"Past and Present" is the eleventh episode of the third season of Stargate SG-1.


SG-1 arrives on the planet Vyus and finds the inhabitants have all lost their memories after a disaster they refer to as the Vorlix. After the team begins investigating the records from prior to the Vorlix, they soon discover that the culprit is someone they've had dealings with in the past.



The planet Vyus.

SG-1 arrives through a Stargate in an alien storage facility. They are met by two locals, a man, Orner, and a woman, Mayris, who are amazed that SG-1 has memories which extend back to "before the Vorlix." It seems the entire population of the planet is suffering from some form of amnesia and have no recollection prior to a date "at least a year ago." Additionally, there are no children or "elders" although they have pictures of the "elders."

Vyan woman

Ke'ra treats a Vyan woman.

Orner takes SG-1 to meet an important member of the "Transitional Government" named Ke'ra, who shows them the main library and explains that their society is unstable and badly compromised because of the Vorlix. When Ke'ra discovers they have traveled via the Stargate she produces a notebook made by a scientist before the Vorlix which mentions a "visitor" who came to the planet by the same means. The visitor was "something of an apothecary" and was called "Linea" (see "Prisoners"). SG-1 suspects that Linea, nicknamed "the Destroyer of Worlds", caused the Vorlix, and that they bear some responsibility.

Ke'ra, Orner, and Mayris return to Stargate Command so that Dr. Janet Fraiser can study the problem. She determines that the catastrophic event was related to an insecticide called "Dargol," which had built up in the planet's food chain and prevented conception in the human population, which explains the lack of children. Linea had discovered a derivative of Dargol that had the potential to prevent aging, and/or restore youth—the elders are not missing because the young people left are the elders. Amnesia was an unintended side effect.


Ke'ra and Dr. Daniel Jackson.

Their suspicions aroused, the SGC runs a DNA test on Ke'ra, comparing it with DNA taken from Linea. The two samples match, confirming they are the same person. However, Dr. Frasier is unable to synthesize an antidote without Ke'ra's expertise. Reasoning that Ke'ra without her memories isn't really the same person as Linea, Major General George S. Hammond allows Ke'ra to continue assisting Frasier.

Having suspected her true identity, Ke'ra steals a small amount of the antidote and regains her memories. Horrified by the memories and heartless personality she has thus released, Ke'ra attempts to commit suicide. Dr. Daniel Jackson, who has been steadily falling in love with Ke'ra, finds her and stops her in time, suggesting a different way to destroy Linea. Ke'ra takes another dose of the Dargol derivative, causing her to lose her memories again. The Vyans agree to offer the new Ke'ra a home on their planet, and a new life.

Notable quotes[]

(Upon arriving at the alien storage facility)
O'Neill: Anybody gets the feeling these folks don't do a lot of traveling?

Orner: Where did you come from? How'd you get in here?
O'Neill: Door was open. Is there anyone around here who might be considered... in charge?
Orner: Me. Show me your papers.
Jackson: We don't have any papers. We're travelers. We've come to meet you.
Orner: To meet me?
Layale: Not you!
Jackson: Actually I meant your people.

Orner: Who would give you a name like Teal'c?
Teal'c: It was given by my father. It means strength.
Layale: You remember your father?
Teal'c: For as long as I draw breath.
Orner: Then you could have not been here at the time of the Vorlix.
Jackson: Vorlix? That doesn't ring a bell.
Layale: It was the day that all we know of ourselves was taken away.
Orner: We can only remember the days since the Vorlix. Before that, nothing.

Ke'ra: There are still so many questions. Why are there no images of children Where have our elders gone? Through your Stargate, perhaps.
Jackson: Well, it's possible that your people foresaw a disaster and sent the most helpless to safety.
Ke'ra: No, Daniel. Whatever happened happened quickly, without warning.
Jackson: How do you know that? (slowly realizing) Because, if you saw disaster coming, you would have left yourselves a note? Sort of a... to whom it may concern?

Carter: What can you tell us about her?
Ke'ra: That she was somewhat of an apothecary. And that she did not survive the Vorlix.
O'Neill: How do you know that?
Ke'ra: The bodies of an elder woman and man were discovered some days later in a building destroyed by explosion. The only remains of our elders we have found. We deduced the male must have been Dr. Zervis. And the female matches what little description he gave in his notes of the visitor.
Teal'c: What is the name of this elder woman?
Ke'ra: It is mentioned... here, yes. She calls herself Linea.

O'Neill: I was just thinking about amnesia. Doesn't quite track with Linea's nickname.
Teal'c: Destroyer of Worlds.
O'Neill: Yeah. That one.
Carter: Well actually in a sick way it sort of does. I mean Ke'ra said herself that their society was on the verge of collapse despite their efforts. This world was in trouble, sir.
Teal'c: Perhaps Linea was experimenting with other ways in which to destroy worlds.
O'Neill: Variety being the spice of life and all.

Jackson: A question. Who would you trust with your life more than anyone in the world? Don't worry, I won't be offended if you don't pick me. Could it be Teal'c?
O'Neill: Sure.
Jackson: Teal'c, just refresh my memory. What was your previous occupation?
Teal'c: I was First Prime of Apophis.
Jackson: Right. Did a few nasty things back then?
O'Neill: We see the point you're trying to make.
Jackson: (referring to Linea) No, you don't. She is not the same person.

Ke'ra: There's a part of me that cares for you, Daniel, more than I've cared for anyone I've ever known.  But there is this other part of me that would gladly watch you die!

Ke'ra: There are two people inside of me, and one of them is a monster. In time, she will win.
Jackson: You won't hurt me, because there's another way, Ke'ra.
Ke'ra: (screaming) I'm not her!
Jackson: No, you're not. But you can be her again. You can forget. All you have to do is forget...


Main Characters

Guest Stars


  • Despite this episode being a sequel to "Prisoners", no "Previously on Stargate SG-1" is shown. This was done so the surprise of Ke'ra's true identity was not spoiled.
  • Teal'c states that his name means "strength" and was given to him by his father Ronac.
  • Vyus is the first planet shown to be in the Industrial Age of development. Most planets have been far below Earth's level of development with a handful being far more advanced.


  • At the beginning of the episode we see and hear the Stargate dialing, but the chevron ring does not move.
  • In the first scene, Major Samantha Carter removes the cloth cover from the Dial Home Device to the point that the center globe is visible. A few seconds later, the red globe is covered even though no one has touched the cloth.
  • Ke'ra says that industry on Vyus has come to a standstill, but all of the outdoor shots show factories working steadily and spewing out smoke.
