Right, rereading what you wrote, you said it represented Gundling specifically. I was thinking of it as a fool symbol. Good point about FW, though, and his quest to continue humiliating Gundling after death. It could go either way. Poor Gundling. AU where he offs FW!

Oh, you know that Agatha Christie book where the answer is *everyone* did it? We could come up with one like that for FW! (ETA: Deliberately not naming it or giving details in case someone hasn't read it.)
