Mermaid aside the game looks to me like
LL/TL - not mafia
Porsha /Falcon/Illunga/Tanev - not sure
DM/NIK - probably mafia - I am actually inclined to think DM is more likely maf out of the two due to first round wagonomics. I have no doubt that scum avoided the SD vote best they could especially since the two wagons of SS and SD were both townies.
Imma unvote; vote DM
For now.
