I do NOT have a negative reaction to Clark Kent and Lois Lane-Kent having a relationship in the future. If Lois had grown up around Clark from their pre-teen years, then she would have developed a brother-sister relationship with Clark (like Lucy surely has). You'd have a problem with a romantic relationship between them under those circumstances.
But Lois didn't grow up around Clark as her 'big brother.' She didn't even live under the same roof with Clark very much. Incest isn't part of this equation. If Clark were to romance Lucy (after her 18th birthday, of course), then there would be legitimate concerns of psychological incest in that relationship. But not with Clark and Lois, irrespective of the 'soul-mate' link they may or may not share.
This is an interesting story, one which should be given a chance. I've already read part five, and I like what's happened so far. Keep it up!
