Ep 2. Seth

In Stargate SG1 season 3 episode 2, titled "Seth", the SG1 team discovers a cult of people who worship the ancient Egyptian god Seth. The team, consisting of Colonel O'Neill, Teal'c, Major Carter, and Dr. Jackson, are sent to investigate a suspicious energy reading on a distant planet. Upon arrival, they encounter a group of people who are under the leadership of a man claiming to be the god Seth.

The team soon realizes that this man is not actually a god, but rather an alien who has been masquerading as Seth for hundreds of years. He has been utilizing a substance called symbiotes, which allows him to control the minds of others and live forever. The team must find a way to stop him before he convinces his followers to do something catastrophic.

The team goes undercover to blend in with the cult and gain more information on their operations. They discover that the followers are gearing up to create a massive explosion that could destroy the Stargate on Earth. It is revealed that Seth's ultimate goal is to conquer Earth and rule as a god.

As the team gathers more information on Seth, they are met with resistance from his followers, who are willing to do whatever it takes to protect their leader. Teal'c, who has a history with the Goa'uld, tries to reason with Seth, but it becomes clear that he is too far gone.

Eventually, the SG1 team is able to neutralize the symbiotes and free the followers from Seth's control. The team apprehends Seth and stops the impending attack on Earth. However, the episode ends with a sense of unease as the team realizes that there are many more Goa'uld out there who could pose a similar threat.

Overall, "Seth" is a thrilling episode that showcases the dangers of blindly following a charismatic leader. It also delves deeper into the mythology of the show's central villains, the Goa'uld. The episode is a standout in the season and leaves the viewer on the edge of their seat until the very end.
