Let's look at it this way, she is Lois from another reality, she is attracted to Clark the same way that Lois is, how can she help it?
I agree. I don't know much about Margot other than what you've shown us, however it appears she may not have Lois's history of disaster relationships with men, which may account for part of why she seems close to Clark so quickly. Plus, if she's not either as adventurous or as independent as Lois is, she may be attracted to Clark for support. After all, she's far far away from her home and her support system.
Enjoying the two parallel stories!
