The Powerpuffs know exactly who are the main scum according to the rules of the game.
There are also rules and restrictions for them voting scum.
So in the early days of the game it is going to be highly unlikely that the PP vote scum, simply because there is no need to.
I'd put it at around 95% that KM specifically did not vote scum and voted townies due to him being a PP - because thats what you want to do.
You want to vote townies and get nightkilled so you can clear them.
So Robbie and Cuthillius are basically cleared of being main scum.
Essentially a big wink from visor
