Clark reached out, took her hands in his, and made a show of inspecting them. “Now I understand,” Clark said as if he were addressing her hands. “Well you two need to behave yourselves. Remember that Lois can’t break stories from a jail cell.” Then he paused as if in thought, then addressed her hands again. “At least it’s a lot harder.”
Ahahahahaha! Oh Clark, you are TOO cute!
But gee, why would anyone think that they are dating, holding hands and all?
Her fleeting look around the room had caught Madge nodding her head with what looked like a satisfied smirk on her face.
Ooooh, maybe Lois will figure out that SHE is the one who is suppossedly dating Clark!
The instant she’d seen that look on Madge’s face a while ago, Lois had a sneaking suspicion that she herself might be Clark’s supposed significant other.
Oh yay! Nice!
“What do you mean, the way we act? We haven’t been sneaking into the storage room.” Lois could hear her irritation leaking back into her voice.
Oh but you *should* be Lois.
“Clark is always friendly. But you must have noticed that there is his everyone else voice and his Lois voice.”
I just adore this line.
Then she remembered the other night. “That was why you called Clark’s apartment to reach me.”
*in my best Tempus voice* DUH!
But this was Clark. Somehow that was enough to make a difference.
Oh just admit it Lois, you're smitten with him!
Loved this part! Although I thought for sure Lois was going to confront Clark over who he is supposed to be dating, denials on Clark's part, disbelief and anger on Lois' part.
Anyway, glad Lois figured it out. Can't wait for part 3!
And spending every evening together, whether on work or personally.
--but I love how you explained it here with the differences in his tone. I can't wait to find out how they think of Lois's differences around Clark.
