I think it was primarily Lana who told him to get over his sweats aversion. This has to be one of the most negative versions of Lana possible. Although, they really did not leave much room for a positive version of her in the show.
I was hoping the flowers were not from Clark. I doubt it. He learned what was up with the roses, so probably has almost as much of an aversion as does Lois. Plus, it just does not seem to be his style. He believes in being there for Lois, not just giving her things.
Anyway, red roses seem a bit much. White or yellow maybe, but not red yet. That is going a little too fast, even without the negative associations with Ms. Taylor's illegal business.
Lastly, I figure that if Clark wanted to give her flowers, he would do so in person, not send them by delivery.
