I'd rather think of Lori coming to Metropolis because Clark has been broadcasting whiny thoughts. Picture her after your tale, heading back to Atlantis
Spearcarrier: "Did you solve the painful whiny thoughts problem?"
Lori: "Yup, some people you have to hit with a rock, some people need a really big rock*. These two needed an Asteroid."
I fell out of my chair on that one!
