Entering the secret playroom, Hallie (Kathy Cody) becomes possessed by a ghost from the past; in this state, she is met by the spirit of Daphne Harridge (Kate Jackson), who'd been governess to Tad Collins and Carrie Stokes some 130 years before. As Julia (Grayson Hall) tries to learn more about Daphne's contemporary Gerard Stiles, Quentin (David Selby) experiences a bizarre dream.
