Doll rarely spoke to anyone, talking occasionally with her friend Lizzy and giving enigmatic non-answers to questions anyone might have. As well as being quiet, Doll lacked any interest in expressing herself to others under the assumption that no one understands how to help her. she watched her parents die at the hands of V. After they died, she would keep their corpses in her home and pretend that they were alive, covering them under sheets. She is also an absolute solver drone.
