The Elric brothers were now walking through the city. Edward was clearly a bit irritated, complaining and venting about Colonel Mustang, as he did every time he ended a meeting with him. Alphonse was walking beside him, listening to all of his older brother's angry rant

Edward: He thinks he's better than us. He's nothing but a coward! He says, kicking a rock in his way and putting his hands in his pockets

Alphonse: Don't get so mad brother... Don't mind him, he's just doing his job,,
