Bennett Halverson was the chief programmer for the Washington, D.C. Dollhouse and an intellectual genius who was considered one of Rossum's rising stars. Bennett was also well known for her accomplishments achieving technological feats that no one else thought possible were or able to do themselves, such as repairing damaged imprint wedges without data loss or corruption. Her mannerisms and speech suggest she is a nihilist and also slightly deranged. She can also be manipulative, playing on Topher's attraction to her. Unlike Topher's, Bennett's office is sparse and neatly organized.
