to avenge them personally, suspecting the honor-less, ambitious warrior Arkad; General Landry refuses to sanction a killing mission without solid proof, but cannot stop Teal\’c going it alone. Bra\’tac explains to Daniel Arkad\’s sinister past, probably even murdering Teal\’c mother. Information from resistance on another planet indicates Arkad is in league with the Ori and a plan to attack Earth. Arkad comes meet General Landry, offering to help defend Earth against the Ori, denying any part in the bombings, while defending Origin, incriminating a Jaffa sect.
