Buffy: The Initiative. Season 4 finally kicks into gear as the big arc plot of the season - the secret government unit hunting and experimenting on vampires/demons - starts to come into focus. The highlight of the episode, though, is the return of Spike - and what they do with him, in what has to be one of the smartest moves the show ever pulled. They loved Spike, but after having him as one of the major villains of season 2, they couldn't just keep bringing him back doing the same old thing, and they certainly couldn't him have as a regular (which he becomes from this episode on) if all he was going to was try to kill Buffy every week. The solution? Spike becomes a victim of the aforementioned government unit - and even though he eventually escapes, he does so to find that it is now impossible for him to kill, harm or even bite a living soul. It's a stroke of genuine genius - he's the same rat bastard we've come to secretly love, but as a threat, he has been utterly
neutered - and it's an impotence metaphor that provides unexpected comic gold in the scene where he first tries to attack Willow.
Willow: Doesn't it happen to every vampire?
Spike: Not to me it doesn't!
