'Bates Motel' Season 2: First look at Rebecca Creskoff's Christine, Norma's new ally

The relationship between Norma (Vera Farmiga) and Norman Bates (Freddie Highmore) is going to get even more complex as "Bates Motel" enters its second season. Zap2it is debuting a new promo for Season 2 of the A&E drama that shows just how dependent this mother and son duo are on one another.

"I'm really, really excited about the arc for Norma and Norman. I think their relationship definitely escalates. It just gets deeper and more interesting and more twisted," executive producer and writer Kerry Ehrin tells Zap2it. "They're both so co-dependent and they're both so dysfunctional. They need each other so much, and they have to constantly be like a chess game about how much do I have this person on a string."

But beyond the almost obsessive nature of Norma and Norman's relationship in this new promo is the introduction of a new character played by Rebecca Creskoff. Her character, Christine, is a New Yorker who married into White Pine Bay and decides to befriend Norma.

"She's this really interesting character of this sort of transplanted New Yorker," Ehrin explains. "She's there doing community theater just to keep herself from being bored to death. She runs into Norma, and she gets that Norma's sort of interesting and different and takes her under her wing a little bit."

But like with most things in Norma's life, her relationship with Christine won't come easily. By getting more involved into the inner workings of the politics of White Pine Bay, she could find herself in over her head.

"The fun thing is how you never see exactly how it operates," Ehrin says of the people in power in the idyllic town. "You never see exactly who's pulling the strings. Everybody has an agenda. Everybody has people they're beholden to, and everybody has people that they are afraid of. And everybody's trying to walk the line between all those different factions behind the guise of, 'We're just having a normal life.'"

She continues, "The fun of it is not so much about seeing the inner workings of it, it's of Norma trying to navigate her way through this very choppy water where you don't ever know who's on whose side or who knows what or what they know about you. It's kind of building up the mythology of White Pine Bay through that."

Through Christine, viewers will get to meet Norma's new love interest: Michael Vartan's George.

"Michael Vartan is part of a storyline for Norma that is really about Norma getting very close to achieving her dream," Ehrin explains. "She moved to this town with this idea that it was going to be kind of this idyllic existence with her and her son and they'll have a successful motel and they're going to have normalcy."

She adds, "We saw a lot of stuff go awry for them last year. We wanted to give Norma a chance to get close to getting what she wanted. Part of that comes through her introduction to this more upscale, upper echelon faction of the town, White Pine Bay. People who are connected, people who are educated, people who kind of run the local politics. She gets into that a little bit through a woman she meets. Michael Vartan's this woman's brother, and that's how she gets connected with him."

Just don't expect Norma to be able to infiltrate their inner circle with ease. "When you have all these demons and dysfunctions, you're kind of always outside. Even when you're inside, you're outside. So I think it's the story of that," Ehrin teases. "It's the story of destruction and implosion."

"Bates Motel" returns to A&E on March 3 at 9 p.m. ET/PT.
