"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:
...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."
--Spike to Buffy (“Touched”, Buffy the Vampire Slayer, Season 7)
