Nicely written, but I felt dread and trepidation as I read that you intended it as closure to Ad Astra Per Aspera. Becky's story was extremely well written, but I thought it was the saddest fanfic that I've ever read. I keep telling myself I'm going to try to re-read it and see if I have the same reaction. And yes, Becky very much intended to story to be as she wrote it. But even though I felt dread and trepidation, I was seemingly morbidly drawn to your story.
That said, it was interesting that Clark and Lois became Jer-El (don't think much of that name) and Loia. Lois of the House of Us. Cute.
And as I said, it was nicely written, but I wonder if you shouldn't remove all references to Becky's story. I know you changed the names, but you still note that you wrote the story as closure to Becky's fic. In that story, Lois was very much in love with the man she married.
