I actually came out of my pre-death conversation with Frozen pretty satisfied. It added up with what I saw re-reading the Rubicon game. Then a Hero was killed last night, and that made me suspect Frozen a lot more.
My opinion for all concerned is as follows: Meta-Ridley should kill Winston Hughes. If Winston's innocent, Beskar has some serious 'splaining to do.
Any other scum that aren't on Frozen's team should kill him. I'm pretty sure he is scum, and if he's innocent and you all kill him, then you're not killing other people, and that makes other people happy!
