Narrator: Previously, onstargate sg—1.
Merlin?
King Arthur and the knights of the round table Merlin?
Yes. Was an ancient?
I think so.
What does this have to do with where this alleged treasure is buried?
Jackson: Certain threads point to the knights of the round table.
Gathering great treasures from the far corners of Arthur's domain
and hiding them in a magical stronghold at avalon.
(Grunting)
Teal'c: All free jaf'fa
have always had the greatest respect
for the warriors of the sodan.
Granting my freedom changes nothing, Mitchell.
(Alarm blaring)
We will meet again.
(Footsteps approaching)
You are still working on that thing.
Oh, hi.
Did you sleep here last night?
Of course not.
I slept down the hall in my quarters.
Sam.
This device was recovered from the cave under glastonbury.
Who knows what ancient secrets it may hold.
Well, obviously not you or Dr. Lee,
who's been working on that thing for, what, six months?
I think it's time we let the eggheads at area 51 take a crack at it.
Not yet.
I, I'm actually making some progress here.
That's what you said last night.
And I'm hankering for hash browns.
So let's go grab some breakfast.
Hey, this is interesting.
This is the first time one of my verification scans kicked back a positive result.
Does this mean I'm not getting my hash browns?
It means this device is interactive.
I'm reading an em output that keeps fluctuating
between high and low frequencies.
I'm gonna try to stabilize it.
Sure. What have you got to lose?
You okay?
Yeah, I'm fine.
What just happened?
(Electronic humming)
(Exclaiming)
Nicely done.
Can you read that?
My ancient's a little rusty.
Right. We need Jackson.
Hey, bill, good timing. Take a look at this.
Yo, doc, amazing discovery over here.
Bill, you okay?
(Electric buzzing)
Oh! What the hell?
What was that?
I don't know.
Okay, you're solid.
Carter: It's the device.
By initiating it,
we must have triggered some sort of localized effect.
Local meaning you and me?
Yeah.
Try picking up that coffee cup.
Oh, boy. We need to find Daniel.
"Out of phase." What does that mean?
It means we may have shifted to an alternate dimension.
And there are an infinite number of alternate dimensions.
No, no, no. That's alternate realities.
So, when the other sg—I showed up...
Completely different problem.
See, according to m—theory, that unites the five superstring theories,
there are several spatial dimensions.
11, actually, that exist in parallel with our physical realities.
Now, these higher dimensions...
No, I'll take your word for it.
That was alternate reality. This is alternate dimension.
Hell, all I need is a good time travel adventure
and I've scored the sg—I trifecta.
Now, how is Jackson supposed to help us with this?
Well, a similar thing happened to him a few years ago.
Px7—377, the crystal skull!
You really did read every report
from every mission we ever went on, didn't you?
I was in that hospital a long time,
and they were all riveting.
Anyway, when Daniel was out of phase and nobody could see him
except for his grandfather, Nicholas Ballard.
And because the same thing happened to Ballard in Belize,
Jackson should be able to see us
because we're all part of the same club.
Right.
Perfect.
(Water running)
Teal'c, have you seen colonel Mitchell?
No, I have not.
I'm gonna need to talk to your team.
Sg—I 2 just got back from p8t—474,
and it looks like we may have a timeline
for whatever it is the priors are planning.
According to the natives,
this "doomsday" the priors keep talking about
may be only days away.
I will inform the others.
Jackson, just the guy to help us with a little problem.
Or not.
The dimension we're occupying must be different
from the one he was shifted to.
Alternate, alternate dimensions?
Something like that, yeah.
Okay, so what do we do?
We have to find a way to communicate with them.
Any ideas?
(Alarm blaring) Harriman: (On pa) Unscheduled offworld activation!
What have we got?
No idc, sir, but I am receiving a radio signal.
Let's hear it.
(Electronic beeping)
(Static buzzing)
What's wrong with it?
Carter: Sounds like harmonic distortion in the data stream.
I'm not sure, sir. Landry: Can you clean it up?
I can try, sir.
(Thudding)
Okay, that sounded like something hitting the Iris.
Any way to know for sure what it was?
Harriman: We can run some tests.
Do it. Get colonel Carter down here
to help unscramble that message.
Yes, sir.
I can't make heads or tails of this.
That's because the filter coefficient has to be adaptive.
The filter coefficient has to be adaptive.
Hey, wait a minute. There you go.
Notice the slight variance in the output.
Notice it?
Come on! Notice it!
Never mind. Gosh!
What do you mean, they're missing?
They are not in their quarters,
nor are they responding to any attempt to contact them.
Is it possible they aren't even on the base?
We checked the front gate, neither of them signed out.
What about security footage?
We're reviewing tapes
for both the labs and the cafeteria, but beyond that,
well, there are hundreds of cameras and hours of tape, so...
We'll screen them all if we have to.
I want them found.
Boy, am I getting that Patrick Swayze in ghost feeling.
General, we need a whoopi.
Walter.
We managed to clean up the message, sir.
Finally.
Harriman: We noticed a slight variance in the output,
so we ran it through a sequence of digital filters,
and we came up with this.
(Static buzzing)
Man: (On recording) Stargate command. This is sodan.
Please respond.
Did he say sodan? Under attack.
Many have fallen.
We request immediate assistance.
That's when we heard the impact against the Iris, sir.
General Landry, we should investigate.
Agreed. Assemble a team.
Sir, colonel Mitchell is the one who should go.
He's the one who knows the sodan the best.
I agree, but colonel Mitchell isn't here right now.
Oh, hey, have you seen colonel Carter?
Hey, I was just coming to ask you the same thing.
Really? Because she left her laptop in my lab.
She did? Yeah, yeah.
It's, uh, hooked up to that device
that you picked up in glastonbury.
There she is.
Fast forward.
There's colonel Mitchell.
What just happened?
Looks like the camera went offline.
Probably a power surge.
They're gone.
Okay, bring up the security camera
for the corridor outside Dr. Lee's lab.
Sync them up to 8:16, and run them simultaneously.
(Computer beeping)
Okay, if they didn't go through the doorway,
how did they get out of the room?
More staff blasts, just like back at the gate.
Indeed. A battle took place here as well.
The sodan have been hiding here for thousands of years.
The only reason we got the transporter codes
is because colonel Mitchell won their trust.
I doubt they would've given them to anyone else.
And yet, evidently they were attacked.
By who?
My god.
Conway, Stevens, get back to the gate on the double.
Tell sgc we need med teams.
Yes, sir.
Check the area for survivors.
Whomever did this knew well the most efficient way to kill a Jaffa.
Their symbiotes have been targeted.
They were shown no mercy.
(Groaning)
Haikon.
Pulse is weak.
He will not survive long. His symbiote is dead.
Lieutenant, help me get him into one of these huts.
We need to get some tretonin in him, stat.
Roast beef.
The one time I can't eat, and they serve roast beef.
Do know how many times I've requested roast beef?
This is torture.
It's only been a few hours.
You're not the least bit concerned about this?
No one can see us or hear us.
We can't touch anything,
ergo, no eating, no drinking
and I'm not gonna speculate on the other bodily functions.
If they don't figure out a way to get us back...
They'll figure it out.
What have you got, doctor?
Well, we know that Sam was working on the device.
We know the device does not give off any typical energy signatures
emitted by ancient transporter technology.
This leads us to the conclusion
that they disappeared without leaving the room.
How's that possible?
Miniaturization.
Don't panic.
I have calculated the distance they could possibly travel on tiny legs
designated by this roped—off area.
All we have to do is find them.
Ronald, start with section 1A.
I was unable to locate any other survivors.
What is his condition?
We don't know if the tretonin's gonna take.
Even then, his injuries are pretty severe.
Without a symbiote.
Volnek.
Haikon, haikon.
Fear not, brother. You are among friends.
Teal'c, save yourself.
You shouldn't be here.
Tell me who has done this.
Tell me who has caused this devastation.
Volnek.
It was volnek.
One man did this?
Why would he turn on his people?
Tell me. Haikon.
Haikon.
Conway: (On radio) Major, come in!
This is hadden. Go ahead.
We're under attack, sir!
Requesting backup immediately.
(Guns firing)
McKenzie, you stay with him.
Oh, come on. It was just a theory.
Anyway, if I'd been right you'd all be calling me a genius right now.
Yes, but you weren't right.
So, anything?
Uh, nothing significant.
Fairly constant power readings
and slight traces of lepton radiation.
What?
Lepton radiation?
Lepton. Lepton radiation?
Yeah, but like I said, only traces.
I mean, there's nothing significant there.
Gotta go.
Stevens!
This one is alive.
I never saw...
The shots came out of nowhere.
No doubt volnek is using a sodan cloak.
We gotta get him back to the gate now.
(Beeping)
What's wrong?
The code is not working.
Someone has removed one of the control crystals.
Then how are we supposed to get out of here?
We cannot.
Come on, Jackson, figure it out.
I've already missed breakfast and lunch.
(Footsteps approaching)
General. Dr. Jackson.
I just came from Dr. Lee's lab.
Please tell me you have better news.
I've been going over some of the texts
we recovered from the cave in glastonbury.
And?
Well, a lot of them seem to make oblique references to arthurian legend.
For instance, the word "anwin"
which shows up several times is,
ibeheve, a variation on "unwin," the Celtic underworld,
where king Arthur journeyed in search of 13 sacred objects.
One ofwhich was a cloak.
What? The picture of the guy with the big, blowing robes?
Said to render the wearer invisible.
It was called "the mantle of Arthur" and was kept at barnsey island
by none other than our good friend, myrddin,
whom we know better as...
Merlin. Exactly.
I've no idea where you're going with this.
Me either.
It wasn't until Dr. Lee told me that he detected trace amounts
of lepton radiation from the device
that I was able to put it together.
You see, the crystal skull
that transported me to another dimension
also released lepton radiation.
And you think the same thing happened
to colonel Carter and colonel Mitchell?
You're damn right!
According to legend, the mantle makes the user invisible.
Now, given what I've read and what's happened today,
I'm guessing it wasn't literally a cloak at all.
It was the device we recovered.
It makes sense, sir.
Medieval historians could well have attributed
the powers of the device to a cloak
simply because they didn't understand it,
and they could've credited its recovery
to Arthur out of deference to the king
who was in power at the time.
Now, given what we know now, it seems much more likely
that it was Merlin who actually built the device.
So, why would Merlin build a device
that could transport him to another dimension?
Oh, today's daily double.
Uh, yea h, that's the part I haven't quite figured out yet.
Close.
But at least it points to the possibility that
both colonel Mitchell and colonel Carter
may still be somewhere here on this base.
We just can't see or hear them.
Hadden: We could make our way back to the gate on foot.
I do not believe that would be wise.
Thejourney would take months and the terrain is most treacherous.
There's not much for us here.
We're gonna run out of supplies before long.
General Landry will send an extraction team
when we fail to report.
And they'll end up stranded here, just like us.
We have food for the moment, and we can build shelter.
Perhaps when the extraction team arrives, we can repair the obelisk.
What about volnek? He's still out there.
Leave him to me.
Teal'c,
he took out an entire village.
It is my understanding that those who use a sodan cloaking device
are invisible to everyone but each other.
So if you use that thing, you'll be able to see him.
Indeed.
Didn't help that guy much, though, did it?
Now, when I was out of phase,
I could see and hear everything going on around me,
so it follows if they're in the same situation,
they're hearing what we're saying right now.
Except they can't respond.
Maybe they can. They just don't know it.
Now what does that look like to you?
First reaction.
A keyboard.
Uh, except there's no visual interface.
Not here.
You mean, it's on the other side?
It stands to reason that Merlin would want the device
to be interactive on both sides,
this and the alternate dimension.
Now, the interactivity on this side is difficult to access,
now, I'm guessing as a type of safeguard
againstjust anyone using the device.
But there'd be no reason to hide it on the other side.
Whoa, whoa, did you see that?
Oh, yeah.
Yeah!
Sam, uh, Mitchell, if...
If you can hear me, uh...
Okay, let's call this button "yes" and this button "no."
Okay, uh, first question,
are you guys okay?
Yes.
Yes, oh, thank god.
I mean, now we're getting somewhere.
Okay, um, besides the interactivity,
is there anything else unusual on your end?
Yes.
Something connected to the device?
Would you call it connected?
Yes, yes, yes. Yes.
Yes. Is it some sort of display?
(Tapping)
But that's... That's "emphatic yes."
Okay, thought so. Um...
Can you read it?
It's in ancient, isn't it?
(Tapping)
Okay. Uh, all right.
Now,
you guys are gonna have to help me translate what you see
but you see, we don't know what pressing buttons randomly will do,
so we're going to have to stick with "yes" and "no" and just do it,
one letter at a time.
Landry: This is gonna take a while?
Oh, yeah.
Well, just keep me posted.
Yes, sir.
Okay, um, first letter.
(Electronic buzzing)
Status?
Still no word from Teal'c or sg—12.
How long are they overdue?
Over an hour.
Tell colonel Reynolds to prep an extraction team.
Have them ready to move out asap
yes, sir.
Okay. First letter, next word.
Stop me when you see the right symbol.
How's it going? Fantastic.
We've almost completed the first sentence.
Listen, do you think you'll be okay on your own here for a while?
Sure, why?
We've lost contact with Teal'c.
Landry's sending sg—3 and 22 to check on him at the sodan village.
I figured I'd tag along.
Offworld?
Yeah, well, Jackson was able to travel through the gate
when he was out of phase, so, yeah.
Well, that's my point. You're out of phase.
What do you hope to accomplish?
Sam, Teal'c could be in trouble.
I wanna check it out.
No one can see me, I can't get hurt.
I can gather intel that no one else can.
Sam? Mitchell? Did you see it?
Listen,
I promise I'll come back through the gate when they dial to check in.
I'll only be gone a couple of hours.
Hello, are you guys still there?
Cameron... Sam, Teal'c may need help,
and I have friends among the sodan.
I'll be back soon, promise.
Like, slap a button or something.
Okay, thank you.
Um...
(Sighs)
First letter, next word, and stop me when you see the right symbol.
(Leaves rustling)
(Roaring)
Yes, okay. Next word.
Lee: That's it!
I got it. I finally figured out
what colonel Carter did to trigger the device.
I had to run a reverse scan on all the energy fluctuations
that we've been recording, put them through a program deflgnedtom
anyway, I isolated the algorithm she used
to synchronize the energy emissions coming from the device.
What?
Don't you see?
That means if! Counteract Sam's algorithm from my computer,
allow the emissions to return to their normal frequencies,
that could well reverse the process.
Oh, just give me a second. This is brilliant.
That should do it.
Sam.
Daniel.
Bill, I will never doubt you again.
Oh, boy.
Dr. Jackson, can, can you hear me?
If you can, press this button for "yes."
Teal'c. You all right?
It is a light wound.
Lieutenant.
What happened?
I found volnek.
Then you're lucky to be alive.
Haikon.
Others were not so fortunate.
Hadden: He woke up a few minutes ago.
What has happened to volnek?
Ten days ago he went to a neighboring world
to acquire supplies for our village.
Haikon: On the way back to the chappa'ai, he encountered a prior.
He was told that the sodan
had committed unforgivable treason against the ori.
The prior vowed that great ill would befall us
and then planted his staff into the ground.
Volnek returned to the village and told me of the encounter.
We took the threat seriously,
keeping a watchful eye on the chappa'ai.
Several days passed without incident until
volnek fell ill.
He became irrational, incoherent.
We isolated him and treated him with our best medicines,
but his condition worsened.
(Screaming)
Yesterday, he broke the bonds that were meant to restrain him.
Our finest warriors attempted to subdue him,
but he killed them all with very little effort.
He then turned on everyone in his sight.
His own brother, jolan, was killed in the carnage that followed.
Women and children fled to the woods
and volnek followed them and slaughtered them all
without mercy.
To the best of my knowledge,
I am the only one to have survived.
Rest, brother. Rest.
Reynolds: Sg—22 establish defensive perimeter.
Sg—3 stay close to me.
Colonel Reynolds.
Teal'c, what the hell happened here?
Why haven't you checked in?
The eye of the gods has been damaged.
We're trapped here and so are you.
The ori had a hand in what has transpired here.
The ori?
We have much to discuss.
Come.
Okay, if you're still there, I've given it some thought,
and my guess is it should be a simple matter of reversing the process.
I'm on it.
Is that supposed to be reassuring?
Where's Mitchell?
He went offworld with the extraction team.
What?
He was convinced he could help Teal'c.
I couldn't talk him out of it.
Why doesn't that surprise me?
There's no sense in worrying about that now.
On the bright side,
the translation will go a lot quicker now that you're here.
Jackson: Okay, this is interesting.
It appears to be a log of some kind.
Merlin was conducting research on some kind of new invention.
And it was something big.
He went to great lengths to try and hide it.
This device was invented for the sole purpose
of keeping his research a secret.
He needed a way to conceal it from...
(Electronic humming)
Daniel?
Merlin needed to conceal his research from...
His fellow ascended beings.
But if he was ascended
he must have retaken human form to perform his research.
I don't get it. What invention could've been so important
that it would have led him to give up his ascension?
A weapon.
A weapon capable of destroying ascended beings.
You hit him with two p—90s, and he didn't die? How is that possible?
We have encountered something like this before,
an ancient device capable of reanimating dead tissue.
Anubis used a similar technology
to give life to his kull warriors.
I'm assuming there's no cure.
The volnek we know is dead.
So how do we stop him, it, whatever?
By destroying the body entirely.
Claymores. Oh, that's what I'm talking about.
We just plant two of them opposite each other
and run a trip wire right through the middle.
Then all we gotta do is lure him in.
Piece of cake.
While we're at it, maybe we could teach him how to speak Japanese.
I will do it.
What?
Teal'c, the kill zone is gonna be huge.
You're gonna have to be awful quick to get out of it.
Understood.
No, no. Now that's just crazy.
Let's at least wait for reinforcements.
Waiting will only put the lives of others at risk.
Volnek was clever enough to disable the eye of the gods.
Undoubtedly, the missing crystal is in his possession.
The only way we can return to earth is to retrieve it
and the only way that we can do that is by killing volnek.
There is no other way.
Merlin believed that the ori represented a significant threat
to the safety of this galaxy, including the ancients themselves,
who refused to take any action
to protect themselves against them.
So he went ahead and developed the weapon anyway.
Well, he found a way of doing it
without their knowing about it
by shifting his research to another dimension.
So, the weapon, did... Did he ever complete it?
See, this is all technical. Way over my head.
I wish you understood ancient.
These notes seem to indicate that he completed the weapon here on earth
and then had to relocate it to...
I don't need to know ancient to understand what that is.
A gate address to where he hid the weapon.
Claymores are ready.
You and your men establish a perimeter.
I will lead volnek into the trap.
You sure you wanna do this?
I am.
Okay.
Uh, I'm going to try to make an adjustment to the algorithm.
It's a bit of a long shot, but if! Can get this to sync—up...
Mmm.
Uh—oh. Uh—oh.
Uh—oh.
Oh, no.
(Clears throat)
Hello, this is Dr. Lee.
I, um, I'd like to speak with general Landry, please.
Yeah, it's a bit ofan emergency.
You know, there's a fine line
between crazy—brave and crazy—crazy, my friend.
And you are walking it.
You realize he took out an entire sodan village?
You know, the last thing I need
is for you to get yourself killed.
You realize how long it will take me to find a replacement?
You worry far too much, colonel Mitchell.
You can hear me now?
And see you.
You're not surprised?
What is it? What's going on?
I'm not sure, but I may have accidentally
drained a significant portion of the machine's power supply.
How significant?
According to these readings,
it could reach critical failure inside 15 minutes.
And what happens to Carter, Mitchell and Daniel?
In all likelihood, we'll be permanently stranded.
So we can see each other when you're cloaked,
that means ifvolnek's cloaked he'll be able to see me.
All I've gotta do is get his attention
and lead him right back to Reynolds.
I do not feel comfortable allowing you to shoulder all the risk.
Ain't no risk. I'm out of phase, remember?
And you are certain you will not be injured?
Absolutely.
Hey, take your best shot if you don't...
Good luck, colonel Mitchell.
Did you even think twice about that?
I did not.
Huh.
Volnek!
Hey, volnek!
Volnek!
Where are you, homeboy?
Come on out and show me some of those monster moves!
(Snarling)
Oh, there you are. I was getting worried.
(Roaring)
Sorry. You gotta do better than that.
Come on, big fella!
(Laser beams firing)
There you go. Come on and get you some.
(Snarling)
We're running out of time. Okay, I think I've got it.
This is some kind of master control screen.
Yeah, here it is. It's a... It's a button combination.
Ifthis works, what happens to Mitchell?
I don't know.
It's possible there's still a subspace connection linking him to the device.
And if there isn't?
LAN dry: Doctor.
Lee: Okay.
I'm gonna try and make an adjustment to the algorithm.
It's a bit of a long shot...
You'd better be sure about this, doctor,
because if you make me disappear,
there won't be a dimension safe enough for you.
Come on, don't give up! Come on, come on!
(Snarling)
(Moaning)
Oh, crap.
(Laughing) You did it.
No, actually, I didn't.
It was Daniel. He figured it out.
Where's colonel Mitchell?
(Groaning)
(Roaring)
You know, the whole point of my coming here
was for me to rescue you.
You are most welcome, colonel Mitchell.
Let's see him get up from that one.
Unfortunately, we must now locate the crystal.
What, are you talking about this crystal?
I took it off him dunngthefight
you know, if we hurry we'll make it in time for dinner.
