One on One - S1.E22

Lambert soon exhibits signs of believing Sahmbi's story and understanding his motives, to the point where he seems ready to give Sahmbi his PPT.

But Sahmbi has the upper hand, with the mind controlling drug. Lambert starts questioning his mission, and distances himself from SELMA. Then Sahmbi orders Lambert to kill himself...
