Looking into the fact that I too am slacking in trying to analyze the scenario... :/
I assume my suspicions on those who haven't tried voting and haven't really explained themselves (as it seems likely that they are trying to avoid suspicion) however, considering they usually vote to not lynch, it doesn't seem likely that they aren't paranoid of the fact that they may be killed, since they aren't trying to eliminate anyone as they know that they won't be killed by their own organization (or something). However, there is the problem of Dry Bones killing Boos and vice versa, implying that no one can be safe until either is dead.
Regardless, I have suspicions with Navi, since he hardly posts and never really gives a reason unless it makes him look completely innocent (I have my suspicions on other people, but would rather not go into specifics at the moment >_>")
Vote: Navi
And if I am wrong, it wouldn't be a huge loss (no offense) since he doesn't really help with lynching... @_@"
