Since I don't want to trigger a night-night vote, I'm willing to consider the following options:
1. Execute Arthur on suspicion of being a tentacloid. The fact that Nebo found something on the snail speaks in favor of this. I don't rule out that it's a Barbarian. And yes, this isn't a leak of inactive players, but rather specifically because of the Barbarian, Nebka.
2. Grab Fragment by the scruff of the neck. He's suspicious. And I have my own reasons not to trust him. The problem is that there are supposed good roles on him, which is frustrating.
3. Invite Ples to the gallows, because there's an approximately 80% chance he's Mafia due to the block and the small number of peaceful roles on him.
Gentlemen, what do you think? Is there anything to add?
Well, the solution is so-so. I would rather support executing Ples than executing based on my Barbarian.
