Remember when Sansa told Arya that Jon be happier to see Arya when they were in the crypts? For some reason I don't think Jon and Arya will have too much of a happy reunion because I think Arya will be more upset than anybody that he bent the knee. Remember, Arya was the one who saw her Robb's mutilated body with Greywinds head attached to his body. Arya knows more than anyone what Robb died for; she saw what he died for. That's why I don't think their reunion will be as sweet as people think.
You may be right, she may be furious at Jon for what he did and argue that he weakened the Starks’ position relative to the two queens. The fact that he was home and King in the North also appeared to greatly affect her so when they meet he won’t be king anymore, which is disappointing. But wouldn’t it also be kind of awesome if she used her lie detector abilities to read Jon and see that he’s not sincere about Dany (love, leadership or otherwise)? It wouldn’t change what he did but it would allow her to see that he’s still loyal to the Starks.
If a Disney princess had night terrors, the story of Sansa Stark might be what woke her up screaming. Often overlooked in favor of her killer kid sister, the elder Stark sibling has had all her illusions about the world, and her safety in it, shattered. But her quiet, innate political shrewdness and emotional strength have enabled her to survive in a royal court that likely would have cost every other member of her family their heads. She’s the show’s best-kept secret.
