[She nods at his first words but falls silent at the next ones. Did she want to go back? No. What for? There was nothing in Arendelle for her anymore, all she had was the north mountain and her ice palace, and she could remake her palace anywhere else. If she's going to be alone, what's the difference here or there? It would be better to stay here, there she would still be under the risk of someone chasing her, finding her by chance or on purpose. And what then? The only thing that would wait her would be a dungeon... Or a fire pyre.]

I do not want to go back. Or rather, there's nothing for me to go back to. All that I have back in the world I come from is an ice palace that I made, and which I can remake anywhere whenever I want.

[As proved when they found the island she was in.]

Still, rather than who may wish to return or not, there's another kind. Did you see it? A message from someone insisting on people giving up the shards and destroy them or hide them away forever.

Someone who doesn't want to return won't have anything against those who want, so long as a way for them to not be affected is found. But that person didn't seem to be like that.
