I feel like a lot of people, especially fanfic writers, miss the fact that Stephanie's trauma is so much more than an abusive father. Her trauma is not only that her father used to lock her in the closet when she was a child, but also that it most likely happened several times in the presence of her mother who was too scared to help her, or came home after her father had already left and did not hear Stephanie's screams because she was Too high from drugs. Her trauma is not only from Batman telling her to go home, but from him actively isolating her from Tim and Cass, telling them not to go near her. Her trauma is not only from the fact that she became pregnant and had to give up the baby, but also from the fact that the baby's father, who was several years older than her, was not around, and had the courage to show up later and suggest that they get back together. Her trauma is not only that the father of her baby was an asshole, but also that she was probably pushed into this relationship out of complete desperation for love and recognition that she didn't get from anyone she knew, and there was no one around who cared enough and was mature enough to push her away from him. Her trauma is not only that she "died", but also the blame for the gang war that broke out because of her actions, the fact that she was pushed out of her normal life for two years, the physical torture (some of which is heavily implied to be sexual) that caused her "death". Her trauma is not just that no one in Batfam thought she was capable of being a hero, but that no one thought she was capable of anything, including her teachers and the kids at her school, who all judged her by her father. Every adult who might have seen something in her turned out to be either a complete bastard (like her gymnastics coach) or didn't have the time, ability, or desire to become her mentor (like Dinah, Selina, or Helena). Her trauma is so much more than "her dad was a villain" her trauma is that she is a failure of the system, that no one ever cared enough, that her dad affected every part of her life even if he had nothing to do with it.
