<P> For season three, Mack wanted the character to be given a major obstacle to overcome, something that would help the character mature . The obstacle in question became Lionel's control over Chloe, after she made a deal to spy on Clark . Allison Mack believes that Chloe is in her own comfort zone while she is working at the Torch, as she is in complete control, but likens Chloe being under Lionel's control to that of a "caged animal". When she ruins the lives of a mother and her son in season three's "Truth", after exposing the mother as a fugitive from the law, Chloe is forced to look deeper into her own self . Mack believes that this event was a turning point for Chloe's maturity; it is the moment that she realizes that there needs to be a line she should never cross . After it is revealed to Clark in the season five premiere that Chloe knows his secret, the character becomes a larger part of the storyline for the show . Knowing Clark's secret allowed Chloe to finally come to terms with her feelings for Clark, and recognize where their relationship will always be; Chloe's acceptance of her place in Clark's life provides a means for the two to have a more meaningful friendship, without the concerns of Chloe's unrequited love . According to Mack, Chloe has learned to evolve her love for Clark into something more "genuine" and "selfless". </P> <P> For the actress, having Chloe become part of the meteor infected community in season six allowed Mack's character to continue to evolve . Mack views this transition as a means for her character to become more emotionally connected to those people--the meteor infected--she spent five seasons trying to expose to the public . Being infected by the meteors gives Chloe motivation to try to understand them and allows her to grow closer to Clark, as she can better understand what it feels like to live in a world where you have a special ability . Writer Holly Harold believes that, in addition to being infected by the meteor rocks, bringing Lois into the journalistic field also provides Chloe with a lot of ammunition for growth and development . Lois's presence at the Daily Planet allows Chloe the chance to reflect upon herself, and discover what things are most important to her--her career or her family and friends . The competition that Lois provides is beneficial, as it gives Chloe a chance to bring out the best in herself . </P> <P> Allison Mack characterizes Chloe as being a "misfit" during the first season; more of "a really smart girl with attitude". She goes on to describe Chloe as intelligent and independent . Another of Chloe's defining characteristics is her need to "expose falsehoods" and find the truth in every situation . The character is curious, and wants to be honest with people . She is always trying to make sense of the situation . Next to her curiosity, her impulsiveness is a key characteristic that eventually leaves her under the control of Lionel Luthor, when she offers to uncover information on Clark for Lionel . The reason for this betrayal is based on Chloe's love for Clark . As Allison Mack explains, Chloe is so blinded by her love for Clark that she neglects to see all of the mistakes that he makes . It is this unrequited love for Clark that "drives (Chloe) to be as ambitious and as focused as she is". </P> <P> A leading theory among audiences was that Chloe would eventually change her name to Lois Lane, Clark's wife in the comics, as she embodies various characteristics that Lois Lane has in the comic books . The creative team removed the notion that Chloe was going to turn into Clark's future wife when they introduced Lois Lane in season four . Though the characters share similarities, according to Mack, Chloe and Lois are more "different shades of the same color (...) Chloe is a softer version of Lois". Chloe's upbringing allows her to be less jaded than Lois . Chloe also looks to the future, whereas Lois is more shortsighted . </P>
