In every generation, there is a Chosen One. A slayer destined to protect the human race. She alone must fight the demons of hell. She alone must risk her life to stop the spread of evil. Buffy is the Chosen One.
A night at the fair becomes a night of terror for Buffy and her friends when their personalities start matching the amusements in the park in "Carnival of Souls."
In "One Thing or Your Mother," Buffy must face a fear worse than her typical demon: children.
In "Blooded, " Willow accidentally turns her body into a vessel for the spirit of an ancient warrior--and he's out for revenge.
