Arya is one of my favorite characters and it was great to see her finally return to Winterfell and be reunited with Sansa and Bran. The scene of Arya and Sansa on the battlements of Winterfell was one of my favorites this season. Even though Arya's reunion with Nymeria was short, I still loved seeing them together again. Can't wait for Arya's reunion with Jon in S8 and hopefully she'll also cross paths with Sandor and Gendry.
