 With a rank of lieutenant, Sally is the security officer and second-in-command.She has been called Dick's sister, but was sometimes introduced as Tommy's sister earlier in the series, and, on one occasion, claimed to be his mother, although never Dick's daughter and certainly not his spouse; failure to clarify the exact relationship between Tommy, Harry, and Sally led to humorous confusion whenever either Harry or Sally attempted to act as Tommy's guardian.Sally was chosen to be the woman because she apparently lost some sort of contest and was not too thrilled about it; while the alien species is described as asexual, Sally seems to have a harder time trying to figure out womanhood than the others do manhood.
