Chimmy was probably the saddest. It is like the planet kryptonite itself was against the pairing. If it was not Clark it was meteor freak powers if it was not that it was Kara. If Kara was away it was Brainiac or Doomsday.

As far as boring Lexana has on reflection looked worse then Clana.

As far as worst Lois and her Daily Planet boss was pretty awful. It made Lois look like an incompetent reporter.
