Mustang's got a sister!

Summary- When the Elric brothers get called back to mustang he decides to call in some help, the Lightning alchemist, to watch over the boys and help with their research. But Full metal and Lightning don't seem to get along when Ed finds out who Lightning really is. But things change over time when Ed's feelings take a turn for the better.

Once again Ed and Al get called into Mustang's office. It seems that the Elric brothers are having trouble with their research and keeping out of scars path. The military are also having trouble keeping the boys in their sight since they have a tendency to run off without letting the military know where there going and when they'll be back.

Mustang wasn't too happy about the boys not reporting to him about what they have discovered their location, or any trouble they may be in.

"Ok it seems you two are having trouble with your research on the philosophers stone." Mustang said to the boys that were sitting on the couch in front of him. "And you keep running off from military protection and you can't keep doing that Edward, not while scar is still on the loose. We can't afford to lose on of our better state alchemist if we want to capture him."

"Yeah, yeah so why did you call us here? We have things to do." Ed said in an aggravated tone because he was mad the Mustang called him and Al there in the first place.

Since he never liked hearing Mustang nag on them.

"You're here to meet the new person I have to watch over you boys." Mustang said while walking over to the door and opening it "Come in lightning and meet your new assignment."

The brothers stood up and turned around to be faced with a blond hair, blue eyed girl.

"Ed, Al this is the lightning alchemist she will be traveling with you, reporting to me on your events and helping you with your research. And there are no worries about her falling behind cause she is a alchemist."

"WHAT! You expect us to have a girl hound us every where we go!" Ed shouted

"Brother! She could help us." Al said

"Alright I guess we could give this a try but I'm not saying I like this."

"Now lightning if these boys are seriously injured it will be your state certification as an alchemist." Mustang said.

" WHAT you can't be serious!" Lightning said

"Yes I am very serious now on your way." Mustang said pushing them out the door.

Lightning let out an irritated sigh as they stepped out side thinking of heading for Central even with the incident that happened in laboratory five a year ago.

"Ok listen I have one thing if I have to look after you two and that's if you don't tell Mustang what I do and I wont tell Mustang the little details that we do, as in any trouble we come across or any unexpected travels we have to do. Deal?" Ed and Al looked at each other and shook their heads.

"Deal." Ed and Al said. "Oh and by the way just call me Ed and this is Al"

"I'm Lori" they were all about to head towards the train station when Lieutenant Colonel Hughes came walking by.

" Well, well, well I see that your brother already assigned you the these two." Hughes said. And Ed and Al turned to Lori.

"BROTHER? Mustang's your brother?" Ed said shocked. "Ok no way is Mustang's sister staying with us there's no way I'm going to let this happen!"

" I might be Mustang's sister but I'm nothing like him, I mean the only difference between us physically is our hair color, sure. But I am nothing like him; he wears the uniforms I don't. We are two totally different people and I don't like this idea any more than you do Ed but I have to in order to keep my state certification as an alchemist, I've worked too hard and too long to lose it now." Lori said getting slightly irritated by Ed's cocky attitude.

"What do you mean by worked to hard and to long?" Ed asked his voice losing volume.

"Nothing forget I mentioned it." Lori said closing her eyes she gave a sigh "Well we should get going if we want to catch the train to Central." she saluted to Lieutenant Colonel Hughes and started walking. Ed and Al looked to Hughes as if looking for an explanation for the sudden change in attitude from their new watchdog.

"Don't worry about it, she's just had a rough past if she wants you to know she'll tell you." Hughes said "Well you better get going before she leaves you all."

"Yeah lets get going." Ed said while throwing his fist into the air. 'I wonder if I can get anything out of what happened to her, and how long has she been an alchemist. She doesn't look any older than me, well I guess I'll find out'.

Ed and Al ran to catch up to Lori who was way ahead of them.

"So Lori," Al spoke up trying to start a friendly conversation "How old are you?"

"I'm 16." She said while putting her hands into the pockets of her jeans. "And if I'm right I'm guessing Ed's 16 too, right?"

"Yeah I'm 16 and Al's just two years younger than me"

"Wow really I would have guess two years older since he's way taller than you" Al couldn't help but laugh at the look on his brothers face when she said that.

"Yeah well that's because he's in that armor and besides you have no room to talk I'm just as tall as you are" Ed said defensively while sticking his tongue out at her.

"Yes well I'm the height of an average girl, so that means you're the height of an average girl and most guys are at least three inches taller than the girls."

Ed let out an irritated growl 'I don't think I'm going to be able to put up with her, she's to much like Winry, Winry….' after that Ed got unusually quite after his last thought cause he was thinking of the last letter Winry sent him he was pretty depressed for a while after that from what she said about shes tired of waiting for him.

'Dear Edward,

I just wrote this letter to tell you that I am giving up on you Ed, as in I loved you once but that time has gone and passed. I am tired of worrying so much about you and your brother. You two go three to four months at a time without a single letter or phone call letting me and granny know that you are still alive and personally I can't take it any more so that's it. I am giving up on you, we can still be friendsbut nothing more. And I will still be your automail mechanic, I have come up with a new design that should last a while if you don't abuse it.

So goodbye for now Winry R.

Before Ed knew it they were at the train station getting readyfor the train that was supposed to be there any minute. Lori looked over at Ed and it looked as though he was deep in thought.

Al looked at his brother and knew what he was thinking about, he to wondered why Winry never told Ed how she felt so maybe he would call or write more letters and come around more. And before the three knew it the train had come to a stop and they boarded silently onto the train and into their seats.
