[It's the only lesson she could take after years of having those thoughts and fears haunting her. Her parents tried their best, but they didn't do it well, the words they gave her, the lessons, the advices, the trust, nothing of it worked, nothing stopped the ice and the coldness. They sacrificed their lives and ruined Anna's life just for Elsa's sake, if only they had sent her away right from the start, the gates wouldn't have had to be closed, no one would have suffered but her. Ultimately everything turned alright anyway, now Arendelle's gates will always be open and even if Anna's judgement isn't the best at times... She will learn, and she's not alone even if Elsa could not approve of it.]

I see. So they left and never returned, I suppose that they can't exactly be found either even if one tried to search for them, right? I wish that the world I come from will have the same resolution, with people working together in harmony rather than using each other.

[She will never know, thought. She didn't wish to return but now that she understands how little place she has there, she's even more set on the idea. Even if she returned she would remain in the North Mountain- no, she can't stay there either, she must go away, further, where no one will ever be able to find her no matter what. She will find a way if she's forced to return, until then, this world does it well enough for her.]
