Another point...

Ha, Brzovic, I beat you to the punch!
I will bring up a discussion point though - and that is Brainiac's references to the "duplicity" of the human race.
I think it will be one of those underlying themes that brings the season to a head. Clark's faith in humanity will be shaken - partly because Lana is lying to him about the spaceship, partly because Lex is lying to him about everything, and partly because of something I'm sure is going to happen with Jonathon Kent/Lionel Luthor.
Humans will be shown to be liers. And that's going to play in hugely as Clark moves to Metropolis, becomes Superman, and gets a job at the Daily Planet. Perhaps he will realize he ISN'T one of them, he is superior, and it's time to become something bigger than a normal person to help others.

Just my thoughts, I don't know how it will play out. But those closest to Clark are going to betray him in some manner - and that's going to be huge.
