Fair Game

S3 E3: Asgard leader Thor tells Col. Jack O'Neill that the Goa'uld system lords plan to attack Earth. He offers his help in negotiating a peace treaty. Three system lords attend the summit: Yu Nirrti and Cronus ΓÇö the Goa'uld lord responsible for killing Teal'c's father. The three initially agree to the Asgardian peace proposal on the condition that Earth surrenders its stargate. When Teal'c and Cronus are discovered unconscious and both badly beaten Teal'c is blamed and the two remaining system lords vow to attack Earth as retribution. Despite Nirrti's claim that she tried the healing-hand technique on Cronus and it didn't work Maj. Samantha Carter (who just prior to this mission was promoted from captain) convinces Yu to use it and in so doing saves Cronus. Realizing that Nirrti orchestrated the beating to seize power Yu and Cronus turn their rage toward their former comrade giving Earth a temporary reprieve.
