Angel, Season 1

Angel:
Hi. Can I come in?

Kate:
Oh, that's right. You have to be invited in, don't you?

Angel:
[pause] You've been doing your homework.

Kate:
Want to quiz me? I'm just full of fun facts. For instance, I learned that your friend has been in L.A. before, did you know that? Yeah, at least twice. Once in 1929 and again in 1963. Oh, and there was something in Boston in 1908, I think he was there, too.

Angel:
So you believe me.

Kate:
Yes, I believe you...

Angel:
Good, because he's planning something el...

Kate:
...Angelus. Isn't that what he called you? Angelus? I looked it up, it's all right there. The demon with the face of an angel. A particularly brutal bastard, by all accounts. Oh, and no, you can't come in.

Angel:
I can't make up for the past, Kate, I know that...

Kate:
No, you can't. In fact, all of this? What's happening now? Is because of you. You made him, didn't you?

Angel:
Then let me help end it. Please.

Kate:
'Please.' Now there's a word I imagine you heard quite a lot in your time. 'Please.' 'No.' 'Don't.' Thanks for the offer, but I don't need your help. I know what to do. Drive a stake right through the son of a bitch's heart. And when that happens, I suggest you don't be there, because the next time we meet, I'll do the same to you.
