1. I think there's a sequel to Bonfire Night by amejisuto and kitty_poker1; I swear to god I've read this somewhere, but I can't find it! I remember teh bois getting dressed in tuxes and going to a fancy dinner with Buffy and the Immortal, and Buffy was acting sort of like an abused wife with him. I'm pretty sure it's a WIP, too.
2. I don't remember the title or author, but it's a Christmas story where Xander carves a wooden ornament for Spike for each of the twelve days of Christmas.
