I imagine there would be a lot of arguing between the faction of 'We shouldn't interfere with the humans, we should just build up our tech base and go to a new planet' and the 'We should rule the humans because they're primitive and weak, and why should we waste all our efforts trying to get to a new planet when there's a perfectly good one that we're standing on right now?' Jor-el would be in the former faction, probably. BTW, Sol-van is Kal-el's grandfather. I like the Greek gods idea, the latter faction would probably pull the 'But our ancestors ruled this world, so should we!' card, citing them as precedent. Jor-el would encourage his son to go out among the humans in disguise and mingle so he would understand that humans and Kryptonians aren't so different...and Kal-el meets a very fascinating human named Lex Luthor...*plants plot bunnies, PLANTS THEM EVERYWHERE* *also mixes her metaphors* *because you can't really plant rabbits*
