Interesting story.
Why is everyone sad for Lois, it's not like she ruined anyone's life. Oh wait she did, and it was not just anyone it was a friends life she ruined. But, of course Lois will not get what she deserves in the end. She will end up with Clark and the whole Kent clan just loving her at the end.
You hit on my problem with this story. I do not believe canon Lois would have outed Clark without talking with him, getting his side of the story of why he was hiding in plain sight. After getting his story and having seen what she saw in Smallville she would have not outed him.
This version of Lois did not even give him the courtesy of talking with him and warning him before dropping the bomb. For once it has given her exactly what she deserves, an empty life void of anything but her job. Can Anti-K turn this around? Of course she can it is fiction after all. Should she turn it around? That is the question...
All that being said it is a very compelling story to read and will probably turn out OK in the end. After all Alt-Clark seemed to be able to live a reasonable life after being outed by Tempus so there is no reason that Clark could not do the same after all the hoopla has died off a bit. There have been a fairly significant number of stories where C=S was known by the public and Clark could lead a reasonable live although under a significant amount of scrutiny so the event of his unmasking does not HAVE to be the end of his world just a major change in it. The biggest difference is that Lois, his best friend and soulmate, was the one to do the outing. This will be difficult to get past.
You are correct that probably in the end the entire Kent clan will forgive her because that is what they do. Will James ever forgive her? Well that is possibly an entirely different matter...
