3 town roles x 1 first mafia x 3 second mafia x neutral x neutral
We execute Plesen, after night 2 x 0 x 2 x 1 x 1 or 3 x 0 x 2 x 1 x 0 (which is more likely). This means that without Zero's support, we CANNOT execute anyone during the day. And Zero might not support us. At night, there will be no kills, and I will most likely be killed. That's it, we're done. If during the day you figure out who Zero is and try to execute him, you will succeed, but then the mafia will have nothing to lose and can easily finish off the town. So, this is an obvious scheme for a mafia victory (possibly with Zero). The town has no chance. So, I strongly recommend that the remaining town and Plesen support the execution of the separatists.
