  • What would have been a great episode is ruined by the ending.

    The concept of Singularity is an interesting one, although some of the pseudo-science they use to back it up is toe-curlingly aweful. Plenty of character development for Captain Carter, and an interesting and slightly unusual threat to Stargate Command in the form of a small girl with ridiculous bomb inside her. The episode builds steadily to its climax, but then, in a move of utter cowardice, chickens out of what should have been the inevitable and powerful ending to the story. The image of Carter weeping uncontrollably is a very strong one, and if she had come out of the lift and then felt the rumble from below, then I think it would have been my favourite episode of the season.

    As it was, the natural flow of the story was blocked, and was instead forced down the path of an incredibly disappointing saccharine happy ending. "On Earth, all children must have a dog." What kind of rubbish is this? It destroys the pathos that the viewers would have experienced if the ending had been done properly, turning a great episode into an at best average one. I hope the original script had the heart-wrenching proper ending that it deserved in it and that the network meddled, because there is no excuse for it otherwise.

    Take an intelligent, beautiful young girl, daring SGC teams and a never-ending succession of off-world settings. Add more than a dash of danger and espionage on planet P8X-987 and you get episode "Singularity." The SGC teams are based deep underground in a mountain complex somewhere in Colorado Springs, Colorado, which now houses the pulse of Stargate operations-a gate room center on level twenty-eight and their cover. In this episode SG-1 tries to uncover why another team and most of the people with the exception of a little girl have been wiped out. Their assignment here combating injustices and the Goa'uld Nirrti in a plot to destroy Earth's Stargate!moreless
  • A vicious virus has killed every person on planet PX8-987 ... except for a little girl.

    After arriving on a planet to observe a black hole, the team finds that everyone has been killed ... except for a little girl.

    We later find that it was a biological attack by the Goa'uld Niirti on the planet and on earth.

    The little girl was given the anti-virus by Niirti, so she could survive the virus, but she was also given a bomb that would detonate as soon as it went through the Stargate a second time ... knowing full well that SG-1 would take her in, once they found her alone on this planet.

    Another episode with character development ... we see Sam's wonderfully caring personality, as she is willing to sacrifice her life, in order to keep company to a little girl on possibly the last seconds of her life.

    We also see Jack's, often hidden by him, knowledge and intellect.moreless
  • Sam gets a personality! Teal'c learns about black holes!

    A good episode that demonstrates that the Goa'uld are truly merciless. The episode also introduces the rather infamous Goa'uld Nirrti, who prefers to use humans as weapons rather than starships. The Sam moments in this episode were nice, but as in many other episodes Jack and Teal'c break it up with their back and forth at the observatory( or rather Jack's back and forth and Teal'c's eyebrow raising lol). It was nice to see an episode other than Hathor(which did nothing for Sam's character) that focuses on Sam, and makes a serious effort to humanize her. Sam was the last of the team to really get her personality sorted out, and I would consider this episode the start of her transition from a somewhat-feminist two dimensional character to a deeper, more comfortable and likable person.moreless
  • This was a good episode to progress Carter's character but fell short of average.

    SG-1 travels to a planet full of corpses including SG-7, only to find a little girl who is seemingly healthy. They take her back to the SGC only to find out she has a ticking time-bomb implanted in her by the Goa'uld to destroy the SGC. However, Carter grows more and more attached to her and when the only option left is to send the girl miles underground, Carter stays with her, not having the heart to leave her there. Emotional episode, great acting by Amanda Tapping as usual. But then ofcourse the miracle happens, sparing Carter and Cassandra. Good Carter episode, but I'm not really that interested with the "save the little girl" plot.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (13)

    • Trivia: This is the episode in which the element of which the Stargate is made and which powers Goa'uld technology, naquadah, is named.

    • Trivia: This is the first episode where Dr. Fraiser goes off world.

    • Trivia: Daniel's allergies are mentioned again in this episode when Daniel sneezes after decontamination, Jack asks if it's his allergies. After this episode they are only mentioned sporadically, in "The Gamekeeper" and "One False Step."

    • As Dr. Frasier resuscitate Cassandra, the close up of her hands performing chest compressions show Cassandra's clothing open, but wider shots immediately before and after this show the clothing closed.

    • After Cassandra has her first "heart attack" you see her in her room. There isn't a heartbeat monitor in her room. Clearly one would be present after something like this.

    • In the scene when Earth is dialing Hanka to send Cassandra back and then Teal'c dials in faster and the Stargate activates, first when you see the Gate before it activates the decontamination thing is there then the gate activates and the vortex comes out and the decon thing isn't there, then after the gate is activated the decon thing is there again.

    • Shortly after SG-1 have been checked out by Dr Frasier, the team are walking along a road, and talking about how they should tag the dead bodies they find. As they walk, two bodies come into view, and the "dead" villager furthest right lifts her head slightly as the team approach.

    • Check Jack's watch when it's counting down until the explosion. At 1 minute left it says 7:41, at 20 secs it says 7:42, at 9 secs it's back to 7:41

    • While on Hanka during the beginning, Captain Carter's "Earth" patch (left shoulder) is upside down.

    • Hanka was called PX8-987 on the sign, but in other episodes, it's called P8X-987.

    • Jack said the elevator goes down 30 floors in the abandoned nuclear facility, but when we see Carter exit the elevator, it stops on level 28 - wouldn't it make more sense to go down all the way?

    • Hanka seems awfully bright during the total solar eclipse.

    • When Teal'c and Jack were running to the Stargate, Teal'c called Nirrti "he" but we find out that Nirrti is a woman in "Fair Game". Typically Goa'uld referred to as the gender of the host body and tend to seek out hosts of the same gender when available.

  • QUOTES (9)

    • Cassandra: I know - the Stargate is a secret and I was born in a place called...Toronto?

    • Jack: (giving Sam a moment by herself) Why don't I take the dog for a little walk. C'mere. Teal'c? You know anything about dogs?
      Teal'c: (deadpan) Nothing.

    • Jack: We have a rule here on Earth. Every kid has to have a dog.

    • Sam: Look, Sir, I know this decision isn't easy for you...
      Hammond: In fact, the decision is quite easy. The consequences are what's difficult.

    • Sam: I know I'm supposed to be detached.
      Daniel: Who said that?
      Sam: Sometimes I forget you're not military.

    • Teal'c: I still do not understand this black hole.
      Jack: Well a black hole really...a big thing. It's uh...basically it's a...massive...hole... ok?
      Teal'c: I see...
      Jack: Ah, and...what happens is, everything gets sucked in to it. Even light. That's why we can't see it. It...just...gets...sucked in...
      Teal'c: Thank you.
      Jack: Sure.

    • Sam: Colonel, there's someone in the bushes and they won't come out.
      Jack: (to Teal'c) Show 'em your face. (Teal'c looks...normal) Try to look friendly.

    • Jack: (talking about a black hole) Actually, it's called the accretion disk.
      Daniel: Well, I guess it's easy enough to understand why the local population would be afraid of something like that... (looks at Jack) What did you just say?
      Jack: It's just an astronomical term.
      Sam: You didn't think the colonel had a telescope on his roof just to look at the neighbors, did you?
      Jack: At least, not initially...

    • Daniel: So, what exactly are we going to see after this eclipse begins? I mean, it is black, and it is a hole...
      Jack: Well, it might be a black hole.
      Daniel: Okay. Let me put that a different way.

  • NOTES (2)


    • Cassandra:
      Cassandra was the most beautiful of the daughters of Priam and Hecuba, the king and queen of Troy. She was given the gift of prophecy by Apollo, who wished to seduce her; when she accepted his gift but refused his sexual advances, he deprived her prophecies of the power to persuade.

      At the end of the Trojan War, Cassandra foresaw the danger posed by the Trojan horse; the people of Troy ignored her warnings and the Greek soldiers hiding inside the horse were able to capture the city. During the sack of Troy, Cassandra was raped by the Locrian (or "lesser") Ajax, and was then given as a war prize to Agamemnon. She returned to Greece with Agamemnon, and tried to warn him of the danger which awaited him there; once again her prophecy was ignored, and both she and Agamemnon were murdered by Clytemnestra and Aegisthus.
