Clark's insecurity about aging is one of my favorite things the show has done.
I feel like we're heading toward a "Whatever Happened to the Man of Tomorrow" kind of ending, and this may be the first time in Superman media that such an ending would feel right to me.
My one complaint about this episode - that NONE of the superpowered Kents heard Lana's distress from only a few miles away - was addressed directly in the show, and while I still don't quite buy it, I can live with their explanations.
Really loved the Smallville residents stepping up against Luthor. And I'm enjoying how the show's handling Clark's secret becoming a rather open one.
