impertinence is another I'm seeing in a new light since my reread. particularly from his interactions with nickle.
Both had gone after carl over his quotes in the pre day 1 check in phase.
his thought of it being only town vs a ghost, seemed like a possible slip. if he's mafia he wouldn't have had the town win condition in his pm to go off of and could think something that far out is possible.
He does go after nickle on many points but only give him the finger
not long after radish points out that that finger could be scum helping fellow scum and the follow up discussion between the raish and impertinence is when nickle votes himself
imp does vote for nickle but them takes it back after seeing his number 2 has the same vote. (yet he has no problem having a vote for the same player as his #1?? Also he's now going after someone who he couldn't "fathom scum playing that way"
after prof votes for imp. Nickle says way to much on why he won't follow prof's instincts this time. fun thing I just noticed early in the game one thing nickle said the odds of prof being mafia were just as likely as him being town.
