>>116415473In the Incredibles Comic, Violet discovers that one of her classmates is a super. Understanding how superpowersr can make one feel isolated, she reveals the truth to her and the two of them become friends. It's then revealed that Rose's dad is a supervillain, and that she uses her own powers to assist him in his crimes. The two of them agree to go their separate ways, but when Rose's dad attacks the school, Violet and her family team up to arrest both of them. As far as I know, that's the last we see of her, despite her knowing Violet's secret identity.
In that edit, they just made the two of them gay, because the sexual tension between the two of them in the comic was honestly pretty thick.
