Heiderich may not be Ed and Al's brother, but he really was like a brother to Ed! He really looked like Al, but at the same time, I sort of thought he was like a male version of Winry. You know, light blonde hair, blue eyes, obsessed with machines and whatnot. It could work! But I was happy with his role in the movie, though I still wish he'd lived.
I'm also still switching from style to style... hahaha... I don't think I'll ever pick just one.
