I think Lois had a mixed reaction to the byline, and that's why she wasn't as excited as you might expect.
Yes, she REALLY WANTED her first byline to be "Lois Lane." That was important to her identity. Even "Lois Lane-Kent" wouldn't be too bad. It still shows her identity as Lois Lane, while acknowledging that she is married.
She told Clark as much in the last parts.
BUT she also knows it's not really save for her to be "Lois Lane" or even "Lois Lane-Kent" while Navance is still at large.
"Lois Lane-Kent" still recongizes that she's married, yes. But in someone like Navance's eyes, it's a sign she's not fully committed to him. He could use that against her.
Their have been rumors that Navance may be taken out, etc. But they don't know that yet. Quite frankly, I wouldn't put much faith in the rumors, either. How many rumors have there been that Saddam will be taken out over the years? (Okay, so he was, about five years ago, but that was years later.) Or Bin Laden?
Untill they have difinitive proof, they can't tempt fate.
The Daily Planet may be hosted in Metropolis, but it is known in the LNC universe as an international newspaper. What are the chances that Navace could get ahold of that paper?
Of course, now Clark is tempting fate by creating Superman. I can understand his disire to help, and like I said in the last FDK thread, I think it will make a good plot divise to bring Lois and Clark together for good.
BUT he is tempting fate.
I wonder if they have gotten a little lax on the threat of Navance in the last year. Or at least Clark anyway, because he's the one who made these desisions. Certainly, it's always in the back of their minds, but threat doesn't seem as dangerous to him, given his actions.
Lois is going to blow her top for doing this and, hence, in dangering Christopher. (Of course, you got to figure the recent rescue way more of a split-second decision than "I think I'll have fun saving people without telling Lois today.")
Although, if the threat to Navance is only in the back of Clark's mind right now, you've got to wonder how that affects his view of his marriage...? After, all, he always said he's only staying because of Navance.
And the was he was insulted when Dr. Baines flirted with him was interesting, too.
Of course, you could make the argument that he just isn't interested in HER.
And he always said he wasn't going to cheat on Lois because it was wrong.
But still...sounds like an emotional reaction to Lois to me.
Love this stuff.
