He tries to talk Sonya into another plan, but isn't successful. Michael then reaches out to Strong for a way out. Surprisingly, Strong supports the mission and tells Michael to go through with killing Steele. Michael and Sonya's first attempt fails due to a signal jammer preventing their planned explosion. In the end, Michael is forced to use a sniper rifle to take out his friend.
Meanwhile, Fiona helps Carlos deal with troubles from his past. He ratted out a gangster who was sent to jail. When the gangster got out early, he wanted revenge on Carlos. Fiona helps Carlos escape capture and then find a witness that could put the gangster behind bars again. When Carlos meets with the cop, he's double-crossed. She gets killed and he is captured. Fiona calls Michael to help free Carlos. Michael pretends to be the witness and calls on Sonya's contacts to get a Colombia drug supplier to put an end to the hit on Carlos.
