How about the reverse. Zara shows up early and is traveling with Clark trying to convince him to come to New Krypton when he gets to Metropolis?
Or she fled after Nor toke over and plans to stay on Earth and is staying with him because of the arranged marriage. Two super aliens one of each sex will really make Trask and Bureau 39 freak out.
For a twisted B plot, Lois won't think about getting involved even as a close friend with a married man and Clark won't do anything since he is married but Zara can tell because of Kryptonian telepathy that they are soul mates and should be together.
This goes with the Clark already married discussion from a week or so ago I think.
