The Worms that Walk
Sara is the project manager for the Paradise Theater renovation project. The investigators initially met her when they visited the Paradise Theater, and claimed to be members of a historical theater society.
Her staff visited Mary Green at the local hospital, and allowed the investigators to tag along.
Later that evening, the investigators ran into her again when caught by police attempting to break into the Paradise Theater after hours. Though they convinced the police that they were private security contractors for the theater, Sara knew otherwise. Sara, whether confused from the events of the day or the late hour, was convinced by the private investigators that they were just innocent bystanders caught by police while being good Samaritans, and that they only claimed to be security to get out of an awkward situation.
Sara currently seems confused and distrusting of the investigators, but has begrudgingly allowed the group to return the next day.
