Mafia 21.

Revan, do the Mafia only have one ND? That would be silly, because why would they need a block and protection when they can just kill? At least I don't remember that being the case in our Mafia games. Usually, either all the killers or two NDs are assigned for the night.
The town couple might also have something like that, several NDs between them, like in the 6th game.
