This week on the CW's Smallville (Thursdays at 8 pm/ET), Lana Lang (played by Kristen Kreuk) walks back into Clark's life, and at a most inopportune time — at least as far as Lois is concerned. "[Lois and Clark] are both discovering how and what they feel," Erica Durance previews in this video. "There is a moment when you think that they may actually admit that to each other... and then Lana comes back."
Ms. Lang, of course, is not some everyday high-school flame to be casually dismissed. As Durance notes, "The writers did a lovely job of creating this amazing first love relationship for Clark... and you can't take that away. What I worked really hard with the writers to portray is that Lois is sensitive to that."
So even though "Lois is a fighter... she realizes that sometimes you need to be patient," Durance says. The actress then adds, "We all know [Clark and Lois] end up together, but the joy is watching the journey. The more selfless Lois is with her love for Clark, the more she'll deserve him."
