 It turns out that Halloween is the one night of the year when vampires actually lay low, so everybody is getting their costumes from the new store in town, Ethan s Costume Shop. Buffy wears a noble woman s dress from the time when Angel was human, Xander dresses up like a soldier, and Willow chickens out on dressing like a hooker and goes as a ghost. But Ethan Rayne, the shop owner, has invoked the Roman god Janus so everybody becomes their costume. That means all the kids in the neighborhood are now monsters and Buffy thinks she is an 18th-century maiden who faints at the sight of demons and vampires.
