Plot
Gerry O'Toole, a supposed friend of Darrin's family, visits, but turns out to be a wood nymph, a mortal archenemy of witches. Samantha travels back to the fifteenth century to lift a five-hundred-year-old curse placed upon Darrin the Bold and his descendants after he murdered Rufus the Red.

Bloopers and Continuity Errors

 * Plot hole: The curse was put on Darrin the Bold and all of his descendants. However, no mention is made in this episode or the series whether the curse ever affected Darrin's father or any of his other ancestors.
