I was just re-watching the and I noticed that in the introductory credits they do not credit K Callan and Eddie Jones but they do credit Elizabeth Barondes. It seems that they originally planned on making Lucy Lane a significant part of the story of the show, but for whatever reason she very quicly vanished from it after the first 3 episodes. I think it was a missed opportunity, but I guess a Jimmy/Lucy relationship would have detracted from Lois and Clark.
