Buffy the Vampire Slayer, Season 6

Xander:
Hey, black-eyed girl… Whatcha doin'?

Dark Willow:
Get out of here.

Xander:
Oh no… You're not the only one with powers, you know. You may be a hopped up uber-witch, but this carpenter can dry-wall you into the next century.

Willow:
I'm not joking, Xander. Get out of my way. Now. You can't stop this.

Xander:
Yeah, I get that. It's just where else am I gonna go? You've been my best friend my whole life. World gonna end… where else would I want to be?

Willow:
Is this the master plan? You're gonna stop me by telling me ya love me?

Xander:
Well, I was going to walk you off a cliff and hand you an anvil, but, eh, it seemed kinda cartoony.

Willow:
Still making jokes.

Xander:
I'm not joking. I know you're in pain. I can't imagine the pain you're in. And I know you're about to do something apocalyptically evil and stupid and hey, still wanna hang. You're Willow.

Willow:
Don't call me that!

Xander:
First day of kindergarten. You cried because you broke the yellow crayon, and you were too afraid to tell anyone. You've come pretty far, ending the world, not a terrific notion. But the thing is? Yeah. I love you. I loved crayon-breaky Willow and I love ... scary veiny Willow. So if I'm going out, it's here. If you wanna kill the world? Well, then start with me. I've earned that.

Willow:
You think I won't?

Xander:
It doesn't matter. I'll still love you.

Willow:
Shut up!

Xander:
I love you. I… lov-

Willow:
Shut up!

Xander:
I love you, Willow.

Willow:
Stop…

Xander:
I love you.

Willow:
Stop!

Xander:
I love you.
