Buffy The Vampire Slayer S02E06

Halloween

Costume shop owner Ethan Rayne casts a spell that transforms kids into their costume personae. Angel and Cordelia try to help as Willow becomes a ghost, Xander a soldier, and Buffy a brainless, helpless 18th-century noblewoman. Spike joins the fun and tries to take advantage of the Slayer's predicament, but Giles breaks Ethan's spell at a critical moment.
