Toward the end of series 6, Adam and Jo attempt to infiltrate a dangerous gang, the Redbacks. However their infiltration ultimately proves unsuccessful, and the pair are captured and imprisoned. Having already been raped and tortured by Bochard and afraid that she will not be able to withstand further torture, Jo begs for Adam to kill her so that she will not divulge classified information. The episode concludes with Special Forces storming the building, only to find Adam sitting silently as he cradles an apparently lifeless Jo in his lap.
