Bring on the night: "I'm standing on the mouth of hell and it's about to swallow me. But you know what? It'll choke on me." and "There's only one thing more powerful than evil on this Earth, and that's us. Because we just became an army."
Potential: Xander's speech to Dawn. "Seven years, Dawn. Working with the slayer. Seeing my friends get more and more powerful. A witch. A demon. Hell, I could fit Oz in my shaving kit, but come a full moon, he had a wolfy mojo not to be messed with. Powerful. All of them. And I'm the guy who fixes the windows....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."
Touched: Spike: "You listen to me. 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'd 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. 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 are a hell of a woman. You're the one Buffy.
And then of course: CHOSEN: "I want you to get out of my face" and "I love you"
