Charlotte Cassadine’s bad attitude and fits of anger started escalating when her family situation imploded. She formed a close relationship with her stepmother, Nina Reeves (Cynthia Watros), after accepting the fact that Claudette had died — even though she really hadn’t. To make the child even more confused, Lulu Falconeri revealed to Charlotte that she was her biological mother, which was immensely upsetting to the little girl. Valentin Cassadine eventually won sole custody of his daughter but lost that privilege when he went to jail after running away with Charlotte. She moved in with Lulu and her husband, Dante Falconeri (Dominic Zamprogna), until Valentin was released and a shared custody agreement was reached.
Nina and Valentin then broke up, and the constant turmoil was too much for Charlotte; she started bullying her cousin Aiden Spencer (Enzo De Angelis) at school and taking her anger out on adults, developing a serious attitude problem, which she blamed on Nina. Her anger subsided a little when Nina and Valentin got back together and got engaged; Charlotte was happy for the time being to have Nina back in her life, but that didn’t stop her trouble-making ways for long.
