What difference does it make which mafia we find, if they are probably there? I just don't believe that the mafia would start on the second day, without any particular problems, and unanimously eliminate someone in their favor.
On the contrary, among those who voted against Mental, there is definitely 1 mafia, and maybe more. Let's look there, since they are there, that's the most logical thing to do.
And the argument "between Master and Mental, he chose Mental for elimination" has some basis.

В тихой однообразной жизни всегда так бывает: каждый отдельный день бесконечно долог, но месяцы и годы мчатся с непостижимой быстротой.
