"You know, it took me some time to wrap my head around Madame Professor's thought process in targeting LunaLilith last round," piped up Remiel, who had been listening intently to all sides. "But I think I finally figured it out:
I can how, if she were the Priest, she might think to herself: 'okay, if I keep quiet and am taken out during the night by the werewolves or the vampires, my ability will have been wasted. Therefore, I will endeavor to use it as soon as possible. But, obviously, I can't let people know what I'm doing. I will pick someone at random'-- LunaLilith in this case--'and when it looks like they're about to be lynched, use my holy water. If they're innocent, we will have at least one proven villager and I a potential ally. If they're not, well, at least we got rid of one monster.'
Unfortunately, her gambit failed when the village voted overwhelmingly not to lynch anybody. I believe the vampires, assuming that MP was the Seer and had spied on a Werewolf, targeted Luna during the night, hoping to eliminate one of their rivals. Naturally, when Luna showed up as a villager, it cast Madame Professor under a suspicious light. She was forced to reveal herself as the Priest.
I do not think she would have a reason to lie. Coming out as the Priest (or as the Shaman, in Queenie's case) is a double-edged sword; there is a high probability that you are who you say you are (because if you're not, then the real priest or shaman would almost certainly call you out). But the drawback is that it paints a big, fat target on your back for the monsters.
Assuming she's telling the truth--and I believe she is--I see no reason not to go along with her plan. We all agree to vote for Blythe. If MP is the Priest as she claims, she uses her ability. If Blythe is innocent, we know our sheriff can be trusted. If Blythe turns out to be a monster, well, that's one less monster.
If Madame Professor doesn't use her ability, then we know she lied and can certainly take her out next round.
Thus, I say we make MP put her money where her mouth is. In following her proposed plan, we will gain two pieces of information at once: first, whether MP is lying or not, and secondly, whether Blythe can be trusted.
Unfortunately for me, I cannot vote for Blythe. I have made a deal with him where I would not vote for him if he won't vote for me, and I have no intention of breaking it. I'm still trying to decide where to cast my vote under these constraints, but I urge you all to follow MP's plan and vote Blythe. The Bodyguard is still out there, remember, and can protect our sheriff if necessary. "
