Well, Season 2 opens with us as the viewers knowing that a-Lois loves Clark, even if she has not admitted it to herself yet, b-Clark loves Lois, even if he lied to get her to believe he doesn't, which she may of may not have really bot. So Lois is at least somewhat past her attraction to Superman, but Clark does not know that yet. So the whole thing moves towards Lois learning CK=SM, but in the show they postponed that point as much as possible and then some, so there are lots of angles that move to the reveal faster.
