I'm looking for a fic in which Buffy either removes the amulet from Spike's neck or is somehow able to get him out before he burns in the final battle. Sunnydale is only half destroyed and the survivors resume residence at Revello Drive. Spike's soul is torn from him in the battle. Buffy and Spike go to LA to have Angel's team look into the amulet. Naturally, Angel is upset about Buffy and Spike's relationship. Eventually, it is discovered Spike's soul is trapped in the amulet.
One quirky thing I remember is Spike eats some very old Mac & Cheese. Buffy will not let him kiss her after that, so he takes some mouthwash and swallows it, not knowing how to "properly" use mouthwash.
