A/N: Read, Review, Favorite, and Follow

Yang walked through the doorway to HQ With a wide smile on his face. Greeting everyone he saw with a wide smile. Getting confused looks and reluctant hello's back. Not noticing every ones confusion he continued down the hall to Colonel Mustangs office to turn in his report. Yin making sure to follow in secret.

Yin couldn't help but shake his head at how much Yang acted nothing like Edward without him. He would have to teach him a few things when they are alone again. If he keeps this behavior up some one's going to figure them out sooner or later. More likely sooner rather than later. When they finally made it to the office Yin was unable to follow inside without getting caught.

Line Break

The first thing that tip Mustang off that something was wrong was when Edward nocked before entering his office instead of kicking down the door like usual. He won't even have guessed it was him if it wasn't for his voice on the other side of the door.

"Requesting entrance Colonel Mustang." Edward's voice could be heard saying from the other side of the door. Mustang raised an eyebrow at the sound. Kind of unsure how to handle this type of situation Mustang simply said "Come in Fullmetal.".

Once he was inside Yang gave a salute that had everyone tilting their heads in confusion. "Reporting in Colonel Mustang. I have my report ready for you." Yang said placing the folder on his desk. Yin who was had his ear to the door slapped his hand against his forehead as he shook it back and forth. Not believing Yang could be such a bad Edward without him. Yin knew he played a hug role in Edwards personality, but so did Yang! He should be a much better Edward then this.

Mustang looked behind Edward to Alphonse everyone following his example. Alphonse simply shrugged his shoulders indicating he had no idea what was wrong with Edward either. Mustang turned back to Ed who was still saluting waiting for the approved okay he could stop.

Mustang realizing this told him he could stop. Yang suddenly got a mental message from Yin to meet him in the bathroom. "Permission to leave for a few minutes sir?" Yang ask Mustang. Mustang gave him a flabbergasted (Couldn't think of a better word) look. "Ummm... Sure? Since when do you ask me to leave? Go ahead if you'll be back In a few minutes." Mustang stated.

Yang nodded in thanks before leaving the room. He made his way down the hallway were the nearest bathroom was. When he entered he was pulled in quickly and the door was quickly slammed and locked shut. "What the hell was that?!" Yin yelled. Yang covered his ears at the sudden unexpectedly loud sound. "What was what?" Yang ask not understanding what he was talking about.

"That little performance back there! You call that acting!" Yin yelled. Yang shrinked back with a childish pout on his lips. "I thought I made a good solider." Yang huffed out. Yin groaned "Your not supposed to be a good soldier! Your supposed to be Edward!".

"From now on I will tell you what to say and do through our mental link. You must follow it to the T. Understand." Yin directed. "Yeah." Yang said dejectedly.

(Back at the office)

"Okay who the hell was that? Because there's no way that was the chief." Havoc said voicing everyone's thoughts. They all turned to Alphonse as if expecting him to have the answer. Alphonse shook his head waving his hands in front his chest. "Don't look at me. He's been acting strange like that since he got back after storming out of the party yesterday. He even refered to Colonel as Mr. Mustang this morning. Until I pointed out. I swear it's like he's an entirely different person." Alphonse stated.

"Well maybe he is." Breda said with a joking smile on. Causing the others to either smirk, laugh, or give a disapproving look. "You know what... you might be onto something. This isn't the first time we have heard of something like this. With the new means of disguise these days any one could be like any one. It's all a matter of resources and acting." Mustang said causing the others to face him with shocked looks.

"You really think some one could do that to the chief?" Havoc ask. Mustang shrugged "Could happen to anyone. And no one had any contact with him during the many hours he was gone. It's not impossible for someone to take his place." Mustang explain.

An uncomfortable silence filled the room as the reality of the situation sunk in. "Okay! Okay! Let's not jump to conclusions! How about we just quiz him when he gets back? Will ask him stuff only Edward would know." Hawkeyes said trying to keep everyone from panicking. Hopeful nods went all around.

The door was suddenly kicked open and Edward with his more familiar scowl on his face was before it. "Mustang! You flaming bastard! You better be done with my damn report already! Because I'm leaving now and I don't give a fuck what you say! Come on Alphonse!" He said before rushing back out. Leaving everyone in shock.

"Now that seem more like the Edward we know and love." Fury stated looking on perplexed. "Oh something is definately wrong." Mustang said frowning. "From now on we keep a close eye on him. When he reports in tomorrow will interrogate him if it still doesn't seem right. Alphonse you have first watch. Will each follow him around today in shifts and see if we can learn anything
