At the station, Edward responds to Armstrong's inquiry into why he didn't simply steal Marcoh's stone by replying that his conscience wouldn't allow him to take away the item that had healed so many of the townspeople, while Armstrong lets on that he does not plan to report Marcoh's whereabouts to his superiors. However, before they board their train, Marcoh himself appears and hands a small note to Edward. Having had a change of heart in regards to Ed's situation, he explains that what he has written down on the note is the place where his Philosopher's Stone research notes are hidden and that he believes Edward has the strength of will to look the horrible truth in the face as well as the talent to discover the "truth behind the truth". On the train, Edward tells the others that the note reads National Central Library, First Branch. Marcoh returns to his home to find Lust waiting for him.

In Resembool, the boys arrive at the Rockbell house and introduce Major Armstrong to Pinako and Winry. Winry angrily laments the complete destruction of her masterwork automail arm and wonders what kind of dangerous life the Elrics are living. Ed explains his situation and his hurry to return to Central and the Rockbells promise to have his arm fixed and his leg adjusted for his recent growth within three days. As Ed goes to visit his mother's grave, Pinako asks Major Armstrong to tell her how the boys have been getting on, as they neglect to send a single letter home. He explains that they are quite famous in the capital, but that their reputation tends to get them in a bit of trouble and asks Pinako if they are like family to her. She responds that she has known both boys since their birth and was a friend of their father, who had suddenly disappeared one day long ago. Armstrong asks what became of Winry's parents, to which Pinako responds that the both of them had gone to the front lines of the Ishval Civil War to serve as emergency surgeons and were killed in action. When it becomes apparent that the Elrics are staying at the Rockbell house even though they grew up in this town, Pinako reveals that Edward burned the Elric house to the ground on the day that he received his State Alchemist certification three years ago, so as to remove any path of retreat from his ultimate goal. For three days, Winry and Pinako set themselves to the task of machining and adjusting Ed's limbs and, once they are complete, begin the quick but painful task of connecting them to Edward's nervous system and adjusting them for use all the while listening to Ed gripe and dream about the day he will no longer require automail repairs. Winry tries to explain to Ed that his new arm is less durable than its predecessor, but Edward rushes off to repair Al's armor. Having collected all the broken pieces, Edward carefully transmutes them back into their proper shape, while being careful not to affect the area on which his brother's Blood Rune is drawn, as the rune itself is what keeps Al's soul transfixed to the steel. Ed declares that they will depart for Central at sunrise and as he sleeps, Alphonse thanks the Rockbells for their help on his brother's behalf. At dawn he next morning, the Elrics and Armstrong leave to catch the earliest train. Pinako asks them to come back for a visit if ever they desire a home-cooked meal and Winry, who is groggy from three days and two nights of labor, gives them a cheerful wave goodbye from her bedroom. However, that evening when she wakes from making up her lost sleep, she discovers a bolt that she had neglected to include in Edward's arm.
