I'm thinking the remaining scum are N0M, Barry and either CP or OMB.
Barry was super eager to vote Chris when it seemed like the wagon was closeish to making it to a lynch, which looked scummy as fuck in a "let's hope this wagon makes it before people use their heads" kinda way. Also I feel like he's gotten more and more quiet as the game progressed and overall he's my top scum read atm. If Barry is scum I can safely rule out Chris from that vote Barry made.
N0M is a weird one cause his reaction to Odo constantly putting him down seems genuine in the same way Alcos reactions earlier seemed genuine, but I also can't deny there's just no play to read him from and that's simply not good enough at this stage of the game.
Third slot is POE where I've run out of reasons to clear CP and OMB is just up in the air, pure POE fodder. If Barry is scum I think CP is a good bet for the third slot cause of the scum team he just suggested.
Clearing Odo on play, Lethal on role, Rugrat mostly on play though it could be him but I'd be very surprised if it was.
