Ep 15. Ethon

After a brief encounter on a planet with a young boy named Davos, SG-1 are getting ready to head back to Earth. However, they are interrupted by SG-3 who have been sent on a mission to destroy an Ori weapon on a planet known as P9C-882, or "Tegalus."

The leaders of Tegalus, Gerak and Oshu, call in SG-1 to try and negotiate a peace between the two nations on the planet before the weapon is launched, but it becomes clear that the mistrust and hatred between the two factions run deep.

Meanwhile, SG-3 begins their mission to destroy the weapon, but things take a turn for the worse when they are ambushed by a group of Jaffa and captured.

SG-1 must now navigate the complex political situation on Tegalus while also trying to rescue their fellow team members and stop the weapon from being launched, which could have devastating consequences not just for Tegalus but for the entire galaxy.
