Giles and Buffy in “Tabula Rasa”

Giles

I have to.

Buffy

Uh-huh.

Giles

You have to be strong. I-I'm trying to--

Buffy

Trying to-to what? Desert me? Abandon me? Leave me all alone when I really need somebody?

Giles

I don't want to leave.

Buffy

So don't. Please don't. I can't do this without you.

Giles

You can. That's why I'm going. As long as I stay, you will always turn to me if something comes up that you feel you can't handle, and I'll step in, because-- (sighs) because I can't bear to see you suffer.

Buffy

Me too. Hate suffering. Had about as much of it as I can take.

Giles

Believe me, I'm loathe to 'cause you more, but this-- I've taught you all I can about being the Slayer, and your mother taught you what you needed to know about life. You... You're not gonna trust that until you're forced to stand alone.

Buffy

But why now? Now that you know where I've been, what I'm going through?

Giles

Now more than ever. The temptation to give up is going to be overwhelming, and I can't let--

Buffy

So I won't. No giving up. You can be here, and I can still be strong.

Giles

Buffy, I've thought this over and over. I believe it's the right thing to do.

Buffy

You're wrong.
