Airdate: February 25 & March 4, 2005

Ba'al commands the System Lords, but now faces an even more formidable enemy in the Replicators. Even as Bra'tac and SG-1 prepare to launch a Rebel attack against the Goa'uld, their ship is attacked by Replicators, and Daniel is beamed away. Jacob arrives at the SGC and informs O'Neill that an all-out war has begun, and the Replicators will overrun the galaxy in a matter of weeks. The Jaffa rebellion also faces collapse as many rebels, fearful of the new menace, are repledging their loyalty to the Goa'uld. To revive the Jaffa rebellion, Teal'c proposes recapturing the most holy and symbolic temple of Dakara.

Carter and Thor cooperate to modify the disruptor weapon, however the Replicators quickly adapt and are once again immune to the technology. Meanwhile, Daniel finds himself a prisoner aboard Replicator Carter's ship, and she probes his subconscious mind, seeking the knowledge of the Ancients buried there. The sacred planet of Dakara falls quickly to the Rebel Jaffa forces, and Ba'al brings word to the Goa'uld lord whom he secretly serves. It is Anubis, who has survived his frozen banishment and taken a new host. Anubis orders his forces to disengage the battle with the Replicators and retake the temple at Dakara.

Replicator Carter succeeds in accessing the knowledge of the Ancients in Daniel's mind and learns that the one weapon in all the galaxy capable of destroying her is hidden within the ruins on Dakara. As the Rebel Jaffa prepare to defend Dakara from Ba'al's advancing fleet, Ba'al appears as a hologram at the SGC. He too has learned of the weapon on Dakara but he warns O'Neill that it must be destroyed before his fleet arrives to reclaim it. The weapon is capable of annihilating all life in the galaxy, and there is only one who would use it and survive such pervasive devastation - Anubis.

Anubis intends to use the Ancient device on Dakara to annihilate all life in the galaxy, and he has ordered Ba'al's fleet to reclaim it. Carter and Jacob gate to Dakara to locate and destroy the device before Ba'al arrives, and together they access the temple's chamber. Readings indicate that the device is similar to disruptor technology, and before destroying it, Carter and Jacob consider that it may be possible to modify the output of the device to be effective only against Replicators. However, to prevent the Replicators from adapting, the device would need to be activated throughout the entire stargate network simultaneously.

Ba'al's fleet arrives at Dakara where he is presented with an unusual proposition. With his cooperation to reprogram the stargate network, the Ancient weapon can defeat the Replicators in every corner of the galaxy at once. Ba'al agrees as Jacob continues to recalibrate the device. Meanwhile, Daniel remains a prisoner of Replicator Carter, who probes his mind to assimilate the knowledge of the Ancients. However, as she accesses his subconscious, he begins to access hers, and she struggles to maintain control as her brethren sweep across the galaxy. Replicators invade the SGC, and O'Neill orders the evacuation and destruction of the base.

As Replicators overwhelm the SGC and Dakara, Daniel reaches inside the mind of Replicator Carter and gains control. For an instant, every Replicator is held motionless, allowing time for Jacob to complete the recalibration of the weapon. To release his grip, Replicator Carter stabs Daniel in the heart, and as he slowly dies, the Replicators resume their invasion. Jacob activates the weapon, and a wave of energy translates through every stargate in the network. Instantly, Replicators across the galaxy disintegrate. The Replicators have been defeated, and the Goa'uld retreat. However, Daniel has vanished in a brilliant flash of light, his fate unknown. This episode aired in two parts.

Replicator Carter


  • Because of the Replicator attack on the Goa'uld, the ranks of the Jaffa rebellion are re-pledging their loyalty to the Goa'uld in the thousands. They believe the Replicators are a plague, an evil punishment brought upon all for daring to stray in their beliefs and betray their gods.
  • Dakara is deep within Ba'al's territory. The temple at Dakara is sacred to all Jaffa. Legend tells it is the place where Anubis rose from the dead. It is also the site of the first prim'ta ritual, the rite of passage that has bonded the Jaffa in servitude ever since. For thousands of years, the Jaffa have viewed Dakara as the holiest of sites, the very cradle of their existence. It is the place where the Goa'uld first gave the Jaffa their strength and longevity. Seizing control of the temple would prove beyond a shadow of a doubt that the Goa'uld do not possess the power of the gods.
  • Tolok wears the tattoo of Heru'ur. Aron wears the tattoo of Moloc.
  • The monument on Dakara holds a weapon that was built by the Ancients. It is the one weapon in the galaxy capable of destroying the Replicators, and will destroy all life in the galaxy as well. Only Anubis could survive such pervasive devastation.
  • The Dakara weapon uses an energy wave to reduce all matter to its basic molecular elements, in much the same way as the disruptor technology works on the Replicators, by separating the individual components. Once the frequency spectrum of the weapon matched the output of the disruptor to within a margin of .76%, the device became effective only against the Replicators.
  • The Ancient writings translated to "Midday the darkness is high in the sky. The wind blows on the pillow. Three days to the chicken" until the circles were rotated in the proper sequence.
  • Both Carter and Jacob have an ability to translate Ancient writings using Daniel's notes for reference.
  • Daniel had begun to access the knowledge of the Ancients locked in his subconscious.
  • At the battle of Dakara, the entire force of the Rebel Jaffa amounted to five ha'tak, eight alkesh, and ten squadrons of gliders.


  • Teal'c, the odds are not in our favor. [Daniel]
    They never are, Daniel Jackson. [Teal'c]
  • Hi? Hello, how are you, long time no see, what's doing, what's up, hey buddy...? [O'Neill]
  • You said we had a "problem," not a big galactic emergency. [O'Neill]
  • My relationship with the Council is still a little strained. [Jacob]
    It's not going to get any better if you keep stealing stuff. No complaints! I'll take anything I can get - weapons, receivers... silverware. [O'Neill]
  • And don't be afraid to remind him that we've saved his cute little gray bum several times. [O'Neill]
  • There's been a little chit, and chat, around the water cooler. [O'Neill]
  • You know that bitter taste in your throat, that's kind of wrapped around your uvula? That's what's left of your pride. [O'Neill]
  • I've got a better idea. Instead of helping you, why don't we sit back and watch you get your ass kicked? That way you'll be dead, and we'll be glad. [O'Neill]
    You cannot be serious. [Ba'al]
    Yes I can. I just choose not to. Some of the time. [O'Neill]
    With your insolence, you are dooming not just your world, but all of humanity. [Ba'al]
    I think big. [O'Neill]
  • I am so sorry. I was just finishing up a lovely brunch. [O'Neill]
    Impudence. [Ba'al]
    No, tuna. [O'Neill]
  • You know, you blow up one sun, and suddenly everyone expects you to walk on water... Next up, parting the Red Sea. [Carter]
  • General O'Neill built it using Ancient knowledge and an Asgard computer. [Carter]
    O'Neill? The mere thought of that makes me sick. [Ba'al]
  • It's a "blast door." [O'Neill]
  • I expect to be put in your will. [O'Neill]
    Already in it, Sir. [Siler]
    Okay, that's... weird. [O'Neill]
  • Good luck. [Ba'al]
    That was just creepy. [Jacob]
  • He sends us all his congratulations and says that he will drop by for a visit as soon as his consciousness has been downloaded from the ship's computer into a new body. [Carter]
    That just never gets old, does it? [O'Neill]
