Just one thing to add, Terri-

And, after all (re my suggested title), if the gods had ever wanted Kiril NOT to raise his Mum's sword against them, They had only ever to say so.....

But, in this culture, to do battle with the Gods is the height of piety! Thus the last line of the story - in both its retellings. Well, all three at this point.

But that's exactly why I love your title so much. It gets at that paradox even for people who don't know anything about the story.

Thanks again; I really love your suggestion!
