Returning to the house to learn about the ''Electrickery" Catweazle hears the kettle whistling in the kitchen and thinks it's a demon. He hides under the dining room table and draws a circle in chalk around him to protect himself whilst blowing on his magic thumb ring and chanting ''sator arepo tenet opera rotas''. Meanwhile Carrot's father comes into the house and can smell the same smell he first noticed in the barn the night before. Wondering how he can get Catweazle out of the room he deliberately knocks something over on the table and his father leaves to get something from the kitchen to clean it with. Trying to leave the house Catweazle is almost spotted by farmhand Sam and takes himself up to Carot's bedroom. After trying to clean the chalk stain off the carpet that Catweazle had made, Carrot follows his nose up to his bedroom where he finds Catweazle hiding in his wardrobe. Catweazle is in awe of how Carrot discovers him and then begs to be shown the ''magic of electrickery"... (thetvdb.com)
