Jenny Reynolds is a minor character from American Horror Story: Asylum Nikki Hahnn.
Jenny was a young girl whose mother feared that her daughter murdered her playmate after discovering the girl's hair in her coat. After Miss Reynolds left her, a possessed Sister Mary Eunice briefly "babysat" her, revealing Jenny was far smarter than other girls her age and she should eliminate anyone who attempted to mess with her. It was also revealed Jenny did kill her friend. After dubious advice from Sister Mary Eunice, she is picked up by her mother. Later in the episode, Jenny murders her entire family and describes to the police a fictional description similar to the one she gave to her first known murder, while at the crime scene, having already grabbed hair from each of her family members as twisted trophies. It is unknown what becomes of Jenny afterwards.
