Mafia 112. Pirates of the HW Sea

Since I don't want a night kill, 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 Berber. And yes, this isn't a leak of an inactive player, but rather specifically because of the Berber, 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 he has potential good roles, which is frustrating.
3. Invite Ples to the gallows because he has an approximately 80% chance of being Mafia due to the block and the small number of peaceful roles on him.

Gentlemen, what do you think? Do you have anything to add?
