SPOILER ⚠️ • • THIS EPISODE OMG!! And this scene omg I cried!! 😍😭 I'm so glad she had her little reunion with Nymeria! She looked huge and beautiful! And in case you were wondering what the "That's not you." sentence meant. Here you have your answer. It was a reference back to when Arya said that to her father Ned. Nymeria has been with her pack in the wilderness for so long and now belongs there. It wouldn't be her if she was anything different. Just like Arya isn't meant to be some lady.
