Exodus

"Exodus" is the twenty second episode of the fourth season of Stargate SG-1.

Synopsis
SG-1 return to Vorash to give the Tok'ra a Ha'tak vessel that once belonged to Cronus. But after learning Apophis and his fleet are coming to Vorash, they plan to evacuate Vorash, where Major Samantha Carter has a daring plan to send the planet's sun into a premature supernova, to defeat Apophis once and for all.

Previously on Stargate SG-1
After the Goa'uld Tanith deceives and murders the Jaffa Shan'auc, the Tok'ra use him to provide misinformation to Apophis. Teal'c sees a memory from his symbiote detailing the murder of his father Ronac at the hands of Cronus. Apophis is able kill Heru'ur and absorbs his fleet into his own. SG-1 with the help of their Android duplicates are able to defeat Cronus on the planet Juna and take possession of his Ha'tak.

Plot
A Goa'uld Ha'tak appears in orbit of the planet Vorash, the current main base of the Tok'ra. SG-1 transports down, much to Tanith's surprise. Colonel Jack O'Neill and Teal'c meet with the Tok'ra High Council where they reveal to Tanith that they know all about him being a traitor. He is then imprisoned and Teal'c visits him. He informs Tanith about what will happen to him and they also talk about Shan'auc.

On the ship the Tok'ra prepare to evacuate while Jacob Carter talks with Jack about the ship and the Goa'uld. Jack states that they are lending the ship in exchange for learning how it works; Jacob reminds him about when they tried to retrofit a Death Glider.(SG1:"Tangent") Jack states that they have been smart enough to steal the Ha'tak in the first place, more so than the Tok'ra have even thought to do. Jacob points out that SG-1 has been knocking down System Lords one by one, resulting in more power hungry Goa'uld to take their place, reducing the Tok'ra chances to defeat the Goa'uld once and for all. They have a plan but are still working on it.

In his cell Tanith talks with a guard and then collapses (and is said to be dead by the guard). When the guards enter the cell he kills them and flees. He returns to the surface and uses a Long range visual communication device to contact Apophis. Teal'c then searches for him together with the Tok'ra. Meanwhile Jack and Dr. Daniel Jackson are informed by Major Samantha Carter and Jacob that Apophis is coming and that they plan to destroy his fleet by blowing up Vorash's sun. This would be done by throwing the Stargate currently on Vorash into the sun while it is connected to P3W-451 – the planet where they found the black hole. The gate would suck in enough mass from the star to cause it to supernova. Jack agrees to the plan. Later Daniel talks with Teal'c about his revenge on Tanith.

After the Tok'ra are all evacuated, SG-1 and Jacob fly to the sun where they are able to connect the Stargate on board to P3W-451 as planned. They then send it to the sun and wish to flee. Suddenly an Al'kesh, a Goa'uld mid-range bomber, de-cloaks and attacks. Although Teal'c fires back he can only make one hit. Finally the Al'kesh is able to damage the ship, so that they can't enter hyperspace. Jack and Teal'c then board a Death Glider to fly to the Al'kesh but before they can fire it flies back to the planet. Teal'c follows it, despite Jack's worries. On the Ha'tak Jacob and Sam start to repair the ship's systems. At the planet Teal'c and Jack are able to destroy the Al'kesh (much to Tanith's shock, who was waiting for it on the planet) but they are caught in the explosion. Jack can only send an emergency call to the Ha'tak, where Jacob and Sam are partly successful with their repairs.

Back on the planet Jack and Teal'c are unharmed although their glider crash-landed. They intend to go to the Tok'ra base to find Tanith. However, Apophis' fleet appears and he sends two Jaffa to retrieve Tanith. The repairs on the Ha'tak are finally complete and so they can hide from Apophis. At the location of the rings Teal'c is shot with a staff weapon and Jack is stunned by a Zat'nik'tel, but is able to kill the two Jaffa attacking them before ringing back to the Ha'tak.

Jacob launches all the Ha'tak's gliders, which are programmed to flee the solar system. Apophis follows them but soon realizes that it was a trick. In the meantime Jack is rescued from the planet by his teammates. Finally, the sun explodes and SG-1 flees, while Apophis' fleet is destroyed. Suddenly SG-1's flight through hyperspace is interrupted and when Jacob scans the area they realize that they crossed four million light years in mere seconds. Apophis' mothership appears, trapped with them far from home.

Notable Quotes
Tanith: What is happening?

Jalen: Defense systems picked up a mother ship entering orbit.

Tanith: We must evacuate immediately.

Jalen: We have been expecting it.

(SG-1 and Jacob ring down to the Tok'ra base)

O'Neill: Hey, kids... we're not parked in a red zone, are we?

Teal'c: Tanith was surprised to see us.

Jacob: We didn't want to give him any warning.

O'Neill: He doesn't suspect you're on to him?

Jacob: Not that we know of. We'll see soon enough.

Teal'c: Of what do you speak?

Jacob: Well, thanks to the mother ship you're so graciously lending us...

O'Neill: It's not me. Hammond. It was an order, remember?

Jacob: Well anyway, we'll be able to move the Stargate to a planet not currently on the Goa'uld map. We'll finally be able to ensure the security of a more permanent Tok'ra base. As useful as Tanith has been in relaying false information to Apophis, we can't afford to take him with us.

Teal'c: What will become of him?

Jacob: We have a little surprise for you, Teal'c. Shall we?

Tanith: I must say, Colonel, I was most intrigued by your means of arrival.

O'Neill: Yeah, it's a sweet ride. Little rusty, but uh, it's still got zip, ya know?

Tanith: How exactly did a Goa'uld mother ship come into your possession?

O'Neill: Well it was kind of a... trade deal.

Tanith: How so?

O'Neill: Cronus gave us his ship. And he got what was coming to him.

(After revealing to Tanith that he had been used by the Tok'ra)

Tanith: You will never escape. The System Lords will hunt you down to the ends of the galaxy.

(Tanith is taken away by the Tok'ra guards)

O'Neill: That guy is a living cliché.

Jacob: I still don't think it's really necessary for you to be here.

O'Neill: Sorry, not lettin' her outta my sight.

Jacob: My mission is to oversee the relocation of the Tok'ra base. What's yours again?

O'Neill: Protect Earth's big fat asset.

(Upon using the rings to get inside the Tok'ra base)

O'Neill: (to two Tok'ra) So how do you guys know where to stand, anyway?

(The rings beams them down)

Jackson: Any sign of him [Teal'c]?

O'Neill: No, he's still looking.

Jackson: You guys have been out there for hours already.

O'Neill: Yeah, it's a Jaffa revenge thing...

Carter: This is the sun that Vorash is orbiting. It's a regular main sequence star with a core temperature of about fifty million degrees and enough hydrogen to burn for five billion years.

O'Neill: Yeah?

Jacob: We wanna blow it up.

O'Neill: Wow.

Jackson: That's, uh...

Jackson and O'Neill': Ambitious.

(After O'Neill's and Teal'c's crash-landing)

O'Neill: Ah, this is a bad idea. I said that, remember? Remember I said, "General, this is a bad idea!?"

Teal'c: I remember, O'Neill.

O'Neill: "Let the Tok'ra get their own ship," I said, "They don't share with us, why should we share with them?"

Teal'c: I remember.

O'Neill: Yep, that's what I said.

Teal'c: How much time remains before the sun explodes, O'Neill?

O'Neill: Huh? Oh... 45 minutes.

Teal'c: Then at least we have prevented Tanith from escaping.

O'Neill: Yes! At least we have that!

Goofs

 * From the moment they dial P3W-451, they should experience severe time dilation effects, but they are able to notice the successful connection to the other gate, engage a force field, open the cargo bay doors, and send the gate on its way all in regular time from their perspective. Furthermore, the plan itself - to explode the star while Apophis' fleet was in the system - would be affected by the time dilation. Apophis, being on the other side of the star and very far away than the gate, would have to stay in the system for a very long time in order to cover the few seconds it takes to trigger the explosion. The SG-1 team experienced a time distortion of several times being only a few feet away. The gate on P3W-451 has since moved much closer to the black hole, and the massively increased distance between the gate and the star vs the gate and Apophis would result in a time distortion effect orders of magnitude greater than the worst of what SG-1 experienced.
