Watching Sable, I see a coming-of-age story. Sable is going to do the gliding. Seems like you get a mask? Okay. You need to get permission from the grown-ups. They see you as adult, you get to do the coming-of-age.
Makes me think: What if they never do? What does a story arc look like for a character who's denied their coming-of-age because the adults don't see them as adult?
