Buffy was familiar with physical training, but it took her a few days to get her body back into the habit. By Sunday afternoon her body adjusted to where it didn't hurt as much. Buffy decided to confide ih Giles the truth about Caligo.
Buffy: He didn't kill those people at the plant. He died to stop Sarah's cult from releasing nerve gas on more innocent people. Everyone just assumed he was part of Sarah's plan, and I said nothing.
Giles: You were right. People wouldn't understand. It's easier to believe that a satanic preacher would try to murder innocent people, than that he and a young girl would save lives.
Buffy: I'm going to have to keep a lot of secrets, aren't I?
Giles: I'm afraid so. The slayer's identity must be kept secret, for your sake. You know what happenned when even one crazy woman knew the identities of even potential slayers. Imagine if you were a full slayer, and they knew it. The forces of darkness would come at you full strength, and that you could not survive. It is much easier to fight one vampire than a thousand.
Buffy: Does the word "Duh" mean anything to you?
Giles: The slayer's legend inspires hope in the innocent, fear in the wicked. Into each generation a slayer is born. One girl in all the world, a chosen one. Born with the strength and skill to hunt the vampires. To stop the spread of their evil and the swell of their numbers.
Buffy: And I'm suppossed to live up to all that hype?
Giles: If you become the slayer, yes Faith did not, but the legend continues to inspire many.
Buffy: And I can't talk about this with anyone.
Giles: For their sake as much as yours.
Buffy: Sounds lonely. And how long do slayers usually last?
Giles; It depends. Some, less than a year. Others live to a ripe old age of 100.
Buffy: It's the "less than a year" part that tends to stand out.
Giles: Which is why we should keep training like this. The more prepared you are if the calling comes, the better for all.
