Rubik
King of Lorule Lounge
Kingpin clearly wants to establish communication between mafia members. This is just a guess but maybe there could be small groups of mafia around each don who currently can't communicate with the other groups? Seems to line up with kingpin breadcrumbing the names of the dons in his messages.
wonder if rubik and freddeh are fighting cause freddeh needs to become the majority shareholder of the daily bugle as part of his motivation
I think that's a reasonable theory. The kingpin posting style is pretty Storm-like, Vro is a pretty big into trying to hint things to allies. KoD seems like a likely Kingpin in general.
I'm not the majority shareholder of the Bugle.
