PRODUCTION "There are obviously defining moments for each of our characters. You know, I think very early on in the [series] in 'Singularity,' with the elevator and the little girl -- is [Carter] gonna go to get Cassie, or she going to go back up in the elevator. That was a turning-point, I think, for the character." (Actress Amanda Tapping, in an interview with GateWorld)
