It's Friday the 13th. Cats can scare the living daylights of people so Salem is having a lot of fun. Sabrina finds out that it's also a day when witches can tell mortals their secret because they will forget at the end of the day. Despite warnings from her aunt, Sabrina tells Valerie who tells Harvey. Libby also overhears that Sabrina is a witch and plans to expose her. Valerie gets Sabrina to do lots of spells in school. In the meantime, Zelda tries to find a cure for Hilda's bat breath.
