Reckoning, Part 1

Plot
An unknown loyalist to Ba'al offers a "generous" term of surrender to the System Lords. The term is that the System Lords may continue to administer their domain, however they must pledge their allegiance to Ba'al. Suddenly, Sam is brought on board. She was captured by one of the sentries of the unknown Ba'al loyalist. Yu questions her. Suddenly, it is shown she is RepliCarter when her arm turns into a massive blade and she kills Yu. Then it goes to an external shot showing the Replicator ship approaching the System Lord's space station.

In the next scene a Ha'tak is in orbit, and on board on the Pel'tak level Teal'c and Bra'tac are commanding the vessel. They are soon joined by Sam and Daniel. They are accompanying Teal'c and Bra'tac as observers on one of the first formal attacks by the Rebel Jaffa. Sam "observes" that it may not be wise to continue without reinforcements, and Daniel remarks that this may lead to the death of the "observers". Yet Bra'tac and Teal'c contend that the effort is underway. The conversation is interrupted when another Ha'tak ship exits out of hyperspace. Teal'c begins the mission by transmitting the security code to confirm they are allies, in an attempt to get the other ship to lower their shields for boarding. However, the ship fires at the ship Teal'c is on and easily overwhelms their defense. Without weapons, shield, or engines Bra'tac, Daniel, Sam and Teal'c head for the level with transporter rings to ring down to the planet. As they proceed to that level they are caught by a horde of replicators. As they flee, Daniel is beamed away.

In the next scene, Jacob/Selmak arrives to inform Jack that the replicators will soon defeat the Goa'uld and then proceed to conquer the galaxy. In a laboratory, Jacob explains that the Tok'ra over the past few years have begun an effort to track the movement of as many Goa'uld mothership. This information is accessible on a secret subspace network. Jack is dismayed to learn such a thing existed, which highlights the on-going lack of trust between the supposed allies. By tapping into the network, it is revealed that the Goa'uld are losing countless battles across the galaxy.

The gravity of the situation is interrupted when an incoming wormhole is announced. Jack and Jacob leave the lab for the gate room. Bra'tac, Sam and Teal'c arrive. When Jack questions where Daniel was, Sam reveals that he was taken by the replicators. When asked why, she replies that Daniel was once ascended and may know a means of destroying the replicators (The weapon that was once effective against the replicators was of Ancient origins).

In a meeting Jacob reveals that the effort of the Rebel Jaffa movement was waning. Numerous Jaffa were re-pledging their loyalties back to Ba'al and other Goa'uld. Bra'tac reaffirms this statement stating that many Jaffa see the replicators as a plague unleashed by their "gods" as punishment for their betrayal. Later in that meeting, Sam informs the others that Thor hasn't had much luck in modifying the weapon that once was effective against the replicators. Sam will later be transported aboard Thor's ship to help in the effort to modify the weapon.

Meanwhile, Teal'c and Bra'tac discuss the critical situation of the rebellion movement. To restore the faith and momentum of the movement, Teal'c suggest taking the temple at Dakara. The temple is considered a holy site amongst Jaffa. It was there that the "gods" gave strength and longevity to the Jaffa and it is there that the Jaffa were bonded to eternal servitude. By capturing the temple, it will strike a blow to the image that the Gou'ald are gods. In agreement, both head to Jack's office to inform him of their plan to take the temple. Jack questions the simplicity of the plan. As Jack says, "There has to be a catch. Otherwise you guys would have done this a long time ago". It is revealed that under normal circumstances, the temple at Dakara is heavily fortified. However with the element of surprise and the fact that Ba'al is using his forces to counter the replicators, the planet should be relatively undefended.

The next scene shows Daniel trapped in the same prison that once held Sam. RepliCarter emerges and tells Daniel that he will be interrogated to obtain certain information. When Daniel says he will answer honestly to avoid the whole "hand-in-the-head" thing, RepliCarter replies it’s not a matter of honesty but rather that the information is buried in his subconscious.

On Chulak, Teal'c and Bra'tac persuade others of the rebellion leadership to attack the temple of Dakara. The others at first voice their doubts. However Bra'tac and Teal'c lay out their argument that with Ba'al distracted and the element of surprise the planet will be easily taken. Realizing a golden opportunity to deal a death blow to the Gou'ald stranglehold, the leadership agrees.

Back on Earth, Jacob is becoming concerned at the rate of conquest by the replicators. He suggests to Jack to inform Ba'al to change tactics, mainly retreat and stop aggressively attacking the replicators. Jack is wary of Jacob's suggestion, because it would mean that Ba'al would notice the attack on Dakara. Therefore, he will use his fleet to crush the attack and possibly kill Teal'c. The conversation is interrupted when an incoming wormhole is announced. Although no IDC is received, eventually a hologram with Ba'al appears. Ba'al wishes to ally with the Tau'ri, namely to get the weapon used against the replicators. Jack at first gloats over Ba'al's request, then flatly rejects it by stating, "Why don't we sit back, and watch while you get your ass kicked".

While the rebel Jaffa attacks Dakara, Daniel is strangely baffled to find himself in the same clothing and setting where he was first found in the start of Season 7. Oma appears before him telling him of the situation, and states she is there to guide him for ascension again.

On what seems to be Ba'al's homeworld, Ba'al approaches the throne room. On the throne is a sickly man with numerous lesions on his face and body. Ba'al gives a report on the current state of the war with the replicators, essentially he is losing. The man, a Goa'uld, retorts that Ba'al should not be concerned, and ask Ba'al to trust in him.

Later back at the SGC, Sam reports that she and Thor may have come up with a modification to the weapon allowing it to work again. She states that they need to do some battlefield testing. While Sam and Thor locate the nearest replicator infested ship, it is shown that the rebel Jaffa attack on Dakara was successful. They were able to capture the temple without much resistance. Thor has located a ship and fires the newly modified weapon. It cleanses the ship of the infestation. Another replicator-controlled ship arrives, and Thor fires on that ship. However, the replicators have adapted and so they flee into hyperspace.

Ba'al returns to the throne room and interrupts the Goa'uld, who is taking control of yet another host. When he is done, Ba'al informs him that the rebel Jaffa has taken Dakara. The Goa'uld grins and stated that he foresaw this. He knows that all the rebels are on the planet and know they are presented with the chance to once and for all destroy the rebellion.

Thor's ship has now been affected and in a valiant effort, transports Sam back on Earth and to force the ship as far away from Earth as possible. On Dakara, the rebellion learns that Ba'al has broken off contact with the replicators and is heading towards Dakara.

Back in Daniel's world, the discussion between Daniel and Oma ends when Daniel sees through RepliCarter's disguise. Knowing it was fruitless to continue, RepliCarter appears and informs Daniel that she has found it: a weapon built by the Ancients that is capable of killing her and the replicators. The weapon is on a planet named Dakara.

Back at the SGC, Siler and Walter are nervously hosting an unamused Ba'al, awaiting Jack. He informs Jack that he has learned of a weapon hidden on Dakara, and wants Jack to destroy it before he can claim it, because it is capable of destroying all life in the galaxy. There is someone who would use it, and would be capable of surviving the weapon&mdash;Anubis.
