Arya and Sansa Stark are finally reunited for the first time since Game of Thrones Season 1. But the sweet reunion took a dark turn pretty quickly. In “Eastwatch,” the two sisters still don’t exactly get along after all this time. However, their disagreement now is over something very different.
In the episode, Arya watches Sansa very closely as she rules over the North while Jon Snow is in Dragonstone. Arya sees her sister listen to people complaining about their absent brother without really defending him. She notices how oddly close Sansa and Littlefinger are and tries to uncover his true intentions.
Arya’s actions may seem like part of the plan to finally have someone take down Littlefinger. But what if it’s leading to a heartbreaking ending for Arya and Sansa? Here is the theory explained with seven important details.
1. Theory: Arya’s ending may be to kill Sansa and finally see her thirst for revenge ruin her family
The youngest Stark daughter has been motivated by revenge for quite some time now — so much so that she has made a list of all the people she intends to kill. As an audience we have been rooting for her to be successful, but what if that is a mistake?
Now she is suspicious of Sansa and Littlefinger, but she is obviously being misled. My theory is that Arya kills Sansa because of this, and it could be a terrible wakeup call for Arya, revealing that her most powerful aspect as a character is actually what leads to her tragic downfall.
