Family (S02E08)

Teal'c's mentor, Bra'tac, arrives unexpectedly through the stargate with shocking news: The Goa'uld system lord Apophis survived the destruction of his ship and has kidnapped Teal'c's son, Rya'c. Col. Jack O'Neill and the rest of the SG-1 team agree to join Teal'c as he returns to Chulak to rescue Rya'c, but when they arrive they find much has changed. Because Teal'c didn't return from Earth, his wife, Drey'auc, assumed he was dead and married his old friend, Fro'tak. To make matters worse, Rya'c has been brainwashed by Apophis into denouncing his father as a traitor, and he foils the team's attempts to rescue him. Meanwhile, Fro'tak becomes jealous after seeing Teal'c and Drey'auc rekindling their marital flame. Consequently, when the team is almost captured, Fro'tak attempts to betray them to Apophis, forcing O'Neill to take drastic action. Teal'c sees a glimmer of hope when Rya'c conceals a friendly message in his denunciation of him. Teal'c becomes adamant in his desire to rescue Rya'c and take him back to Earth. Although O'Neill sympathizes with Teal'c, he suspects that Rya'c — or his controller, Apophis — might be setting an elaborate and deadly trap. (Metro-Goldwyn-Mayer (MGM))
