Its just a setup theory
So
N1 1 kill (vig)
N2 3 kills (scum, mafia, vig or mafia, mafia, vig)
N3 1 kill (vig)
Swoosh blocked Bcb N1. If swoosh is town we know bcb was town, so that didn't stop a hit
Swalf jailed Rags? If Swalf is town we know Rags was a coward and probably not a SK, so that didn't block a hit
Mafia/scum didnt have a hit N1 and most likley N3
