Evie, I want to make sure I get this point across.
I loved the story. I think it's outstanding. The understated conflict between Lois and Superman and his unconscious (or maybe not so unconscious) neglect of the separation between CK and SM was delicious. And I get that your literary background is more in fairy tales than, say, military history or detective/mystery novels. I'm an amateur historian and I tend toward military matters in that area, so I'm used to stories that have a definite ending, and if there's a cognitive disconnect in your ending the fault rests with me. I apologize for being more abrupt than I should have been. Again, this is an excellent tale that is well told, and I sense a Kerth nom in your future.
Oh, and if you do figure out the result Clark and Lois' brainstorming, please let us know. I'm certain it would be absolutely brilliant.
