[edit] Plot

Spoiler warning: Plot and/or ending details follow.

[edit] Part 1

Colonel Barnes and Lieutenant Fisher return from an undercover mission to another planet that has fallen to the Ori.

Colonel Samantha Carter proposes creating a machine that will emit a field that will cancel out the powers of a Prior. She and Dr. Lee begin to work on the machine.

Gerak is visited by a Prior on Dakara. He tells him that he has read in the Book of Origin, and he becomes convinced that the Ori are the gods they've been searching for. He sets out to make all Jaffa bow to the Ori as gods. Gerak then presents his beliefs to the Jaffa High Council and several of them are interested. Teal'c and Bra'tac discuss this after the meeting and they decide to oppose Gerak's vision. However after some time the council agrees to legislate Origin.

Lieutenant Fisher returns to Earth as a carrier of the Prior Plague, which appears to be both airborne and persistent. When he listens to a speech of General Hammond at an Air Force base he is taken captive and brought back to SGC. At the base he reveals that he was 'blessed' by a Prior during a Prostration, who seemingly was aware that he was from Earth. Also because he is the carrier of the plague he isn't sick. However the plague begins to spread wildly throughout the country, until the President of the United States is forced to put the entire nation under quarantine.

While Carter is still working on the device, a young boy suddenly appears. It's Orlin, an Ancient who returned to make some startling revelations about the Ori and their true intentions. He reveals that the Ori won't give the secret of Ascension to their followers. Instead they suck the life force from them which gives them more power. Not wanting the Ori to gain control of the Milky Way Galaxy, he descended yet again to help Carter find a cure.

Orlin then starts to work on a cure but during a lunch (where he also reveals that he still has feelings for Carter) it becomes clear that he starts to lose what is left from his ancient knowledge. However he finds out that that they will need the blood of the Prior who infected patient zero. Capturing him may be more difficult than anything SG-1 has ever done before. However the weapon of Carter and Lee is finally completed and thus Col. Mitchell and Jackson lead a team to capture the Prior.

On Dakara a Prior visits Gerak and tells him to go to Chulak to convert the population to Origin and he agrees to do so. However in the end he can't bring himself to follow the order. The Prior is angry and thus takes him to Celestis to meet the Doci. There, he is turned into a Prior of the Ori and returns more powerful than ever.

[edit] Part 2

Gerak tries to convince the Jaffa council to follow the Ori as a Prior now. However Teal'c plans to fight against him on Chulak. Col. Mitchell and his team prepare to stop the Prior on the Sodan's homeworld. There, Lord Haikon reveals that he and the rest of the Sodan have renounced Origin, having been ordered to slaughter a community of simple farmers who rejected the Ori, and having found that another civilization who rejected the Ori was wiped out by a plague. The Sodan agree to help SG-1 capture the Prior, who was the one to start the plague on Earth, by using the new device Dr. Lee and Carter constructed. Once the Prior arrives, SG-1 and SG-22 manage to find the right frequency, stunning the Prior who is surprised that his powers are gone and extracting the blood sample Orlin needs to finish the cure.

Meanwhile, Teal'c tries to stop Gerak by amassing a fleet of those who are not willing to follow the Ori. When Gerak encounters them with a larger fleet, they both teleport to Chulak where Teal'c manages to appeal to Gerak's still-Jaffa side to stop following the Ori, as the two of them visit the site of the battle where Gerak's father fell in the fight to free all Jaffa. At the same time, General Landry visits the planet where the Prior was captured, with Orlin - who reveals to him the true nature of the Ori and supports his assertions by revealing parts of the Prior's past: his name Damaris and the names of his family. The Prior however, cannot be convinced to abandon the Ori. He begins quoting the Book of Origin and tries to capture Gen. Landry using his powers only to be shot by Col. Mitchell. However, the Prior was able to infect Landry with the plague. Orlin also tells them that the Prior has revealed why the Ori are coming to the Milky Way—they're coming to destroy the Ancients.

Back on Earth, Gerak goes into the SGC infirmary, but hesitates to use his powers. When Teal'c asks him why he hesitates, he admits that he shall die for helping them, but proclaims that he shall die free. Using his powers, Gerak heals all infected with the plague in the SGC, but then instantly bursts into flames; evidently, the Ori include a 'fail safe' in their Priors should the Prior turn against them. Dr. Lam is able to isolate an antibody from those healed with the help of Orlin's previous work. The plague that has reached most of the world at this point is successfully stopped, with casualties estimated at about 3000 people.

The episode ends with Orlin becoming a normal human being with possible brain damage and with no memories at all. He is confined to a mental hospital.
