Previously on "Stargate SG-1":
First we must rescue Thor. He is a prisoner of the Goa'uld.
I am Anubis.
This device... will be implanted into your brain.
It will form a link between your mind and the ship's computer.
Your knowledge will simply be downloaded into our memory banks.
- O'Neill? - Thor?
I am using the internal communication system to synthesise my voice.
I may be able to rewrite some minor subroutines in the security protocol.
Lord Anubis, the Asgard prisoner is gone.
He will not get far.
- You cannot take me with you. - Why not?
The link between myself and the Goa'uld ship has not been severed.
They managed to remove the device from his brain, but it may be too late.
Apparently he's lapsed into a coma.
Looks like your analysis was right, Sam. It's dead in space but intact.
- Has Anubis done this before? - This is a first.
Must've been crazy around the SGC when it showed up.
You've no idea.
I have a pretty good idea. I used to be an Air Force general, remember?
Are we there yet?
Not yet, sir. Close enough to do some scans.
Scanned anything yet?
- Nothing, sir. - Nothing?
It's in a stable orbit, shields and weapons are down, and it's emitting no EM.
- Still just kinda sittin' there. - Yes, sir.
If they were going to attack Earth, they'd have done it by now.
What are you smiling at?
It's just that it's my first time... in space.
Ah.
We'd only begun to consider space travel. To actually be out here is...
- It's amazing. - Indeed.
Until something goes horribly wrong.
What's our status?
The ship should be just a few hundred kilometres dead ahead.
There.
Ship ahoy-hoy!
That's incredible.
I'm not 100%, but this could be the same ship Anubis used to kidnap Thor.
Now we know why they haven't attacked.
- There's no life signs. - The escape pods have been jettisoned.
The ship has not been damaged in battle.
Power and life supports are functioning normally. There's nobody on board.
Why would they abandon a perfectly good ship?
They wouldn't.
Jack, rather than fly into a cargo bay,
I recommend we use the transport rings until we know what's goin' on.
Yeah.
Boys.
Let Hammond know we'll have something in a couple of hours.
- Jonas, stay with Teal'c. - I don't understand.
I'm sorry. Stay here.
- I'm not going with you? - Not this time.
I've studied every report, everything on Goa'uld...
Because I gave you an order, Jonas.
I always have a reason. I'm not required to explain.
It's a military thing.
Jack.
- What is that? - I can't make it out.
The crew has abandoned ship.
That's good news. We've all been holding our breath down here.
- That is most unwise. - Yes, of course, Teal'c.
Colonel O'Neill is determining if the vessel can be salvaged.
Very well. Keep me apprised. Hammond out.
This is strange.
Before they left, they initiated a self-destruct sequence.
- The countdown's stuck. - It doesn't make any sense.
It can only be stopped with a command override,
but that would erase the sequence, not suspend it halfway.
Is the ship going to explode or not?
Until we know why it was suspended, we can't be sure it won't start up again.
We need to do a diagnostic.
Carter! You and Davis, see if you can disable that self-destruct altogether.
- Yes, sir. - Sir.
Are you seriously considering salvaging this ship?
Why, yes, I am, Jacob.
- This ship belonged to Anubis. - Excellent!
What if it's a Trojan Horse?
Then, apparently they did it wrong.
Jack, none of this makes any sense,
so before you slap a US Air Force sticker on the side of this ship...
Will you stop?
We gotta check things out to see what happened before we do anything.
And find out why it's in Earth orbit.
Our orders are to recover technology that can help us defend against the Goa'uld.
I'd say this ship falls under that heading, wouldn't you?
- OK. - Thank you.
Sometimes I worry that you're gonna get my favourite planet wiped out.
Yes. What planet is that?
If they wanted to scuttle this ship and the self-destruct didn't work,
their next logical option would be to sabotage the hyperdrive.
Friesen, let's go.
I'll do a systems check from here.
Find out what that sound is.
What's the problem?
- Dad, this is Sam. - What's up?
We're going to the computer core but can't access this corridor.
All right, hang on.
The whole section's sealed off and the life support's been shut down.
- Why would they do that? - I have no idea.
I'll see if I can open it up and get the ventilation going again.
Colonel, we should also check on the shield generators.
- Jacob? - How's the hyperdrive?
Friesen says the engine checks out but he wants to look at the shield generators.
Does he say why?
- Why? To see them. - To see them?
Never mind.
If this ship destroyed an Asgard ship, then its shields were superior to any...
- We're in. - Just be careful, Sam.
Yes, Dad.
Whoa!
Something bad definitely happened here.
Dad, we're outside the computer core. The door's been hit by several staff blasts.
It's the only door I can't open. The circuits are fused.
It's almost as if there was a deliberate overload.
It looks more and more like a saboteur on board.
Someone damaged the computer and sealed it off so it couldn't be repaired.
Whatever happened, I can't get you inside.
- Colonel, have you been monitoring? - Affirmative. On my way.
I have to blow something up. Head back to the peltak, see if Jacob needs any help.
Shall we?
- Whoo! That was loud! - What?
Jacob, we're in.
This is fantastic.
No. This is fantastic.
Shield generators...
Hello?
Colonel O'Neill?
Why would he bring me here if I'm not allowed to contribute anything?
This is your first mission.
It may take time for Colonel O'Neill to gain confidence in you.
- So it was the same for you? - No, it was not.
Oh...
You know, I heard the rumour that... I only got this assignment
because Colonel O'Neill didn't want a Russian on the team.
Such rumours are meaningless. O'Neill would not have chosen you
if he did not believe that one day you would be an effective member of SG-1.
Thanks, Teal'c. I really appreciate that.
Those of us who aren't originally from Earth have got to stick together, right?
Are you suggesting an alien conspiracy?
No!
Oh!
Of course, yes. I was warned about your occasional use of humour.
You got me.
No conspiracy.
Computer log confirms that this is the same ship Thor was aboard.
And?
It could explain a lot, sir.
Thor's brain was directly linked to this computer.
Anubis may have underestimated the power of an Asgard's mind.
And?
It's possible that Thor was able to rewrite some of the ship's programming.
Maybe even leave something behind.
- Like a virus? - Exactly.
By interfering with navigation, life support,
a complex virus could have made Anubis abandon ship.
Might explain why the self-destruct got stuck.
He could've generated a new subroutine
that sent this ship to our solar system after it was abandoned, like a... gift.
I know it sounds a little wacky, sir,
but the more I think about it, the more it seems like the best explanation.
Wishful thinking.
If this ship wasn't intended for us to find,
why did it travel halfway across the galaxy all by itself?
For that matter, why didn't the self-destruct just go off?
I doubt a virus will know the difference between us and the Goa'uld.
There has to be a way to disable it or Thor wouldn't have sent the ship here.
Dr Friesen, this is Major Carter. We could use your assistance in the computer core.
Friesen, come in.
- Dad, have you seen Dr Friesen? - Negative.
You scientists! Stay here. I'll find him.
- It's a big ship, sir. - I think I know where he went.
It's comin' out of the ship's intercom.
- What is? - The sound we keep hearing.
You hear that? There's a pattern to it. Almost like distorted words.
Let's check it out.
Carter, I want you and Davis back in the peltak with Jacob.
- What's going on, sir? - Friesen's dead.
Jacob, come in.
Jacob, do you read?
Jacob, come in.
Jacob?
Dad!
Colonel, we've got another problem.
I'll live. Go, go.
We're decelerating out of orbit. The drive controls are disabled.
We've got no way of altering course. We're gonna crash.
Teal'c, come in.
You are approaching Earth's atmosphere.
You know, we noticed that. You'll have to ring us outta here.
Standing by.
I estimate impact between 500 and 1, 000 miles west-southwest of Alaska.
The energy released will be massive. There could be a tidal wave.
Raise the shields and set inertial dampening to maximum.
That way the ship should survive in one piece.
Done. That's all I can do.
Teal'c, we're heading to the ring room.
Wait, wait, wait.
Teal'c?
We have been attacked by Jaffa from the mothership.
What's your situation?
They are no longer a threat to us but the ship has been damaged.
The crystals that receive ring transmissions were destroyed.
There's insufficient time to dock aboard the mothership.
Well, I guess we're goin' in.
The official line is that early this morning, at 0800 hours, NORAD tracked a meteor.
It entered the Earth's atmosphere and landed in the north Pacific.
So far, no word from the Chinese government,
but I'm sure we'll hear from them soon.
As for the Russians, I have a call going through to Colonel Chekov in ten minutes.
Yes, sir. I'll keep you apprised of any further developments.
Gentlemen, it's good to have you back.
We've located the mothership. Sonar readings suggest it's still intact.
- Then they may still be alive? - We're assuming so.
There's a Deep Submergence Rescue Vehicle en route,
but we have to figure out how the crew will access the mothership.
Its escape pods are jettisoned through pressurised tubes.
Maybe one of them could be used as a point of access.
Sounds like our best shot.
Teal'c and I would like to join the rescue operation.
- There's a plane waiting. - Thank you, sir.
I should've been with them.
You believe you could have prevented this?
Maybe. You don't think so?
It was an ambush. Your presence would have made little difference.
Like on the cargo ship?
You did not know Jaffa would ring aboard.
I stood there. You saved my life like Dr Jackson did on my planet.
I didn't do a thing.
It is my understanding that it was largely your idea
that led to the disposal of the other Stargate before it could be detonated.
- You saved the lives of millions. - That was an intellectual exercise.
I'm talking about knowing what you can do in the heat of the moment.
One can never be certain until the opportunity arises.
Well, so far, my track record is not great.
Perhaps that is so.
But there are many battles left to be fought, Jonas Quinn.
How ya doin'?
Aside from the burns, I got a broken collarbone.
Selmak's working on it.
You know, for guys with no life signs, those Jaffa did a bit of damage.
They must have been trapped in the section of the ship that was sealed off.
To stay alive, they would have gone into a deep state of kelno'reem,
slowing down their heart rate to one or two beats per minute.
In that condition, the cargo ship's sensors weren't sensitive enough to pick'em up.
Think there are any more running around?
I doubt it.
My guess is the three that attacked me were on the computer-core level.
I let'em out when I opened the door to allow Sam inside.
We've got life support operating at 50%.
Won't be too comfortable, but at least we won't freeze to death... right away.
- Can we fix the engines? - Not a chance.
And that's not our only problem.
We found evidence of structural damage, probably a result of the impact.
- How bad? - I'm not sure.
The exterior pressure's pretty severe, especially on the lower levels.
It could compromise the hull.
Well, help will be on the way.
There's also the self-destruct sequence frozen halfway through its countdown.
- You haven't turned that off yet? - No, sir. I'm not sure we should even try.
Why?
First the door to the computer core was locked.
When the Jaffa tried to get in, the section was sealed off and life support shut down.
- By who? - It's "whom".
Actually, sir, it's more like "what".
- What? - The virus Thor left behind.
Exactly. What if it was trying to defend itself?
So Thor leaves behind a virus that forces Anubis to abandon the ship,
and this virus defends itself against the Jaffa Anubis left behind to blow the ship?
Or maybe it was left here so we could find it.
Sir, I'd like to return to the computer core.
I'll go with you.
Sir, we just got word from the task force. The DSRV is in the water.
Major Davis is right. It is definitely coming through the ship's intercom.
Maybe the virus is trying to talk to us.
What the hey?
Dad, we've got evidence of flooding here.
Stand by.
There's been a hull breach on the engineering level.
We're nowhere near engineering.
Sea water penetrated to the access shaft,
and now the pressure's pushing it up through the core of the ship.
- We're flooding from the inside. - Dad, the door's closing behind us!
It's a security measure. All doors are sealed around the breach.
I'll try to open it from here.
- It's a bit chilly. - Dad, how's it coming with that door?
This could take some time, Sam.
We have visual contact.
Sorry, sir, I can't bypass the system locally.
Jacob?
I can't get access to the security program.
- I'm goin' down there. - The local controls are locked out.
I'm gonna try to find a back door to the program.
How long's that gonna take? I'm looking at major shrinkage here.
I don't know. This is kind of a unique situation. Give me a few minutes.
How long will it take for this thing to fill up?
A few more minutes.
Yep.
Approaching point of entry.
Next time we crash our brand-new mothership, let's do it in the tropics.
It wouldn't make a difference. At this depth all water is ice-cold.
- Shallower water, then. Shallower. - Yes, sir. I'll keep that in mind.
Or we could just not crash at all.
Be nice to keep our new mothership more than a couple of hours.
Yes, sir.
- We could blow the door. - No. The concussion would kill them.
They'll be dead if we don't. We have to do something!
What do you think I'm trying to do, Major?
Your dad's cuttin' it a little close!
I can't do it.
Sam,
I'm sorry.
- What is that, Jacob? - Security protocol's been erased.
Jack, Sam, come in!
Jacob, this is Teal'c. We are on board the ship.
Jack and Sam are in trouble, main computer level.
- That's two levels down this way. - Remain here.
Dad, this is Sam. We're OK.
Yes!
Thank God! Sam, you really had me worried.
Tell him I take back everything I was thinking while I was underwater.
Whatever you did, it worked.
The security protocol erased itself.
- How is that possible? - I don't know.
Who cares? Let's go.
O'Neill.
Are you all right?
A little wet, a little chilly. The knee gets stiff in cold water.
We have a rescue submarine docked.
- We can't leave yet. - Yes, we can.
No, sir. Something else is definitely going on here.
Sir.
A message from the task force. The DSRV pilot reports they made contact.
SG-1's OK, but Dr Friesen's dead.
- Did they get them off the ship? - Not yet.
They're staying aboard for some reason.
It's definitely a voice. I'll see if I can clean it up.
- Why would it be so distorted? - Anubis probably tried to shut it off.
Carter?
The security program that locked us in that corridor didn't shut down by itself.
You think this virus Thor left in the computer is acting intelligently?
If that door hadn't opened, Colonel O'Neill and I would have drowned.
It knows who you are.
I got it.
I am using the internal communication system to synthesise my voice.
Thor spoke those words to O'Neill and I when we were imprisoned here.
Maybe what we've been calling a virus isn't a virus at all. Maybe it's Thor.
We got him off this ship months ago.
Not before Anubis downloaded his mind into the computer core.
If his consciousness remained intact,
he would be an independent entity operating within the system.
- His mind took control of the vessel. - Way to go, Thor.
The Asgard said Thor was on life support with little chance he'd come out of it.
So?
If we can download his consciousness from the computer,
the Asgard can transfer it into a new cloned body.
If that's what you wanna do, Sam, move fast.
The computer core isn't flooded yet, but it will be.
Wait. If Thor is in control of this ship, he's keeping the self-destruct on hold.
We remove that consciousness, the countdown will start up again.
How long will we have when the countdown resumes?
Approximately 17 minutes.
Plenty of time to get out of here after we've got Thor.
I know Thor was a friend of yours, but this is a Goa'uld mothership.
If we allow it to blow up, there'll be nothing to salvage.
Jack, this ship is never gonna fly again.
Having the supreme commander of the Asgard owe you one is more valuable.
Yeah. All right.
Next mothership we keep, OK?
Jonas, take Davis and Jacob back to the sub. Wait there.
- Colonel, I'd like to assist Major Carter... - Jonas.
- I'll take them back to the sub. - Thank you.
Here he is.
You sure you got all of him in there? He's a smart guy, you know.
- The self-destruct has been reactivated. - Let's go.
This door should not be closed.
Dang.
Corridor must've flooded.
- Jacob? - Yeah, what's goin' on?
Our exit is blocked. We need another way around.
All the other passageways into that section were already flooded.
There is no other way around!
I'll go back to the peltak, see what I can do.
Negative. Get that sub to a safe distance. We'll think of somethin'.
Understood.
I got nothing. How are you doin'?
- There's only one other way off this level. - The glider bays.
We can do that?
I've no idea.
OK.
The ship's self-destruct is activated.
We need to get the DSRV as far away as possible.
Jack, we're at the sub. What's your status?
Here's our plan, Jacob. We're gonna take a couple of gliders.
A glider isn't designed to operate underwater.
- It's our only shot. - All right, all right.
You'll have to activate the compartment's force field to stop the flooding.
Those systems went offline after the crash.
I know. I'm trying to reroute the power from here.
What is it?
The force fields allow ships in and out without depressurising the compartment.
If she can't get it online, she can't open the doors without flooding the hangar.
Right.
Sam?
Jacob, I want you to get that sub to a minimum safe distance.
- Understood. Let's go. - There's a control panel on this deck.
- I can reroute the power. - How do you know?
I've gone over mothership schematics a dozen times. I'm quick.
- Yeah? Well, where is it? - Don't wait for me.
Jonas!
No pressure, Carter. Plenty of time.
On the contrary, O'Neill.
Lots and lots of time.
Yes, sir.
Jack?
Jacob, will you please get outta here?
We are, but Jonas went off to try to get the force field online from a relay panel.
Listen... good luck.
What'd he say?
We are being advised that in seven minutes the ship will be destroyed.
Ah. See? Plenty of time.
This isn't tied into the primary system. I can't reroute the power from here.
The force field just came online.
- Nice! - It wasn't me.
Jonas.
OK.
Wait! Wait!
- Did it work? - We're about to find out.
Powering engines.
- Listen, if we don't survive this, thanks. - You're welcome.
Opening glider-bay doors.
Nice.
Hang on.
Whoa!
- Everybody all right? - Yes, sir. We're fine.
This is Jacob. We're seasick down here but we're in one piece.
- Glad to hear it. - What about Jonas?
All members of SG-1 present and accounted for.
Teal'c, take lead.
Are you smiling?
First time in a death glider.
Oh. Well...
