Voir Travelers, Season 2 - Episode 8

Three high-ranking Travelers are sent back by the Director to put Grace on trial for violating protocols, overwriting a person who was not assigned to be her host, and sabotaging the Grand Plan. Mac and the team must give testimony at the trial that will determine if she should be overwritten or not. Meanwhile, the Faction is trying to replenish its numbers by overwriting people with the stored minds in the Quantum Frame. It transpires the trial was staged by the Director to flush out a Faction member from within the three Travelers judging Grace, which it successfully does, this leading to Mac's team securing the Quantum Frame.
