Enjoyed this chapter but you sure know how to string us along.  If Spike remembered everything, please don't let him mull for a while.  So not in character for the impulsive one. 

“Every—last—one,” Spike purred into the shell of her ear.   LOL  I'm afraid Buffy is going to have to kick his ass really hard.  Great chapter.  :)

I swear did none of their parents teach any of them manners? Even Giles! So what Spike is a vamp, big deal. If you start a conversation off rude and nasty that is what you are going to get in return. (It was a big problem I had with their interactions on the show with Spike too. They were mean because they could and once he started helping they never got any better.)

Would it have killed her to go by his place sooner to check on him? Hell Giles could have done it and called it research on Toth! He gets captured, experimented on, escapes, get tied to a chair, shot by arrows, chained to a tub. Then gets split in half. They know he is unable to get his food the normal way and he is defenseless against humans. So how exactly is he supposed to support himself? At the very least someone could have checked up on him.
