Thanks, Sara, robinson, and Patrick!
Yes, Sara, that was what made me decide Clark would appear as Superman. Well, that and as I never understood how she didn't guess Clark's secret when he scared off Superman in her apartment. Still, the idea of Lois thinking there were more clones was very appealing.
I think Superman's memory issues will become clearer in the next set of chapters.
As ever, Patrick, your ideas make me smile. Would Superman's memories change because someone was messing with the timeline in his universe? I don't know.
