Hold the phone... you can vote for No One? Oh God, that is so totally awesome!
I never knew that. I've never seen it done. That's what I love about Werewolf: you might think you know everything about the game, but it still can manage to surprise you.
Time for some logical thinking:
If Diaz is a priest, then he will be protected by the other priest, if any. If there is no other priest, he will be killed during the night.
If he is a wolf, he will be protected by the true priest and possibly even the real priest, meaning both our priests totally wasted their role and it will allow the wolves to mercilessly kill anyone they so choose.
Either way, this is a double-edged sword. If we vote for Diaz, we risk the loss of a priest, if not our only priest. If we let him live, he might be a wolf and there will be no protection for any of us. Either way, this is an immense gamble for the town.
If we kill Diaz now, we may lose the priest and any last form of protection. But if he is a wolf, then we will be infiltrated by the Werewolves.
But when Diaz said he was the priest... I truly believed him. My gut shifted as I contemplated his possible innocence, and I realized what we might be doing. Therefore, I recast my vote in a way I never realized was possible. Not because my logic tells me to do so (and indeed, it warns me heavily not to do so), but because my gut tells me it's the right thing to do.
Unvote: Diaz
Vote: No One
But Diaz... if you are a Wolf... then I swear I will do everything in my power to rid your presence from this game. I will be keeping heavy attention upon you, and if you act up even in the slightest manner, then you will know exactly who I will be voting for. If you are the priest, I apologize... but if you are a Werewolf, then I caution you.
