Now you might ask...what does Katsuki as scum tell us?
Well, for a start! I'd say it's a fair bet that SirCakez is town.
For the moment, I'd like to keep the townbloc intact: Aristophanes won't ever be leaving, but at least momentarily, I would
prefer
to keep Fate and Prism alive and around. drealmerz was more of Nacho's read than mine, and is also Gin's read, and thanks to respect in them both he, too, I would prefer to not touch at this time. Monokuma is an inventor we've got leashed, so there's that.
I realize that basically only would leave Vaxkiller and Aeronaut--I'm not saying those are Katsuki's scumbuddies. I'm more saying that, as of RIGHT NOW, they're the two who have the highest sorting priority in terms of "are they a scumbuddy?" or "are they town?".
