I like it, too. The hints that there was a second super-clone, the imminent danger that Leviathan poses to our favorite super-couple, the nearness of the rest of the Lane family (who seem to make good candidates for the WHAM you warned us about), your warning about Dark Superman (about whom I'm already wondering), the easy banter on a Monday morning, Clark's failure to discern between Lois and Lucy (which might also foreshadow an important plot point), and the general high quality of the prose all make this one of the stories which I hope continues quickly. Even this early in the story, the new characters are well-drawn, the conflict has been defined, and the participants have been introduced swiftly and efficiently. I'm looking forward to following this one.
As Bette Davis once famously said, "Buckle your seat belts, it's going to be a bumpy ride!"
