Hee! Well, I'm a fan of the "imaginary story" from way back. Remember all those Silver Age DC comics, where the best stuff would happen, but then it was all "imaginary"? (Not canon, I guess.) Why not go that route with a bunch of the crappy stuff? It was Bizarro Buffy & Angel! It's a parallel dimension! It's a wacky Broadway nightmare! Like Spiderman!

Oh, so many ways to undo it! Stab it with its own weapon...as if it were a mystical bear.
