{142}{191}(Stargate alarm) {290}{351}Chevron six encoded. {354}{475}- Glad you could make it, Colonel.|- Wouldn't miss it, sir. This is the best bit. {584}{643}Chevron seven locked. {757}{810}Proceeding with MALP transit. {1033}{1090}(male technician) MALP en route. {1092}{1153}You look tense. {1155}{1219}No, I'd say anxious. {1236}{1297}I am neither tense nor anxious. {1319}{1374}Perhaps concerned. {1377}{1411}Why? {1413}{1499}The address of this planet came|from the repository of the Ancients. {1501}{1560}Receiving MALP telemetry. {1726}{1825}Nothing I can see resembles|anything we know about the Ancients. {1827}{1888}Architecture, technology, writing. {1890}{1966}Maybe it came to this planet|after the Ancients left it. {1968}{2019}Teal'c, do you recognise any of this? {2021}{2120}- I do not, General Hammond.|- Nope. Neither do l. {2191}{2230}I'm just saying. {2347}{2416}- What's it doing?|- Flying, sir. {2418}{2489}- MALPs can't fly.|- Apparently they can. {2545}{2643}- Shouldn't there be a memo on this?|- I do not believe we are still in control. {2645}{2725}Run a systems diagnostic on the MALP. {2876}{2940}- It's stopped transmitting.|- Negative, sir. {2942}{3014}We have a strong signal.|We should be receiving video. {3019}{3080}Uh, Major, you should take a look at this. {3108}{3211}Sir, very high frequency oscillations are|being transmitted on a feedback loop. {3213}{3270}- They may be trying to communicate.|- "They"? {3273}{3320}Well, whoever "they" are. {3326}{3381}- Exactly.|- What? {3385}{3483}Sir, I recommend we disengage|the Stargate and analyse this data. {3489}{3542}Agreed. Terminate the link. {3590}{3660}Whoa! We got an EM spike!|The system is overloading. {3662}{3696}- Shut down.|- I can't get in. {3698}{3784}- Try override!|- Control systems are locked out! Argh! {3961}{4014}The computer's|no longer under our control. {4016}{4090}- Emergency disconnect, sir?|- Do it! {4142}{4210}- Major, are you OK?|- Yes, sir. {6397}{6454}Let's get him to the infirmary. {6519}{6586}He's got first- and|second-degree burns, sir. {6588}{6651}- I'd like to run some more tests.|- Very well. {6721}{6832}The Stargate control systems|and their redundancies are inoperative. {6834}{6901}The circuitry in these terminals is fused. {6903}{6972}- Any idea what that was?|- None, sir. {6974}{7058}The secondary systems are running,|but it was one hell of an EM spike. {7061}{7125}I'd like to run a diagnostic|on the main computer. {7127}{7201}- Yeah. After I treat this hand.|- As soon as l... {7203}{7264}- It is a very bad burn, Sam.|- Five minutes. {7267}{7341}- Now!|- Do as the doctor says. {7343}{7378}Yes, sir. {7380}{7466}Thank you, Colonel.|You, Daniel and Teal'c are next. {7469}{7518}- What? I'm fine.|- What? We're fine. {7524}{7569}I would like to be the judge of that. {7572}{7631}Some form of energy|came through the Stargate. {7633}{7760}It's only prudent to make sure there's|no physiological effects to you all. ASAP? {7834}{7933}- Who put her in charge?|- The US Air Force. {7945}{8050}In medical matters, Dr Fraiser|may overrule those of any rank. {8161}{8226}I'm not gettin' all my memos. {8375}{8475}Well, by the looks of the control room,|I'd say you're both very lucky. {8492}{8549}I guess it could have been worse. {8563}{8628}I'd like to know what it was trying to do. {8630}{8730}Unfortunately, our best diagnostic tool|for figuring that out was trashed. {8732}{8801}- You're all done here.|- Thanks. {8935}{9052}- Reporting as requested.|- Thanks, Teal'c. Just have a seat, please. {9369}{9474}Can you freeze it just before it cuts out?|I want a video capture of this hub thing. {9476}{9570}I might be able to cross-reference|the architecture. {9621}{9736}No, I don't think this place is even|remotely connected to Ancient Earth. {9738}{9783}(typing) {9802}{9899}(Carter) There. This is the start of|the high-frequency oscillations. {9901}{10003}They began seconds after we lost video|and started to multiply exponentially. {10005}{10128}Then the oscillations fused our equipment|and made it impossible to measure them. {10131}{10267}Now, if I isolate the smaller, more detailed|signal and expand the time line... {10350}{10422}There. It's a waveform of some kind. {10425}{10490}- Alien signal.|- Piggybacked on the MALP telemetry. {10492}{10590}That must be how it came back|through an outgoing wormhole. {10592}{10694}I can't analyse it until I get the computers|back up. My hands are tied. {10696}{10774}- There are other computers.|- Not that I can access. {10777}{10851}General Hammond's|put the SGC under quarantine. {11223}{11311}- So information was accessed?|- Apparently. {11314}{11348}Why? By what? {11350}{11436}We don't know, sir. But it branched out|through very specific areas: {11439}{11525}..network and language software,|system and application software. {11527}{11619}- Learning to read, learning to talk.|- And knowledge of our systems. {11622}{11691}You're saying something|was inside our computers? {11693}{11750}We're just guessing at this point, but... {11752}{11865}Whatever it was, we interrupted it before|it completed its scan of our computer. {11867}{11949}Did you determine any more|from the MALP transmissions? {11951}{12080}Nothing on or off world resembles|the architecture. It's entirely alien. {12082}{12172}(Carter) We're running a virus scan|and purging the entire mainframe. {12306}{12437}Our file allocation tables were corrupted.|There are sectors we'll never recover. {12439}{12519}I'm maintaining DEFCON 2|and keeping the mountain locked down... {12522}{12624}..until you can tell me with confidence|there'll be no further repercussions. {12626}{12690}- Yes, sir.|- (camera whirs) {13166}{13227}So it's a probe? {13230}{13308}No, it's like a probe.|We actually don't know what to call it. {13311}{13360}Before we were able to cut it off,... {13363}{13468}..a structured EM wave navigated|over half of our computer system. {13481}{13565}- For what reason?|- Well, we sent a probe to their world. {13568}{13677}- So we're calling it a probe?|- Sure. {13679}{13767}We don't know what would have|happened if we hadn't interrupted it. {13769}{13863}- It did an awful lot of damage.|- Perhaps that was the intention. {13865}{13920}Maybe it was intended to be passive,... {13922}{13987}..but was so advanced|that it fused our systems. {13989}{14065}- We really have no way of knowing.|- Now, what is this? {14067}{14176}The high-frequency oscillations we|received, time magnified and scaled. {14183}{14257}Looks like high-amplitude tracings|of an EEG. {14260}{14332}- Like a brain wave?|- Yeah. {14410}{14459}Hello? {14705}{14777}- It's still here.|- What, the probe? {14780}{14839}Well, whatever it is. {15051}{15118}It sustained itself|within our secondary systems... {15120}{15210}..while we were cleaning up|the main computer. {15213}{15266}Do I look fat? {15268}{15337}It's like it wants us to know that it's here. {15533}{15599}Come here often? {15883}{15930}Yeah, all right, that's me. {16627}{16711}Beg your pardon, sir. The dialling|sequencer just went down. {16713}{16791}- Take it off line, Sergeant.|- Yes, sir. {16936}{17014}- It's learning.|- Learning what? {17023}{17109}Uh, about us. Who we are,|what we do here. {17124}{17177}Put a stop to it, Major. {17179}{17281}- Yes, sir.|- We don't even know its intentions. {17283}{17414}Doctor, I can't allow an alien technology|into our computer systems. {17875}{17951}(Hammond) Have we|maintained quarantine? {17954}{18015}(Carter) Yes, sir. We're still isolated. {18022}{18081}I don't want to contaminate|the outside world. {18083}{18173}I want whatever this is|stopped right here, right now. {18228}{18297}I think it likes me. {18415}{18491}From what I can decipher, sir,|it's like a computer program: {18494}{18566}..incredibly invasive,|but as complex as a DNA strand. {18569}{18634}And it's growing.|It's eating more and more memory. {18636}{18700}- Can you remove it?|- This will take a shutdown... {18702}{18759}..of all systems|connected to the mainframe,... {18761}{18826}..followed by a format of all drives. {18828}{18947}Unfortunately, sir, all data not backed up|before this event will be destroyed. {18950}{19055}- But it's the only way to be sure.|- Understood. Do it. {19067}{19122}We'll be out of commission|for a while, sir. {19125}{19228}I've already alerted all offworld teams|to stay put until further notice. {19231}{19261}Yes, sir. {19264}{19350}- Sergeant?|- Stand by for systems power down. {19384}{19435}Powering down. {19627}{19647}Hey! {20429}{20501}- All scans came back clean, sir.|- Thank you, Sergeant. {20503}{20589}We may have only lost data|from the last 24 hours before the event. {20592}{20680}We'll know more when I can access|the SGC archives in the Pentagon. {20683}{20782}I'd like you and Sergeant Siler to|double-check your results before we do. {20784}{20841}Yes, sir. {20843}{20892}Major. {20981}{21007}You're kidding! {21262}{21311}Carter! {21325}{21390}- Emergency lighting?|- In the MALP room, yes, sir. {21392}{21441}A small power-usage anomaly. {21444}{21515}General Hammond|said we should check it out. {21517}{21595}- Forget to change a light bulb, Siler?|- That's not my job, sir. {21598}{21661}Yes, sir. Light bulb. Very amusing. {21966}{22013}- It's warm.|- Fire? {22015}{22093}(Siler) Alarms would be|going off by now, Major. {22096}{22147}It's been welded, from the inside. {22160}{22250}By who? There's been nobody|on this level since the power shutdown. {22252}{22309}Get a torch. {23246}{23291}(whirring) {24267}{24374}- What is it?|- I don't know, sir. {24424}{24543}I think we robbed the alien program|of an environment, so it created one. {24621}{24757}It appears to be sustaining itself from the|electric power from the emergency lights. {24766}{24852}It must have gotten into a MALP,|survived on battery power... {24855}{24978}..and built this... memory mainframe|while we were on emergency power. {24998}{25092}- "Memory mainframe"?|- I know for a fact we wiped out a ton of it. {25109}{25243}This program must be able to reproduce|itself from a fraction of its original size. {25251}{25353}And now it's expanding into|whatever available memory it can find. {25355}{25400}OK! {25415}{25487}General, we're gonna need|some claymores down here. {25490}{25541}I'm on my way. {25544}{25603}You want to blow it up? {25619}{25662}- Yes.|- Why? {25667}{25699}Why?! {25701}{25820}Sir, we've isolated this area. There is|no chance of reinfection of our computer. {25824}{25896}It's obviously fighting to survive. {25909}{25977}So do bacteria! {26178}{26229}It's trying to communicate. {26231}{26276}So do bac... {26279}{26378}Sir, I agree with Daniel.|This is a life form - obviously intelligent. {26380}{26497}We've been in the same position as this|alien entity I don't know how many times. {26499}{26606}On another planet, cut off|from our world, trying to stay alive. {26643}{26696}What in God's name...? {26717}{26847}Well, General, whatever got into our|computers apparently has built a nest. {27111}{27168}- Overnight?|- According to the security log,... {27171}{27261}..there hasn't been any human activity|in the MALP room for 36 hours. {27265}{27392}For the record, sir, I want to blow it|to hell. These folks want to chat with it. {27417}{27536}Are you absolutely certain|it can't reconnect to our computers? {27539}{27590}General? {27620}{27747}It's surviving on an emergency circuit,|so it's isolated from the rest of the base. {27749}{27833}We can kill it just by|severing that connection. {27859}{27953}- How do you intend to proceed?|- Well, sir, it's provided an interface. {27956}{28073}I'd like to try to make contact with it.|If anything goes wrong, we cut the power. {28110}{28161}Very well. {29169}{29272}Maybe it's trying to figure out|why we sent a probe to its world. {29489}{29538}Major Carter? {29733}{29778}Carter! {29875}{29936}Start an EKG and EEG. {29961}{30004}OK. On my count. {30007}{30064}Three, two, one. {30389}{30444}We in? {30489}{30538}(flatline beep) {30551}{30608}Charge the paddles 100. {30611}{30666}Take over. {31001}{31058}It's normal sinus rhythm. {31213}{31262}Sir. {31301}{31362}What? What is it? {31365}{31461}These readings match those that infected|the computer in the first place. {31463}{31518}It's inside her. {32006}{32127}These weaker readings are|Major Carter's, these are the entity's. {32129}{32203}How can a computer program|be inside a human brain? {32205}{32277}Sam said it was looking for memory|within which to expand. {32279}{32363}The human brain is capable|of storing terabytes of information. {32366}{32464}- How do you intend to remove it?|- I doubt it's even possible, sir. {32466}{32529}More and more of her brain's|being stimulated. {32531}{32648}It's impossible to tell if her memory's|being suppressed, overwritten or erased. {32650}{32769}General Hammond. I advise that Major|Carter be placed under armed guard. {32771}{32816}What? {32818}{32884}If an alien entity|has somehow invaded her body,... {32886}{32983}..then she is a security risk,|and must be treated as such. {32985}{33024}I agree with Teal'c. {33027}{33136}The entity has fooled us twice.|I'll be damned if I'll let it do it again. {33138}{33210}She's to remain under guard at all times. {33212}{33269}Yes, sir. {33810}{33859}Carter? {33957}{34012}She's conscious. {34264}{34336}Can you talk? {34394}{34480}Colonel, her PET scan|resembles that of a stroke victim. {34547}{34674}Parts of her brain seem very active.|Others seem dormant or suppressed. {34676}{34723}The entity has full motor control. {34725}{34844}However, it might be able to communicate|with a speech synthesiser if I explain it. {34847}{34929}Just concentrate on|getting it out of her, will ya? {34948}{34997}I don't know how, sir. {35073}{35161}What about the Tok'ra or Asgard?|Don't they owe us a favour by now? {35164}{35266}Till this situation is resolved, Colonel,|we're still under quarantine. {35268}{35346}That means from ourallies as well. {35349}{35431}We cannot risk the entity|leaving this facility. {35697}{35748}It used a capacitor from the MALP... {35751}{35825}..to deliver a charge|right through the keyboard, sir. {35827}{35880}- Well, don't touch it.|- Yes, sir. {35882}{36024}- Sam said it was growing. Expanding.|- Perhaps the entity that possessed her... {36026}{36118}..sensed that Major Carter's mind|was a better memory-storage vessel. {36121}{36211}- It was a trap.|- A trap? {36214}{36294}Yep. It was watching us the whole time. {36342}{36441}Uh, so you're saying it knew Sam and I|wanted to make contact with it? {36463}{36493}Yeah. {36496}{36603}The device was created as a delivery|system, in order to invade her body. {36611}{36685}- Yes.|- Basically, what you're saying is that... {36688}{36795}..if we'd just listened to you|in the first place and blown it up... {36797}{36862}No, seriously. Is that what you're saying? {36864}{36921}If we had destroyed the entity,... {36924}{37024}..Major Carter would not|have been adversely affected. {37026}{37069}OK, look. {37071}{37196}I know your first instinct is to protect,|both of you - that's your job - but... {37208}{37310}..no matter what happens,|no matter how this turns out,... {37342}{37430}..Sam wasn't wrong|to try to communicate with it. {38269}{38322}(synthesised voice) O'Neill. {38325}{38374}That's right. {38394}{38451}Go get the doc. {38511}{38566}And you are...? {38629}{38672}I am within. {38763}{38876}- You are O'Neill.|- Yeah. We've established that. {38909}{38966}This one has memory ofyou. {38968}{39033}The "one" you're|talking about is a person. {39035}{39113}Her name is Major Samantha Carter. {39154}{39209}Then... I am Major... {39212}{39271}No. No, you're not. {39367}{39486}We understand that you've taken control|of Major Carter, but you're not her. {39529}{39580}There was no other choice. {39603}{39654}No otherplace to go. {39675}{39741}You wished to terminate. {39743}{39788}Still do. {39838}{39918}But you will not. Not now. {39948}{40005}I have observed. {40047}{40100}You value the life ofone. {40134}{40198}Yes, we do. {40226}{40285}This one is important. {40326}{40381}She is. {40443}{40523}For this reason, this one was chosen. {40549}{40648}You will not terminate this one|in order to destroy me. {40725}{40799}It went into Sam out of self-preservation. {40844}{40949}I cannot be removed from|this mind without terminating. {40970}{41034}You will not terminate this one. {41139}{41203}None ofyou will. {41310}{41369}Therefore I will survive. {41583}{41655}The entity insists Sam's mind is intact,... {41658}{41738}..but I can't detect anything|beyond the barest trace. {41741}{41823}I believe, even if I was|somehow able to remove it,... {41826}{41896}..she would be essentially braindead. {41915}{41962}I see. {41975}{42088}Then why does the entity insist|that Sam's mind is still within? {42090}{42145}It's the only way to keep us from killing it. {42147}{42217}Or it's telling the truth|and we just can't detect it. {42219}{42305}Even if Sam is still in there|somewhere, it won't be for long. {42307}{42438}The entity's influence is still growing,|and there is nothing I can do to stop it. {42440}{42487}What course of action remains? {42490}{42580}Well, it wants to survive,|so... we offer to send it home. {42589}{42677}This alien technology is capable|of travelling back to us... {42679}{42740}..through an outgoing wormhole. {42743}{42823}I won't risk the same thing|happening again. {42825}{42942}I've already ordered that the coordinates|be locked out of the dialling computer. {42945}{43085}Let me talk to it. Maybe we can...|convince it to leave willingly. {43118}{43179}Very well, Dr Jackson. {43181}{43228}Dismissed. {43344}{43376}Jack. {43384}{43423}Sir? {43440}{43532}We may have to make|some difficult choices. {43534}{43622}I know that Major Carter|means a great deal to you. {43638}{43714}She's a very valuable|member of my team, sir. {43727}{43774}Yes, she is. {44585}{44644}My name is Daniel. {44678}{44737}(synthesised voice) I am aware. {44740}{44822}Right.
