  • Episode Description
  • SG-1 returns from a mission, and needs to report to the infirmary to see if they brought back any illnesses. Meanwhile they hear there's been a chemical spill somewhere in the complex. Once in the infirmary, every team member needs a precautionary injection, but Dr. Fraiser injects them with a sedative, rendering them unconscious. Teal'c's symbiote protects him though - he wakes up and sees General Hammond and Fraiser in a conversation with a few unknown aliens. Teal'c escapes and manages to wake up Sam. Sam makes her way out of the complex unseen, while Teal'c distracts the enemy. Once outside, Sam calls Colonel Maybourne, which she meets in a cafeteria. He is accompanied by Jack and Daniel, who explain Sam that she has been exposed to the chemical spill's gas and has been hallucinating since. Has she really, or are there indeed aliens impersonating everyone in the SGC?moreless

  • Trivia & Quotes
  • Quotes (11)

    • Maybourne: Major, a chemical spill causing paranoid delusion is more plausible to me than aliens taking over the SGC. Sam: My God. You don't think I can tell the difference between the two? What was I thinking?

    • (attempting to rescue Teal'c by pretending to the guards to be an alien) Jack: (monotone voice) I have come for the bald prisoner. (the guards open the door and Jack steps inside) Jack: (to Teal'c) You will come with me. Teal'c: I will submit to no further experiments. Jack: Oh, but you will...

    • Sam: They self-destructed. Teal'c: Their destruction appears to be complete. Sam: That's a lot of damage Jack: Coat of paint... a little touch up. It'll be fine.

    • Jack: How is a needle in my butt gonna get water out of my ears? Fraiser: It isn't. Come on sir, you know this is standard procedure. Jack: We should rethink this procedure.

    • Daniel: The remnants of a temple we discovered led me to believe we'd found Kheb. The planet Sha're told me about. Teal'c: However, there was no sign of Amaunet's Harsesis child. Jack: (shouting) Just rain. Much rain. Wind, lightning, hail. Did I mention the rain, sir?

    Notes (3)

    • Alex Zahara and Dion Johnstone also appear in "Beast of Burden" and would again be reunited in "Metamorphosis" They have both played eight different characters on Stargate SG-1.

    • The room in Level 23 that all of the people who have been replicated by the aliens was actually a redressed version of the gate room! Look at the blast door behind all of the people there and it reads C 3L and the blast door to the left, it reads C-2 same as the gate room!

    Trivia (4)

    • Trivia: After this episode, all the GDO codes are changed and the SGC will now do screenings in case of the aliens returning.

    • Trivia: P3X-118 is locked-out of the dialing sequence.

    • After Dr. Fraiser gives Sam the needle and she passes out, you can clearly see the still-full syringe in Dr. Fraiser's hand.

    • The man that Teal'c shot with the zat gun who shot him died, yet his hologram did not deactivate as it happened with the alien impersonating Jack when it died. He was an alien as he said "Alert General Hammond" when he checked the unconscious guard in the elevator for the mimic device so this shows that he was an alien.
