Buffy the Vampire Slayer, Season 7

Holden:
Oh, I have so much to learn. Come on, isn't this insane? I mean, I was afraid to talk to you in high school, and now we're, like, mortal enemies. Hey, wouldn't it be cool if we became nemeses?

Buffy:
Is that how you say the word?

Holden:
We're gonna have to fight to the death, aren't we?

Buffy:
It's the time-honored custom.

Holden:
Wow, reality just shows up sometimes, doesn't it? But, you know, I've got the bloodlust pumping, and I kinda get it. I'm looking for a fight. And, oh, it's nothing personal.

Buffy:
Oh, no, I mean, you've been great.

...

Holden:
Hey, I don't mean to be Count Buttinsky here, but you just don't seem as thrilled. Is it because we're gonna fight?

Buffy:
It's because I'm gonna win.

Holden:
Hello! Two years of Tae Kwon Do and vampire strength. I think somebody's counting their chickens.

Buffy:
You're not leaving this graveyard. Can't let you.

...

Buffy:
If you knew what I've done, what I've let myself become. My best friends don't even know. You'd laugh if you heard some of the things I've done to them.

Holden:
Buffy, I'm here to kill you, not to judge you.
