Very nice, DC!
I can see this working out just this way. Luthor goes after Clark when Lois turns him down and misses so badly that his attempt rebounds on him and kills him. And Clark would be like, "What happened?" for a couple of seconds until he saw Luthor's body on the ground behind him.
Anyway, I love Lois' befuddlement at the revelation and Clark's retreat to Switzerland to sit on a mountain. Lois calling Smallville to interrogate Jonathan and Martha would have been funny under other circumstances. Most of all, I adore the way Lois repaired the basis of their relationship with Clark - no demands, no ultimatums, no screaming or yelling or loss of temper, just letting her tenuous love touch his heart. Of course, he had to be receptive to her entreaties, too. I enjoy reading about a human, emotionally vulnerable Superman. That's the way I view him, so we are in synch there.
Keep writing, DC! You're one of the very best.
