A theory about Miss Heed and how she met Goldheart
While we wait to finally see that famous meeting, I surmise that Cecilia (at the time) was an easy target for kidnapping; she had no qualms about flaunting her wealth, making her vulnerable. Someone might have heard about her, or she could have angered someone with connections. It is unlikely she was chosen at random during a villain attack and rescued by Goldheart—though since he was already famous, she likely fell for him, feeling like a fairytale princess, especially with crowds surrounding them both.
There is also the possibility that she paid to meet Goldheart (inspired by the theory regarding Justin Bieber's wife) or even paid to be attacked in Goldheart's city. After all, if Cecilia ever thought becoming a villain was an easy way to get her crush's attention (like Catwoman and Batman), a golden opportunity arose when she met Kenning and his formula. She decided to steal the formula from her only friend—at a school where she likely survived bullying thanks to her money but was otherwise ignored (since there were people with ridiculously more wealth)—and chose to run away. Upon arriving at Peace with "her idea" for the formula and trying to catch Goldheart's attention—since I doubt the hero would remember her among the masses he saves—she managed to become an assistant or receive training from the most famous hero and rise through the ranks quickly.
Heed isn't just a pretty face; she knew how to lie to Peace and everyone else. She spent a long time refining the formula, and I have no doubt that people questioned her and wondered why it was taking so long.
