Mortulus is already a suspect for everyone. Tsvetok wasn't actively involved in the game regarding the town. And now, suddenly, this strong civic stance.
There are two possibilities:
1) Tsvetok wants Mortulus to be eliminated. I'm more inclined to believe this.
2) Tsvetok wants Mortulus to *not* be eliminated. I would believe this, but on other platforms, where the game dynamics are different.
Let's analyze the first possibility. Why would Tsvetok want Mortulus to be eliminated? a) Mortulus isn't a knight.
b) Mortulus isn't a Mafia member at all.
If Mortulus isn't Mafia, then the Mafia member could be, for example, Nefela. I didn't see any hints pointing to her, and I couldn't find any other way to investigate (and even then, with reservations). The rest of the players are irrelevant to this.
If we assume that Mort and Tsvetok are partners, it would be easier for Mort to use his power and influence, rather than appealing to the town's reason. Overall, it seems too simple that two obvious Mafia members are so easily identified.
Mortulus, in your opinion, who are the Mafia?
