When Cary Agos was arrested
After Cary was charged with conspiracy to traffic drugs, he turned to Kalinda for help. She made an arrangement with Lemond Bishop: He would provide protection for Cary inside prison in exchange for a huge favor to be named. After handing her a cellphone so that he could reach her for whatever he might need, Lemond let it slip that the real perpetrator was trying to export drugs to Toronto through Chicago.
