She's here! Jenna Dewan-Tatum's Lucy Lane has arrived on "Supergirl," and that's about to make things very complicated for Kara. During an interview with TVLine, Dewan-Tatum opened up on where Lucy and Jimmy Olsen now stand as well as her character's budding friendship with Kara.

Due to this weekend's terrorist attacks in Paris, CBS has rearranged "Supergirl's" episode order so that "How Does She Do It?" -- where Kara defends National City from a series of bombings -- has been dropped from the schedule, at least for now. "Livewire," which finds a volatile CatCo employee transforming into the villainous Livewire, will run tonight in its place. As last week's episode left off with Lucy arriving in National City, an update is in order: by "Livewire," Lucy and Jimmy (Mehcad Brooks) will be back together.

"There's a lot of unfinished business [between James and Lucy]," Dewan-Tatum explained. "There's a lot of unspoken feelings. Her motivation, when she comes back, is to right her own wrongs. She didn't end things well with him... and she knows she made a mistake, so she goes to get him back. I found that really empowering as a woman."

However, Lucy didn't show up in National City just to thwart Kara's affections for Jimmy. Instead, Lucy will develop a friendship with Kara. "[Lucy is] really sweet to her, and she says, 'I want to be your friend.' There's a warmth to her that's really hard to fight," Dewan-Tatum shared. "There's an inherent friendship between them that Kara can't deny."

"What I love is that [the writers] are really about making the James/Kara/Lucy triangle unexpected," she added. "I'm not coming into town to play this bitchy, icy woman that just wants to ruin the relationship that everyone wants to be together. I hope people will understand and get invested in this relationship, rather than [seeing me as] just the foil for the two of them. It takes on a life of its own, which is also really empowering."

"Supergirl" airs Mondays at 8 pm EST on CBS. Developed by producers Greg Berlanti, Ali Adler and Andrew Kreisberg, the series stars Melissa Benoist, Calista Flockhart, David Harewood and Chyler Leigh.
