Buffy the Vampire Slayer: Triangle

Giles travels to London for a watchers' meeting to discuss Glory and leaves Anya in charge of the Magic Box. But when Willow uses the store's supplies to cast a spell that will create sunshine to help Buffy slay vampires, Anya argues with her and the distracted Willow releases a troll imprisoned in a parallel world. Olaf the troll destroys the store and goes to the Bronze to drink beer and eat babies. Willow and Anya chase after him, but are soon caught. Xander tries to rescue them, but the only way to save them is to choose between the life of his girlfriend or that of his best friend.
