Hey HappyGirl!
I wish I could take credit for the idea of having Lois and Clark be each other's Audience of One, but it's actually not mine -- it's the show's.
Lois and Clark are supposed to be soulmates. The idea is that they end up together in any universe, and deep down, they've always known they should. This is my take on that.
For Lois, at this point in her life, it is of course Superman and not Clark, but that's just because she doesn't yet realize they are one and the same.
I think writing the story this way adds a certain intimacy to it that I like; it's also a not-so-subtle kind of foreshadowing, but then I've rarely (if ever) seen a Lois & Clark story where the two do NOT eventually become soulmates in every way -- so I don't think I'm really spoiling anything by doing this (or telling you about why I'm doing this).
What's true about so many things in life, including life itself, is also true for this story, and for pretty much every LnC story out there: it's not the destination that counts. It's the journey. As LnC fans, we all know where the journey leads, and yet we keep coming up with new ways of getting there.
There are certain constraints to writing in this fandom, BECAUSE we all know what the outcome will be. But I've found that constraints like that can actually be a great stimulus to get creative -- and I hope the journey I come up with will be a fun trip for all of you.
