Personally, I have always thought Dr. Klein was terribly mistaken and if they would have gone on for one more season, they would have been able to better understand what happened. But, since they didn't, that leaves it up to us fanfic writers
Hurray for fanfic!
Completely agree with you on this, Laura. I'm sure Jor El also investigated that angle. Why would he send his son to a planet if he wouldn't be able to really mingle with the people there and have a normal life - in all aspects?
