Tapping sat down with Robert C. Cooper at the beginning of "Stargate SG-1"'s season 7 to discuss Carter's struggle with her demons and her life choices in regards to work and family. The events of "Grace" are left open for interpretation, both for the audience and the actors. Grace could be Sam's child within, her hopes and dreams for having a child, the child Sam left behind when she started her career as an astrophysicist, or Carter's potential future with a family. "Chimera" is an offshoot of what happened in "Grace", and the writers were trying to "dispel the black widow curse that Carter has, and also to open her up for more experiences and to flesh her out just a little bit more as a human being". Tapping felt out of her element doing these two episodes, as the flirty side of the character had not really been explored in the show until then. Also, Pete Shanahan does not die, which confuses Carter. According to Tapping, Carter is oblivious what lengths Shanahan is going (stalking, background checks) to find out more about her classified life, although the character is finally free to talk about her life at the end of episode.
