I've always wondered about the killing of slayers. Spike drank from the first slayer he killed in China, but only for about .02 seconds, so there's no way he drained her. I suppose he and Dru had a bit of sex play with her (her blood, anyhow) in the interim between Dru finding him and them rejoining with Angel and Darla. But he never drank from Nicki Wood, just snapped her neck. Um, hello, tasty powerful slayer blood there?? Why just leave it?
Come to think of it, the Master didn't drink much from Buffy, either. Plot, right, I get it, but still-- you'd think he'd have drained every drop. And of course the whole Dru/Kendra death. Why would a vamp just waste blood like that?
This is really a production quandry, but why oh WHY must every metal weapon they ever touch make that twanging sheathy noise? Does anyone know what I'm talking about? Particularly when Willow picks up the scythe in (I forget which ep), she picks it up off the bed and it makes a noise like it was dramatically unsheathed?? It was on a comforter, for pete's sake??!!!
