The stepmother is involved in a terrible crime that Lucius overhears (as a donkey) while under the ownership of the soldier. She lusts after her stepson who rejects her. After this rejection, she schemes to get revenge on him, but she accidentally poisons her biological son instead. As it turns out, however, the “poison” she received was only a sedative, so her biological son is still alive. Caught in a crime, the stepmother is exiled.
