Line in the Sand

In an attempt to utilize Merlin's phase shifting technology, SG-1 answers the cry of a village pressured by Origin, and they attempt to phase shift the entire area. The plan appears to have been successful, until the device fails, and the Ori forces begin their onslaught. Meanwhile, Tomin, ordered to convert Vala to Origin, begins to question his faith in the religion when his views on the Ori's teachings clash with those of the Prior leading the assault, who's using the teachings to justify his actions.
