Noting that the animated character has “a big personality,” Miller hopes the audience could learn some lessons from her, given that she now has a voice.

“I want them to be able to hear her personality and be able to watch her and laugh and smile and be happy,” she says. “I want them to feel empowered because she’s an empowering character. She has a lot of representation. She represents confidence and poise and being yourself. So I want people to be able to have all of that and take that away from Qai.”
