I'm partial to the entire Wesley/'Lilah' dialogue of Salvage.
LILAH
Why so glum? It is kinda what you wanted, isn't it? I mean, deep down. Me out of the picture—utterly, finally. You can't get outer than this. It makes your life simpler, doesn't it? Cleaner?
WESLEY
I didn't want this.
LILAH
Come on, what are you worried about, Wesley? (sits up, on the far edge of the table, facing away from him) You hated yourself for being with me. Or maybe you just hated yourself for loving being with me. (laughs) Hey, semantics. (stands, walks to Wesley) In any case, we both knew, sooner or later, it would come to a messy end. For one of us, anyway. (pulls him to face her; she touches his face and arms) So ease up on that furrowed brow. You're free now. No longer encumbered with the secret shame of our relationship.
WESLEY
It wasn't a relationship.
LILAH
There's a signed dollar bill in your wallet I think proves different. You knew how I felt.
WESLEY
You don't feel.
LILAH
The only true thing I ever—
WESLEY
(faces away from Lilah to look back at the table) You didn't love me. (stares at her corpse that's still on the table) You couldn't.
LILAH
(standing beside him) We'll never know now, will we?
Cut to
LILAH
I know what it is. The reason you're having such a hard time with this. Why you're taking so long to—you know... (makes a creaking noise as she gestures across her throat with her hand) The awful truth: you couldn't save me. And this is the exclamation point.
WESLEY
Saved you from the Beast, for all the good it did.
LILAH
(smiles) Wesley, you know that's not what I'm talking about. You couldn't save me from me.
WESLEY
Is that what you thought?
LILAH
Me? (laughs) Lover, I'm not even here. I'm just a figment in your devilishly handsome head. So, clearly, it's what you thought. For all your supposed darkness, edge of the razor mystique, (whispers in his ear) there was always a small part of you that thought you could pull me back from the brink of my evil, evil ways. Help me find redemption.
WESLEY
Redemption?
LILAH
(stands behind him with her hands on his shoulders) Angel's influence, I suppose. The whole not giving up on someone, no matter how far he—or she—has fallen. Oh, well. Too late for me. (Wes stands) Let's just get it over with. That body's not gonna dismember itself, you know.
WESLEY
(lifts the battle-axe) I'm sorry, Lilah.
LILAH
Oh, Wes, we don't have that word in our vocabulary. Not people like you and—
Wesley swings the axe. When he pulls it back, it's got blood on its edge. He cries.
