Have been discussing 'what did Spike ask for - the chip out or his soul back?' in the AOQ 'Grave' thread, and the nay-sayers keep going on about the stupid dialogue and saying that there's no hint that Spike has asked for a soul (the fact that the thing was written to be as fuzzy as possible is lost on them). But... (from 'Villains'):

The Lurking demon says: "...and you have the audacity to crawl in here and demand restoration?"

The gypies re-souling spell is called 'The Ritual of Restoration.'

Now that is just... neat. :)
