Well, that was excellent, and incredibly surprising! I have a huge kink for Spuffy baby fic, and I really enjoyed the whole dynamic (the revelatory moment between Buffy and Spike about him having a soul and being the father was fantastic), until the end, which absolutely ripped my heart out! You really managed to do something new and interesting with this story, with all kinds of great subversion and wit, I'm definitely going to be chewing on it for a while.
