JoJo and others have come up with a different interpretation on Lois's probable reaction to the news that Clark and Superman are the same person. I don't disagree that she would probably be less angry if "Superman" made the confession than it "Clark" made it, but it points up something I touched on earlier. In this story, the Clark persona is taking a backseat to the Superman persona, especially in relation to Lois. Superman has become the dominant personality where Lois is concerned, so naturally Lois is going to get closer to him. Another poster mentioned that Clark seems to have channelled all of his geekiness and fear and insecurities into the Clark persona, and that's a large part of the reason that I agree that Lois would probably go ballistic at Clark but would probably be disappointed in Superman when either of them tells her the truth about the dual identity thing.
Ann mentioned that it seems that the laws of physics must work differently in the Superman universe for a pair of glasses to hide his true identity. I disagree. It's also the hair style, the suit, the body language, the powers, the voice, the facial expressions (my impression is that Superman frowned more often than Clark did in the series), and the apparent change of personality between them. If someone wants to pull off an identity switch, it can be done, and identifying these people usually happens either when they make a mistake or some civilian gives the cops a tip. Granted, it would be more difficult for someone in the public eye, like Superman, but I think it's feasible.
To bring this back to the story, Kal-El has suffered greatly alongside Lois, a situation which nearly always brings the sufferers very close together. Conversely, while Clark suffered alongside Lois (and therefore feels the same no matter what clothes he's wearing), Lois doesn't know that! All she sees is the inept, undependable, dorky klutz she works with. When he wears the suit, she sees the man with whom she experienced torture, pain, dehumanizing treatment, and perilous escape. Her attitude towards both men is completely reasonable and completely understandable. And I still think there will be some huge speed bumps when she finds out, whether he tells her or she figures it out herself.
Can't wait to see whether or not I'm right. Or even close.
Almost forgot to ask, Rachel, how did the date go? Well, I hope! I hope you had a nice time with a nice person.
