Sybil had created all these personalities to cope with the different horrible moments that she experienced because she was so young and was unable to cope with it alone. She needed a support system, so they become a wall that prevented her from facing what her mother had done to her. As she grew older, she depended on these personalities more and more to get her through the day; helping her face things that she could not face otherwise alone. .

However, this was somewhat derailed when after one Christmas dinner with her neighbor Richard, her suicidal persona named Marsha shows up and he finds out about the personalities. Although they loved each other he was unable to handle it and moves way. This causes Sybil to make a shocking confession to Dr. Wilbur, stating that the personalities were not real and apologized for deceiving her. In order to help her, she travels to Sybil's hometown of Wisconsin to find evidence that proves that what had happened to her was in fact the truth; when doing this she convinces Sybil to face her fears. .
Although petrified of what she called "the green room; " the place where she got sexually assaulted which was her most frightening memory, she did recall what had happened and screamed overwhelming hatred towards her mother for an awful, wicked, and unnecessary act of violent that had been done to her.
