Ack! Me too-- I can see the potential here for lots of angst. (Sigh... I'm not as fond of angst as some you other Folcs are...)
I do, however, agree with Raquel and SJH-- how could she not know they're the same man after that kiss-- much more emotional (and probably more intense) than any other kiss they've shared in either of Clark's guises? How can he kiss her so passionately and stay in Superman's character? He's heard her say she loves him-- how can he not tell her he loves her "too"? How could she not murmer Clark's name and he not respond to that?
I can still see a lot of angst ahead, in the form of Lois' reaction if (when?

) she finds out. And I agree with Tank about the only way out for Clark is probably his certainty that "Clark" is dead.
But I really love TOGOM rewrites-- almost as much as Nightfall rewrites (especially if either involves revelations), and I
particularly love
happy ending ones! So that puts me squarely in agreement with almost everybody else in hoping (begging?) for a happy ending.
