. . . realized they'd plotted themselves into a corner and had neglected to come up with a way out.
Honestly it doesn't feel like they planned ahead much or thought too deeply about anything.
I mean, at some point they make a point of explaining the background of the archbishop and babylon as both being invested into the well-being of the refugees and working towards a common goal with their respective organizations - only to then find their differences causing them to become enemies that can't reconcile over the question of "how".
But at the end babylon-woman just goes "that's childish" instead of some sort "hey look, we tried that, it didn't work, what makes you think it'll go better now?" or aaaanyyything else that'd even remotely connect back to this obvious parallel development ^^;
