I was thinking that since Lois called him Superman when he woke up, even though she knows he's Clark, then she probably found out because he was talking in his sleep or something.
Edit: I had originally asked someone, I will not say who *ahemjulieahem*, to write part three, but last time I talked to her about it (which was actually very long ago) she said she hadn't even read part two. So, if anyone wants to take the responsibilty off her hands, please feel free to do so.
Of course, until someone else volunteers, Julie is not off the hook so:
Nag Nag Nag Nag Nag!
