Monroe reveals to Miles that everything he has ever done has been for Miles, as he has always followed him to have his back. In addition, he states that the war between him and Miles began when Miles attempted to kill him. Miles reveals that he could never kill Monroe as he still considers him his brother. He rescues Monroe from the new Monroe Republic, headed by Tom Neville. Meanwhile, Nora is shot in the abdomen while creating a way for Rachel, Charlie, and Aaron to reach Level 12, subsequently dying in Miles' arms. Aaron runs the shutdown command for the nanites, re-instating electric power worldwide. As the power is re-instated, the president of Georgia orders military strikes on Philadelphia, and lightning begins to strike the surface of the Earth at a rapid rate. However, the victory is short-lived as Randall appears and reveals he has been attempting to gain access to Level 12 for a long time, not to turn the power back on for everybody, but for the purpose of sending out ICBM's aimed at Atlanta and Philadelphia in order to reunite the states into one entity, quoting Lincoln's famous line, "A house divided against itself cannot stand." Randall then proceeds to say that everything he did was in order so that "this great nation shall not perish." When Rachel asks him why he is doing this, Randall smiles, calls himself a Patriot, and then takes his own life. At the end, the camera shows a room with an American flag, where someone is turning a lamp on and off. Another person enters the room saying that Flynn has succeeded in his mission, and that, "It's time to go home, Mr. President." The camera zooms out and the location is a U.S. Colony at Guantanamo Bay, where the President of the United States has presumably been hiding for the past 15 years, waiting for Flynn to fulfill his mission.
Flashbacks: Ten years after the blackout, Miles and Bass are in a restaurant reminiscing about their pasts. A rebel force attacks the restaurant, attempting to assassinate them. Bass retaliates by ordering the killing of the would-be assassin, along with his wife and children. This is the key factor that resulted in Nora and Miles defecting from the Monroe Republic.
