Could there be another incarnation of Joss Whedon's science-fiction western "Firefly" on the horizon? Summer Glau says of course: it's a show that is "never over."

"We're very close," Glau said of the cast during a recent press conference with reporters including Airlock Alpha. "I get to see Nathan [Fillion] the most because he lives the closest, and I still see everyone whenever I can."

Someone she misses a lot is Jewel Staite, who is now a regular on SciFi Channel's "Stargate: Atlantis," thus spends a lot of time in Vancouver, B.C.

"We all had such a strong bond, and that was my first experience," Glau said. "I didn't even know how to stand on my mark. I blocked the camera all the time, I ran into people, and they still treated me like an equal and as part of the family. I think we would all come back if we got the opportunity."

In the meantime, however, Glau has taken on the role of a Terminator in Fox's "Sarah Connor Chronicles." Unlike costars Lena Headey and Thomas Dekker, who reprised roles originally made famous by the likes of Linda Hamilton and Eddie Furlong, Glau got to take on a role created specifically for the new series. But that didn't stop fans from trying to compare her to a certain state governor.

"Lena and Thomas have done an amazing job, and they're both very brave actors," Glau said. "I completely trust their versions of their characters. It was easier for me, but people still ask me about Arnold Schwarzenegger. No one can possibly compare me to him. He was an icon, and I am doing something very different."

Playing the somewhat emotionally and societally detached Cameron, Glau has had to face an evolution of sorts with her robotic character. Some viewers felt that it was inconsistent of her character to be very human when she is first introduced in the pilot, and then suddenly be more machine than anything else as the series has wore on.

"We were experimenting with Cameron quite a bit, and we wanted her to be able to seem to be human, and we especially wanted John to be fooled by her so that he would let her into his life," Glau said. "So in the pilot, I do act very human, and as I go through the series, it appears that I have taken steps back and acting more like the Terminator that I am."

Cameron is trying to develop more of a human perspective, but Glau says she likes the challenge of trying to achieve a real sense of that, not just one that was programmed to fool John in the beginning.

"Once her cover was blown with the Connors, she was able to drop that persona and become who she really is," Glau said.

It's hard to ignore the similarities between her character of Cameron in "Sarah Connor" and River Tam in "Firefly," but these are still two totally different characters, Glau said.

"They're both kind of foreigners in their surroundings," she said. "River was never good at being able to relate to the people around her, and always seemed to be somewhere else in her mind. And Cameron is the same way. She is from a different place, a different time. She is not human, and she doesn't really know how to relate to people that she is living her life with now."

Will she begin to relate with humans enough to love them? You know, like with John Connor?

"The writers are keeping me guessing," Glau said. "I can't tell you, but I know that [a John-Cameron romance] is a possibility, and I think Cameron does love John in her own way. Her entire existence is to protect him. Her entire purpose in life is to keep him safe and to be with him always, and with that she does love him as best as she can."

"Terminator: The Sarah Connor Chronicles" airs Mondays at 9 p.m. ET on Fox.
