Spike: You listen to me. [Kneels in front of her.] I've been alive a bit longer than you, and dead a lot longer than that. I've seen things you couldn't imagine, and done things I prefer you didn't. I don't exactly have a reputation for being a thinker. I follow my blood, which doesn't exactly rush in the direction of my brain. So I make a lot of mistakes, a lot of wrong bloody calls. A hundred plus years, and there's only one thing I've ever been sure of: you. [Buffy looks away; he reaches toward her face.] Hey, look at me. I'm not asking you for anything. When I say, "I love you, " it's not because I want you or because I can't have you. It has nothing to do with me. I love what you are, what you do, how you try. I've seen your kindness and your strength. I've seen the best and the worst of you. And I understand with perfect clarity exactly what you are. You're a hell of a woman. You're the one, Buffy.
Buffy: [Quietly.] I don't wanna be the one.
[After saving Giles from a vampire.]
Spike: Awww, poor Watcher. Did your life flash before your eyes? Cup of tea, cup of tea, almost-got-shagged, cup of tea?
School Hard - S2-E3
Vampire: And when I kill her, it will be the greatest event since the crucifixion. And I should know, I was there.
Spike: You were there?! If every vampire who said he was actually at the crucifixion really was there, it would've been like Woodstock!
Xander: They'll never know how tough it is, Dawnie. To be the one who isn't chosen. To live so near to the spotlight and never step in it. But I know. I see more than anybody realizes because nobody's watching me. I saw you last night. I see you working here today. You're not special. You're extraordinary.
Angel: I did a lot of unconscionable things when I became a vampire. Drusilla was the worst. She was...an obsession of mine. She was pure, and sweet and chaste.
Buffy: You made her a vampire.
Angel: First I made her insane. Killed everyone she loved, visited every mental torture on her I could devise. She eventually fled to a convent, and on the day she took her holy orders, I turned her into a demon.
Willow: That's me as a vampire? I'm so evil and...skanky. And I think I'm kind of gay.
Giles: Let me get this straight: you think I'm evil if I take a group of teenage girls on a camping trip and I DON'T touch them?
Buffy: Cordelia, your mouth is open, sound is coming from it. This is never good.
Hank Summers: At least when she was burning stuff down, I knew what to say.
School Hard - S2-E3
Spike: You know what I find works with Slayers? Killing them.
Xander: I think I'm having a thought. Oh yeah, that's a thought. [Gasp.] Now I'm having a plan!
Buffy: This is Andrew, he's our hostage.
Andrew: I prefer guestage.
Band Candy - S3-E6
Willow: Kiss rocks? Why would anyone want to kiss...oh, wait. I get it.
Dirty Girls - S7-E18
Xander: I've been through more battles with Buffy than you all can ever imagine. She's stopped everything that's ever come up against her. She's laid down her life - literally - to protect the people around her. This girl has died *two* times, and she's still standing. You're scared? That's smart. You've got questions? You should. But you doubt her motives, you think Buffy's all about the kill, then you take the little bus to battle. I've seen her heart - and this time not literally - and I'm telling you right now, she cares more about your lives than you will ever know. You gotta trust her. She's earned it.
Faith: Damn. I never knew you were that cool.
Buffy: Well, you always were a little slow.
Chosen answer: Angel is saying that he is still jealous and Buffy recognizes that this is his way of saying he wishes that they could be together. That is why they both smile.
