S9, E5: Because nothing but time will dissolve the link between them Daniel and Vala are forced to remain together at Stargate Command. But when Vala learns that P8X-412 is one of 43 planets already visited by a Prior of the Ori she persuades Mitchell to help the villagers of that primitive world resist this new danger. Mitchell Daniel and Teal'c accompany Vala to the planet where they discover the real reason for Vala's special interest: The villagers there worship her as the Goa'uld god Quetesh. Vala was once host to the real Quetesh and after she was freed of the symbiote she discovered that the people of this isolated planet hadn't heard that their god was dead. She continued posing as Quetesh and the villagers showered her with the few riches they had. Now she's back to collect her loot. She also thinks she can simply order the villagers to reject the Prior. Daniel and the rest of the team doubt that. The Prior's powers are very real - on his previous visit he apparently healed a villager Vachna of a terrible illness. Vala won't be able to compete with the Prior in a god-versus-god showdown; the villagers will inevitably lose faith in her and submit to the Ori. Daniel finally persuades Vala that their only hope is to tell the truth. If her people come to see Vala as a false god maybe they'll be suspicious of the Ori too. Unfortunately the revelation of Vala's true identity doesn't go over so well. The outraged villagers toss her in prison and put her on trial for her life. As Daniel argues that Vala deserves mercy the Prior of the Ori returns. He debates with Daniel and it's obvious that some of the villagers are buying his claims. When Vachna falls ill again however Vala heals him using a Goa'uld hand device. This demonstration forces many villagers including Vachna to question the validity of the Prior's claims - until more people collapse with the illness. The disease spreads too fast for Vala to keep up. Worse those she heals fall sick again afterwards. Soon even Mitchell succumbs.
