Michael is sent on an unofficial mission to Tashkent, Uzbekistan to kill Kassim Tariq, the terrorist responsible for killing his family. Nikita arrives to assist Michael in the revenge mission. When Percy learns of this, he botches the operation by sending a team of agents, which leads to Kassim kidnapping Michael. Nikita eventually finds him, but Kassim has disappeared.
He learns Kassim is going to board a flight to Yemen, but when he tries to fulfil his revenge, Nikita, knowing Michael will die in the process and wants to save him, alerts the airport authorities to apprehend him. Meanwhile, Alex nearly blows her cover when she is caught snooping through medical files to obtain Michael's transmitter frequency. Alex blackmails Jaden into helping her. In the end, Michael returns to Division, and tells Percy he should have never trusted Nikita in the first place.
