The Captain of the Guards carried her off, soothing her as she bawled "I want my mama". Cassandra, seeing her mother from the window, came outside, only to witness firsthand how her own mother cut the bridge across the moat in front of their cottage, cradling another child and showing it more affection than she ever showed her. On the night of the kidnapping, the guards chased her to the cottage, but she could not get to the cottage, and hid behind a rock. She lived her childhood in a quaint cottage by a waterfall, often being left alone and doing chores around the house while Gothel was out preparing to kidnap Princess Rapunzel. Rapunzel said that it made them sisters, which angered Cassandra. It was revealed that she is Mother Gothel's biological daughter. In Rapunzel's Return, Zhan Tiri showed her forgotten past. She also played an instrumental role in the return of Rapunzel's 70-feet of magic, golden hair. Her role generally required that she assist Rapunzel by any means necessary.
She is a skilled fighter who dreamt of joining the royal guard, though she formerly- and contently - served as Rapunzel's lady-in-waiting and closest confidante, alongside the princess' pet chameleon Pascal. Cassandra is the adopted daughter of Corona's Captain of the Guard.
