They arrive at the mansion and meet the butler, John and Corinne's cold mother Olivia, a religious fanatic. Olivia takes the group into her home, and escort them to a large bedroom of the mansion, with bars on the windows - blocking out fresh air and sunshine. It is on their first day there that the grandmother reveals the shocking truth: Corinne and her husband were really half- uncle and niece, making their love incestuous and their children the product of incest. She also tells them that the Grandfather will never know of their existence in order to spare him from the 'final agony and shame'.
