Aargh!
Let's go, Captain!
- Those gliders are comin' back! - This man's alive!
We cannot wait!
OK, come on! Come on!
Don't panic! We'll have you outta here in a minute.
Keep moving!
Teal'c!
I gotta go back for Carter.
Help me!
Go, go, I got him! Medic!
He's alive, but he's gonna wish he wasn't.
Let's get him outta here.
Carter!
We've got to go!
- Are you all right? - Yeah.
Let's get him outta here. Come on.
Dead. He had some kind of seizure. Bit his own tongue.
Keep it elevated.
No!
I want a full quarantine until these people can be examined!
- Colonel O'Neill and the rest? - Right behind me. And a dozen Jaffa.
Lock it up!
Carter,...
...you OK?
Yeah, fine.
Thanks.
There'd been no Goa'uld interference...
...for three centuries. The Nasyans are a...
.. were a peaceful people.
They were eager to form an alliance...
...and aid us in setting up a research outpost.
There was no warning.
We hadn't even spotted the mother ship when the gliders attacked.
It's not normal for the Goa'ulds to just show up...
...and wipe out a peaceful people for no reason, is it?
In the past, there was some reason.
They attack civilisations whose technology poses a threat,...
...but that wasn't the case here.
- Maybe they found out we were there. - How could they know?
More importantly, why did this Goa'uld care?
They might've been concerned because we just kicked the crap out of Apophis.
The truth is we still understand very little about their society.
I've seen the Goa'uld wipe out civilisations with no reason,...
...simply because it gave them pleasure.
So, what...? Nasya was just next on the list?
I wish it was that simple, but we can't underestimate them.
Maybe the reasons weren't made known to you, Teal'c. I mean, you are just a Jaffa.
I-I mean Apophis wouldn't necessarily explain everything to Teal'c,...
...even if he was first prime.
- Would he? - That is true.
I agree with Sam.
The Goa'uld are more complex than we're giving them credit for.
The better you understand the enemy, the better prepared you are in conflict.
Exactly.
What's the status of the Nasyan survivors?
We managed to rescue 237 people. They're critically burned.
Some of the overflow were transferred to the Air Force Academy Hospital.
The rest await relocation.
Proceed.
Sir, I-I think it's important to find out why Nasya was a Goa'uld target.
Agreed. But relocation is the first priority.
The three new SG teams, 10 through 12, will coordinate with you.
Dismissed.
Oh, Carter, I hate to be a nag,...
...but old Doc Fraiser says you haven't been checked out yet.
I'll go right now. Wouldn't want to break post-mission protocol. Right, Colonel?
Sorry to have to do this.
All right, open.
- Have you had a sore throat lately? - A little. Why?
There's a small abrasion back there. I'm gonna have to do a swab.
And open.
Cassandra's been asking about you.
Cassandra?
Yeah! I've been so busy lately.
She understands.
- OK! Let me know if it gets worse. - I'm free to go out tomorrow, right?
- We're researching relocation sites. - Sure.
Cassandra will be with me tomorrow. Why not stop by and spend time with her?
- I will. - Good.
Patient has third-degree burns to over 80% of his body.
So far, no sign of infection.
Incredible.
Hey.
- Is this one of the Nasyans we saved? - Yeah.
He should be dead.
Cassandra is in my office.
We still have rounds, but you know where it is, right?
Hey there.
Sam!
Euch!
Wow. Nice painting.
You really like it? My teacher at school says I have talent.
I love it.
- I missed you. - I know, I'm sorry. I've been so busy.
Very busy.
Cassandra, what is it?
It would be easier on the Nasyans...
...if there were an active civilisation willing to cooperate.
I'll bet the folks on P3X-422 would be...
Colonel O'Neill, there's an urgent call for you, sir.
Yeah?
Thanks for coming so quickly.
- What's going on with her? - I'm not sure. She won't talk to me.
She said she'd see you and only you.
Cassandra?
It's just me, honey. I've got Colonel O'Neill with me.
Hey.
Janet says you've been a little upset since Sam was here.
What happened?
She said she'd kill me if I told.
Well, you don't mean "kill you" kill you?
- No, I doubt that. - She said she would.
Cass,...
...Sam loves you. She'd never do anything to hurt you.
She would now.
Why?
She's a Goa'uld.
Where's the colonel? We're due to leave in five minutes.
He said he'd meet us in the gate room.
Well, step on it, then!
What was that?
Where's Colonel O'Neill?
Stand down, campers. We're on a hold.
- Why? - I don't know.
Some computer glitch.
What the hell was that?
That was enough to take down an elephant.
Open the Stargate!
Jack, what the hell is going on?
Open the gate now!
I command you.
God...
Open the gate now, or we will all die!
Hold your fire! Teal'c!
- I have a shot, sir. - And if she drops that grenade, what?
Nobody's gonna open that Stargate.
We're all gonna live,...
...or we're all gonna die right here.
Let me go! I must go!
Not gonna happen.
Take it easy.
I didn't know!
I wasn't sure until I saw her lose it down there.
Cassie was the one who suspected.
Cassandra still has naqahdah in her blood.
There may be a connection, a reaction that made her sense the Goa'uld.
How in the world did it get into Captain Carter?
Sir, I don't know.
I examined Captain Carter. There were no visible signs of entry.
She had a small abrasion in her throat. It could have been anything.
Are you saying it entered through her mouth?
The parasite attaches itself to the brainstem.
The soft tissue in the throat is a good place to start.
Oh, wait a minute. Wait a minute.
Oh, God! She was giving some guy mouth-to-mouth.
There was blood, but she said the guy just bit his tongue before he died.
If a Goa'uld can infest a human with no detectable physical signs,...
...then we'll have to start giving personnel an ultrasound or an MRI.
Let's make sure we haven't let any more Goa'ulds through the gate this time.
What would a Goa'uld be doing in a Nasyan man in the first place?
We didn't notice any of them acting Goa'uldish.
Maybe it was a setup. Trying to get a spy into one of us.
It is possible the Goa'uld within Captain Carter...
...has already placed a device of destruction on this base.
If there's any tampering here, I want it found.
Teal'c, I'd like you to help. You'll know what to look for.
Uh, what are we gonna do about Sam?
We're gonna get that damn thing out of her!
Well, that didn't work with Kawalsky.
And if any of those NID guys, like Colonel Maybourne, find out...
Well, they're not going to!
Right, General?
Agreed. I'm not giving up on Captain Carter either.
But until I'm presented with a viable option,...
...you're in charge of interrogating the prisoner.
Sir, I don't think that thing in her head's gonna tell me anything.
Colonel, we need to know what that Goa'uld's doing here.
Yes, sir.
I'm sorry to bother you.
Just a quick test here.
OK! Now, we have to get rid of some of those bandages.
Ough!
Oh.
Excuse me.
Your world is an amazing place.
It can be. Um, I'm... I'm Daniel.
You're one of the men responsible for saving us.
Yeah.
We owe you great thanks.
Could we, uh... Could we talk a minute?
Colonel O'Neill.
I thought you were helping with the sweep of the base.
I am on my way.
This is difficult.
Yeah. Yeah, it is.
Assault the Goa'uld's ego.
Make him appear foolish.
He may then reveal things, simply to make himself appear powerful.
Ah, come on, Teal'c. They're smarter than that.
I have seen many Goa'uld strategies revealed,...
...and certain victories lost because of Goa'uld arrogance.
It is the Goa'uld's greatest weakness.
Yeah.
Colonel O'Neill.
When you speak to her, do not see your friend.
How do you do that?
So,...
...you and I have got to have a little talk.
You really screwed up here, you know.
I mean, you really blew it.
You are weak.
Who's behind bars?
Your tactics will not work.
Not buyin' it, huh?
You must let me go.
Uh...
No.
You really have no idea why this is happening.
And I guess you don't feel like telling me.
This is a... picture of the man the Goa'uld came from.
It's my husband.
One of the other Nasyans recognised him.
We found this in our video archive.
And something was inside of him?
I know how difficult this is for you.
I lost my wife to the Goa'uld.
I'm sorry.
I need to know if you noticed anything different...
...about your husband lately. I mean... anything.
An injury, or, uh... new scars maybe?
Wait.
Here.
But it was months ago.
Months ago?
Y- y-you never noticed anything since then?
He wasn't acting strange, violently?
His eyes didn't glow?
I'm sorry.
I'll let you rest.
Let me go.
Let me go through the Stargate.
I will find another host and send your friend back to you.
You can do that?
Leave a host without killing them?
Yes.
It is possible, but not easy.
I could die, but I promise I will try.
The Nasyan man died when you left him.
The Nasyan man died first. That is why I left him.
He was beyond my natural abilities to heal.
What were you doing in him?
Carter's mind would be intact.
She would return to you as she was before.
You know I can't trust you.
I could've killed you all when you stopped me leaving.
You didn't want to die.
They would not have killed me. I am too valuable.
Which is exactly why we'll never let you go.
I have done nothing to harm you.
But you would not let me go even if you did believe me.
Oh, God!
He's telling you the truth!
Please, Jack!
No, Jack, please! Don't leave me, please! Give me a chance.
Don't leave me!
Please!
What will it take?
You have requested my presence.
Jaffa, you must convince the humans to let me go.
- They will not let you go. - They are impressive.
The Tauri have become powerful since the Goa'uld reign.
The System Lords will not allow this to go unchecked.
I can give the humans information to help defend themselves.
They are more powerful than you know. A Goa'uld attack on Earth was thwarted.
- A more powerful assault is being planned. - They are not fools.
They believe you are here to plant the seed of that destruction.
Not all Goa'uld are the same.
There are a few that oppose the System Lords and their ways.
You have heard of the Tok'ra.
Every Goa'uld seeks power...
...and would betray his own brother to achieve it.
Some seek power for a greater purpose.
Not every Goa'uld is an enemy to the people of this planet.
The Tok'ra are real, no matter what Apophis told you.
- I have yet to meet one. - You have now.
I am Jolinar of Malk-shur.
Oh, uh, excuse me. Sorry.
I just wanted to check on Talia.
How is she?
She's good.
- Rita? - Yes?
- Have you seen Dr. Jacobs? - Uh-uh.
What about the most recent blood work on the patient in 412?
- Here it is. - Good. Thanks.
Dr. Jacobs!
There is an old legend...
...concerning a group of Goa'uld who oppose the ways of the System Lords.
This group is called the Tok'ra.
This Goa'uld, Jolinar of Malk-shur, claims to be part of that group.
Can you be sure he is who he says he is?
I cannot.
Unfortunately, we do not carry identification.
OK. Let's try to build a little trust here, shall we?
One of the Nasyans we brought back was very badly burned,...
...but somehow he just got up out of his hospital bed and disappeared.
Who is he?
Must be the Ashrak.
It means hunter.
A Goa'uld?
Yes.
An assassin of the highest rank who follows the orders of the System Lords.
Who's he here to kill?
Me.
The missing Nasyan is an Ashrak.
A Goa'uld assassin sent by the System Lords to eliminate Jolinar.
That's the name of the Goa'uld in Sam?
It is.
Jolinar once tried to overthrow a System Lord,...
...but was defeated by Apophis.
He escaped during the slaughter of his armies.
It seems this Jolinar is wanted in Goa'uld town.
He claims to be part of the Tok'ra.
Resistance.
The Tok'ra is a small alliance of Goa'uld who oppose the System Lords.
My teacher Bra'tac first spoke to me of them.
This Goa'uld inside Carter could be lying. Spinning a tale to gain our trust.
It's quite a spin.
The sweep of the base turned up no evidence.
No tampering with the computer. We can't find any sign of sabotage.
That's why Jolinar didn't reveal himself to be a Goa'uld.
He was hiding out in the Nasyan man.
Until he was hunted down by the Ashrak.
When he realised we may have helped him escape through the Stargate...
He improvised.
So, where are we?
Bottom line, sir?
We may have a Goa'uld out there who's on a mission to kill Carter.
And we don't even know what he looks like.
Class one security breach.
Authorised personnel, check in at their designated security post.
- Excuse me. - Yeah, Doc. What's up?
- You're sending these people home? - Yeah, you could say that.
Daniel Jackson.
Yes.
You care about Samantha Carter as much as O'Neill and Teal'c?
Yes, I do.
Yet this is the first time you have come to see me.
I came to see if you could give us a description of the Ashrak.
I will know him only in the moments before he tortures me to death,...
...killing your friend along with me.
Well, there's no way he's getting in here.
You are not stupid, Daniel. Nor am I.
He doesn't know for sure you're on this planet,...
- ...let alone in this base. - He is Goa'uld.
He will find me. It's what he does.
Letting me go, trusting me, is the only chance of saving Samantha.
Then I'm sorry.
I'm sorry, Sam.
Alive I can be a powerful ally. Dead I am useless to you.
Then you'll have to give us more than empty promises.
I can give her back to you.
We can't let you go.
I'm not talking about Samantha.
I'm talking about Sha're.
I know where she is.
Who are you?
- John Adams. - You're not John...
Daniel, it's a ploy. He's playing on your greatest weakness.
That may be so. But this may be the only chance we have to see Sam again.
I believe Jolinar.
He told me about this resistance.
They're not like the Goa'uld. They don't take hosts against their will.
Right,...
...like Carter and this Nasyan guy.
No. He had no choice. He wants to leave Carter.
If they don't take hosts, how do they survive?
They take humans who are about to die,...
...who choose to continue to live and coexist with the Goa'uld.
Jolinar says this can be a rewarding relationship.
I'm sorry. I know what this means to you.
But I will never, never trust a Goa'uld.
Hammond.
The first group of Nasyans from the hospital have arrived.
Go ahead, soldier.
Uh-huh.
What the hell's that thing?
It's a ring.
Want a closer look?
Have a nice day, airman.
Boys.
As you were.
There's really no need to worry.
There'll be a team waiting for you on the other side.
Chevron one encoded.
Control room. Sir, it's the infirmary. They said it's important.
Chevron five is engaged.
Thank you.
The driver of the truck that delivered the Nasyans...
...just reported to the infirmary. Says he blacked out.
Doesn't remember driving from the hospital to the base at all.
Hold up security camera 1-6 Delta, please.
Teal'c, let's get down there.
Chevron six is engaged.
This is General Hammond. Security to level 16, holding room Delta.
Chevron seven is locked.
Interesting weapons these humans use.
Kree shac, Jolinar.
By decree of the Goa'uld System Lords, you will die with dishonour...
...by the power of the Harakash.
Hear this.
The days of the Goa'uld System Lords are numbered.
Tell them that I died with hope.
My death only feeds the fire that burns strong in the Tok'ra.
Agh!
This way! This way!
She's dead. Let's go.
Colonel! The prisoner and two guards are dead!
These two are dead.
Sam! Sam!
Sam!
Teal'c, get a medical team down here!
Come on, Sam.
Let's get her on the table.
I want an EKG and an EEG stat.
OK, on my count. Three, two, one!
- Good. Go! Where's my epi? - Got it.
One milligram.
Epi's in.
Thank you...
...for everything your people have done for us.
- You're gonna be OK. - I hope your friend will also be well.
Pulse is erratic.
We're getting feedback from the EEG. What is this?
Looks like interference.
- Two signals. - Isolate them.
You're picking up brain waves from the parasite.
Hey, I know you.
Oh, jeez.
Do not try to stop me or I'll kill him.
Doc?
I don't know. I've never been in this situation before.
The Goa'uld looks like it's dying and taking Carter with it.
- Release him, and you won't be hurt. - Turn it back on.
We can't do that. Let him go.
Turn the gate back on now, or he dies.
The parasite is still getting weaker.
Security alert. Intruder. Code red!
Parasite energy level is still falling!
- They won't let you go. - Silence!
Open the Stargate!
Let's cardiovert one more time. 40 joules.
I am sorry, Daniel Jackson.
Are you injured?
Dumb question!
But thank you.
I think.
You are welcome.
Just don't ever do that again.
The parasite is dead.
Try another milligram of epi. Then prepare for defib.
She's out of defib.
She's got a pulse.
Faint, but stable.
You did it, Sam.
You won.
It wasn't me.
Oh, yes, it was.
You hung in there. You beat it.
The Goa'uld gave its life for me.
It saved me.
Hey, Sam. How's it going tonight?
She's still the same.
Janet said that the Goa'uld left after it died.
That's right. Um...
It... It died, and her body's absorbing it.
She's the old Samantha Carter.
Same person we've always known.
Cassie, she's just a little sad right now.
But I'll bet she cheers up when she sees you.
C'mon.
Sam, it's me.
You're going to be OK.
