When people bash on Winry, it is probably this scene I think back to first. It’s so difficult for me to see how anyone could miss her strength or underestimate the pain she has gone through herself; a pain totally apart from the pain she feels for the Elric’s hardships. The loss of both of her innocent parents haunts her still at this young age, and when she feels this acceptance from a family that isn’t hers - to gain a sister she never had the chance to have herself - she feels an echo of that warmth that she had been missing.
Then it is taken away, yet again.
However, she keeps moving. Winry’s first moment of truth was in deciding not to pull the trigger in vengeance, despite her fears of losing her closest friends in the world. Her second, in healing her parents’ murderer and saving everyone to live another day, ultimately to even save the country.
Arakawa put a great deal of thought into Winry Rockbell; she’s a beautiful, dedicated, talented young woman who is not a fighter, per se, but is still absolutely integral to the heroes’ success. She is one of the creators of the world; the antithesis to the presence of destruction. She gives life back to those who have lost some of their own. Manifesting as part of the positive flow of the universe, acting as a single ‘One’ to contribute what she can to the ‘All.’ Without her, our hero lacks his own limbs to walk on, to fight with. Without innocent love to protect, there would be nothing worth fighting for.
