My Analysis -
RUDI has revealed that he is the Vig.
If he is fake claiming, then he is definitely SK as a vanilla townie will never do fake claim. If he is SK then why he killed Master Bates in the first night? There are many experienced players like Ali, CK, asprin who can be dangerous for him.
If he isn't fake claiming, means he is the Vig. As PE said that Master Bates was not guided to post which means the reason behind killing Master Bates was wrong. If we shall not kill SK or role blocker blocks SK's role then this is going to be last day of RUDI.
So RUDI is Vig for me but why he revealed his role? What will he get by doing this?
