Angel, Season 1

Angel:
Buffy, this wasn't about you. This was about saving somebody's soul. That's what I do here and you're not a part of it. That was your idea, remember? We stay away from each other.

Buffy:
I came here because you were in danger.

Angel:
I'm in danger every day. You came here because of Faith. You were looking for vengeance.

Buffy:
I have a right to it!

Angel:
Not in my city!

[long pause]

Buffy:
I have someone in my life now, that I love. It's not what you and I had. It's very new. You know what makes it new? I trust him, I know him.

Angel:
That's great, it's nice you moved on; I can't. You found someone new; I'm not allowed to, remember? I see you again, it cuts me up inside, and the person I share that with is me. You don't know me anymore, so don't come down here with your great new life and expect me to do things your way. Go home.

Buffy:
See? Faith wins again.

Angel:
[huskily] Go.
