So we have...

Chief Pappy - Role Scanner
Chaotix - Double Voter
Darth Feather - Doctor (confirmed)
Ibn-Khaldun - Doctor
Makrell - Bulletproof (confirmed)
Visorslash - Vanilla Townie

Crossroad was also a vanilla townie, I believe the newbie trio were to bolster the ranks for the assistance of the town. Zain might've saw a balancing issue? Or perhaps a chance to improve the story?

Either way, I'm willing to bet Chaotix (Aaron Anduin) will be the hero in Pratia 4, so he's innocent too. That leaves Ibn-Khaldun an unconfirmed doctor (who hasn't successfully stopped a kill) and Visorslash an unconfirmed vanilla townie.

Like I said, I don't personally believe my group contained more scum, but that a vigilante of such remains.

So, Vote:Ibn-Khaldun for now.
