Nominate RTC. If he has the aggressive style no matter what his role is, then we are hardly going to get any helpful read on him. So the least we can do is lynch him and see if we get any info out of that.This is my normal playstyle. I do this both as Mafia and Town, in order to establish a strong meta if I'm Mafia, and contribute to the best of my abilities as Town.
I can show you previous games to prove this on other forums.
I do agree that Perun seems suspicious, so whatever outcome comes with a potential RTC lynching would hopefully come with a clue there. Regardless, I think it'd be a good idea for whoever the cop is to check RTC or Perun next turn.
