This is an excerpt from the interview:
Zap2it: What have you learned about Orwell's background so far?
Summer Glau: Well, there are things I know and things I've made up in my own mind to play the role. What I know is she's a blogger; she created her own site as a vehicle to speak the truth to the people in Palm City because she knows what's causing the corruption. ... She's been on her own since she was 12 years old, and from my own perspective, something had to happen to this girl to make her give up her identity and go out on her own, to have no one in her life. ... So I know that -- but anything else from there is my own invention. What we're shooting right now is episodes 7 and 8, and there's a huge clue into her backstory, but they won't tell me what it is. So I've been playing it from my own perspective.
Zap2It: It sounds like her story isn't that different from Vince's -- she's just been at it longer.
Summer Glau: What's really cool about their dynamic is they met up and joined forces because they want the same thing, but the way they go about getting it is different. She's connected to him in a way -- she hasn't let anyone else in, and it's very hard for her to relinquish control. It's like the dynamic between a man and a woman: She feels like he's not listening, and he feels like she's bossing him. So there's a back-and-forth between them. It's a power struggle between a man and a woman, but not like in a traditional relationship.
Zap2It: Do they see that they can help each other can help accomplish their goals?
Summer Glau: They need each other. They don't like to say it -- I can't speak for David and his portrayal of Vince, but my portrayal of Orwell is that she finally feels like she's not alone. She's been doing this for so many years by herself, and to finally meet someone who's standing up for what she believes in changes her life.
Zap2It: It almost sounds like you're describing the start of a romance.
Summer Glau: [Smiles] Again, from my perspective, it would be impossible for Orwell to be in this situation with him every day and not have dangerous feelings and thoughts. His motive is to get home to his family and be with his wife and son, but for her, I think it's a little bit more complicated.
