The Blacks can sabotage (bluff) or ignore the vote. Or they can vote, trying to portray themselves as Whites, of whom there are more.
If Gur is one of the White Rooks, we would have already known about it, I believe. It's not a good idea for the Blacks to expose themselves like that, because the Rooks will realize that there's a lie in the thread. The Whites have no reason to do so if Gur is not a Rook.
There will be interesting revelations, I'm looking forward to reading them.
So:
1. If Gur is Grey and we guessed correctly, that's a plus for the Whites. Minus one murder for the Night. There will be a murder of Whites + a murder of Blacks.
2. If Gur is White, and we guessed incorrectly, that's bad, of course. But it's important to know who we guessed. If it's Pawn F2, it's not a big deal. If it's something more important, facepalm.
3. If Gur is Black, then we also have something to be happy about. We will roughly find out who he is. And the Blacks will be in a really bad situation. And it won't be long before we get to the Black King.
Night plan for the Whites.
1. The Rooks can do whatever they want. But here are some suggestions.
1.1. If Gur is Grey, then you can kill Arandor as an obvious Black. I wonder, was his statement counted as a reveal?
1.2. If Gur is not Grey, then it's up to your conscience and desire.
1.3. Keep in mind that Arandor may be protected. Pawn E7 is dangerous for you.
2. Knight B1, steal a vote from any obvious Black.
3. Knight G1, heal an obvious White. I recommend Wolfstet or yourself. I still trust her. But do you trust her? Or do you have someone more worthy of trust?
4. Bishop C1. See recommendations for the Rooks (point 1).
5. Pawn E2. You can protect Wolfstet, in principle, or another more worthy White, whom you know or suspect.

If anything, I'm off to a corporate event. I'll try to read the forum.
