S10, E17: The bombing massacre of a Jaffa leaders summit not only kills dozens of innocent Jaffa but also leaves Bra'Tac (Tony Amendola) clinging to life and Teal'c (Christopher Judge) badly injured. With his hands tied by the IOA General Landry is unable to give Teal'c the help he asks for to hunt down the man responsible. Teal'c believing the hypocritical IOA would not sit so idle if those dead had been humans takes it upon himself to leave SG-1 and hunt down the man responsible himself. Intel leads Teal'c to believe a Jaffa leader named Arkad is behind the bombing a step he took to try to control the Jaffa nation and deliver them to the Ori. Teal'c must wade through the seedy underworld from arms dealer to assasins to finally find the location of Arkad. With a history that runs deeper than just the battles they fought as opposing first primes Teal'c decides to take on the role of jury and executioner. SG Command meanwhile learns that the same Jaffa leader Teal'c is hunting appears to be coordinating a massive series of bombing attacks on earth as a pawn of the Ori. Not wanting to lose the only man who may know how to stop the plans that are already in motion SG-1 is ordered by the IOA to intercept Teal'c at all costs before he kills Arkad. The remaining members of SG-1 must decide between the life of their friend and the lives of millions at risk should the bombings succeed.
