Crusade

Summary
A very pregnant Vala Mal Doran makes contact with Stargate Command, using the communication device Daniel and she used before (see "Avalon") and thus takes possession of Daniel's body. She tells the surprised SG-1 what happened to her after the events in "Beachhead". She has been thrown on an Ori homeworld in their galaxy by means she does not know about and awakened in the bed of the man who found her, who thought that she is a present from the gods. She learned that the town where he lives is one of dozens building ships and providing troops for the Ori invasion fleet. To stay undercover she decided to take a role as homemaker to the crippled Tomin, the man who found her. When she found out that she is pregnant she quickly marries Tomin to make him think it's his child. However Vala didn't know who the father really was since she had no relationship with anyone but later found out that the child is in fact "the will of the Ori."

Meanwhile on Earth Colonel Chekov informs General Landry that Russia has no interest in participating in the Stargate program, and plans to let their agreement with the United States expire. This means that Russia gets the Stargate back, as they had only loaned to the USA. Russia apparently has the backup of China on this move.

Back in the interrogation room, Vala tells the rest of SG-1 that she was suspected to be a unbeliever and was chained in public for three days by Seevis, the local administrator. Tomin rescued her without interference after this time. When she went by herself to see the ships built she was surprised by Seevis, who revealed himself to be the leader of the Anti-Ori underground movement. He plans to sabotage the ships to kill thousands of Ori followers.

In the mean time, on Earth, Landry finds out that the Russians do not really want their gate back, but are merely trying to coerce the US government. In exchange for the gate, the Americans are forced to give the next Daedalus-class battlecruiser under production (the third in the series after the Daedalus and Odyssey) to the Russians.

Meanwhile, on the Ori homeworld, Seevis' sabotage plan fails. The Ori send Tomin to kill Seevis. Tomin kills both him and Denya, and destroys the communication device, disrupting the communication from Vala. She is able to persuade Tomin that she was not part of the conspiracy, and that she will accompany him on his crusade against the nonbelievers. On Earth, the SGC does everything possible to find out where the Ori have built their second Supergate, and SG-1 decides to search for Merlin's weapon which is able to kill ascended beings. With the Ori gone, their followers will no longer see them as gods and the crusade would be unimportant.
