Ok, so the three possible scenarios.
Scenario 1: Hedger and Zhuorb are mafia and trying to frame me as I've been gunning for Zhuorb and in turn have picked up some suspicion. Killing BKB was an obvious choice - the doc was going to protect Colin/Pd/User, and BKB lynched me so that would make me easy to frame. Zhuorb messed up his reasoning though, and his desperateness is obvious. This is the most likely scenario. Although pd being Miller is weird, but then BKB did have a one-shot investigation.
Scenario 2: Hedger is the cop, and I'm mafia. Colin is my mafia partner as he's said that he tracked Hedger and found that he didn't target me but BKB. But then how do we explain Zhuorb's desperateness, and the presence of virtually two cops in the game, and no preventive roles whatsoever? (I presume Zhuorb isn't claiming doc or something?) If I and Colin are mafia, and Zhuorb isn't doc/jk/town roleblocker, then after BKB's death the town doesn't have any preventive roles. User has claimed to be a vanilla townie.
Scenario 3: Someone out of User2010 or Puddleduck is mafia. That seems unlikely although the thought of there being a mafia framer did come to my mind. But with the presence of miller, that'd make mafia very overpowered, considering that Pd isn't himself the framer.
Scenario 1 is easily the most likely one, although with my role, and claims of Colin being my partner (no one trusts him completely) I don't think it's fairly obvious to everyone.
----------
Zhuorb is about 80% mafia but unless there is something very strange going on hedger is 100% mafia.
Don't quite understand why Varun, despite hedger claiming a guilty result on him, is more keen to lynch Zhuorb.
Becuase Zhuorb is confirmed mafia for me. Read scenario 3.
