P.A.: Incoming traveler.
Ahh! Phased it.
Welcome back, sg—1.
Thank you, sir, it's good to be back.
You're overdue.
Bit of a wild goose chase, sir.
The remnants of atemple we discovered
led me to believe we'd found kheb.
The planet sha're told me about.
Teal'c: However, there was no sign
of amonet's harsesis child.
Just rain.
Much rain. Wind, lightning, hail.
Did I mention the rain, sir?
Report to the infirmary.
Well, ithink we'd all like to change first, general.
I personally have mushrooms growing out my—...
P.A.: Attention all levels——stand by
for contaminated materials transfer.
Infirmary. Yes, sir.
Infirmary?
O'Neill: What?
Oh, I'm just escorting you up as a safety precaution, sir.
There's a big chemical spill on level 23.
What kind of chemical?
Tetrach loroethylen e ru ptu red.
Ru ptu red?
The entire level's been sealed off.
Hazmat team's cleaning it up now.
What?
There's no danger, sir.
Thank you.
Loosen your belt, please, colonel.
How's a needle in my butt
going to getwater out of my ears?
It isn't. Come on, sir,
you know this is standard procedure.
We should rethink this procedure.
So, Daniel, in our galactic meanderings,
if we happen to stumble across this narcesis child—...
Harsesis.
O'Neill: We're still talking about a baby, right?
What?
P.A.: Attention all levels:
Contaminated material transfer in progress.
Please remain at your posts until notified.
(Alarm sounding)
Listen, really jam it in this time, ok?
So, if sha're's child is already born
with all the knowledge of the Goa'uld,
it should be able to communicate at
a much younger age, right?
Colonel?
Daniel?
Just relax.
(Grunts)
Let's begin.
(Electronic beeping)
Dr. Fraiser: It must have something to do
with the alien symbiote within him.
It took an extremely large dose
justto sedate him in the first place.
What is the problem with the human?
Her body chemistry has been altered.
It is related to her prior infestation
by the dominant
parasitical species of this galaxy.
Is there a way to compensate?
I have not found it yet.
Place them in a holding cell.
Once the invasion is complete,
you may study them further.
Onlythen will we know if this is aviable
new home or not.
Come with me.
(Growling)
Dr. Fraiser: Take that one first.
(Alarm sounding)
P.A.: Attention all levels:
Contaminated material transfer in progress.
Please remain at your posts
until notified.
Repeat: Contaminated material transfer
in progress.
23?
No. This one's going to 16.
Unh!
Uhh!
(Beeps and buzzes)
(Zap)
Unh!
Teal'c...
Major Carter,
there is little time.
Are you capable of standing?
(Grunts)
Uhh! I feel sick.
You are suffering from the effects of a sedative.
What?
What's going on? Wha—...
What the hell happened to them?
They are not who they appear to be.
There's been an alien incursion within the s.G.C.
A what?
In the infirmary,
iwitnessed Dr. Fraiser and general Hammond speaking
of a procedure which had failed to work upon
both of us.
They spoke of invasion.
Well, how does that add up to aliens?
I saw 2 of them in their natural form.
Truly, they are alien.
Well, what about the colonel and Daniel?
We have to know what's happened to them.
(Knocking on door)
Come in.
Carter: It's locked.
It's not locked.
(Zap)
Ok. What about this chemical spill?
I believe it to be a subterfuge.
Not a single camera is operating on level 23.
P.A.: Incoming traveler.
Try punching up the gate, then.
There.
The colonel, O'Neill and Daniel Jackson
we know would not welcome aliens so blithely.
Imposters?
How do we know we're the only ones
who haven't been replaced?
There is no way of knowing for certain,
but if general Hammond has been compromised...
Then we can't trust anyone in the mountain.
Alert general Hammond.
The base was designed to keep people out, not in.
If we can make it to the south gate,
(alarm sounding)
Our escape has been detected.
We won't make it out this way now.
You are correct.
I will purchase time for you to depart this mountain.
Keep them busy as long as you can.
I'll come back for you.
Of that I am certain.
Ohh!
(Gunshot)
(Zap)
(Sizzles)
(Clicks)
(Owl hooting)
(Alarm sounding)
Uhh!
Unh!
P.A.: Airport sh uttles are located in the blue zone.
Hotel shuttles in the green zone.
(Hon ks) Look out!
(Brakes screech)
Maybou rn e...
This is major Samantha Carter.
We have a foothold situation.
Major Carter? Where are you?
I can't tell you that, sir.
If memory serves, there's an outdoor cafe
outside m.I.D. Headquarters.
In D.C.?
4:00.
Uh, I'm going to need a little more than that.
I repeat: We have a foothold situation.
Major, you are way outside your appropriate chain of command.
I have reason to believe that may be compromised, sir.
Understood.
(Airplane flying overhead)
(Electronic beeping)
Hey, Teal'c, how are you feeling?
You, uh, went a little crazy on us,
so we had to sedate you.
You remember what happened?
I do not.
Sg—I was exposed to chemical fumes from the spill.
You became delusional and attacked several people,
trying to escape from the base.
Teal'c...
Glad you're awake.
Has Dr. Fraiser explained the situation?
She has.
Good.
We're hoping you can tell us
where major Carter is.
She also had an averse reaction to the chemical.
One of the side—effects is hallucinations.
Paranoia.
Your symbiote protects you from a lot of things, Teal'c,
but apparently not tetrach loroethylen e.
Where is she?
I do not know.
Teal'c, if she doesn't receive medical attention soon,
she's just going to get worse.
I won't lie to you. She could die.
(Horns honking)
Hi, can I get you some coffee?
Please.
Thank you.
So, you came to the one person
you don't trust.
I don't know how far up the chain of command the infiltration goes.
It may well be contained within the s.G.C.,
but if general Hammond was compromised—...
He sounded fine to me on the phone.
What?
He called me, major. Calm down.
He's concerned for you. That's all.
I told you we had a foothold situation.
Major, a chemical spill causing
paranoid delusion
is infinitely more plausible to me
than aliens taking over the s.G.C.
My god.
You don'tthink I can tell the difference between the two?
What was ithinking?
Daniel: Oh, hi, Carter.
Maybourne, you are an idiot every day of the week.
Why couldn't you have justtaken one day off?
That's insubordination, major!
For crying out loud, maybourne,
cut her some slack.
She's not exactly herself.
And neither were we.
Sam, believe me, I know what you're feeling.
It's the chemical.
I don't believe it.
All right. Exactly what are the side effects
of this tetrach loro—— Ethel—mermaline stuff?
Hallucination, delusion...
Paranoid delusion, ithink it was, but go on.
Look, I know what I saw.
We were affected by the fumes
the moment we got in the elevator.
Didn't even realize it was happening.
Ivaguely remember having some water in my ear, that's it.
Dr. Fraiser injected me with something.
She was trying to sedate you.
She didn't give enough to Teal'c,
he sprung you and off you went.
He's fine, by the way.
Beat the crap out
of a couple of s.F.S,
but he's fine.
We're telling you th e truth, Sam.
You should've followed procedure.
I fully intend
to return with you,
justto make sure
everything's all right.
And you agreed to that?
Shouldn'tthat tell you something?
Iwouldn'ttell them where we were meeting,
until they agreed to my inspection of the s.G.C.
You have no idea what you're walking into.
I can take care of myself, major.
If I don't report back in a few hours,
you can rest assured that action will be taken.
We just want you to come back
so fraiser can check you out.
You're asking?
We're asking.
So, I have a choice? I can walk away right now?
Yes. Yes.
No. Maybou rn e...
Major Carter, you will accompany us
back to the base. If you resist,
you will be handcuffed.
No, she won't.
This is all very touching,
but I thinkthis very conversation
in this very public place
is evidence that major Carter,
in her current state,
is something of a security risk.
What's th e matter with you?
It's starting to wear off, isn't it?
You're starting to think straight.
That's exactly what happened to me.
I'm so tired.
We're going to go now.
I'd like you to come with,
but it's up to you.
All right.
Sure?
Good.
Plan e's waiting.
After you, major.
Maybe you'll remember
something later, son.
Please release me from these restraints.
I'm sorry, Teal'c.
There's still a chance you could relapse.
3 of the men you attacked have concussions.
(Telephone ringing)
Yes?
You're certain she's been located?
Very well.
Then we may begin experimenting immediately.
Your tax dollars at work.
Cozy little jet you got here, maybourn e.
You've alerted general Hammond to expect me?
Oh, yes.
He's awaiting your thoughts.
So, how, exactly, is Teal'c?
Oh, well, you know Teal'c.
Is the chemical spill completely cleaned up?
As of this morning, the Hazmat team
had gotten the last of it,
butthey're still going to keep
level 23 sealed off, until they can figure out
what happened in the first place.
(Clicks)
Carter? What are you doing?
Don't move.
Put the gun down.
She's hallucinating again.
Aah!
What the hell is that?
(Air traffic control chatter)
Sit down.
Look out!
(Mechanical roar)
Go checkthe pilot. He's one of mine.
You first.
Good enough? I'll keep an eye on him. Go.
General?
What is that?
I don't know.
What is that damn thing?
I already told you, I didn't know
that Jack was—...
Tell us how that thing works.
Sam.
Hold on a second.
(Low growl)
So this is how they look like us.
Where's the real Daniel? Is he still alive?
Maybourn e: You can talk to us now,
or you can talk to my colleagues later.
Either way, we'll find out
the information we need.
(Snarls)
(Mechanical roar)
Sit down!
(Growling)
Samantha with Daniel's voice: It works.
(Growls ouietly)
(Quiet growling)
It only creates an image.
I couldn't hear Daniel's thoughts or anything.
That must be whatthis one does.
Put that thing down, major.
Iwonder what caused their images to blink out?
They were just sitting there. Now, put it down.
Something interrupted both signals
at the same time, colonel. We should figure out what it is.
We were leveling off. Uh, cabin pressure.
This is electronic. It was more like interference.
Noise from the engines, maybe.
If we can replicate the condition, sir,
we can find it.
All right.
(Struggling ouietly)
Sorry, sir.
(Gasps)
What the—...
Who's that?
Major Davis.
Colonel O'Neill.
(Panting)
What's going on?
How'd we get like this?
You're asking me?
(Banging)
(Alarm system beeps)
(Buzz)
Hook him up.
(Souealing)
(Mechanical whirring)
Report?
Ithoughtthe sedative might be interfering.
Symbiote is quite resilient.
(Beeping)
So is he.
Put him back in the holding cell.
Major Carter is on her way back.
She may be less resistant.
(Squealing and whirring continues)
Aw! Ah! Ahh.
Davis.
The latch for that thing |s...
You found it.
Yes, sir.
If there's another fraiser, my guess is
there's another you and me walking around, too.
Why are we the only ones awake?
Maybe, uh... Maybe a malfunction.
(Whispering) Colonel, what are you doing?
I'm gonna wake her up.
Do——do you think that's such a good idea, sir?
It's an idea.
(Alarm)
(Alarm in the distance)
(Alarm continues)
(Alarm stops)
(Whispering) Maybe they didn't hear that
Excuse me.
That was weird.
(Quietly) Nice alien like you
has gotta carry a...
Hello.
What about the other thing?
The other thing.
(Whispering) Ok.
She'sjust an alien.
Just an alien.
(Quietly) Whoa, whoa.
(Quiet snarling)
Yeah, that's an alien, all right.
Why don't you find something to tie it up
(alarm system beeps and buzzes)
Hello?
Colonel?
Yes.
It's you?
Yes.
It's good to see you.
Oh, my god.
I figured they had to be keeping you alive
in order to access your minds, but...
Whoa. Hey.
Who are you?
Sir?
Oh, sorry.
Major Carter!
In that case, it's good to see you, too.
Every one of the people in this room
has been duplicated by the aliens, sir.
I noticed that.
The procedure didn't work on me or Teal'c.
We escaped, but Teal'c's been captured.
Where is he?
I don't know. I haven't had time to find him, sir.
Look, colonel maybourne's forces are moving in soon.
Maybourne? How'd he get a—...
I called him.
Willingly?
Colonel, in 29 minutes
those forces are gonna break down the front door
and shoot anything that resists.
We need to get our people disconnected.
Yeah. I pulled that headbandthing off of fraiser.
Her eviltwin came running.
Well, how did you two get free?
We just woke up
that must have happened when I killed you.
I'm sorry?
I killed the aliens
impersonating both of you on the plane.
Andthey don't know you did this?
I don't know, sir.
There is a specific tone that, if sustained,
will disrupt these devices.
The machine's in my lab.
Sir, we're gonna need more weapons.
Armory.
(High—pitch ed whirring)
Head on back to 23. Keep an eye on our people.
Yes, sir.
I've come for the bald prisoner.
(Alarm buzzes and beeps)
You will come with me.
I will submitto no further experiments.
Oh, but you will.
I'll take it from here.
Can't allow that, sir.
Oh, but you can.
Colonel O'Neill, I presume.
What gave it away?
(High—pitch ed whirring)
(Whirring intensifies)
That's it.
General Hammond.
(High—pitch ed whirring)
(Glass breaks)
(Growls ouietly)
P.A.: General Hammond, tech control.
(Snarling)
(Whirring tone)
Sure you're up to this?
As always.
You're an animal.
(Snarls) (Machine guns fire)
(Gunfire) (Squeals)

(Alarm continues)
(Aliens talking)

(Shrieks)
(Shriek continues)

(Shrill whirring)
(Whirring continues)

What the hell was that?
Carter: Colonel? On your 6.
What's going on?
I don't know, they just ran.
Perhaps there's an evacuation.
Well, we can't letthat happen, sir.
Why not?
They've had access to our minds.
They know everything about us.
Everything?
Everything.
(Alarm continues)
(Speaking alien language)
(Computer beeping)
(Speaking alien language)
(G rowls)
O'Neill: Close that Iris!
I can't, sir. It's overridden.
I'm shutting down the gate.
(Speaking alien language)
Everyone freeze!

(Alarm sounding)
(Mechanical door moving)
O'Neill: What happened?
Carter: They self—destructed.
Teal'c: Their destruction appears to be complete.
That's a lot of damage.
Coat of paint. Little touch—up.
It'll be fine.
Hammond: I've ordered p3x118 locked out
of our dialing program.
The human counterparts of those aliens
woke up spontaneously.
We're assuming the signals stopped
when they went th rough the Stargate.
Those who escaped still possess
all the knowledge obtained
from being linked to your minds.
That's creepy.
We changed all our codes. That's all we can do.
So, how did this happen, exactly?
The aliens came through the gate already impersonating sg—6?
Fraiser: We rushed them to the infirmary.
We don't remember anything after that.
General Hammond asked me to come here,
but wouldn't say why.
Presumably their next step after the s.G.C.
Was the Pentagon.
Samantha: Well, a high—frequency blast
from the harmonic generator
every time a team returns
should prevent it from ever happening again.
Colonel maybou rn e.
Good save.
I thought you'd like to know,
the alien posing as Dr. Jackson expired.
What of the aliens that were not caught
in the gate room explosion?
We're guessing they were linked to their leader
in some form or another when he self—destructed.
And what about the aliens that escaped
through the gate?
I guess we'll never know.
We'll have to hope the same thing
happened to them.
We appreciate your help in this matter,
colonel maybou rn e.
Credit major Carter. I do.
Well, I'm uh...
Sure we'll see each other again.
That'd be nice, Harry.
(Door closes)
