Buffy the Vampire Slayer, Season 4

[Spike, having tricked Willow into inviting him into her dorm room, prepares to attack her.]

Spike:
I'll give you a choice. Now I'm going to kill you - no choice in that. But I can let you stay dead... or bring you back, to be like me.

Willow [frightened]:
I'll scream!

Spike:
Bonus. [moves toward Willow's neck]

...

[A short time later, Spike sits on Willow's bed, confused and disconsolate. Willow still cowers from him.]

Spike:
I don't understand. This sort of thing's never happened to me b-before.

Willow:
Maybe you were nervous.

Spike:
I felt all right when I started. Let's try again. [he leaps on her and draws back in pain] Ow! Oh! {he tries again] Ow! Damn it!

Willow:
Maybe you're trying too hard. Doesn't this happen to every vampire?

Spike:
Not to me it doesn't.

Willow:
It's me, isn't it?

Spike:
What are you talking about?

Willow:
Well, you came looking for Buffy, then settled. You didn't wanna bite me. I just happened to be around.

Spike:
Piffle.

Willow:
I know I'm not the kind of girl vamps like to sink their teeth into. It's always like, "Oooh, you're like a sister to me," or, "Oh, you're such a good friend."

Spike:
Don't be ridiculous. I'd bite you in a heartbeat.

Willow:
Really?

Spike:
Thought about it.

Willow:
When?

Spike:
Remember last year, you had on that, uh, fuzzy pink number with the lilac underneath?

Willow:
I never would've guessed. You played the blood-lust kinda cool.

Spike:
Mmm. I hate being obvious. All fangy and "rrr!" Takes the mystery out.

Willow:
But if you could...

Spike:
If I could, yeah.

[beat]

Willow:
You know, this doesn't make you any less terrifying.

Spike:
Don't patronize me. [desperate and embarrassed]: I'm only 126!

Willow:
You're being too hard on yourself. Why don't we wait a half an hour and try again? Or...

[Willow grabs a lamp, smashes it over Spike's head and tries to flee the room.]
