Ep 3. Ascension

Stargate SG1 season 5 episode 3 titled "Ascension" follows the SG1 team as they visit the planet of the Nox, a group of peaceful and advanced beings. Their mission is to seek their help in a potential conflict with their allies, the Tollans, who have developed a powerful weapon that could threaten the stability of the galaxy.

As they arrive on the planet, they encounter Anteaus, a member of the Nox who informs them that their leader, Lya, has ascended to a higher plane of existence. However, he agrees to help them plead their case with the other Nox leaders.

Meanwhile, Daniel Jackson is struggling with the revelation that ascension is a real possibility and what it means for his own life. He becomes increasingly obsessed with the Nox's way of life and begins to question the morality of continuing to fight wars and kill other beings.

As the team meets with the Nox leaders, they learn that Lya's ascension may have been triggered by an encounter with Oma Desala, a powerful ascended being who has been known to influence other beings to ascend. This leads to a debate amongst SG1 on whether to pursue ascension or to continue to fight for their cause.

The situation becomes even more complicated when a group of rogue Jaffa attack the planet, seizing the Tollan weapon and threatening to use it against their enemies. The SG1 team must work with the Nox to stop them and prevent further bloodshed. This also leads to a final confrontation between Daniel and Anteaus where they must confront their beliefs and their place in the world.

Overall, Stargate SG1 season 5 episode 3 delves into deeper philosophical and moral issues that have been present throughout the series. It also introduces new elements to the show's mythology and provides insight into the cultures and beliefs of other beings in the galaxy.
