Reckoning, Part 2

Plot
Sam and Jacob get inside the Temple, and find the Dakara Superweapon. They quickly realize that it can be reprogrammed to disrupt any specific type of matter, rather than just everything. Sam realizes that if she changes its wave-output to match that of an enhanced Replicator Disruptor, the weapon can be used to destroy every Replicator in the galaxy simultaneously, giving them no time to adapt. However, to extend the blast-radius of the Weapon to encompass the entire galaxy, they will have to reprogram the Dakara Stargate to dial out to every other Stargate in the galaxy. This is a feat that they know Ba'al is probably capable of (having demonstrated extensive knowledge of the workings of the Stargate network in "Avenger 2.0").

Sam relays her plans to Teal'c, and Teal'c contacts Ba'al. Ba'al refuses to listen, but Teal'c explains the situation anyway. He merely asks that Ba'al slow down his approach towards Dakara to allow Sam time to realign the Superweapon to destroy all the Replicators, which will defeat a common enemy.

Ba'al uses the Goa'uld hologram communication device to appear inside the temple next to Sam, and she, Jacob (grudgingly) and Ba'al work together to try to make the device work. Ba'al will reprogram the Stargate. They have to change the weapon's wave-pattern to resemble that of the Replicator Disruptor to within a degree of 0.76, and the difference is currently large. A random suggestion by Ba'al improves the situation, prompting him to state "I am a god. Gods are all-knowing."

Time is running out. RepliCarter is still probing Daniel Jackson's mind because she wants to assimilate all the Ascended knowledge it contains. However, there is too much there, and it strains the entire Replicator army to hold even a portion of it. It is infinite knowledge, "all the knowledge and power of the universe."

At the same time, however, RepliCarter goes against her word and attacks the SGC. Replicators begin to flood the place. The mountain goes into full alert, with Jack being backed into a corner as the Replicators take over the base. He and the few who haven't gotten out are now desperately fighting for their lives. Cut off from the surface and with the base set to be nuked, they try to escape through the Stargate, but Siler has trouble trying to dial out due to the Replicators' attempts to gain control of the control systems.

The Replicators land on Dakara and begin flooding into it. They know they are in danger. Sam desperately tries to finish aligning the weapon.

In the meantime, Daniel has used the link between his and RepliCarter's mind to secretly probe back into her mind all this time. Suddenly RepliCarter realizes he has done this and breaks the link - but it is too late. They engage in an impossible mental battle. Daniel attempts to control the entire Replicator army, to stop them, but it is too much for his mind to handle, there are too many of them.

Daniel succeeds in freezing every Replicator in the galaxy for a few moments. This gives Jacob enough time to get the Dakara Superweapon to within an acceptable margin of the wave-pattern with the Disruptor, and he sets it off. It slowly rises out of the mountain and charges up. Now they can only pray it will work, as Daniel loses control of the Replicators, they spring back into attack, RepliCarter breaks free of Daniel's mental grip, and stabs him.

Ba'al dials every other gate in the galaxy, and every shot of every gate opening is replayed. In the last moments, Sam is with a last fight machine-gunning the Replicators that are only meters away, Teal'c is fighting beside her, O'Neill is defending himself in a corner as the Replicators swarm the remaining portions of the SGC, and Daniel drops to the floor, dead.

Then the Dakara Superweapon blasts, and a bubble of light explodes from the mountain-top, passes through the gate, and shoots through the galaxy. Every replicator everywhere is destroyed, including RepliCarter, at the last. All is saved.

Ba'al laughs. Now that the Replicators are gone, he is free to take back Dakara. However, not all has gone to his plan. Rebel Jaffa had board his ship and had him surrounded. None of his subjects any longer sees him as a god. They make to kill him, but he escapes, inexplicably, by the use of an Asgard transport beam.

The Jaffa Rebellion has succeeded, and they make the Temple of Dakara the center of their new Free Jaffa Nation. Jaffa loyal to the System Lords had all come together to help. The SGC receives a message that Thor had survived by transferring his mind to his ship's computer and was ready to get in a clone body. Yet Carter and O'Neill can't help but wonder about what happened to Daniel.
