BtVS Season 2:

"We like to talk big. Vampires do. 'I'm going to destroy the world.' That's just tough guy talk. Strutting around with your friends over a pint of blood. The truth is, I like this world. You've got... dog racing, Manchester United. And you've got people. Billions of people walking around like Happy Meals with legs. It's all right here. But then someone comes along with a vision. With a real... passion for destruction. Angel could pull it off. Goodbye, Picadilly. Farewell, Leicester Bloody Square. You know what I'm saying?"

BtVS Season 3:

"I'm really glad I came here, you know? I've been all wrongheaded about this. Weeping, crawling, blaming everybody else. I want Dru back, I've just gotta be the man I was, (stands proud) the man she loved. I'm gonna do what I shoulda done in the first place: I'll find her, wherever she is, tie her up, torture her until she likes me again. (goes to leave) Love's a funny thing."

BtVS Season 4:

(There's a knock at the door. Buffy goes to answer it and Spike is standing there, cowering below a smoking blanket.)

SPIKE: Help me.

(Buffy shoves him back and he goes tumbling.)

SPIKE: Ohh! What part of "help me" do you not understand?

BUFFY: The part where I help you.

SPIKE: Come on, I'm parboiling out here.

BUFFY: Want me to help make it quicker?

SPIKE: Invite me in.

GILES: No. It's fairly unlikely.

SPIKE: Oh, damn it! look, I'm safe. I can't bite anyone. Willow, tell' em what I did.

WILLOW: You said you were gonna kill me, then Buffy.

SPIKE: Yes, bad, but let's skip that part and get to the part where I couldn't bite you.

WILLOW: It's true. He had trouble performing.

SPIKE: Yeah, well, it looks like they've done me for good. Um...

BUFFY: What are you saying?

SPIKE: I'm saying that Spike had a little trip to the vet and now he doesn't chase the other puppies anymore. I can't bite anything. I can't even hit people.

BUFFY: So you haven't murdered anybody lately? Let's be best pals.

XANDER: Spike?

GILES: What are you doing here?

SPIKE: Me? Hey, I'm not the one out of place here.

XANDER: For your information, smarty, we've got a rogue Slayer on our hands. Real psycho-killer too.

SPIKE: Sounds serious.

GILES: It is. What do you know?

SPIKE: What do you need?

XANDER: Her. Dark hair. Yay (Indicates) tall, name of Faith, criminally insane.

GILES: Have you seen her?

SPIKE: Is this bird after you?

XANDER: In a bad way, yeah.

SPIKE: Tell you what I'll do then. I'll head out, find this girl, tell her exactly where you are and then watch as she kills you. Can't any one of your damn little Scooby club at least try to remember that I hate you all? Just because I can't do the damage myself doesn't stop me from aiming a loose cannon your way. And here I thought the evening be dull.

XANDER: Go ahead. You wouldn't even recognise her.

SPIKE: Dark hair, this tall (Indicates), name of Faith, criminally insane. Like this girl already.

(he walks off)

XANDER: We're dumb.
