from Jon from Season 1 that she uses constantly in fights... and spring will come after the great battle.
Jon's words related to the person she had run from carrying out punishment. If this is truly foreshadowing and if punishment may be coming for her, the theory supposes a Faceless Girl will come for Arya, as there was a casting call for a new female character to be added to the ensemble for Season 8.
The night- as well as the future- is dark and full of terrors... and we all have to wait a year longer before Season 8 returns to bring about the end.
