Revealing mistake: When Lana has her nightmare, she wakes up in a room and discovers various people on pedestals, underneath body sheets. During the scene, some of the people under the sheets can be seen lightly breathing, although everyone under them is dead.
Factual error: When Lionel is leaving the prison, there is a bus unloading convicts as he walks past. No prison in the world would ever unload inmates and release an inmate in the same area at the same time.
Jonathan Kent: Are you okay?
Clark Kent: Can I answer that in about five years?
Jonathan Kent: Yeah.
Clark Kent: Dad I'm glad you and mom are the ones that found me.
Jonathan Kent: We didn't find you, Clark, you found us.
Trivia: Jerry Siegel, the co-creator of the Clark Kent/Superman character worked on a school magazine when he was at Glenville High School, Cleveland. The magazine was called The Torch - the same name of Smallville High's school magazine, edited by Chloe Sullivan and with Clark Kent as an on/off contributor.
Question: Throughout the series, people mutate fairly soon after their exposure to kryptonite. Is it ever explained how Lana has managed to wear a piece of kryptonite around her neck for 12 years and not change?
Answer: The kryptonite only creates mutations when it reacts with the environment and an individual. Remember, the FDA and several environmental groups did check out Smallville after the meteor shower, but found no danger in the rocks. Obviously they're not always emitting mutating rays, or all the flora and fauna of the surrounding area would be horribly mutated.
