Growing up is realising that Sofia was just an 8 year old girl who had too many responsibilities and was pressured by adults to save her new family and a kingdom and realm she now has to take care of and protect and people have high expectations of her, and that she was never given any real time to grieve her missing (most likely dead) father who only passed away like a year before her mother's remarriage and she is a child with trauma and doesn't want to bother people with it or tell anyone her secrets because they might put her in danger. She is a prodigy in just about everything she tries and isn't used to the idea of failling or not getting the hang of things quickly.
Sofia is also constantly betting her own life or being forced to negotiate the lives of her family since she was 8. She was betrayed by 4 adults, 3 of which were her teachers and and 3 of them are redeemed. She watched two people be murdered and a man waste his life away. Her brother being distressed and angry because he wasted his childhood preparing for a position he was never going to get because their grandmother and aunt lied. She watched the reason the twins were born and the queen was killed. Has been trapped in the middle of no where multiple times. Her sister stole her amulet. She saved the world multiple times. And her friends were toxic to her for being better than them at a game and trying to help a girl out. Was tricked by Cedric into cursing the entire kingdom to sleep. Is very protective and suspicious to anyone who even looks at the Amulet. Was given a position that constantly puts her life in danger and told to protect an entire realm filled with like 50 kingdoms. Must watch or read peoples lives no matter how gory in order to give them an ending weather it's sad or happy as long as it's an ending. Is blamed if things go wrong because of an adult. Isn't believed even if she's right. And none of the adults listen to her and always underestimate her.
This child needs a hug, therapy, sleep, and should just go play Dazzle all, Flyer Derby, or Ice dancing, go back to the Buttercup scouts, do her homework, practice magic, and play with her animals.
