The three of them had always been inseperable. Since the moment they were all introduced as small children, Edward, Winry, and Alphonse had formed an unbreakable bond. They shared everything together. The happy times as well as the sad ones. Their parents and their shared Granny couldn't help but smile at seeing the three always playing together in the vast fields of Risembool.
After Hohenheim left, Winry comforted the boys - even though Ed huffed and swore he didn't care. With the passing of Trisha, their beloved mother, they held hands as they stood with Pinako in front of her grave. When news came that Winry's parents had been killed in the war in Ishval, the Elric brothers ran down the hill and forced her to play with them; both of them hated to see her cry.
Then that fateful night when they tried to bring their mother back..the night they thought everything had been lost due to their sins..they only wished they could forget the gruesome thing that they brought back and forget the precious pieces of their beings they had lost in exchange.
For a long time, the bad times seemed to outweigh the good. The three had suffered such great tragedies and losses, most of which before they were even teenagers. And now, years later as they all sat atop a hill, having a slice of Winry's now famous apple pie, they smiled looking back. Sure, they had suffered. Sure, they had each thought there was no way things would get any better - no way they could move forward.
What they couldn't see then, however, was that they had made it through everything together. And oh, what a blessing that had been and would always be.
