I had a thought this morning about the episode Band Candy for a Giles/Ethan story. Ethan takes the Band Candy gig, knowing the chocolate will revert adults to teenagers, in the hopes of bedding Giles while his inhibitions are lowered (either for the first or last time).
Anyone know if this has been written? If so, can you point me towards it? Or, if not, anyone want to write it?
