I'm saying that clues don't provide the same guarantee as facts. And you had the "pleasure" of seeing that. And yes, the Mafia doesn't have a "priority" at the beginning of the game when the town is still relatively large. It's only when the number of Mafia and town members is roughly equal that they do. However, it seems pointless to try to prove anything... After all, I'm a maniac, and "you can't trust a maniac"...
Cultist is strong when recruiting, but they're hard to find. Joconda was and remains alone in the town.
And the fact that you can't trust Manu is just your own personal bias, Mr. Lizard.
The clues weren't definitive, but the solution was good, it just didn't work out.
