Where we let the eyebrows do the talking

This may be inappropriate &, if so, I apologize in advance. But it seems like you might want to ask the mods of lornes_diner if you can cross-post this challenge there, &/or tell folks here at slashing_lorne about the cool 'verse there. After all: vampires, winged fey creatures, the suggestion of other supernatural creatures, magical mirrors & objects, mysterious time/space travel with lurking hungry predators, a sentient (& bossy!) diner: what more could you want in a Hallowe'en fic or setting? Who knows, maybe the mods of lornes_diner would like to run a simultaneous challenge....
