Doll rarely spoke to anyone, talking occasionally with her best friend, Lizzy, and giving enigmatic non-answers to questions anyone might have. In addition to being quiet, Doll lacked any interest in expressing herself to others under the assumption that no one understands how to help her. Beneath her facade of an introvert who prefers to keep to herself are deep psychological problems. Doll has shown herself to be determined and deadly, but she has also shown keen perception.
