Coming into this late, but wanted to say this story is intriguing.
I find the twist in alt-universe/alt-timeline you use here quite compelling.
Not sure how you are going to be able to wrap this up so quickly and answer all the questions I have but definitely interested to see where you take this. In particular one question I still have is what was the operation performed on Clark. Will we find out?
Thanks for posting something thought provoking.
