This far those who have spoken (I don't count the icers here):
Sauce has been very amusing and contributive and I'm inclined to think him innocent at this phase.
Boro is weird but in an innocent way, I would say, knowing his playing style.
Rune,
Di,
Ang,
Mith and
Mac seem all pretty normal. Nothing particularly alarming there.
Like pointed out by
Sauce and
Mac,
Legate is behaving oddly. I don't like the feel of his first post. (Maybe because I don't like pompoeus speeches...

)
Legate slightly worries me, though I'm not sure if he would be this bantery as a baddie.
Sixth is acting weirdly and in a way I could imagine a relatively inexperienced wolf to act. But he's not overtly suspicious... Anyway he's most probably going to get my vote as he's the only one who stands out...
