I'd love to see the explanation for the Superman comic book that Chloe was reading to her son. My theory is that Clark somehow crossed over into our world and found a comic of his own life, then decided to take it back with him. The only issue I'd have with that is letting the kid in on the secret. I mean, how could they possibly know he wouldn't blab that around to all his little school friends?
I also want SV's John Henry Irons. Still pissed we never got him in the series.
