"So, what exactly will we see after this eclipse begins?" "It is black and it is a hole." "Well, it might be a... black hole." " Let me put that a different way." " No, you're right." "You can't actually see it." "Not the singularity itself." "It's so massive, not even light can escape it." "But during the totality phase of the eclipse, we should be able to see matter spiralling towards it." "Actually, it's called the accretion disc." "I can see why the local population would be afraid of it..." "What did you just say?" "It's just an astronomical term." "Did you think the colonel had a telescope on his roof just to look at the neighbours?" "Not initially." "Someone from SG-7 should have been here to greet us." "They should be prepping the telescope for the big show." "Oh, God!" "All right, MOPP 4." "Daniel, you and Teal'c check the village." "See why no one's missed this guy, where everyone else is." "We've got the observatory." "All right, move out." "Where is everyone?" " Found 'em." " Oh my God." "Jack!" "Jack!" "They're all dead." "Everyone." "This complex has been decontaminated." " How many dead?" " We estimate about a thousand." "Why didn't they send a message?" " We don't know." " Looks like it happened very quickly." "There may still be survivors." "Shouldn't we look for them?" "Not until I examine you." "We'll use the barracks room." "Colonel, you touched one of the victims without gloves?" " Yeah, but I washed my hands right away." " No." "You are first." "Allergies, right?" " Right?" " Right." "We're supposed to tag the bodies we find with these." " They knew this would happen." " The indigenous people?" "They told me three months ago that with the darkness would come the apocalypse." "It was part of their mythology." "We said "It's just an eclipse and there's nothing to worry about."" "Hello?" "It's OK, you can come out." "I know I must look pretty scary in this mask, but I'm not gonna hurt you." "Colonel, there's someone in the bushes and they won't come out." "Show 'em your face." "Try to look friendly." "We will not hurt you." "Please come out." "Take my hand." "It is OK." "It's OK." "Don't worry." "Everything's gonna be fine." "Can you hear me?" "Very brave." " Can I take this mask off?" " I think it'd be OK." "Looks like we're dealing with a bacterial infection." "Just don't get too close." "There." "That's better, huh?" "You feel like telling me your name now?" "That's OK." "You remember my name?" "Samantha Carter." "But you can call me Sam." "Oh, no." "No, no, honey." "You're not gonna die." "Why don't you just lay down and rest for a while, OK?" "OK." "This can't be." " She's infected, isn't she?" " No, she's not." "What's wrong, then?" "Traces of the element the Stargate is made of are in her blood." " Naqahdah?" " Yeah." "It's possible that's the reason she was able to resist the infection." "Thank you." "Take a look." "Well, I have some bad news." "The samples show the entire area is contaminated." "It's in the water and the ground." "The bacteria doesn't seem to be airborne, but it can survive in varied environments." " Listen, I hate to sound self-centred but..." " Your tests are fine." " What of the girl?" " No sign of infection." "And I did an ultrasound." "She isn't parasitically infested with a Goa'uld." "So she goes back with us." "Doctor, would it be safe for someone to stay a little longer?" "We're safe right now, aren't we?" "Captain?" "Sir, the eclipse happens in less than one day." "This is our only opportunity to photograph the black hole with this telescope." "It could change the course of human history." "I don't want to belittle what happened, but, if we leave, SG-7 and all these people will have died for nothing." "Well, you won't be staying." "I will remain." "I am not at risk." "Yeah, I'll stay too." "Hey, are you OK?" "Don't be afraid." "I'll be holding your hand the whole way." "I know it looks kinda scary, but it's really a lot of fun." "On three." "One, two, three!" "Level one decontamination complete." "Proceed with level two." "Hey, it's OK." "It's OK." "That wasn't so bad, was it?" "Well, here we are." "This is where you're gonna stay for a little while, OK?" "I know it's nothing fancy, but we'll fix it up." "I have to go somewhere for a little while, but I promise you I won't be gone long." "No, I have to go." "But I'll be able to see you the whole time through that camera up there." "See?" "All right, I'll stay for a little while." "She seems to have bonded with Captain Carter." "No wonder she's terrified." "It was not pretty over there." "What happened?" "We counted 1,432 dead." "I... believe we may be indirectly responsible." "How?" "Someone from Earth may have brought a normally harmless bacteria there." "It learned traits from a local organism and mutated into the most deadly infectious strain I've ever encountered." "Are you positive you haven't brought back any of this disease?" "Yes, sir." "In fact, I think we may have brought back the cure." "Doctor?" "Somehow this little girl survived on a completely contaminated planet." "I'm hoping she has a natural immunity that we might use in fighting other serious infections already here on Earth." "Why didn't the telescope team report that this outbreak was going on?" "We don't know." "Don't you want this?" "See, uh... we usually put some stuff on it, like this." "See?" "Mmm!" "That's me, OK?" "You're not alone any more." "This is fun." "Only eight hours to go." "Sweet." "I still do not understand this black hole." "Well, a black hole is this really... big... thing." "It's, um..." "Well, basically, it's a massive... hole... out there." "I see." "And what happens is, everything gets sucked into it." "Even light." "That's why we can't see it." "It just gets... sucked in." "Thank you." "Sure." "Hey." "How are you feeling?" "Listen, I have to go somewhere for a little while." "But you're not gonna be alone." "Daniel will be here the whole time." "Remember Daniel?" "You're very brave, remember?" "I'll be back before you know it." "Please don't go." "You feel like telling me your name?" "Cassandra." "Hi, Cassandra." "I hurt." "Where?" "Sounds good." "No fluid in her lungs." "She described it more like a sharp, stabbing pain." "Her latest blood work shows a marked potassium deficiency." "I have no idea what is causing it, but one of the effects can be arrhythmia." " You're sure she hasn't got the disease?" " Positive." "This is not a bacterial infection." "OK." "Thank you." "All right." "Let's go back to our room." " Thank you." " You are welcome." "What?" "What?" " What is it?" " Get her on the table." " What is it?" " An irregular heartbeat." "She's in arrest." " Code blue in the lab!" " What?" "What do I do?" "Cardiac arrest!" "Potassium deficiency!" "Get me a No. 7 cuffed endotracheal tube!" "Tube's ready." " Tube's in." " Defib." "Stop CPR." "Defib, 60 joules." "Come on, baby, come on." "Clear!" "Let me in, let me in." "I want you to notify the ICU." "I want her potassium levels rechecked, stat." "Wait." "Wait, wait, wait." "Oh my God." " What is it?" " Get me a chest x-ray, stat." "I don't know." "Listen." "Oh my God." " What is it?" " I don't know, but it wasn't there ten hours ago." "I'm inserting the scope." "Image up." " Pulse normal." " I'm advancing the scope." "Pulse is rising." "Adjusting view." "Well, parts of it are definitely organic." "I'm gonna move in closer and try to get a biopsy." "Pulse is now 140." "I'm scraping the harder surfaces for samples." " We have to stop!" " Just a little more." "Removing scope!" "Prepare the paddles!" "Charging!" "Clear!" "Wait!" "Pulse is normal." "This object has the ability to stop her heart in an instant." " Can you remove it?" " Not without killing her." "Dr. Warner got some samples." "I'm hoping the analysis will tell us what this object is." "Thank you, Doctor." " Mom?" " Hey." "You OK?" "I was dreaming about my mom." "You miss your mom very much?" " I'm tired." " Well, then, you should get some rest." "Don't worry." "Everything's gonna be just fine." "And when you get better, I promise you" "I am gonna show you all kinds of wonderful things about this planet." " Promise?" " You bet." " How is she?" " She's fine." "Sleeping." "If you want, I can sit with her tomorrow for a few hours." " No." "We're OK." " OK." "I just..." " I want to do this." " OK." "But I guess what I'm saying is that you don't have to do this alone." "Thanks." "It's showtime." "The systems are online." " The eclipse has reached its totality." " Whoa." "The fatty tissue between the two sides of the object is decaying." "Very slowly, mind you, but still..." "What's the significance?" "I'm about to do an experiment to find out." "One side of the object is made up of a combination of iron and potassium, the other side of the element in the Stargate." "What?" "I assume it's the naqahdah in her blood." "Somehow the object is collecting it." "Potassium can be one of the most volatile alkali metals on Earth." "Combined with even a small amount of naqahdah..." "That doesn't sound very good." "The room you see is in the subbasement floor of this complex." "It's lead-sealed." "Let's see what happens when we put the two objects together." " Where are the samples?" " I'm only using microscopic particles." "The reading's off the scale for radiation." " Are we safe?" " Yeah." "But we have a big problem." "If two microscopic particles caused that..." "The object inside Cassandra could cause a nuclear reaction a million times bigger." " What is that?" " A star, perhaps." "Hit the zoom." "Nah, that's way too close to be a star." "Pull back." "What the hell is that?" "It is a Goa'uld attack vessel." "It's a setup." "It has to be." "The Goa'ulds wiped out every last living person on that planet except Cassandra, then made us think that it was our fault." "They knew we wouldn't leave her there." "They knew we would bring her back here." "They used their technology to put that thing inside of her." "They had us help them create the device after she came through the Stargate so we didn't detect it until it was too late." "We gave her iron supplements." "We may have turned the device on with electricity when we resuscitated her." " So it's meant to destroy us." " Or this complex." " The threat to the Goa'uld's the Stargate." " They used that girl like a Trojan Horse." " How long do we have?" " One hour and 52 minutes." "You can predict it that accurately?" "The cellular decay of the tissue samples appears to be happening like clockwork." "How could they do this?" "Well, to a Goa'uld, she's not as we see her." "She's a tool." "Her death is a very cheap way to get rid of us." "I know I'm supposed to be detached..." "Who said that?" "Sometimes I forget you're not military." "It is the ship of the Goa'uld Nirrti, an enemy of Apophis." "Now, what the hell is that?" "We must go." "Look, sir, I know this decision isn't easy for you." "In fact, the decision is quite easy." "The consequences are what's difficult." "There has to be another way." "I've been assured there's absolutely no way to remove the object from the girl without killing her." "Therefore we have no choice." "Going by Dr. Fraiser's measurements of the device's atomic decay, we have one hour and 20 minutes left." "The girl should be prepared to go back through the Stargate." " I'll take her, sir." " And SG-4." "I want O'Neill and Teal'c to return with you." "We must get to the Stargate!" "No argument from me!" "This Goa'uld Nirrti, he once sent an emissary of peace to negotiate a treaty concerning a Stargate Apophis had taken control of." "The negotiation was a ploy." "The Stargate was destroyed." "How?" "As soon as he entered the Stargate, there was a massive explosion." "The girl?" "Chevron three encoded." " Chevron four encoded." " Cassandra?" "Take your time." "No hurry." " Chevron five encoded." " What is it?" " She's slipped into a coma." " What?" "!" "Chevron six en..." "What the hell...?" " Close the iris." " We're getting an SG-1 remote signal." "Get the girl away from the gate!" "So the Goa'ulds kept SG-7 from coming back to warn us." "All part of the plan." "So what are we going to do now?" "Teal'c, Dr. Fraiser says this device inside the girl is on some sort of timer." "You're sure it will go off if we send her through the Stargate?" "We should not attempt it." "The Earth gate is what the Goa'uld wants to destroy." "Cassandra deteriorated when she got near the Stargate." "I can't risk the security of this mountain." "We'll have to take her somewhere else." " What about the disused nuclear facility..." " Right." "It's just 20 minutes from here." "This is Major General Hammond." "Get me the Secretary of Defense immediately." "It's a matter of life and death." " I can take her from here now, Captain." " No, sir, it's OK." "This elevator goes down 30 floors through solid rock." "Takes three minutes to get to the bottom." "You have four minutes to start back up." "Where are we going?" "Please, go back to sleep." "I'm not tired any more." "Are you crying?" "Sit down here and rest for a while, OK?" "I have to go." "You promised you'd never leave me alone." "I'll come back, OK?" "I'll be back." "You're very brave, remember?" "I'm very brave." "I have to close the door." "Sam?" "Sam?" "Jack, she's going back down." "The hell she is." "Captain Carter?" "Captain Carter." "Sam, do you read me?" "Colonel, I'm staying." " Negative." " Colonel, she's awake." "Oh, God." "Captain Carter?" "I'm ordering you to get back up here right now." "Right now!" " Are we going to die?" " No." "We are not gonna die." "All right, why don't you guys clear out?" "Right." "We're both very brave." " I love you." " I love you too." "All right." "Here we go." " I don't feel anything." " We could've been wrong about the time." "We could've been wrong about what would happen." "Captain Carter?" "Can you hear me?" "Sam, can you hear me?" "We're OK." "Nothing happened." "Cassandra's fine." "I'm fine." "It didn't happen." "I just..." "I couldn't leave her, sir." "How did you know, Captain?" "She first slipped into the coma when we brought her close to the Stargate." "As soon as we got her far enough away from the Stargate, she woke up." "And I... knew." "You knew?" "You're gettin' a little heavy for this." "Cassandra!" "Hey, there he is." " What's that?" " We have a rule here on Earth." "Every kid has got to have a dog." "This is a dog." "And he's yours." "So, how sure were you, really?" "I can't explain it, Daniel." "I just knew." "A mother's instinct, perhaps." "Subtle, but no." "Dr. Fraiser's gonna take her until we can find qualified parents." "By "qualified" you mean ones with the right security clearance." "I wouldn't be surprised if Dr. Fraiser wants to keep her for herself." "As long as Cassandra's happy." "She appears to be." "I wasn't at ease until I knew the object was shrinking and being reabsorbed into her system." "Hey!" "Hey, Samantha." "See my new dog?" "Wow!" "Your new dog?" "It's an Earth rule: every kid has to have one." "But I don't mind." "Why don't I take the dog for a little walk?" "Come here." "Teal'c?" "You know anything about dogs?" "Nothing." "When you find me a new home, will you come and visit me?" "You betcha." "All the time." " That is, when you're on Earth." " Right." " Now, about that, Cassandra." " I know." "The Stargate is a secret, and I was born in a place called..." " Toronto?" " Right." "What are those?" "Ah." "Those are swings." "We never had any of those... in Toronto." " They look like fun." " They are." "Come on."
