“Singularity” is the fifteenth episode of the inaugural season of Stargate SG-1 .


SG-1 arrives on the planet Hanka and learns that everyone, natives and Stargate Command personnel alike, has died from a cryptic disease. They find Cassandra, the lone survivor, and take her back to Earth. They soon learn, though, that she has had a turkey planted inside of her, set to blow in a topic of hours, and removing it is impossible.

Reading: Singularity


SG-1 is leaving Stargate Command through the Stargate, traveling to a planet called Hanka, where SG-7 has established the Douglas Mclean Memorial Observatory, which SG-1 is now visiting in promise of seeing a blacken trap. technically, as Captain Samantha Carter explains, the black hole itself can not be seen ; quite, they intend to watch the matter spinning towards the hole. Dr. Daniel Jackson is surprised when Colonel Jack O’Neill announces that this is called an “ accretion phonograph record ”, and Carter mentions the telescope on the roof of O’Neill ‘s theater as proof that he knows a thing or two about astronomy .
however, after walking through the gate, SG-1 finds that the site on the planet has changed. They cursorily run into the dead soundbox of a native who has been killed, apparently by a disease. After they ‘ve donned protective masks, except for Teal’c, the team immediately begins searching the village and observatory. As Daniel and Teal’c check the village, Jack and Sam check the lookout and find the bodies of SG-7, who are in precisely the like circumstance as the villager they discovered earlier. As Jack and Sam struggle to grasp what ‘s happened, Daniel and Teal’c arrive, with Daniel breaking the newsworthiness that everyone is dead. A while late, Dr. Janet Fraiser explains that the complex has been decontaminated. carter wants to leave the compound and search for any survivors, but Fraiser insists that the team be examined immediately. Because O’Neill touched the beginning body found without gloves, he is the first to be examined. After being examined and released by Fraiser, the team begins searching for and tagging bodies. Daniel begins the setting by talking about what information they had received from the natives three months early when the SGC sent its foremost team to the planet. The natives had said that “ with the darkness would come the apocalypse. ” Daniel appears to believe it was in part the blame of land that the people died – they insisted that it was merely a myth and that the darkness was merely an astrological phenomenon. The submit is dropped when they find their beginning bodies. once Carter tags one, person in the bushes removes the tag. Believing the person is scared by the protective outfits the team is wearing, O’Neill tells Teal’c ( not wearing a protective suit since his symbiote will protect him ) to “ try to look friendly ” and get the survivor to come out from hiding. Teal’c convinces the person to leave the bushes and it is seen that she is good a young girl ( whom Teal’c favors with one of the few smiles he displays in the first season ). The team brings her back to the complex for Fraiser to examine. Carter attempts to communicate with the girl, but she does not respond to anything. Fraiser calls Carter over and informs her that while not infected, the girl has traces of Naquadah in her rake – possibly the rationality she was able to resist the infection. Fraiser briefs the team on the problem – the sphere ‘s water and grind are both contaminate, but none of SG-1 tested positive for the infection. While Carter attempts to convince O’Neill to allow the team to stay and observe the eclipse, the young survivor comes up from behind and hugs her. O’Neill tells Carter she wo n’t be staying, but that he and Teal’c will. Carter returns to Earth with the young daughter, who appears amazed and intimidated by the gate board. She then takes the girlfriend to the board she will be staying in while at the SGC Carter attempts to leave, assuring the girlfriend she will be rear soon but has significant work to do, but the female child does not want her to go, so Carter agrees to stay. Meeting with Major General George S. Hammond and Daniel, Fraiser explains that earth may be “ indirectly responsible ” for the disease. She explains that one of the teams may have brought a harmless bacteria to the satellite, where it then mutated into an infectious and deadly form. Reassuring Hammond that the cipher brought the bacteria back to earth, she explains that they may have brought back the cure, a young daughter who, for whatever reason, survived. She hopes that the daughter may have a natural immunity that could be used to prevent other infections on earth. Carter, who stayed with the female child, appears to have decorated the room during the briefing. Using paints provided by Carter, the daughter illustrates the end all around her. Attempting to convince the girlfriend she is not entirely, Carter paints herself into the photograph ( as a stick figure ). back on Hanka, Teal’c tries to understand what precisely a black fix is. O’Neill attempts to explain, describing it as a “ very big thing, ” or a “ massive hole ” that is “ out there. ” Teal’c simply responds, “ I see. ” O’Neill continues his explanation, describing what the black trap actually does ( “ fair … sucks it all in ” ) ; Teal’c matter-of-factly says, “ Thank you. ” On Earth, after Carter tries to leave the room, the young girl grabs her arm and speaking for the first time, says, “ Please do n’t go. ” Carter then learns the female child ‘s mention : Cassandra. Complaining of pain, Cassandra is taken to Dr. Fraiser, who discovers that the female child has low potassium levels. Cassandra then on the spur of the moment collapses. Fraiser immediately begins trying to help the girlfriend, but while listening to her heart, finds an strange noise. A breast x-ray reveals that something has attached itself to Cassandra. A biopsy reveals that whatever it is appears to be at least partially constituent and has the ability to stop Cassandra ‘s heart. Carter ‘s analysis of the object reveals that one slope is made of iron and potassium, which accounts for Cassandra ‘s low potassium levels, and the early side of Naquadah. She performs an experiment to see what happens when potassium and Naquadah react. The microscopic amounts create an explosion big adequate to destroy the camera on the early side of the room. radiation levels in the room were off the charts.

On Hanka, Teal’c and O’Neill are observing the black fix when they discover a Goa’uld attack vessel ( the first appearance on the appearance of what would late be called a Ha’tak starship ). In a meeting, Daniel and Carter speculate that Cassandra is being used involuntarily as a weapon by the Goa’uld as a entail of destroying at the very least the SGC complex and Stargate. Fraiser besides reveals that the cellular decay leaves them with lone one hour and fifty-two minutes to solve the trouble. While observing the attack vessel, Teal’c sees something leave the attack vessel and insists they must leave for the Stargate. On ground, Hammond has made the decision to send Cassandra back to her home planet to prevent Earth ‘s Stargate and the facility from being destroyed. back on Hanka, Teal’c and O’Neill, who are running from Goa’uld gliders. Teal’c explains to O’Neill that the Goa’uld, Nirrti, had before used negotiations as a gambit to destroy opponents ‘ Stargates. O’Neill realizes the female child is another of Nirrti ‘s attempts to destroy a Stargate. On Earth, while the crew is dialing Hanka, Cassandra once again collapses. Before the final chevron can be encoded, Teal’c completes the dialing succession on Hanka and thereby opens the Earth Stargate, returning to Earth with O’Neill .
adenine soon as they get through, Jack orders Cassandra be taken away from the Stargate. In the Briefing Room, Teal’c believes that if Cassandra goes through the Stargate, the gate will be destroyed because the Earth Stargate is what the Goa’uld want to destroy. The decision is former made to send Cassandra to an abandoned nuclear adeptness although Sam is visibly reluctant at the decision. On the way to the bottom on the nuclear adeptness Cassandra wakes up. She notices that Carter is crying, but Carter is ineffective to explain why. once the thirtieth sub-floor is reached, Carter opens the vault where Cassandra must stay and tells her to “ rest ” there for a while. In tears, Carter explains that she must leave. Cassandra tells Carter she promised never to leave her alone. Carter tells her she is brave, closes the vault, and, still in tears, leaves for the elevator. Once she reaches the 26th floor Carter changes directions and heads back down to Cassandra. Carter declares to O’Neill that she is staying, despite his order to come back up. The time is reached, however Cassandra has not even exploded. Carter explains that she simply “ know ” that Cassandra would not explode. The episode closes with Daniel, Carter, and Teal’c walking through a park with Cassandra. O’Neill approaches, carrying a frump ( a shiba inu ). He explains it is a rule on Earth – every child needs a frump ( Carter smiles upon hearing this “ principle ” ). Carter explains that Fraiser will take care of Cassandra until adopted parents were found, and that the object has been shrinking ever since she was taken away from the gate. Like Cassandra, Teal’c knows nothing of dogs either. ultimately, Cassandra acknowledged that the Stargate is a mystery, and she will tell people that she is from a place called “ Toronto “ .


noteworthy quotes

Jackson : so, what precisely are we going to see after this eclipse begins ? I mean, it is black, and it is a hole …
O’Neill : well, it might be a black trap.
Jackson : Okay. Let me put that a different way.
Carter : No Daniel, you ‘re right, you ca n’t actually see it, not the singularity it ‘s self it ‘s so massive not even light can escape it. But during the entirety phase of the overshadow, we should be able to see matter spiraling towards it.
O’Neill : actually, it ‘s called the accretion phonograph record.
Jackson : Well, I guess it ‘s slowly enough to understand why the local population would be afraid of something like that … (looks at Jack) What did you good say ?
O’Neill : It ‘s just an astronomic terminus.
Carter : You did n’t think the colonel had a telescope on his roof fair to look at the neighbors, did you ?
O’Neill : At least, not initially … Teal’c : I however do not understand this black hole.
O’Neill : well a black trap is … is truly … a big matter. It ‘s uh … basically it ‘s a … massive … hole … o ?
Teal’c : I see …
O’Neill : Ah, and … what happens is, everything gets sucked in to it. even light. That ‘s why we ca n’t see it. It … merely … gets … sucked in …
Teal’c : thank you.
O’Neill : certain. Carter : spirit, Sir, I know this decision is n’t easily for you …
Hammond : In fact, the decision is quite easy. The consequences are what ‘s unmanageable. Cassandra : I know – the Stargate is a mysterious and I was born in a rate called … Toronto ?

O’Neill : We have a rule here on Earth. Every kid has to have a frump .

  • At 2 minutes and 1 second into the episode you can clearly see that Captain Samantha Carter’s Å-symbol on her jacket is upside-down.
  • Shortly after arriving through the Stargate at the beginning, and upon discovering the dead body, Colonel Jack O’Neill says, “Alright, MOPP 4.” This would mean that SG-1 was to assume Mission Oriented Protective Posture 4, which involves the donning of their Gas masks, gloves, overshoes, and chemical protective suits. However, the team only dons their protective masks and gloves, and then proceeds with their mission.
  • While it is rather unnoticeable, and appears to be only a trick of the light, right before SG-1 meets Cassandra (at 5:57 on the DVD version of the episode), one of the dead people’s head moves slightly.
  • As O’Neill and Teal’c return to Earth to ensure that Cassandra is not sent through the gate, the decontamination sprays are not visible as the gate engages. Stock footage of the unaltered gate room is used.
  • As Carter and Dr. Janet Fraiser are applying CPR to Cassandra, Cassandra’s shirt alternates between being closed and open between shots.
  • At the very end of the episode when Dr. Daniel Jackson goes to sit down on the bench, you can see the transmitter to the microphone on his belt. (Approximately 40 minutes 23 seconds on the DVD version of the episode).
  • While Dr. William Warner is using the scope to try and figure out what the object is inside Cassandra, her heartbeat changes drastically. When they cut to the heart monitor, every time it is set to (Adult) when Cassandra is, in fact, 12 years old and would have a children’s setting.
  • In addition, while Frasier is calling out Cassandra’s heart rate, she’s actually looking at the systolic blood pressure.
  • When Warner withdraws the scope, the entire pulse waveform is shown as reverting to normal, even though the graph spans several seconds of time.
  • Teal’c refers to Nirrti as a he, but later episodes show that Nirrti is in fact female. However, this can be attributed to several possible causes: Teal’c may not be aware that Nirrti is female, as Teal’c may simply have never encountered her or heard her referred to as female. Alternatively, Nirrti may have, at one time, had a male host (possibly even during the events of this episode, as Nirrti would not be seen on-screen until two seasons later).
  • When Teal’c and O’Neill return to Earth after escaping from a Goa’uld Death Glider, the thigh holster around Teal’c’s right leg has disappeared.
