Now Apophis has revealed himself, he promises the prisoners to overturn Sokar, which requires extracting an irresistibly valuable secret, to which end he drugs Sam with the truth serum 'blood of Sokar' and implants a memory device plus the drug to torture Jack in the persona of his dead kid son and Daniel for the location of his Harsesis son; Martouf's love for Jolinar makes him betray the Tok'ra are on planet Etnac- a convincing lie, so Apophis's plan to earn Sokar's gratitude and then kill him when rewarded with the lordship of Netu is on a shaky basis... Teal'c must help the Tok'ra Aldwin prepare a nuclear weapon to explode the whole moon, as last chance to eliminate Sokar when his ship arrives, but decides to rescue SG-1 instead by flying in the path of the rings device to Sokar's ship...

Did You Know?


In the previous episode, "Jolinar's Memories", Martouf puts the memory device on Sam behind her ear so that the Go'uld won't see it. When Apophis completely activates the device, it is behind her ear. However, when the Jaff'a guards throw her back in the cell with the rest of the team plus Martouf and her father, the imprint from the device is seen, not behind her ear, but on her temple.
