Post-it notes everywhere

[fenchurche.livejournal.com]

I recently remembered a scene from a fic and it's been driving me crazy trying to remember what story it was from. In it, Spike is aware of something the Scoobies aren't... there's a spell of some sort keeping them from noticing it (it might even be that Ben is Glory, but I don't recall for sure). At some point, the spell finally breaks and they realize that Spike had been trying everything he could think of to get through to them, including pasting post-it notes all over the place (covering the walls with them, that sort of thing).

Ring any bells with anyone?
