Alphonse is lagging behind, seeming to walk slower every minute, even though just yesterday he had been able to sprint faster than Edward.
This isn't going to work, brother. he says, when Edward stops, staying a good distance away from Al. There is something weak and distant about his voice that worries Ed.
Ed looks away. I'm going to get your body back.
It won't work. Trust me, brother, just trust me. I know. This time Al is the one to turn away. But I wish I didn't.
Later, when Edward is alone, he wishes that he had listened.
