Season 7, Episode 8 | Aired: 19 November 2002 | Written by: David Fury & Jane Espenson | Directed by: Alan J. Levi
Spike has been killing, under the First’s control, triggered by a specific song. The episode investigates whether he’s responsible — whether the soul means the actions are his — and arrives at a distinction the show is careful about: he’s being used, he’s not choosing. Buffy makes the decision not to kill him. She chains him in her basement instead, which is Season 7’s version of containment. A Watcher arrives from England at the episode’s end and is immediately killed by a Bringer.
What Happens
Spike is blacking out and bodies are turning up. He’s creating a vampire army under the First’s direction without knowing it. Buffy investigates. The trigger is a song — “Early One Morning” — used by the First to activate him, in the same way the Initiative’s chip worked as a trigger. Buffy confronts Spike; he’s staked mid-conversation by one of his own victims, turned. Giles is in England, speaking to Robson the Watcher. Robson is killed. The Bringer raises an axe.
Key Moments
Buffy’s decision not to kill Spike — based on the soul, based on what it cost him, based on her judgment that he’s being used rather than acting. It is a judgment that the season requires and the episode earns. And the Giles/Robson scene: the axe falling, the camera cutting away.
Monster / Villain
The First, operating through Spike. The Bringers, active in England. The vampire army, newly created.
Notable Quote
“I don’t understand. Am I… am I becoming a monster again?” — Spike. Buffy: “No. You didn’t know.”
Where It Fits
Sleeper is the episode that converts Spike from potential threat to confirmed ally — a decision Buffy makes and owns. His containment in her basement is the beginning of his Season 7 arc as a soldier rather than a danger.
