Mustang's unit was moved to the Easter Headquarters, so both Ed and Al were caught up with moving and other things. They had to go through all that not even a month ago, but no one was there to listen to their (mainly Ed's) complains.

"Niisan! Look what I…?"
Well, that day was one of those rare holidays the military had, and since it was a beautiful sunny day, Alphonse was out all day to have a walk. He also wanted to look around the new place they were in. He enjoyed the day very much, and as souvenir for his brother stuck in the dorm finishing some paper work, he found an interesting book on alchemy. But when he opened the door happily, he was greeted by an unusually sullen and grouchy face.
"Um…niisan? Did anything happen?"
Al said in a small voice, and glanced at the messy heap on his brother's desk. As far as he was concerned, Ed hadn't done anything since Al left. Then something caught Al's eye which made him extremely exasperated.
"What did Winry say in her letter?"
An opened letter. An unhappy Edward Elric. What other thing can this add up to except an undesirable word from Winry? He also noticed that the letter was redirected, meaning it was sent to Central once, so it arrived a little late. Which was probably another reason why Ed was in a bad mood.

Ed handed Al the letter without a word. Al took it, then he read it. Then he read it again, and again, and again. After re-reading about five times, he handed the letter back to Ed, clueless of what was going on.
"So…?"
"What do you mean, so?"
"…So why are you mad?"
Ed looked at his brother with disbelief. Al, on the other hand, just looked at Ed with a blank look. Ed sighed, and pointed to a line of the letter that literally ruined his day.

Lieutenant Colonel Mustang, huh? I remember him. He was good looking, actually.

"Oh. Now I get you."

Al said in a very exasperated voice. Ed, choosing to ignore that, started ranting.
"Of all the things she can say, she has to say this. Of all the people she can ever think is good looking, she thinks that damn bastard is good-looking. And…"
Al sighed as he listened to his brother's unreasonable complaints. First he started talking about how Mustang wasn't even good-looking, and how he was too old for Winry anyway. Next he started saying that all the people in the military weren't worth any good, and of all the people Mustang. Eventually, the topic shifted to how Ed wasn't short, he still didn't have his growth spurt yet, which was completely irrelevant to the primary topic.

When Ed was finally too tired to rant anymore, it was already getting dark.
"You know what, niisan?"
"What?"
Al smiled (in his mind), and then punched his brother's head without warning.
"OUCH! What was that for?"
Ed glared at him, but shut up when he glared even more to Ed.
"I personally think Mustang is better looking than you. But it is not as if Winry actually likes him, niisan. Come on! That is why you never grow up."
"Who are you calling so short that he can play hide and seek in a pile of sand?"
"I never said that. I mean, grow up emotionally. Goodness, niisan, I seriously wonder if you are supposed to be older than me."
Ed growled like one of those ill-tempered watch dogs, and burst out of the room. Al sighed at the childish behavior of his (supposedly) older brother, and watched his back disappear without a word.

Al picked up the book that he was supposed to give to Ed, and turned the first page. Though the content was far more complicated, it somehow reminded him of the first alchemy book he ever read with Ed. All those times in Resembool, their childhood…The things they missed, the things they were trying to get back. Al just wanted to get Ed's arm and leg back, but he knew that Ed wanted more than getting their original bodies back. He knew, that deep inside, Ed wanted to go back to Resembool. One day, when they regained everything, he wanted to go back. Back to Winry.

He thought it was interesting, in a way, that Ed got so jealous about Winry thinking Mustang as good looking. He never was aware before about how much Winry's words affected his brother's behavior. Well, now that he thought of it, it seemed as if every time Ed got into a fight when he was small, the reason was somehow related to Winry.

Al quietly smiled to himself when he noticed that Ed took Winry's letter with him. He stared out of the window, and saw the beautiful crescent moon. Somewhere under the same sky, his brother was writing a letter to Winry. Under the same sky, Winry was thinking about his brother. Both of them, under the same sky, watching the same moon.
"Since when did I become such a dreamer?"
He returned his gaze to the book, and only the sound of the turning of pages could be heard for the rest of the night.

Al never found out what Ed put in his letter for Winry…if he did write any, but Al was sure he did. It was fine with him, though, because Ed's actions spoke more than his words anyway.

xoxox

Winry,

Yeah, Al's fine. And Mustang is also doing fine (you know he is a colonel now?). And by the way, since we've been moved to the Eastern Headquarters, this is my new address. Don't send anything to Central anymore.

We were traveling to this town way, way East. With Al, of course. You know, I really hate Mustang! All the time there's a small problem or anything, really, he starts becoming all sarcastic. And I end up going to wherever the place is, and I have to be the one to get everything right. While he is comfortably sitting in the office.

We're having some crazy days…we were pretty surprised since when we arrived, we had to move straightaway. All the moving and everything stressed everyone up, plus I had to do some paper work because I screwed up in my last job. I mean I didn't screw up, but I didn't do it the way the military wanted me to. So I have to give in this report and written apology. So I'm going to be busy for a while. Might not be able to write back for a while, so sorry…in advanced.

Anyway, take care, and send my regards to bachan and Den.

Always,
Edward
