When Lois bent over to retrieve her pen, I first thought that Clark had gotten a view of her cleavage and that he was pointing out that she needed to adjust her blouse. The grin he gave her seemed a bit forward for Clark if that were the case, though.

He came up right behind her. His head was so close that he could smell her perfume, or was it her shampoo. Clark took in the scent then stepped back in shock.
This scene paints a vivid picture of how Clark's drawn to her. I'd love to have Jimmy catch Clark smelling her hair here. He could give Clark a good ribbing for it.

"It is a remarkable dichotomy. In many ways, Clark is the most human of us all. Then...he shoots fire from the skies, and it is difficult not to think of him as a god. And how fortunate we all are that it does not occur to him." -Batman (in Superman/Batman #3 by Jeph Loeb)
