A Change of Heart - S3.E37

Minx decides to step up her pursuit of Rio by helping him design a synthesizer. While he's grateful for the help, he makes it clear he's not interested and the two separate in a huff. This changes when Minx gets caught in a dangerous current at the beach and Rio dives in to save her. Minx is so grateful that she vows she's going to change her ways. She becomes nice yet insecure, offering her help to Rio, the Holograms, and the Starlight Girls after Riot and Rapture kick her out for acting strangely. But her efforts to help only disrupt everyone's lives and they are forced to tell her to back off. Minx becomes so offended that she reverts to her old self - she throws the synth she built for Rio out the window, shoots everyone with a squirt gun, and rejoins the Stingers. Rio and the Holograms hope that at least part of this experience will stick with Minx, but based on her attitude at the Stingers' next concert it doesn't look like that's going to happen.
