Synopsis by Brian J. Dillard
Buffy (Sarah Michelle Gellar) denies being attracted to Spike (James Marsters), both to herself and to the bad-boy vamp. But when he catches her holding on to a memento from their tryst, she grows furious and chops off a great deal of her hair. The Slayer soon gets an even more radical makeover when she's hit by an invisibility ray -- nerdy villains Warren (Adam Busch), Andrew (Tom Lenk), and Jonathan (Danny Strong) are at it again with the super-weapons. This time, the Slayer's happy for the change. Merrily pulling pranks on people around town -- including the social service worker who's been critiquing her parenting skills -- Buffy soon makes her way to Spike's crypt for some X-rated fun. Meanwhile, Xander (Nicholas Brendon) offends Willow (Alyson Hannigan) by accusing her of turning Buffy invisible. Miffed, the recovering magic addict sets about finding the real culprit -- without supernatural help. Thanks to Willow's exhaustive detective work, Anya (Emma Caulfield) discovers that anything hit by the ray gun soon turns to invisible mush. Looking to warn Buffy of the impending danger, Xander interrupts Spike and the Slayer's lovemaking. With Buffy invisible, though, Spike is able to pretend he's merely exercising. As Buffy continues her escapade, unaware that she's about to turn to pudding, the super-nerd troika kidnaps Willow. During the battle that follows, Buffy regains her visibility and finally comes face to face with the dorks who've been persecuting her. The geeks escape, but her near-jellification at their hands finally convinces Buffy to be grateful that she's back from the dead. Originally broadcast January 8, 2002, on UPN, "Gone" marked episode 111 of the cult-favorite series.
