Actually, Dru's 'fessed up that they show up early, because she likes to have time in the castle without lots of other vampires, just so she can hang out with someone else who understands visions, while Spike wanders around and then acts righteously indignant when Herbert decides to seduce him. Not that it happens often. Definitely not every time they visit. Especially not with Herbert jumping him from behind. Never ever happens. Not at all.

And it has Spike quoting either Keats or Milton, post coitus. I haven't decided which yet :D (What I love about joss is that from Spike's first episode, he was actually quoting Shakespeare and no one picked up on it :D)
