Dr. Bethanie Ravencroft is a psychotherapist in Gotham City. She conducted the mental experiments that created Magpie. Unknowingly, Ravencroft hired Magpie under the guise of "Cassie" as a receptionist. Magpie studied the doctor's movements and finally abducted her with the intent to force her to reverse the experiments and give her back her memories.
Thanks to Batman, Ravencroft was freed. She later asked Bruce Wayne out on a date, as they had met when Bruce had gone to see her as a patient in order to search her office for clues. While on their date, Bruce left for a moment to take a phone call. While he was gone Ravencroft sent a mysterious text message to an unknown recipient. The message read: "Wayne's hooked". Awaiting instructions." In the episode Family, she lured Wayne into a trap by the League of Assassins. Later in the episode, her soul was drained by Lady Shiva and imprisoned within the Soultaker Sword, leaving her alive, but a husk.
