We're gonna make it to the gate,
but we're under fire. Teal'c's taken a hit.
Uhh!
What's your situation?
Uhh! Uhh!
Tyler's hit, too, and we're cut off,
so getthe hell out of here.
We can hold the gate!
O'Neill: Negative.
We're not leaving without you!
Carter, don't argue with me!
Get reinforcements.
Sir, receiving I.D.C. It's sg—I.
Open the Iris.
Close the Iris!
Report, major.
We were attacked by several Jaffa.
Lieutenant Tyler went down covering our 6,
and colonel O'Neill went back for him.
Let's assemble a rescue team and return
to the planet immediately, general Hammond.
Hold on. Who's lieutenant Tyler?
What do you mean, who's lieutenant Tyler? He's a member of sg—I.
What?
You assigned him yourself last month, sir.
Tyler, sir.
We've been training him for weeks.
This was his third mission.
Major, I have no idea what you're talking about.
We've got to move, lieutenant.
Can you walk?
I can try.
All right, let's go.
General, we must return to the planet immediately.
No one's going anywhere
until I find out exactly what happened.
Colonel O'Neill and lieutenanttyler
were cut off from the gate.
I already told you, sir.
And I'm telling you I've never heard of this lieutenanttyler.
How can you say that?
Ithinkyou should report to the infirmary.
Sir, there is nothing wrong with us.
We'll leave that up to Dr. Fraiser.
General, Jack is trapped on that planet.
Sergeant.
Escort them to the infirmary.
With or without reinforcements,
we are going back, sir.
The hell you are.
Relinquish your weapons.
Airmen.
Major Carter, I will authorize the use of force
unless you relinquish those weapons immediately.
Uhh!
You are heavier than you look.
Sorry, sir.
That's no problem.
How's the leg?
Uhh!
It's no problem.
Yeah, right.
What is this place?
Well, I wouldn't buy atime—share,
but it's, uh, defendable.
Until major Carter returns?
Yeah, major Carter and a whole lot of her friends.
Colonel...
You could've made it to the gate.
You came back for me.
What's your point?
I guess I'm grateful.
Well, I wasn't gonna let you die, lieutenant.
It's, like...
Aton of paperwork.
Paperwork?
It's a joke.
My way of deflecting attention
from my own obvious heroism.
You'll get used to it.
All right. I understand.
Right.
Fraiser: General Hammond?
Teal'c is going to be fine.
It's a bad burn,
but his symbiote should take care of it.
Any word from colonel O'Neill?
We've been trying to raise him
using the m.A.L.P. As a relay,
but apparently it's been disabled.
Well, I've completed my preliminary exams
of major Carter, Teal'c, and Daniel,
and so far I've found nothing wrong with them.
I mean, they're obviously agitated,
but that's understandable given the circumstances.
Doctor, 3 of my people
have just come back from a mission
talking about a lieutenant who doesn't exist.
You can't tell me there's nothing wrong with them.
I can't explain it, sir.
Some kind of hallucination.
Hallucinations aren't normally shared.
There's never been atyler in this command.
Yes, sir, and we're still waiting for test results.
In the meantime,
I want them quarantined in the infirmary.
Already done that, sir, as a precaution.
Butthey did insist I ask
what you're going to do about colonel O'Neill.
If sg—I has fallen under some kind of an alien influence,
anyone I send back to the planet
would be compromised as well.
Until we know exactly what's going on,
p7s—441 is off limits.
Yes, sir.
Carter: This is ridiculous.
We should never have left the damn planet.
You were ordered to do so by colonel O'Neill.
Who could be dead by now for all we know.
Jackson: It's not like there's anything we can do about it.
There are several heavily armed men just outside that door.
Well, we have to do something.
Ok, let's think this through.
Why would general Hammond say
he doesn't remember lieutenant Tyler?
I don'tthink he's just saying it.
I think he really doesn't remember.
How can that be?
Yesterday we were all in the briefing room
for 2 hours going over the mission.
I do not believe general Hammond would lie to us.
So what, he's suffering from some of amnesia, or...
If that's the case, they're all suffering from it.
Dr. Fraiser didn't seem to remember him, either.
Perhaps general Hammond is correct.
Perhaps there is something wrong with us.
Ok, when iwent through the quantum mirror on p3r—233,
I came back to a base that looked just like this one.
Everything was exactly the same,
except for no one knew who I was.
Because the Daniel Jackson in that reality
never joined the sgc.
Right. So what if this is a reality
where Tyler never joined?
Or maybe he was killed in an earlier mission.
Maybe he was never even born.
I don't know, Daniel.
There was nothing on 441
that even remotely resembled a quantum mirror.
Perhaps the Stargate malfunctioned.
Well, we've never had any evidence to suggest
that the gate can access a parallel universe.
If lieutenanttyler does exist in this reality,
there would be a record of him in the base computer.
Yes.
His personnel file.
My access code isn'tworking.
They must've decided that we're a security risk
and locked us out.
So you can't get in.
I didn't say that.
Where's your weapon, lieutenant?
I'm sorry, sir.
I dropped it when I got hit.
All right. Well, we've still got 4 mags,
2 clips, a little c4,
some grenades, and a launcher.
Is that enough?
Uh...
It's a start.
There's no record of a lieutenant Tyler
on active duty at the sgc.
That's impossible.
Even day—pass visitors are logged in.
There is no way he could've been on the base
and not be in the computer.
I configured a search for the name Tyler anywhere in the database.
Nothing.
Well, obviously someone is wrong here.
Could it be us?
I think we have to admit the possibility.
In either case, O'Neill remains in danger.
Waita minute. This is weird.
Somebody else configured an identical search less than an hour ago.
Somebody outside the base.
Someone outside the base? How do you know that?
Because it's not a base I.D. It's just a user number.
4574.
Wow, he's been busy.
Over the past 2 weeks, he's accessed a number of secure files.
Mission logs, briefings, personnel files.
Uh, whose personnel files?
Ours.
All right, listen up.
We've got a couple of mres left,
but we're running low on water.
I'm gonna check the area.
Take the p90.
Wouldn't it be safer just to wait?
Major Carter and the others should be coming soon.
The truth is, they should've been here by now.
Something must've happened.
Are you saying they're not coming for us?
No, justthat it might take longer that we thought.
What if they never made it back?
Then general Hammond will send someone else.
How do you know?
Because, lieutenant, we don't leave our people behind.
You should know that.
Yes, sir.
Good.
Stay off the radio.
Keep the channel open.
I'll give you 3 clicks when I'm on my way back.
So don't shoot me.
I won't.
Sergeant?
I'm sorry, sir.
The second m.A.L.P. Was struck by zat fire
shortly after reaching the planet.
Launch the u.A.V.
Yes, sir.
Voice on intercom: Stand clear.
U.a.v. Is airborne and beginning search pattern.
Try to raise colonel O'Neill.
Sg niner, this is Stargate command. Please respond.
We're still here.
Over.
This is general Hammond. What's your situation?
We could use some backup, sir.
Tyler's immobile and there's Jaffa all over—...
Sir, we lostthe signal.
He said Tyler.
Obviously he's been affected
by the same hallucination as the rest of sg—I.
That rules out sending a retrieval team until we know more.
Sir, if you like, we can try sending a second u.A.V.
I don't know if that's a good idea, general.
Those things aren't cheap
colonel Simmons.
Ithinkyou mightwant to take a look at that.
My office.
Colonel, I understand you've been ordered
to investigate a security problem.
Well, sir, when 3 members of your bestteam
start voicing concerns about their imaginary friend,
it does tend to raise some eyebrows.
Your own report suggests
that there might be some sort of mind control.
I have people working on it.
Well, I'm sure you do.
But we think that
an independent investigation is called for.
I'm sure we'll have your full cooperation.
You can use the red phone if you'd like, sir.
But one day you're gonna play that card once too often.
Colonel, I have an officer trapped off—world,
andthere's nothing I can do for him
until I getto the bottom of this.
Well, then, sir, you should welcome my help
Oh, Dr. Jackson.
Sit down.
Why?
Well, I thought I'd give you an opportunity
to explain what happened on that planet.
I filed a report.
Yes, you did.
And Avery interesting read it is—...
Full of amazing events and fictional characters.
Sit down.
Wait a minute. Let me see that.
Dr. Fraiser?
We got the blood work and DNA results.
No anomalies detected.
Thank you.
I foundthis residue on Teal'c's jacket.
I want you to have this analyzed.
Yes, doctor.
This is avideotape of your briefing
before the mission to p7s—441.
I see 4 members of the sg—I team.
I see Dr. Fraiser. I see general Hammond.
But I don't see any lieutenants.
This could be any briefing.
Take a look at the time code.
This is a waste of time.
This is not a waste of time.
This is an official investigation.
Oh, no. I mean, I get it.
We obviously have lieutenant Tyler issues.
I mean, I say he exists. You say he doesn't.
This is not just about lieutenant Tyler.
Someone else doesn't exist?
I'd like you to explain your relationship with Dr. Sarah gardner.
What does that have to do with this?
Dr. Jackson, I am here to investigate
potential alien influences over Stargate command.
The fact that a Goa'uld
has taken your ex—girlfriend as a host
has everything to do with this.
What?
You were very close at one time.
That's none of your business.
Your entire life is our business.
Do——do I need to call an attorney, or...
Serious questions have been raised
concerning your viability with this command.
I am giving you an opportunity to respond.
Ok, respond. Fine.
I lost someone I care about.
And not for the firsttime, I might add.
You think that makes me sym path etic to the Goa'uld?
I think that makes you someone whose judgment
can be easily clouded.
And for a man in your position,
that's unacceptable.
What's your position again?
I need to speak to major Carter.
Thank you.
What's going on, Janet?
I need to ask you something.
This lieutenanttyler you keep talking about—...
What does he look like?
African—american, mid—twenties.
About 5'10 ", 5'11"?
I'm not sure, but I think! Remember him.
2 hours ago you said you'd never heard of him.
I know. I can't explain it, but I can remember his face.
Does anyone else remember him?
I don't know.
Maybe something did happen to us,
butyou were never even on that planet.
I have to reportthis to general Hammond.
Carter: Jan et, wait.
If you come forward now,
th ey'll start suspecting you as well.
You need to find evidence.
As long as we're locked up in here,
we can't do anything to help colonel O'Neill.
It's up to you.
I would like to speak to general eastman...
I'd like to know who this man is working for.
I appreciate that, sir.
I need to know.
Mr. Secretary, I wouldn't be making this call
if I didn't consider it a matter of the utmost importance.
Yes, I know he's in a meeting with the joint—chiefs.
Do you have any idea when he might become available?
I see.
All right. Thank you.
Where are you from, Tyler?
Texas...
Mostly.
We moved around a lot.
You?
Born in Chicago.
Raised in Minnesota.
Is it nice there?
"Is it nice th ere"?
Do you know what the Goa'uld really want from us?
Minn esota, that's what.
Forthe fishing mostly.
I'll take you sometime.
Fishing?
Oh, yeah.
Askteal'c. He can't get enough.
When do you think we'll get out of here, sir?
Well, if not tomorrow,
we'll head up into the hills
and wait till the Jaffa lose interest.
They'll never stop hunting us.
What makes you say that?
Isn'tthat the way th ey are?
That may be the way they are...
But we're the way we are, so...
There you are.
Get some sleep
Tell me, Teal'c,
how does it feel knowing you betrayed your friends?
I betrayed no one.
You led apophis into the mother ship,
which was occupied by sg—I
and the tok'ra selmak.
You could have gotten them all killed.
Atthe time, I was made to believe
that my time with the tau ri was a subterfuge.
And now?
I am loyal to the tau ri.
Why should I believe you?
If iwere still loyal to the Goa'uld,
you would know it.
Really?
It would be immediately apparent,
as iwould not hesitate to kill you where you sit.
Ah, crap.
What is it?
Glider. Stay here.
Nice shot.
Where the hell did that come from?
Could be the glider we saw leaving the area
when we were checking out the crash ed troop transport.
R—right.
Anyway, it's made our position.
Can you move?
Not yet.
All right, time to dig in.
We have a problem here, major.
You say that this was your third op with lieutenant Tyler.
But based on your own report of sg—1's last mission,
you make absolutely no mention of his name.
Daniel's name doesn't appear in all of my reports,
that doesn't mean he wasn'tthere.
Don't you think it's kind of odd that not a single person
on this base can corroborate your story?
Yes, I do.
But what difference does it make?
Colonel O'Neill is still outthere.
And you want us to send out a rescue team
based on your word alone
that he hasn't been compromised.
We'll go ourselves.
I'm afraid I can't trust you to do that.
You see, Dr. Jackson's motives for being here
are colored by his emotions andthey always have been.
Teal'c changes sides more often
than I change the oil in my car.
What about me?
Well, let's see.
You were briefly taken over as a host by the Goa'uld.
Once you fell under the control of
an artificial intelligence of alien origin.
And the lasttime we met,
you harbored an alien in your own home.
I'm beginning to wonder whether all of this
might have some sort of residual effect,
because just yesterday, for example,
you violated base security
by trying to get into one of the mainframes.
I could nail you on that alone.
You're user number 4574.
The one who's been accessing our personnel files.
You don't care about Tyler.
You've just been waiting for something to use against us.
Who are you getting your orders from, colonel?
This interview is over.
All right, trips are set.
Take the 9 mill.
If we get into it, make every shot count.
I cannot let you do this, colonel.
Do what?
I cannot letyou die protecting me.
What have you got for us, doctor?
Sir, ithink I may have figured out
what's been happening to sg—I.
I found traces of a foreign chemical on Teal'c's uniform
and I've completed my analysis.
What is it?
Well, I'm not ioo% sure, but its chemical structure
closely resembles cortical acetylcholine,
which is a neurotransmitter
that helps regulate and process human memory.
I believe that lieutenant Tyler,
or the idea of lieutenant Tyler,
is nothing more than a chemical implant.
Here, take a look.
You see, the effect is greatest here,
in the temporal lobe associated with face recognition.
See, ithink it's possible
that sg—I encountered someone on the planet
who exposed them to this compound
in order to convince them
that he, she, or it was somehow familiar.
We're not talking about avague sense of recognition,
we're talking about detailed memories that go back
weeks before they ever set foot on that planet.
Yes, sir, and obviously their own minds
provided the details necessary to complete that illusion.
Didn't your first report
say thattheir mris were clean?
They were.
The chemical dissipates fairly quickly.
So what's that?
That——that's me.
I was exposed.
The chemical passed through a layer of plastic
which is probably why I experienced only a diminished effect,
butthis is how I figured it out.
You were exposed to an alien chemical
and now you claim to have "figured it out"?
Sir, knowing that
the contamination requires close proximity,
I am confident that sg—I could return to the planet
and avoid further contamination.
We can't trust h er.
General, please...
This could be colonel O'Neill's last hope.
Wh ew.
I counted 15.
Could get interesting.
Colonel,
I'm not what you think I am.
I am not a member of your team.
I n ever was.
I'm not even human.
My race is called the reol.
Take your position.
I exposed you to a chemical
that made you think I was one of your own.
Whatever. Get back there.
You don't believe me.
Look at my leg.
It's almost healed.
Would this be possible if iwere human?
Will you get down?
I'll show you.
Jeez!
What the hell is that?
A glimpse of my true nature.
You mean, what you really look like?
It's a natural defense mechanism—...
A chemical we produce in our bodies.
That's why I was a prisoner of the Jaffa.
They were taking me to be dissected and studied.
I managed to break free of my cell
and damage the guidance system of the transport ship
we crashed on this planet. That's when you found me.
I didn't know if you could be trusted.
You picked a hell of time to tell me.
Please...
Understand, colonel.
Aah.
Aah!
Aah! Unh!
Hitthe c4.
Aah!
Again!
Aah!
Unh!
Aah!
Behind you!
Aah!
Unh! Hat'tak!
Unh!
I think we're all clear.
You all right, sir?
Fine.
Teal'c!
Lieutenanttyler is not what he appears to be.
I know.
He told me.
Stand down.
Let's go.
O'Neill: Why didn't you just ask for help?
Tyler: I'm sorry, but I couldn't take the chance.
For generations, the reol have met with nothing
but fear and mistrust.
Well, sure, if you go around tricking people.
My kind do not embrace technology.
We've never been good fighters.
Our abilityto disguise ourselves is our only advantage.
Now the Goa'uld are trying to learn our secrets.
We're being hunted to extinction.
You got some place to go?
A group of us have started a new colony on a planet
in an isolated part of the galaxy.
After I return, we'll Bury the gate
and no one will ever hear of us again.
What have we got?
We are not alone.
Looks like they're going to be there a while.
We must act before further reinforcements arrive.
I don't think so, Teal'c. There's too many of them.
I'll surrender.
Once they have me, th ey'll leave.
I'm the one they're after.
That's very brave of you and all,
but the lastthing we need is for the Goa'uld
to figure out how you do thatthing you do.
Tyler: Then iwon't surrender.
I'll just lead them away from the gate.
That'll give you a chance to get through.
You said yourself they'd never stop hunting you.
We've trusted each other this far.
We could use a little more firepower however.
Daniel...
Stay with...
What is your name anyway?
Kaiael.
Ok, Daniel, you stay with... Tyler.
Carter, give him your zat.
Keep an eye out for patrols. Stay out of trouble.
The glider's Cannon may still be operational.
Like th e attitu de, Teal'c.
Tyler: This is all my fault.
If I'd revealed myself to you from the beginning...
This could have been avoided.
Well, we understand. No one's blaming you.
Please tell colonel O'Neill
I appreciate everything he's done for me.
What are you talking about?
Unh!
I take it you're waiting to see me, colonel.
Yes, sir.
For the better part of an hour, in fact.
What about?
I've come to believe
that you allow your personal feelings
to influence your command decisions.
How I run my command is none of your damn business.
Security of this country, sir.
This investigation has nothing to do with
the security of this country and you know it.
Offworld teams have been compromised.
Existing safeguards are ineffective.
Sgc is an accident waiting to happen.
I don't know who issued your orders, Simmons,
but I've got a pretty good idea.
General, with all due respect,
it doesn't matter who issued my orders.
What matters is that in carrying out my orders
I have foundthings to be very, very wrong here.
You're being used, colonel.
I letthis investigation go on long enough
to make a few phone calls. I learned enough to know
your orders are politically motivated.
Sir, ithinkyou're missing my point.
I don't care.
If it's a fight you're looking for, colonel,
my Washington connections go a lot higher than yours.
Administrations change, sir.
So do orders.
Now, do I need to have you escorted off my base?
That won't be necessary, general.
I know how to leave gracefully.
I only hope you do.
Daniel.
Aah!
Hey! Where's Tyler?
You know, I would have asked him,
but I was too busy being unconscious
after he shot me with that zat you gave him.
Aw, for cryin'...
He's trying to be a hero.
There's only a few Jaffa left.
We can take them out.
This may be our best chance for escape, O'Neill.
Unh!
Aah!
Aah! Aah!
Aah!
You're lucky you're not really a lieutenant under my command.
I'd have your ass for this.
You could have escaped.
We don't leave our people behind.
But...
I am not one of your people.
Could've fooled me.
Actually, you did fool me.
Come on, let's go.
What about the Jaffa at the gate?
O'Neill: They weren't a problem.
You know...
Before your people go and Bury your gate or anything like that,
you should know that not everyone you meet
is going to try and huntyou down.
We could be allies, you know.
It's not my decision to make,
but I will tell the others what happened here.
It might just convince them
that we don't have to hide forever.
And maybe then you can take me fishing.
