Jok and Tarak have been rivals since childhood. They would steal from each other, lie about each other, and constantly tried to one up each other. They even took credit for things that the other one did. When Tarak went off and joined the Maquis, Jok joined Starfleet Intelligence. Today he is in Section 31 and has great power. He used his contacts to get Tarak’s crew to turn him in and he fixed the trial to get him sentenced to Denchar. He holds the rank of Captain in Starfleet but usually travels as a Lt. or Ensign.
