Andor, prestige television, and the elements of greatness
This strikes me as a plausible read. I am rather curious how the needle will be threaded with Luthen, I hope that it will be managed in such away not that all that feel the call of the Dark side are in fact secret conspirators with one another so much as the cycle of feeding off one another that you describe.
That said, I'm always a sucker for a good ensemble piece and I'd think that some of the story is people figuring out their role, as you mention, and just how far to push it versus accepting the legitimately conflicting priorities of others in the rebellion. We're not really at a coalition politics stage yet but I think it will not just be Mon's individual choices and sacrifices but also her interactions, balancing, and choosing when to accept a compromise pushed by another that will be vital in her evolution.
