We could make speculations about how many scum there are. From the sounds of the rules, I'd guess 3 for each scum team. Would be a high ratio of scum though, at 35% of the town being scum. If there were only 2 on each scum team it would be less than 25% of the town as scum. Maybe 3 on one scum team and 2 on the other. Any thoughts?
