In the face of all that was done and had happened the story hinges psychologically with the obscenely symbolic dove. There is an anticlimactic resolution in that "scene". There is a man there who is now about to be "nobody" again without his absurd assignment. This 'late-flood" moment is, because of its abject immeasurability amongst the cataclysmic armageddonist apocalyptic extravagancies, shining to me as the most relevant one.
I'm tossing things about there for a spell (sketches underway). And I'll be proceeding soon thereafter.
