Last Stand

Plot
Osiris pulls a dagger on Daniel Jackson after finding him alone in Yu's quarters. Before she can do anything, he stabs her with the same device he used to modify Yu's memory, convincing her that he is Jarren, Yu's Lo'tar. It works, and she leaves, but not before he manages to point out that it is completely against the rules of the summit for her to possess any sort of weapon. He contacts Selmak again, and explains what just transpired. He has decided not to release the poison because he wishes to save Sarah. Selmak/Jacob reminds him of what is at stake, and tells him that he must release the poison immediately.

Meanwhile, the rest of SG-1 and Lt. Elliot/Lantash are still trapped in the Tok'ra's tunnels. Lantash tells them that they may be able to construct more tunnels if they can get their hands of some of the tunnel-building crystals in the lab. Teal'c and Jack O'Neill go to find the crystals, while Major Carter and Lt. Elliot, who is still too weak to walk on his own, remain where they were. O'Neill and Teal'c acquire the crystals, but are cut off by Jaffa. Another bombing run commences, and Major Carter and Lt. Elliot are trapped between two cave-ins.

Osiris addresses the System Lords, telling them how weakness is befalling them, and how they must join together, or be destroyed. Daniel is about to release the poison, when Osiris reveals to the System Lords that she has been sent by another Goa'uld&mdash;Anubis. The System Lords had believed Anubis dead, and though only Yu remains of the System Lords which banished and attempted to kill Anubis, they do not like the idea of allowing him to return. Osiris informs them that their only other option is to place themselves at the mercy of Anubis. Daniel reports back to Selmak, and they decide that releasing the poison would only accelerate the domination of Anubis, who was apparently one of the worst Goa'uld ever. Selmak tells Daniel that Anubis was "banished by the System Lords because his crimes were unspeakable even to the Goa'uld".

O'Neill and Teal'c manage to kill the Jaffa pinning them down, and return to where they left Carter and Elliot. When they arrive, they make radio contact, and Lantash tells them to use one of the crystals they have retrieved to make a short, straight tunnel which should connect their two tunnels. It works, and Teal'c seals the tunnel behind them. They continue creating tunnels and moving further away from the main base. Lt. Elliot tells them that the Tok'ra have broadcast a signal which will warn any potential rescuers to stay away from the planet; however, SG-1 decides to attempt to reprogram one of the signals to send an S.O.S. to Daniel and Selmak. They use one of the last crystals to get to the surface, and begin the 22 mile walk to the nearest broadcaster.

While walking through the space station in which the summit is taking place, Daniel finds a tank with a number of Goa'uld symbiotes inside. Later, Osiris meets in private with Yu, who is opposed to the idea of allowing Anubis back among the System Lords. Osiris tells Yu of her master's plan: since Anubis is not a System Lord, the Protected Planets Treaty does not affect him, nor does it require the System Lords to retaliate against him, a Goa'uld who is supposedly dead. He offers to destroy the Tau'ri as an offering to the System Lords, before joining their ranks. Daniel reports this information back to Selmak, and they realize that the Goa'uld are planning on making their human slaves into hosts as soon as the summit is over. Daniel decides to wait a little longer before making his escape.

Ba'al then opens a vote on whether or not to accept Anubis back, and the motion passes, 6-1, with only Yu opposing his return. Then, before continuing the summit meeting, they bring in the symbiotes. Instead of allowing them to blend with their slaves, they each take one, and they eat the symbiotes.

Later, Daniel has the opportunity to speak with one of the other System Lords's servants. He reveals that he too, knows the true nature of the Goa'uld. In fact, the Lo'tar enjoy their positions because of the hope that one day, if they have served their masters well, they will be granted the "honor" of implantation. As a result of this conversation, Daniel's fellow Lo'tar warns Yu that Daniel cannot be trusted. Meanwhile, Daniel is attempting to steal Yu's cargo ship, and leave with Osiris. He has learned of the attack on Revanna, the base of the Tok'ra, and communicates this information to Selmak. He manages to capture Osiris in the cargo ship, but is attacked by Yu. Yu releases Osiris, but she assumes that he is behind her capture and stabs him with her dagger. Before Osiris can kill Daniel, Yu gets up and begins wrestling with her for control of the dagger. Sarah takes over Osiris and begs Daniel to flee, still stalling Yu. Daniel escapes the cargo ship in an escape pod, and Selmak picks him up.

Daniel and Selmak arrive at Revanna, and cloak immediately after leaving hyperspace. Lord Zipacna, commander of the attack on Revanna, is, however, aware that a ship has entered the system. Daniel and Selmak receive the automatic warning telling them that the base has been compromised, and Jacob decides that they should leave. However, SG-1 finally make it to one of the broadcasters, and Jacob receives the S.O.S. They go in to land on the planet, and a number of gliders lock onto their heat signature as they enter the atmosphere. They take heavy damage, and they crash on the planet's surface, but SG-1 see the crash, and start off towards the downed cargo ship.

Daniel and Selmak leave the ship, which at this point is beyond a quick repair job. They meet up with SG-1, and they decide that their only chance is to escape through the stargate. Since Daniel still has the poison, O'Neill decides to take it with him, and once he gets near the stargate, release it into the atmosphere in the hope that it will kill all the Jaffa guarding the stargate. Teal'c does not think he can make it, but Lantash comes up with a different plan. He will take the poison from Daniel, and the others will hide. When the Jaffa find him, he will tell them that he knows how to synthesize the poison. When they take him to the base camp to teleport him up to the mothership, he will release the poison himself. Lantash and Elliot insists on the plan, as they are near death anyway, the others leave him to execute the plan.
