As I told Tazz via VM, I find it improbable that Casadriel is Mafia. If he was, it would make most sense for me to be the next target. It would appear that Mafia is all inactive or dead, and that Homura is essentially RNGing their choices. Arch Enemy makes no strategic sense as a choice.

Therefore, I cast my vote for MuddyMudkip. As discussed previously.
