Buffy the Vampire Slayer, Season 7

Buffy:
So, did you bring back any Potentials?

Giles:
Um, rea- no. Actually, m-my, uh, my trip is about something else. It's-it's, um, regarding Spike.

Buffy:
Spike. What about him?

Giles:
I told you my concerns when you recklessly chose to remove the chip from his head.

Robin:
Wait, sorry - chip?

Giles:
Well, uh, it's a... long story.

Buffy:
The military put a chip in Spike's head so he couldn't hurt anyone.

Giles:
And that would be the abridged version.

Buffy:
But he wouldn't hurt anyone anymore because he has a soul now.

Giles:
Unless the First triggers him again.

Robin:
Triggers the chip?

Buffy:
No, the trigger's a post-hypnotic thing. The First put it in his head. It was... made him… He was killing again.

Robin:
So, he has a trigger, a soul, and a chip?

Giles:
Not anymore!

Buffy:
It was killing him, Giles!

Robin:
The trigger?

Buffy:
No, the chip. The trigger's not active anymore.

Robin:
Because the military gave him a soul?

[Giles tries to think an adequate response. Buffy glares at Robin, who gestures in surrender.]

Robin:
Uh... sorry.
