As with season one, the writing team came up with more "what if" episodes for the series, like season two's "Visitor", which came from the idea of, "what if someone showed up and Clark began to believe that he wasn't the last person from his planet." In the case of "Nocturne", "what if Clark had been brought up by different parents?" With "Nocturne", the episode is meant to be "an extreme version of the Clark story". As Gough explains, "Here's a kid with a condition, whose parents literally lock him in the basement. It's an extreme parenting episode—contrasting how these parents deal with Byron, and how the Kents deal with Clark." The episode also dealt with Clark's fallibility, in the fact that Clark is only a teenager, and he does not always have all of the facts; just because he thinks he is doing the right thing does not necessarily mean that he is. In this case, Clark believes that he is saving Byron from his abusive parents. Gough clarifies, "doing what he thinks is right, but ultimately unleashes the kid, and [Byron causes damage. Just because you have the power and you think you're right doesn't always mean you're taking the right course of action." Another "what if" episode was "Witness", which originally came from the concept, "what if Clark witnessed a crime and had to testify in court as to why he was standing in the middle of the road at 2 o'clock in the morning?" In the end, the court angle was dropped from the storyline, with Clark making an anonymous phone call to the Sheriff and eventually having to battle the three kryptonite powered thieves that he had witnessed stealing.
