Clark's attachments though are also what gives him his inner strength that is something that Jor-El will never be able to understand. Jor-El is thinking like a scientist where it concerns his son. He's not the passionate young Kryptonian who fell in love with Lana's aunt or whatever when he made his rite of passage journey to Earth as Joe. It's going to be interesting to see how the young Jor-El is portrayed since we only have Tom Welling's performance to base him by.
The writers in Smallville have always created their own problems...particularly the need to reintroduce Lana and wrap up her story line. To me I'm ignoring the whole Kryptonite woman arc and Lana left Smallville for Paris or wherever with the DVD breakup. That arc should have never happened...I wonder who requested it. I doubt that Kristen really wanted to come back for it since she had been spouting off about her dissappointent prior to that and discontentedness with the role even after the wedding to Lex.
