Jenny had been created to act as a child for Mrs Meredith. She was one of the first Scions created. Her mother didn't like her very much, so Jenny spent most of her time wandering the town or visiting with others.
When Gwen Cooper, Rhys Williams and Anwen Williams came to Rawbone in 2011, Jenny was fascinated by Anwen. She knew she wasn't human and was interested in how humans grew. She spent as much time as she could with Gwen and Anwen, trying to learn more about them. When she was left alone with Anwen, Jenny decided to steal her, believing that with a child she would become more human. In fact, this attempt did work and Jenny was able to mature by force of will. When Sebastian took control of the Scions, Jenny fought back and returned them to normal. She then led them to confront and kill Sebastian. (PROSE: First Born)
