Previously on Stargate Atlantis.
It's probably the ancients' last line of defense before Atlantis.
Knocked out during the Ancients' last stand?
Or its power source is depleted. 10,000 years is a long time.
There's an unidentified craft about the size of a Wraith dart heading for the city.
- What's it doing? - It's scanning us.
- What are those? - Wraith hive ships. Three of them.
If they maintain direction and speed, they'll be over our planet within two weeks.
The Wraith were conducting experiments on your ancestors.
- You have some Wraith DNA. - She can actually see what's happening?
I am on a ship. I am in some sort of control room.
You are all so pathetic.
Something tells me that's not Teyla talking.
Chances are it was Teyla who gave away the location of our alpha site to the Wraith.
They know that Atlantis is the only way to get to a new, rich feeding ground.
Earth.
Not only has Teyla been able to ascertain that the Wraith are more interested in Earth than Atlantis
which is, you know, terrifying.
She realized that the hive ships will go right past
the only surviving lagrangian point satellite.
The last of what we assume were dozens of defense satellites, destroyed
during the Ancients' last stand with the Wraith.
Yes, yes, yes.
The point is, we think we can use it to our advantage.
I thought you said it was dead.
It is, but we think we've learned enough about how it works to bring it back.
If we are right about what is wrong with it.
Yes, of course, if we're right about what's wrong with it,
But if we're right, and it's just out of power,
The Wraith have simply been ignoring it.
Our preliminary estimates indicate a single naquadah generator would be enough to bring it back online.
Why can't we use our generators to get the weapons systems of Atlantis working?
Because those systems were designed to be powered by the zero point module,
and the satellite isn't.
And you think it's powerful enough to take out a Wraith hive ship?
According to the ancient database, it could take out all three when fully charged.
Keep in mind that the ancient technology is far superior.
They only lost the war because they were vastly outnumbered.
Well, we're vastly outnumbered.
And outgunned.
But they don't see the satellite as a threat.
In military parlance, surprise...
is an element on our side.
What do you need?
The satellite's 15 hours away by puddle jumper.
I recommend that we put together a small crew.
Say, myself, grodin... and a pilot.
- I'll go. - No, Miller can handle it.
Major, I need you to keep searching for alternate alpha sites,
just in case this fails.
The hive ships will be in range of the satellite in 49 hours.
We're going to need every last second of that time.
Questions?
Okay, let's get on it.
Well, Rodney...
I don't mean to put any undue pressure,
but at this moment, that satellite is the only thing standing between the Wraith and Atlantis.
No undue pressure.
I am fine.
I'm looking for something more enthusiastic than "fine."
I am ready to be put back on active duty.
I'm sure you think so, but...
- Tell him I'm fine. - She is, Major.
I see no further reason she should be kept here under medical supervision.
All right.
You're back on active duty.
I think I can handle this alone, Radek.
Is there not something better you could be doing?
I think I should go.
Yes, I agree. Go.
I mean on the mission.
Why?
Sure, you probably know a little bit more about the satellite than I do...
Generous of you.
But you know a lot more about the city than I do.
- I think I see where this is going now. - If, for whatever reason,
there is a problem there, it should be me, not you.
There's not going to be a problem.
Rodney, you don't know that. There...
If it seems like we can't fix it, we'll just turn around and come back.
Now, I realize I'm invaluable everywhere...
You know what? Forget about it. I take it back.
Sorry. Nope. You can't take it back,
Because you've just admitted that I am smarter than you are.
I admitted no such thing.
Oh, it was hard for you to say,
But the truth shone through, and you were compelled to speak.
You are a miserable little man.
Let's not ruin the moment here, huh?
Now...
keep an eye on my city for me while I'm gone, hmm?
Good luck.
Right.
All right.
MA5-393?
No, we've only been there at night, and it gets ridiculously hot during the day,
so, no, not really an option.
We wouldn't be having this problem if the damn alpha site that we'd picked hadn't been marked by the Wraith.
They're a real pain in the ass, aren't they?
Yes, they are.
How about M4H-212?
Nah, crawling with Genii spies.
Do you know that for a fact, sergeant, or is your "spidey sense" just tingling?
It's a fact, Sir.
Here we go...
M1M-316.
Stackhouse reported lush surroundings, and as far as his team could tell, it seemed uninhabited.
I'll get my team together and check it out.
Okay, good. Remember, Major, we don't need ideal.
I think we'd all settle for close.
I'm on it.
Major.
Is Teyla coming with you?
You're not seriously asking me that.
I think that's a bad call, Sir.
Here we go again.
All I'm saying is we still don't fully understand her connection to the Wraith,
and in my opinion I don't think we should expose her to information we wouldn't want the Wraith to have not
the least of which is the location of our evac site.
Doctor gave her a clean bill of health.
And that's good to hear, sir, but if she can't control how the Wraith use her.
- You don't know that. - That's right, we don't.
She saw everything they saw.
Who's to say they can't do the same with her, see what we see?
- If she's been compromised in any way... - She's an integral part of my team.
Period. End of story.
We're done.
This a simulation I've put together.
It shows how the city will be destroyed once we trigger the self-destruct.
So glad you felt I needed to see this.
I was just thinking how my nightmares need to be more vivid.
It's not going to be enough.
What?
Our self-destruct plan.
It's nowhere near effective enough.
Now, that seemed pretty effective to me.
Atlantis is more than just a city.
It is an intergalactic spacecraft.
Yes?
Yes, well, Teyla said the Wraith are not interested in destroying Atlantis.
They're coming here to get to Earth.
They can only do that by going throughthe Stargate...
Which means stealing the city, which is why we have a self-destruct in place.
Yes, but if they are even a least bit resourceful,
which I must assume that they are,
they can easily reverse engineer their own intergalactic engine from the wreckage on the sea bottom.
So we need a bigger bang,
break into smaller pieces?
Yes, well, that would certainly help, but I'm more concerned about the ancient database.
Its ability to back up data is incredibly redundant.
Incredibly redundant?
Yeah, that one never gets old, but, seriously, if the Wraith recover
even the smallest part of the ancient database...
that is my concern exactly.
All right, how hard would it be to destroy all the database terminals?
Impossibly hard.
We need to figure out a way to delete the ancient database.
Well, can you do that?
I can find out.
Okay, find out,
But before you wipe anything out...
Dr. Weir.
Yes?
We have an unscheduled off-world activation.
Major Sheppard is coming in hot.
What's going on?
They ran into some sort of resistance.
- I'm thinking Wraith. - Wraith?
I thought you said this planet was uninhabited.
It was.
I told you she was a liability, Sir.
Now, I'm not going to let your personal feelings endanger this facility any longer.
What?
Look, I'm not accusing you of doing it intentionally,
But the Wraith must be getting information from you.
What the hell are you talking about? We ran into a...
What the hell was that?
Looked an awful lot like a T-Rex, Sir.
Yeah, a T-Rex.
Wasn't even a Wraith, so why don't you check those accusations?
I take it you don't recommend the planet as an alpha site, Major?
Wouldn't be my first choice.
If McKay doesn't get the satellite online, we're screwed.
Dr. Weir, this is Miller.
We're approaching the satellite.
You're on the other side of the solar system, lieutenant.
You guys be careful out there.
Understood.
Okay.
Close the bulkhead doors.
Good luck.
- Right. - Good luck.
Sergeant Bates.
What is it?
You just accused me of disclosing our position to the Wraith.
Yes, I did.
Clearly you were wrong.
That's yet to be determined, ma'am.
Excuse me?
Look, I'm willing to accept that you're not fully in control of what information you give away,
But it's still my opinion that you should not be allowed to move freely around this base of operations.
Perhaps you are not aware, Sergeant, but being accused
of serving the Wraith is the greatest insult among my people.
Oh, I'm aware.
What the hell is going on here?
I was simply stating an opinion, Major.
She attacked me!
- And for good reason. - What reason would that be?
My guess would be the Wraith.
Walk away, Bates.
- Sir! - Walk away!
This isn't over.
I would be disappointed if it were.
What the hell are you doing?
You don't go around decking the head of security.
- He said... - I don't care what he said.
He says a lot of things.
You just stay away from him.
You okay?
Yes, why?
You're breathing pretty heavily.
Yeah, well,
just a little claustrophobic.
How much air do these things hold, anyways?
Eight hours.
Well, that's enough, right?
I mean, even with the heavy breathing?
I imagine they would calculate that in, right?
You're going to be fine.
Yeah, that's easy for you to say. You're not the one with the eight-hour ceiling on your breathing.
It's completely dead.
Well, we thought as much.
I'm going to hook up the naquadah generator, see if I can get some life support going.
Halling, hello.
May we speak?
Please, have a seat.
How is the evacuation on the mainland coming?
We'll be ready.
Good.
Dr. Weir, the word is there is a plan in place to destroy Atlantis.
There are concerns the Wraith would be able to make it to Earth if the city is left intact.
But I assure you that plan will only be executed in a worst case scenario.
Such as... three hive ships flying towards Atlantis?
We do believe we'll be able to destroy them before they arrive.
I understand you fearing for the well-being of your people...
but it is not reason to destroy the city of the ancestors.
Atlantis is a sacred place.
To even consider destroying it merely for self-preservation?
Merely for self-preservation?
This place is all that remains of the greatest race ever to inhabit the stars.
And you would prefer it fell into the hands of the Wraith?
I would have faith that the ancestors would not allow it to happen.
They have been able to preserve Atlantis for 10,000 years.
- Is it not possible... - No, i don't think it is possible.
Not if you're suggesting the Ancients will return in time to save their city.
You cannot know their plans for Atlantis.
They have made all the plans they are going to make.
Now it's up to us.
I thank you for your thoughts, Halling,
but I have to do everything I can to make sure the power and technology of Atlantis
does not fall into the hands of the Wraith , and, yes, to ensure they never make it to my galaxy.
Even if it means sacrificing the future of this one?
You know, the idea is simple enough.
It's the execution that is proving to be very difficult.
- You're creating a virus? - Essentially, yes,
A plain old computer virus.
Once introduced into the system,
it will wipe the database clean.
It could be downloaded as part of the self-destruct countdown.
It might even affect the Wraith's systems
if they try to access it.
How much of it could we save?
I'm sorry?
Of the database.
We brought a lot of hard drives with us.
How much could we transfer to our computers?
You mean, like, back it up? Take a copy with us?
Yes, exactly.
Using McKay's compression code, I'd say maybe 7%, maybe 8%.
- That's it? - Yes
Here we go.
Primary power online.
Looks like life support's now at 100%.
I think I found the switch to initialize the gravity.
Great, just give me a second to Oh!
That's permanent back damage.
Sorry, I...
assumed it would come on more slowly.
Well, you assumed with my life.
You'll be fine. It was just a little bump.
What do you got?
Looks like every system is back online...
except for the weapon.
Ah, details.
Let's get to work.
Oh, thank you.
Thank you.
Oh, yep. That's vertebra damage.
That's a life of pain.
What about M1K-439?
Which one's that?
The one with all the waterfalls.
Waterfalls.
See, now, why don't we just call it "planet waterfall?"
What?
I say we should just give them names.
Look, we've got a list of five planets here.
That should be enough potential alpha sites
to get Stackhouse and his team started.
Major Sheppard, we have a situation at generator station one.
- What's the problem? - It's Bates, sir.
- What about him? - He's been attacked.
Get a medical team down here.
Is he going to be okay?
It's still hard to tell.
He's got five broken ribs, a fractured collarbone,
and the concussion was quite severe.
- When can we talk to him? - We can't.
I've put him in a medically induced coma
until the subdural hematoma can be dealt with.
We won't be finding out what happened from him
any time soon.
Teyla and Bates got into it pretty bad yesterday, Sir.
A fist fight and a beating like this are a long drive apart, Ford.
I understand that, Sir, but
they were in a fight, and both looking to continue it.
Anything pointing to who did this?
I'm having a forensic exam of both his body and clothing performed right now.
Let us know what you find out.
Let's go get her side of the story.
Well, it's not a power generation problem.
The naquadah's pumping out more than enough juice.
Well, then why isn't it okay?
All right.
Let's just step back here.
Think about it.
This baby is a directed energy beam weapon.
Runs off a relatively low yield charge, like our naquadah generator.
So that means it's got to be continually building up a charge
in some kind of a buffer or a capacitor until it's discharged.
I think I found something like that.
Yes, here it is.
Right now, the buffer's at 90%.
Okay, so power is getting to the buffer, it's just not getting to the actual weapon.
Let me see if i can find a diagnostics program.
There must be one here.
Okay, we've got 29 hours until showtime, so let's hope we don't have to order parts.
You do not think I had anything to do with it?
Of course not.
You and Bates did get into it pretty good yesterday.
You know me, Aiden. I would never have taken it that far.
I know, so let's just see if we can't rule it out altogether.
Where were you last night?
I was here, in my room.
The whole night?
Yes.
So there's no way of knowing whether you blacked out or not.
I have no way of proving it, no, but I did not leave this room last night. I'm sure of it.
I did not leave this room.
You asked to see me?
Stackhouse has found a suitable alpha site, so should the need arise, we'll be able to evacuate.
Oh, that's good.
That's not why I wanted to see you.
You have to get me more than 7% or 8% of the database.
There has got to be a way of taking more with us.
Maybe 9%.
How do I choose between zero point module research
And their work on ascension?
Between weapons schematics and their notes on space travel?
No matter what we choose here,
invaluable information is going to be lost, and that is just the information that we've deciphered.
Now, we all know we have barely even begun to scratch the surface.
What if we destroy the cure for all disease?
Or even some piece of information that could lead to the downfall of the Wraith?
I don't know what I can tell you.
I will try to improve on McKay's compression ratios, but ...
we are at war, Elizabeth.
In war, there are casualties.
Schematics, anyone?
Looks like power runs internally from the buffer to the weapon.
I guess our guy took a hit that disrupted the main power conduit.
We need to reroute the power from our buffer to the actual weapon. If we can do that, it will arm.
You know, your masterful grip on the blatantly obvious continues to impress me, Peter.
- Thank you. - All right.
We need to... route power around these damaged circuits.
We do that, we should be laughing.
All right, I'm disoriented. Where are these?
They're outside.
What?
Look.
See?
Oh, great.
Someone will need to E.V.A.
There's nothing to hang on to.
I'm not saying it would be easy or safe.
Okay. So who goes?
Well, we could draw straws.
Brilliant. Okay, Miller, break out the straws.
It doesn't have to be straws.
Hey, we could do rock, paper, scissors.
Okay. On three. One, two, three.
Okay. Obviously rock, paper, scissors, doesn't work with three.
Anyone have a pencil?
Yeah, I think I've got one.
Well, get on with it.
Okay.
short piece goes.
You go first.
Well done. Good for you.
Miller?
You're best qualified to fix it anyway, Sir.
Flatter the dead man.
Good.
I know there's no love lost between her and Bates,
But I can't see her beating the hell out of the guy.
- Ford? - Ma'am?
What do you think?
I worry about what she might have done unknowingly.
The whole Wraith connection thing and her nightmares make me nervous.
Yeah, well, what are we going to do about it?
Stick her in the brig? This is Teyla we're talking about.
We have a situation on our hands.
- What's going on? - I completed the tests.
I found D.N.A On sergeant Bates' uniform.
- And it's not Teyla's? - No, Major.
Who is it?
I ran the test twice to be certain. It's conclusive. We have a Wraith in the city.
Someone tell me how this is possible.
How can a Wraith get inside the city?
They didn't gate in.
The dart.
What?
The Wraith dart that scanned us.
It made its way through the city, scanning for data.
The second it was done, it self-destructed.
So they beamed into the city?
Can they do that?
The same technology that is used to sweep people up and into their ships must work in the opposite way.
So the pilot of the Wraith dart scanned us, transmitted his information to the hive ships,
beamed down here, and destroyed his ship?
Yes, yes, it seems plausible.
That is precisely the time I started to sense the Wraith continually.
No wonder you were having nightmares.
What's he been doing here all this time?
Well, sergeant Bates was attacked near the naquadah generator that powers this tower.
The Wraith must have been doing recon. Maybe his job is to knock out the power
before the hive ship gets here, leave us dead in the water.
Or to make sure any self-destruct plan we had in place wouldn't work.
- Maybe a combination of both. - Exactly.
What we do know for sure is that we have a Wraith intruder in the city that we have to track down.
I have an idea.
We're away.
It's not much more than 30 meters away.
We're in position, sir.
Okay, Miller.
I want you to vent the atmosphere
and disengage the artificial gravity in the rear compartment.
Okay.
Open the rear hatch.
Oh, my...
Rodney?
Rodney, did you make it?
Haven't quite left the rear
of the jumper yet.
Do I need to remind you of the time?
Yes, please do, remind me.
Are we on a tight schedule?
Just pointing out the obvious.
Okay. Thank you.
One small step, huh?
One giant leap!
Sorry?
I made it.
Good.
Let's take a look at this first panel.
This is a biometrics sensor We've had online for the past month or so.
It detects irregularities in biometric rhythm
and reports them.
Wouldn't it have picked up on the Wraith?
Well, it requires significant amounts of power,
so we narrowed its field of focus to scan solely in the gate room,
figuring that was the only place that the Wraith,
or any other alien, for that matter, would likely enter the city from.
Okay, so that was wrong.
Yup.
Now, if I could only expand the scanning field to...
My god.
What?
That's him. Look.
It works very much like a life signs detector,
but it's able to distinguish different lifeforms.
- That's him? - That's him.
You can track him in real time?
Yes.
Ford, Teyla, we need two teams.
Let's go get him.
Yes, sir.
This is bad. Very bad.
I'm not sure I can fix this.
You can fix anything.
Who told you that?
You did, on several occasions.
Well, you're right.
It's probably a good thing I drew the short straw.
That's more like it.
The main power conduit's been severed.
There may be some way for me to reroute it so it's going through secondary conduits,
sort of like... a quadruple bypass.
I should be able to help you identify potential secondary conduits from here.
We're only going to have time to try this once.
Let's get started.
Is he still in place, doc?
Yes, he's still in the same room.
Hasn't moved since we located him.
Let's hope he's still sleeping.
Ford, Teyla, are you in position?
Almost.
My team's ready.
We're going to breach the room
At the same time from different directions. If he tries to get out the other door, take him.
Understood, Sir.
We shouldn't be more than a couple of minutes.
All right. Stand by.
Okay, that's all I can do from here.
Is the power getting through?
Yes, the power is getting through.
Oh, thank God.
Okay, i'm going to end this E.V.A.
We're coming in. We're going to pick you up and get the hell out of here.
Sounds like a plan.
All right.
Nothing will keep us from our new feeding ground.
You were on vox, Sir.
We heard the whole thing and double-timed it.
We got him, Major.
You're going to be okay.
Peter,
we're having trouble docking with the satellite.
See what you can do from your side.
Oh, dear.
"Oh, dear," what?
When we rerouted power from the buffer to the weapon,
It looks like we inadvertently routed power away from the docking station and the air lock.
That's going to be a problem.
All right, well, we'll do it manually, like we did the first time.
You had a space suit the first time. I don't.
The air lock isn't pressurized.
Then we'll...
look, I'll go back and reroute the power.
There isn't time for that.
The Wraith's ships are too close.
Yeah, well, i know what i'm doing now.
Rodney...
leave me.
No, we're not doing that.
Look, get to a safe distance,
And then come get me once the satellite has taken care of the Wraith's ships.
It's the only option, and you know it.
Besides, this way, I can power down the satellite Until they're well within range.
Then there'll be no way for the Wraith to realize
We've brought it back online.
All right, we'll cloak
And come back for you after it's done.
After it's done, then.
Good to see you on your feet, Sir.
How are you feeling?
You know, pins and needles.
I hate getting stunned by those damn things.
Has he said anything yet?
No, S,ir. Not yet.
Have you got a name?
Okay, we'll go with Bob.
Bob, I'm going to need to know
What you've been doing here for the past two weeks,
And I'm going to need to know now.
If you're not already powered up,
now would be a good time.
Powering up.
We should be weapons-hot
in 60 seconds.
Dr. Weir, it's McKay.
The satellite is armed and ready.
It should fire within the next minute or so.
Keep your fingers crossed.
Fingers crossed.
Good luck.
I don't think he's in a very talkative mood, Sir.
Yeah, I need to know what he's been doing
And whether or not he's been transmitting Back to the hive ships.
Wouldn't we have picked up a transmission?
We can send secure messages. There's no reason he can't.
Maybe I can try and connect with him.
I don't think so.
If the alpha site has been compromised, Major, we need to know.
Okay. See what you can do.
Switching over from manual to automatic firing mode.
Stand by.
Standing by.
Yes!
We have a kill!
Yeah!
We copy that, Rodney!
One down, two to go!
What are you doing, human?
You're trying to get inside my mind.
Allow me.
Teyla, stop it! Break it off!
Are you okay?
My wounds will heal.
Yeah, but for how long?
I need to know what you've done to this city.
Listen, Bob...
I have no problem with killing you whatsoever.
Come on, come on. Hit them again.
We have a problem.
What? What problem?
It looks like the circuit we rerouted has overloaded.
The weapon can't fire again.
I'm trying to find another pathway.
We're heading back in to pick you up.
Stay exactly where you are.
Look, we're cloaked. They won't see us.
There's no time. Just get the hell out of here!
I'm sorry.
Get us back to that satellite.
Oh, God.
I'm not screwing around, Bob!
Did you sabotage this base or not?
Those who feed upon you
Will know what you've done to me.
Yeah. We'll see.
Sir,
I think maybe we've gone a bit too far.
I don't think we've gone far enough.
Atlantis, this is McKay.
We have lost the satellite.
Did you manage to take out any more ships?
Negative.
Two other hive ships are intact.
Elizabeth...
Peter Grodin was aboard the satellite.
Understood.
What's the status of the other two?
They're not coming any closer. It looks like they're rethinking their plans.
At the very least...
he has bought us some time.
You can't do any more out there, Rodney.
Return to Atlantis.
We're on our way.
Put me on city wide.
May I have your attention, please?
This is Dr. Weir.
Our plan to stop the Wraith armada has failed.
They will make it to Atlantis.
Therefore, we must begin our evacuation plans.
I wish I could tell you all that this is a fight that we will win,
But I can't do that.
I wish I could tell you that we will find a safe harbor when we leave here.
I can't promise you that either.
I can tell you this...
up to now, you all have accomplished extraordinary things,
And I believe that even in the face of an uncertain future,
as long as we stay together, we have a chance to continue to do so.
Now, we all have our evacuation duties,
So thank you,
And I'll see you on the other side.
Dr. Zelenka,
put the virus program on standby.
I will tell you this...
no matter where you flee, we will find you,
just as surely as we will find Earth.
And when we do...
we will feast.
