And if Rej is not scum or Indie?
Rej gameplay was weird, so scums have more reasons to push a case against Rej, rather strongly in this case, since it's easily believable why someone would think he is scum.
But like Queen pointed out, Rej is veteran acting D1 this way. A Mafia won't do this, unless ofcrs to town clear someone, or he is indie with such role, or a townie with bad role and he is rewriting his meta with a destructive gameplay, while enjoying North Korea role.
As for him being confident and aggression, maybe bt it's not solid for me.
