The last game I ran was openly all-vanilla, but the two Scum were a Godfather and an Investigator, anyway, mostly just for color (the intro and death reveals included some chatter between the Scum roles). The Scum Investigator never bothered to use her power on the Godfather (they knew that it couldn’t possibly affect the game state), but if she had, I would have told her that he was Town. If the game had been larger, the Scum team would also have had a third member, a Roleblocker.
