Synopsis by Brian J. Dillard
Giles (Anthony Stewart Head) arrives at the Magic Box and mystically shackles the grief-mad Willow (Alyson Hannigan), then hears from Buffy (Sarah Michelle Gellar) about everything that's gone down since his departure (see "Tabula Rasa"). Their joyful reunion is interrupted, though, when Willow mystically compels Anya (Emma Caulfield) to free her. Luckily, Giles has come to end the Wiccan's rampage, and he's armed with the magicks of an entire coven. They battle epically, but soon Willow drains Giles of his powers and leaves him near-dead. Elsewhere, Xander (Nicholas Brendon) and Dawn (Michelle Trachtenberg) are on the run with surviving super-nerds Jonathan (Danny Strong) and Andrew (Tom Lenk). Willow dispatches the magical equivalent of a guided missile to kill the villains and their reluctant protectors. Buffy manages to save her friends, but in the confusion, Jonathan and Andrew escape; Buffy and Dawn end up in a cavern full of zombies. As for Willow, the influx of Giles' power puts her magically in touch with the pain and suffering of the entire planet; she resolves to burn the Earth to a cinder. Anya warns Xander of the impending apocalypse and he rushes to the rocky bluff where Willow is raising the malign temple of an ancient doomsday cult. Despite Willow's vicious attacks, Xander showers her with love and acceptance, which eventually drains her of black magic and restores her humanity. Meanwhile, after battling side by side with her sister, Buffy finally realizes that she's glad to be alive again. And in a dark cave somewhere in Africa, Spike (James Marsters) completes his quest to be returned to his former self. But his demon taskmaster doesn't remove the chip in Spike's head -- he returns the vampire's soul. Originally broadcast May 21, 2002, on UPN, "Grave" marked episode 122 of the cult-favorite series.
