If you read Errant, you'll hopefully pick up on the fact that Rekki is not intended to be read as just a badass action chick. It'd be better to describe her as an ordinary lass with deep insecurity issues who really wants to be a badass action chick.
Rekki has a good heart and she is capable of being a heroic person and a great leader; she's extremely brave, takes initiative, makes hard decisions and supports her friends. Her weakness is her deep need for validation from authority to feel worthy. Having been a tomboy kid rejected by more traditionally feminine groups, she developed a mindset of "I'm not like other girls" and so got the community and acceptance she needed from people who celebrated her for being tough, scrappy, liking swords and not showing "girly" or "soft" emotions. This left her wide open to be manipulated by an opportunistic narcissist.
Urien has encouraged Rekki's worst, most incorrect belief about herself: That she's only worthwhile, worthy of love or even notice if she's strong, powerful, famous and a winner. She needs to learn that the thing people like about her isn't that she's a superhuman knight who can throw a car; it's that she's an earnest, caring person who tries her best, steps up to a challenge and takes responsibility for her mistakes.
