Synopsis by Brian J. Dillard
The big day has finally arrived: Xander (Nicholas Brendon) and Anya (Emma Caulfield) are getting married. The obstacles on their path to wedded bliss include atrocious bridesmaid's dresses, a stubborn cumberbund, and bitter sniping from the alcoholic Harris clan about the "circus freaks" (aka demons) who make up Anya's half of the wedding party. During the preparations, Buffy (Sarah Michelle Gellar) has a wistful encounter with Spike (James Marsters), whose cheap floozie of a wedding date causes pangs of jealousy even as the Slayer resolves to keep their relationship in the past tense. As for Anya, her dreams of wedded bliss soon also recede into memory when Xander disappears from the chapel. It seems the prospective groom has received a visit from his time-traveling, elderly self, who shows Xander a vision of the future in which his marriage ends in bitterness and murder. Later, when old-man Xander turns out to be a disguised enemy of Anya seeking revenge against the former vengeance demon, Xander still can't overcome his conviction that he isn't ready to get married. The guests riot, the absentee groom checks into a hotel, and the jilted bride turns to D'Hoffryn (Andy Umberger), her former demon master, for comfort. Originally broadcast March 5, 2002, on UPN, "Hell's Bells" marked episode 116 of the cult-favorite series.
