Subversion

S1 E18: Dr. Rush (Robert Carlyle) has a disturbing dream in which he is back on Earth, divulging sensitive information at a covert meeting of the Lucian Alliance. But, strangely, he does so as Colonel Telford (Lou Diamond Phillips). He confides this unsettling dream to Colonel Young (Louis Ferreira) who wonders if there may have been some residual memory overlap during the doctor’s switch with Telford two days before. Suspecting that Telford may be a spy for the Alliance, Rush convinces Young to let him trade places with the Colonel again. Using the communications stones Rush returns to Earth hoping to find some way to confirm his hunch. Meanwhile, Young has a plan of his own, but will need the assistance of General Jack O’Neil (Richard Dean Anderson) and Dr. Daniel Jackson (Michael Shanks).
