I'll try to keep it simple:
Joebob (you) are definitely clear because you claimed bodyguard, and no one else claimed.
I know that I am clear, leaving Pie, RM and GP.
RM and GP are definitely working together, as we can see throughout the thread.
Thus, there are only two options for the mafia: RM + GP or Pie. Since I know there are two mafia left, it has to be the former two.
