I always thought it was the other way around. Clark is the real person and Superman is the "act". Maybe it's because what Lois & Clark did with the character made an impression on me. Well, if you want to get technical, every version of Superman is its own universe. That's not something that's unique to Smallville. Anyhoo... I'm not happy with what they did to Jimmy. Did DC really panic and make the show runners kill off the character? I'll admit that after seeing the episode, I was glad that there would still be a "Jimmy", I'm just not happy that they had to do a retcon on the one we knew.
