Thanks for a really interesting sign-up. I would never have thought of any of this without it. It was clear that I had to write Mundungus, but I was also taken with all that info on Dedalus, and so the plot bunny was spawned!
I'm really glad that you enjoyed the end result. And, yeah, it's a shame about Dedalus' hat, but I expect that Dudlus will get him another just as soon as he can.
