To hear Summer Glau tell it, seeing Cameron get blown up in the Season 1 finale of Terminator: The Sarah Connor Chronicles never had her worrying about paying the next month's rent.

"I had an idea of what was going to happen in the next episode," she told me here on the set of the Fox series, "so I wasn't too upset about it." But as the cast grows and important characters become somewhat expendable - a major death is promised in the first few episodes of the new season - she allows, "I have a healthy respect for being on the show!"

All told, Glau says T:SCC is "bigger" now that it's back (tonight at 8 pm/ET), saying, "I'm very proud of the work we've done so far."

Also in this video: Glau reveals how she stays "really fit" for her role (at the 2:00 mark), shares her admiration for Lena Headey (2:40), and talks of getting teased by her boyfriend (3:50). - Matt Mitovich
