NNV is definitely not a good idea; it would be a huge gift to the Mafia, and they would thank us for it. And I still think that Ment is a better choice. Besides, it seems like he's just ignoring the fact that he's being targeted.
If Ment turns out to be a bad guy, the next person we could investigate is Arandor. I wouldn't be surprised if Gibil decides to steal his Night Vision.
If Ment isn't a bad guy, then it's a tragedy, and I won't play this game anymore.

Neyra, name two players that you understand better than others.

Understand in what way? In the sense of "I'm sure I can trust them"? Right now, I'm sure about Medge, because both the newspaper and his reasoning support him. I don't understand the logic you're following, but if you're not a cunning manipulator, then you're peaceful in my eyes. I would also add Kosh to this list; I like that she's against NNV.
