Aaron, Nora, and Charlie are captured while hiding at the home of a friend of Miles after the four infiltrate Philadelphia. Miles takes Neville's wife Julia hostage and exchanges her for their safe return. Neville returns Aaron and Nora, and directs Miles to a defunct power plant where Charlie and Danny have been taken. Charlie reunites with her mother, Rachel, and her brother, Danny, at the plant. Rachel successfully completes the pendant amplifier before killing Strausser when he attempts to assault her. As Miles and Nora rescue Danny and Charlie, Miles faces off with Monroe to give the others time to escape. Monroe forgives Miles' treachery and pleads with him to come back and join his side, just as in Miles' hallucination. However, Miles refuses and fights with Monroe, and Miles then makes a quick exit when Monroe's soldiers appear. All of them escape after Aaron blasts a hole in the exterior wall with Nora's pipe bombs, but stop in their tracks when they hear a thundering sound and see a militia helicopter take flight using Rachel's amplifier and spool its minigun.
Flashbacks: The life-long friendship of Miles Matheson and Sebastian Monroe is explored in a series of flashbacks working backward through time. Five years after the blackout, Miles and Sebastian are fighting in "The Trenton Campaign". Miles is injured and wants Sebastian to lead the troops. Sebastian doesn't leave his side and pledges his life to Miles. During the next flashback, two years before the blackout, Miles finds Sebastian, who is drinking and completely depressed near four freshly dug graves that belong to his parents and two sisters, who were recently killed in an accident. Miles talks Sebastian out of suicide and into giving up his gun to him. During the next flashback, both of them are playing together as kids. The origin of the "M" insignia, the mark of the Monroe Republic, is revealed as a childhood symbol of unity standing for both "Matheson" and "Monroe".
