Headcanon: Although all of Mike’s alters would like to have control over the body, Svetlana has more or less given up. Even if she were to be able to be the main personality, the thought of having to live out life in a man’s body sounds just as enslaving as her current situation. She puts all of her energy into her gymnastic skills because it’s better to do that than to brood about her predicament- stuck in a man’s body with five men until the day Mike dies.
