Ep 12. Bloodlines

SG-1 is called to a planet where they find a villager named Kar'yn waiting for them. She reveals that she is the daughter of Teal'c and that her people are in trouble due to an old Goa'uld named Heru'ur who is destroying their village and capturing their people for slave labor. Kar'yn begs Teal'c to come back with her and help her people.

Teal'c is hesitant, as he left his family behind when he defected from the Goa'uld, but the team convinces him to go with them. When they arrive on the planet, they discover that Heru'ur's forces have already taken most of the villagers captive. Teal'c, Kar'yn, and SG-1 begin a rescue mission to save the captives and take down Heru'ur's soldiers.

Upon reaching the village, they find that the children have been taken captive and are being held in a nearby pyramid. SG-1 goes to retrieve them while Teal'c and Kar'yn stay behind to distract the soldiers. Meanwhile, Major Carter is able to hack into the pyramid's security system and override the locks to free the children.

After rescuing the children and the remaining villagers, SG-1 and Teal'c launch a final attack on Heru'ur's forces. In the ensuing battle, Teal'c confronts one of his former Jaffa who is now working for Heru'ur. The two engage in a brutal fight, and the former Jaffa reveals that Teal'c's wife and son are still alive and living in hiding.

Teal'c is shaken by this news and decides to stay behind on the planet to search for his family. The rest of SG-1 reluctantly leaves without him, knowing that the search may take years.

Overall, "Bloodlines" is a strong episode that builds upon Teal'c's backstory while also showcasing the team's ability to work together in difficult situations. The action sequences are well-choreographed, and the episode's emotional moments add depth to the characters. Fans of the series will appreciate the exploration of Teal'c's past and the development of his relationships with the other members of SG-1.
