Assuming confirmation they were both townies.
We have 1 Godfather, 1 Mafia, 1 Cop, 1 Sheriff, 1 Doctor, 1 Vigilante, and 2 Townies left.
This should be pretty easy ladies and gentlemen.
I am a townie. The cop knows that.
If we all disclose our roles right now - the only people left are the mafia. They will lie about their roles, sure, but then we will have a 50/50 on which one is lying..... If we hang the wrong one, the vig can kill the other.
This game is an easy win for the townies.
