So here's my dilemma. I think there's a strong case to be made for either KY or Brigitte to be scum. Besides average scumminess, there's a few key reasons I'll summarize below.
Killing_You:
If we look back at the previous day, there were no scum targets up there for the lynch. No matter what happened, scum weren't at risk. If KY believed that Mojo was innocent, why would he voteblock Orange and then not vote for a no lynch to guarantee that the confirmed town doctor lived? You could chalk it up to bad thinking or a scum move to try and gain brownie points while leaving the chance for two non-scum to get lynched. Either way, looking back over his posts I get the feeling that he was generally softer on Orange and more aggressive towards other players like Brigitte.
Brigitte:
A glaring problem is that Mojoman, a confirmed doctor/tracker, claimed she visited a target N2 and she claimed otherwise. She also held her vote on Mojoman and has a day kill immunity. This would mean that all neutrals are day kill immune, one town is immune (Louis, I think it's safe to say she's town), and then Brigitte's claim. It would fit kind of nicely for mafia to have their own immunity given all the day kills floating around. Then again, that could have been Orange if he really did have an extra life.
Between the two I'm honestly not sure who it could be. Will need to hear from Brigitte and think some more. Anybody else have some thoughts?
