After a four year absence, Ed and Al finally return to their childhood home of Rizenbul.

Inside Pinako's auto-mail shop, Winry is shocked to find that Ed's auto-mail arm has been completely destroyed. Winry scolds the two for doing things that are dangerous. Upon inspection, a new arm must be constructed and adjustments must be made to the leg. Because they are in a hurry, Pinako promises to have everything done in three days.

While Ed and Al relax outside, Armstrong, Pinako, and Winry busy themselves with repairs. Pinako asks Armstrong about the life the two brothers lead, and he explains that they sometimes get in trouble because they are so famous in Central City.

With the free time they have, Al convinces Ed to visit the grave of their mother.

Back at the shop, Al and Winry talk about old times. However, Al seems to have lost parts of his memory.

That night, while Winry is taking measurements of Ed, she happens upon Ed's silver pocket watch. Enchanted by it, she begs him to let her take it apart but he sternly refuses despite her pleas.

Ed enters their bedroom only to find Al sulking on the bed. His fuzzy memory is causing him to worry about his past. Suddenly, Ed wishes to ask Al a question he has been holding back for some time but holds off on it. Armstrong enters, breaking the tense mood, asking the brothers to enjoy and appreciate what Rizenbul has to offer.

Three days have passed and it is time to connect Ed's auto-mail parts. Ed, although having gone though this many times, is temporarily incapacitated by the pain of reconnecting the nerves. Soon after, Ed is back on his feet and fixes Al's armor body right away. With both brothers back in shape, Ed and Al spar to train their bodies in addition to their minds. Later on, Armstrong joins them.

While they are sparring, Winry can no longer resist and goes to examine Ed's watch. However, she is halted when she opens the cover of the watch. Upon returning it, she cries for Ed and Al because they can no longer cry and tells Ed that he does have a family to go back to, Winry and Pinako.

Before dinner, Ed and Al have gone off somewhere. Worried, Winry heads upstairs and blinks a lamp just like what their mother did when they were children. On their way back from visiting their old home, they find a blinking lamp just like when they were children.

On the day of their departure, Winry wishes the party a save trip. She tells Pinako that the date Ed and Al burned down their house and left was carved into Ed's pocket watch.
