We're gonna make it to the gate, but we're under fire. Teal'c's taken a hit.
What's your situation?
Tyler's hit and we're cut off, so get outta here.
- We can hold the gate. - Negative.
- We're not leaving without you. - Carter, don't argue with me.
Get reinforcements.
Sir. Receiving IDC. It's SG-1 .
Open the iris.
Close the iris!
- Report. - We were attacked by several Jaffa.
Lieutenant Tyler went down and Colonel O'Neill went back for him.
Let's assemble a rescue team and return.
Hold on. Who's Lieutenant Tyler?
- He's a member of SG-1 . - 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 gotta move, Lieutenant.
- Can you walk? - I can try.
Let's go.
We must return to the planet.
No one's going anywhere until I find out exactly what happened.
O'Neill and Lieutenant Tyler were cut off from the gate. I already told you.
- I've never heard of this Lieutenant Tyler. - How can you say that?
- Report to the infirmary. - 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.
The hell you are! Relinquish your weapons.
Airmen.
Major, I will authorise the use of force unless you relinquish those weapons.
- You are heavier than you look. - Sorry, sir.
That's no problem.
How's the leg?
It's no problem.
Yeah, right.
What is this place?
Well, I wouldn't buy a time-share, but it's defendable.
- Until Major Carter returns? - Yeah, and a whole lot of her friends.
Colonel... you could have made it to the gate.
You came back for me.
- What's your point? - I guess I'm grateful.
I wasn't gonna let you die, Lieutenant. It's, like, a ton of paperwork.
Paperwork?
It's a joke.
My way of deflecting attention from my own obvious heroism.
- You'll get used to it. - Oh, 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 MALP as a relay,
but apparently it's been disabled.
I've completed my preliminary exams of Major Carter, Teal'c and Daniel.
So far I've found nothing wrong.
They're obviously agitated, but that's understandable.
They have come back talking about a lieutenant who doesn't exist.
- You can't tell me there's nothing wrong. - I can't explain it, sir.
- Some kind of hallucination? - Hallucinations aren't normally shared.
There's never been a Tyler here.
Yes, sir, and we're still waiting for test results.
I want them quarantined in the infirmary.
Already done that, sir, as a precaution.
But they did insist I ask what you're gonna do about Colonel O'Neill.
If SG-1 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.
This is ridiculous. We should never have left the damn planet.
- You were ordered to by Colonel O'Neill. - Who could be dead, for all we know.
There's nothing we can do. There are heavily armed men just outside that door.
Well, we have to do something.
OK. Let's think this through.
Why would Hammond say he doesn't remember Lieutenant Tyler?
I don't think he's just saying it. I think he doesn't remember.
Yesterday we were all in the briefing room for two hours going over the mission.
I do not believe he would lie to us.
So he's suffering from some kind of amnesia?
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 and there is something wrong with us.
OK. When I went through the quantum mirror on P3R-233,
I came back to a base that looked just like this one.
Everything was the same, except 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.
There was nothing on 441 that even remotely resembled a quantum mirror.
Perhaps the Stargate malfunctioned.
We've never had any evidence to suggest the gate can access a parallel universe.
If Lieutenant Tyler does exist, there would be a record of him in the computer.
Yes. His personnel file.
My access code isn't working.
They must have 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.
Well, we've still got four mags, two clips, a little C4, some grenades and a launcher.
Is that enough?
It's a start.
No record of a Lieutenant Tyler on active duty at the SGC.
- Impossible. - Even day-pass visitors are logged in.
There is no way he could have been on the base and not be in the computer.
I configured a search for the name Tyler anywhere in the database. Nothing.
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.
This is weird. Somebody else configured an identical search less than an hour ago.
- Somebody outside the base. - Outside? How do you know that?
Because it's not a base ID. It's just a user number: 4574.
He's been busy. Over the past two weeks, he's accessed a number of secure files.
Mission logs, briefings, personnel files.
Whose personnel files?
Ours.
All right, listen up. We got a couple of MREs left, but we're runnin' low on water.
I'm gonna check the area.
Take the P90.
Wouldn't it be safer just to wait? The others should be coming soon.
They should have been here by now. Somethin' musta happened.
- Are you saying they're not coming? - No. It might take longer than we thought.
- What if they never made it back? - Hammond'll send someone else.
- How do you know? - 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 three clicks when I'm on the way back.
- So don't shoot me. - I won't.
- Sergeant? - I'm sorry, sir.
The second MALP was struck by zat fire shortly after reaching the planet.
- Launch the UAV. - Yes, sir.
Stand clear.
UAV 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 yoursituation?
We could use some backup, sir. Tyler's immobile and there's Jaffa all over...
(interference)
- Sir, we lost the signal. - He said Tyler.
Obviously he's been affected by the same hallucination as the rest of SG-1 .
That rules out sending a retrieval team until we know more.
Well, sir, if you like, we could try sending a second UAV.
I don't know if that's a good idea, General.
- Those things aren't cheap. - Colonel Simmons.
- You might wanna take a look at that. - My office.
Colonel, I understand you've been ordered to investigate a security problem.
When three of your team voice concerns about an imaginary friend,
it does tend to raise eyebrows.
Your own report suggests some sort of mind control.
- I have people working on it. - I'm sure.
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, but one day you'll play that card once too often.
I have an officer trapped off world
and there's nothing I can do for him until I get to the bottom of this.
Well then, sir, you should welcome my help.
Dr Jackson. Sit down.
Why?
I thought I'd give you an opportunity to explain what happened on that planet.
I filed a report.
Yes, you did. And a very 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 found this residue on Teal'c's jacket. I want you to have this analysed.
Yes, Doctor.
This is a video tape of your briefing before the mission to P7S-441 .
I see four members of the SG-1 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.
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.
A Goa'uld taking your ex-girlfriend as a host has everything to do with this.
What?
- You were very close. - That's none of your business.
- Your entire life is our business. - Do I need to call an attorney?
Serious questions have been raised concerning your viability here.
I am giving you an opportunity to respond.
OK, respond. Fine.
I lost someone I care about.
And not for the first time, I might add.
You think that makes me sympathetic to the Goa'uld?
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 Lieutenant Tyler you keep talking about, what does he look like?
- African-American, mid-twenties. - About five ten, five eleven?
I'm not sure, but I think I remember him.
Two hours ago 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.
OK. Maybe something did happen to us, but you were never even on that planet.
- I have to report this to Hammond. - Janet, wait.
If you come forward, they'll start suspecting you as well.
You need to find evidence. As long as we're locked up,
we can't do anything to help Colonel O'Neill. It's up to you.
I'd like to speak to General Eastman.
I'd like to know who this man is working for.
I appreciate that, sir. I needto know.
Mr Secretary, I wouldn't be making this call
if I didn't consider it of the utmost importance.
I know he's 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 there?"
Do you know what the Goa'uld really want from us?
Minnesota, that's what.
For the fishing, mostly.
I'll take you sometime.
- Fishing? - Oh, yeah.
Ask Teal'c. He can't get enough.
When do you think we'll get outta here, sir?
If not tomorrow, we'll head up into the hills and wait until the Jaffa lose interest.
They'll never stop hunting us.
What makes you say that?
Isn't... that the way they 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 mothership,
which was occupied by SG-1 and the Tok'ra Selmak.
You could have gotten them all killed.
At the time, I was made to believe that my time with the Tauri was a subterfuge.
- And now? - I am loyal to the Tauri.
Why should I believe you?
If I were still loyal to the Goa'uld, you would know it.
It would be immediately apparent. I would not hesitate to kill you where you sit.
(aircraft approaching)
Ah, crap!
- What is it? - Glider. Stay here.
- Nice shot. - Where in the hell did that come from?
Could be the glider we saw when we were checking out the crashed troop transport.
Right.
Anyway, it's made our position. Can you move?
- Not yet. - 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. It doesn't mean he wasn't there.
Don't you think it's odd that no one can corroborate your story?
Yes, I do. But what difference does it make? Colonel O'Neill is still out there.
You want us to send a rescue team,
based on your word that he's not been compromised?
- We'll go ourselves. - I can't trust you to do that.
Dr Jackson's motives for being here are coloured by his emotions,
and 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.
And last time we met, you harboured an alien in your own home.
I'm beginning to wonder whether all of this might have some residual effect.
Yesterday 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 been waiting for something to use against us.
Who are you getting your orders from, Colonel?
This interview is over.
Right, trips are set.
Take the nine mil. If we get into it, make every shot count.
- I cannot let you do this, Colonel. - Do what?
I cannot let you die, protecting me.
(Jaffa horn)
What have you got for us, Doctor?
I think I may have figured out what's been happening to SG-1 .
I found a foreign chemical on Teal'c's uniform and I've completed my analysis.
- What is it? - Well, I'm not 100 per cent sure.
But its structure resembles cortical acetylcholine,
a neurotransmitter that helps regulate and process human memory.
I believe that Lieutenant Tyler, or the idea of him,
is nothing more than a chemical implant.
Here, take a look. You see, the effect is greatest
in the temporal lobe associated with face recognition.
It's possible that SG-1 encountered someone on the planet
who exposed them to this, to convince them
that he, she or it was somehow familiar.
We're not talking about a vague sense of recognition,
but detailed memories from weeks before they set foot on that planet.
Their own minds provided the details necessary to complete that illusion.
Didn't your first report say that their MRls were clean?
They were. The chemical dissipates fairly quickly.
So what's 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.
This 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-1 could return and avoid further contamination.
We can't trust her.
General, please. This could be Colonel O'Neill's last hope.
I counted 15. Could get interesting.
Colonel, I'm not what you think I am.
I am not a member of your team.
I never was. I am not even human.
- My race is the Reol. - Take your position.
I exposed you to a chemical that made you think I was one of you.
- Get back there. - You don't believe me.
Look at my leg. It's almost healed. Would this be possible if I were human?
- Would 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 defence 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.
I broke free of my cell and damaged 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 a time to tell me. - Please... understand, Colonel.
(explosion)
Hit the C4.
Again!
Behind you!
(speaks Jaffa)
I think we're all clear. You all right, sir?
Fine.
Teal'c!
Lieutenant Tyler 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 trickin' people.
My kind do not embrace technology.
We've never been good fighters.
Our ability to disguise ourselves is our only advantage.
Now the Goa'uld are trying to learn our secrets.
We're being hunted to extinction.
You got someplace to go?
A group of us have started a colony on a planet in an isolated part of the galaxy.
After I return, we'll bury the gate and no one'll ever hear of us again.
(distant shouts)
- What have we got? - We are not alone.
Looks like they're gonna be there awhile.
We must act before further reinforcements arrive.
I don't think so, Teal'c. There's too many of 'em.
I'll surrender. Once they have me, they'll leave. I'm the one they're after.
That's very brave of you, but the last thing we need
is for the Goa'uld to figure out how you do that... thing you do.
Then I won't surrender. I'll just lead them away from the gate.
- That'll give you a chance to get through. - You said they'd never stop hunting you.
Now, we've trusted each other this far.
We could use a little more fire power, 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.
I like the attitude, Teal'c.
This is all my fault.
If I had 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?
I take it you're waiting to see me, Colonel.
Yes, sir. For the better part of an hour, in fact.
What about?
You allow your personal feelings to influence your command decisions.
How I run my command is none of your damn business.
- The security of this country, sir. - This has nothing to do with security.
Offworld teams have been compromised. Existing safeguards are ineffective.
SGC is an accident waiting to happen.
I don't know who issued your orders, but I've got a pretty good idea.
With all due respect, it doesn't matter.
What matters is that, in carrying out my orders,
I have found things to be very, very wrong here.
You're being used, Colonel.
I let this investigation go on long enough to make a few phone calls.
I learned enough to know your orders are politically motivated.
I think you're missing my point. I don't care.
If it's a fight you're looking for, my 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?
Hey, where's Tyler?
I would've asked, but I was too busy being unconscious
after he shot me with that zat you gave him.
Oh, for crying...
He's trying to be a hero.
There's only a few Jaffa left. We could take them out.
This may be our best chance for escape, O'Neill.
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? - 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 gonna try and hunt you 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 for ever.
And maybe then you can take me fishing.
