I say we go after the ringleaders. These would be PK, Craterus, and TinCow. There's a very good chance that one of them has successfully infiltrated as Jotun and screwed everything up. There's no way that a "network" could be this counterproductive on its own.

And BTW, wasn't there a bandwagon on CR earlier in the game, sometime around when everybody viewed me as suspicious? Take a long look at those people as well.
