To develop: not only is it frickin' annoying that Geoff Johns is again pushing his retcon baby down our throat - and like others have said, making it look like Kon is never going to have a storyline not somehow related to the evil half of his genetic make-up - but how does it make sense?
He's hung around with Tim Drake, and Tim is the poster boy for 'I lie to my mentor'! And Kon's a teen! Lying to one's parental figure = teenaged behaviour! How does that add up to Kon angsting over lying to Superman? What ever could give him the dumb idea that lying to Superman = Lex Luthor?!
