YES. Zuko's fire and, obviously, Jack's ice were both huge for her, seeing firsthand that people can do things similar to her. But also enormously instrumental in her coping and self-acceptance has been Jessica, who told her about the X-Men and how superheroes are sometimes lauded in her world and even put on magazines and posters, and that idea of a world where people, even if not all of them, celebrate people like her was seriously an epiphany. And then the most recent thread I linked where her powers came back while she and Jess wound up fighting a fire has really helped turn her around. Finding there's a way she can help people with her abilities and that this is a thing people just do makes her so much more at ease, like she's finally found a purpose other than ruling Arendelle.
