He says the last six episodes will answer some questions and ask new ones. “All you try to do is make the best episode you can and hope that people are excited about it,” he said. ” I try to do that every week. The goal is to try to make the best episode on TV every week within the parameters you sort of set up for yourself. I think they are among  the best episodes we’ve done for the two years.”

Some of the issues that will be examined include Cameron’s attiude towards John Connor’s girlfriend, Riley, and how the chip malfunction from the opener of season two last fall has affected her.  “I think if my character’s experiencing anything, it might have been insecurity about whether or not she was capable of doing her best in protecting John anymore, ” Glau says. “She’s really struggling with the insecurity of having a new girl in John’s life, Riley.”

Friedman is also philosophical about the ratings, which have dipped since the move to Friday nights, and sparking internet rumors that cancellation may be coming. “We’ve had the same ratings for two years,” he says. “We really have been kind of bumped along in a flat way for two years. The move from Monday to Friday, the amount we’ve gone down is the amount statistically basically you go down from Monday  to Friday.  It’s not like we dropped down in some sort of abberant way beyond what one does when one moves.”

Summer is proud of the work she has done as Cameron, the Terminator who tries to protect John while he and his family try to stop Skynet, the program that sets off the Terminator apocalypse, from being born. “I really feel priviledged to play a character I think has evolved so aggressively throughout two seasons of television, ” she says. ” I hope that i get a third season so I can keep going. It’s just been wonderful.”

Glau says Cameron has been through a lot that would affect any Terminator, or young woman. “Cameron thought she understood herself. She thought she had an agenda that hasn’t been revealed, and I think when she was damaged things were going on in her mind,” she says.  “She’s learning a lot from people around her, and she’s also having to question herself because she has weaknesses now. She’s having to struggle. She has weaknesses. I think it’s creating road blocks in her goals, and that’s been a much more complicated thing to incorporate in my stategy in playing Cameron. But it’s been really, really fun, too.”

Glau will also be seen in an unlikely place: on a CBS sitcom. She’s play herself in the March 9th episode of The Big Bang Theory, when Leonard, Sheldon and his friends spot her on a train to San Francisco. She admits being in a comedy was quite different from clobbering bad guys.
“I was playing myself, but I was trying to be funny”, she says. “They tried to make me funny. I wanted Josh to come be on set because I was nervous because it’s supposed to be about how I would respond to people who know my work as Cameron. I was concerned about how people might perceive that. It was an honor to work with such talented actors. I haven’t watched every episode of that show, but I think they are some of the most brilliant young comedic actors on TV.”

She adds that comedy is delicate work. “Every word can change whether it’s funny or not, and I didn’t realize that. I had no idea”, she says. “Sometimes they would say, ‘OK, say it going up, say it going down, say it quick, say it slow.’ That’s how specific it was to piece together the scene.”
She was also worried that she’d laugh during taping because she was nervous..” Once we got started I was sweating bullets,” she says, “and I was not laughing. I was serious about doing a good job.” Friedman had to do something else, but got word from the show’s crew that she was funny. She also noted the crew really knew their pop culture references, including her show.

Now, though, it will be back to serious business, as Cameron, Sarah, John and Derek continue the fight against Skynet.

Terminator: The Sarah Connor Chronicles airs Fridays at 8 PM on Fox.
