Dani and Jimmy must each defend their branch of the family tree when a misunderstanding with local Mrs Crankett tells a legend of Bogmoor. Jimmy thinks that he should turn the castle into a witch world so he could earn lots of money, but Dani forces him not to. Otherwise everyone in the village will think that Dani is a witch. She reads a tale of a lady named Lavinia about her brother getting rid of her sister, is it because she was a witch, or was the witch not Lady Lavinia at all?
