I agree that thinking up new revelations is hard. But even worse in my opinion, is figuring out how to write the follow up.
Normally, Lois gets mad.
Oh, the angst.
Oh, the yelling.
Oh, the drama.
Will she ever forgive him.
Yada yada yada.
Sometimes it's almost like 'oh, just get over it already so that I can get on with writing this story.'
Someday, I'm going to write a story where Lois is like... "Really? Huh. That's interesting. So, Clark, were are we eating supper tonight?"
