Haddie Hart is a former Umbrella HQ and NEST researcher. After proving her worth and trustworthiness to the Umbrella Corporation, she was one of many chosen to be transferred to the NEST, where she would 'keep an eye' on the facility. Haddie became Dr. Finley Bondevik's research assistant in early 1998, as his close relationship with Dr. William Birkin would make it easier to monitor his behavior.
