<P> While in Paris, Lana begins a new romantic relationship with Jason Teague . Kreuk believes that Lana did love Jason Teague, but she also still loved Clark at the same time . With Clark, it was the "first love" that she never had the chance to discover, and that lingered with her while she was in Paris during the space between seasons three and four . According to Kreuk, before Lana can experience successful relationships with other people she will need to know what it is like to truly be in a relationship with Clark, because of the "intense connection between (the) two". Allison Mack shares her insight into the relationship between Clark and Lana, believing that the pair should have remained apart until they could finally be honest with each other: "There's no honesty in their relationship, and there's no way that they could have a healthy relationship without that honesty (...) You can't be with someone if you're not honest with them ." Kreuk echoes Mack's sentiments, acknowledging that Lana is not stupid, and if Clark wants a real relationship then he is going to have to be honest with her . </P> <P>--Kristin Kreuk on Lana's relationship with Lex . </P> <P> The beginning of season five saw, for the first time, Clark and Lana in a happy relationship together, one that was void of dishonesty and secrets . The return of Clark's powers in "Hidden", as well as the secrets and lies that accompany them, caused stress on their relationship . In the series' 100th episode, Clark finally took a chance and told Lana the truth . When it resulted, indirectly, in her death and he was allowed to live the day over again Clark chose not to tell her his secret . In "Hypnotic", in an effort to stop hurting Lana emotionally, Clark told her that he no longer loved her . This drove Lana into Lex's arms . Writer Darren Swimmer explains that this was not something that just happened in the series, but something that had been hinted at for many seasons . Swimmer believes that Lana started dating Lex as a way of making Clark mad, but the relationship "turned into much more". Kreuk contends that Lana went to Lex because "she knows she will never really love him ." Kreuk believes that Lana's relationship with the men in her life has been motivated by a desire to fill a void in her life that was left after her parents were killed . This need to fill that emptiness was fulfilled in "Void", when Lana took a drug to induce death so that she could see her parents in the afterlife . Upon meeting her parents, Kreuk believes that Lana realized that she no longer needed someone else to fill that hole in her . Kreuk sees this filled void as the reason why Lana would gravitate toward Lex . Although she did not truly love Lex, Kreuk argues that Lex was not a rebound guy and that Lana did have feelings for him ." </P> <P> Even though Lana eventually marries Lex in season six, Al Gough argues that Lana still loved Clark and Clark still loved her . The only reason Lana was with Lex was because Clark forced her in that direction and she ended up getting in over her head . By contrast, writer Caroline Dries feels that Lana did love Lex, and that she did not make any hasty decisions when she agreed to marry him . Dries believes that the progression of the show demonstrates that Lex earned Lana's love . To answer viewers that hated to see Lana marry Lex, Dries contends that as viewers we are seeing all of Lex, including how evil he truly is, while Lana only sees the portion of Lex that appears good . </P>
