Disclaimer: I don't own any of the character involved in SG: A… I only wish I did…

Author's Note: Hello all! This is my first attempt at fanfiction, so hopefully you all enjoy this. I wanted to write a story to explain why McKay is well… McKay. I really like his character and when I got the idea for this story, my mind went into overdrive. The story should be anywhere from 7 to 10 chapters, with updates ever week.

And PLEASE PLEASE PLEASE REVIEW! I thrive on comments and criticisms, so please tell me what you think!

"McKay! What did you do this time?" Sheppard yelled as he entered the science lab. Sheppard had been talking to Dr. Weir when the light in Atlantis flickered and a loud booming noise was heard coming from the labs. He knew that this could only mean one thing, Rodney McKay.

"Colonel," it was Zelenka who answered him. "I don't think that you're going to like this but, I must ask that you don't raise your voice at the moment. Things are a little complicat…"

Sheppard cut him off before he could finish. "I'll do whatever the hell I want to. Just tell me where McKay is, so he can tell me what the hell he did."

Zelenka sighed knowing that there was no point in arguing with the colonel when he was mad and pointed to the corner of the lab. John quickly moved to where the doctor had pointed. "Rodney, I swear if you broke anyth..."

"I'M SORRY," shouted a very small and very scared voice from the floor in front of Sheppard. John had expected when he came into the lab to see Rodney furiously trying to explain that whatever had happened was in no way his fault. Instead, Colonel Sheppard was stunned to find a little boy with brown hair and blue eyes in a shirt that was many sizes to big, huddled in the corner. "I'm sorry. I'm not sure what I did but I'm sorry! Please don't tell dad, I'll fix whatever I broke just please don't tell my dad." The pleading boy was almost in tears.

"McKay?" John voice had softened considerably. When the boy nodded slightly, Sheppard kneeled down to get a better look, the boy tried to backed up into the wall. It was then that he noticed that all the other scientist and lab assistants were on the other side of the room. He and Zelenka were the only people closed to the boy.

"This is what I tried to tell you, an artifact that we were studying suddenly activated. The next thing we knew McKay had been turned into this child. He remembers nothing of Atlantis and won't let anyone near him without... how do you say... freaking out."

"Great, just great," it was at this moment that John realized that it was going to be a long day. "Hey buddy, my name is John Sheppard. I'm gonna need you to come with me to see Dr. Beckett, okay?" John slowly reached out to grab the small boys hand when Rodney bolted. Sheppard quickly caught McKay and scooped the boy into his arms amazed at how light he was.

"LET ME GO!" Rodney shouted and kicked at the colonel. It was all he could do just to hold on to the boy. Sheppard told Zelenka to inform the doctor that he was heading down to the infirmary with the now child sized McKay and to find some way to fix this problem quick. The struggling stopped, and Rodney sat limply in the Colonel's arms. "Where's Jeanie? What's going on?" Rodney started to ramble softly.

The fight was gone from the small form in John's hands, he noticed that Rodney had gotten quiet as well. Looking down he saw that Dr. Rodney McKay, the astrophysicist, and self proclaimed genius had started to cry.

"Hey now, what's wrong? I'm sorry that I yelled at you, ok? We'll go see the doc, and find out what's wrong ok?" This only seemed to make the kid worse. Sheppard looked around the hall to see if anyone else was around, they were alone. Sheppard gave a sigh as he moved to lean against the wall. Every sudden gesture caused the bundle in his hands to cringe. Sliding down the wall in the sitting position with Rodney in his lap, he took a good hard look at the smaller version of his friend.

He looked about eight years old and Sheppard started to see that resemblance between the older Rodney and the one in his arms, however the boy was surprisingly light. Besides some similar facial features, nothing else about this boy was like the adult. Rodney had a presence about him that made everyone notice him, this child seemed like he wanted to disappear. Something was wrong. "Rodney, hey look at me McKay." The boy looked up slowly. "I know you're scared, okay. Before we go any further, we're gonna have a little chat, ok?" Rodney nodded sheepishly. "Alright, first off, do you know where you are or who I am?" He shook his head. John sighed inwardly, thinking about how this situation could get any worse. "Ok... alright then. I'm Colonel John Sheppard. I'm here to help ok. I need you to tell me what the last thing you remember?"

The boy tensed suddenly and looked down at the floor. John noticed and gently put a hand on his shoulder repeating the question slowly. "Jeanie broke a glass..."

"Okay, good, what else?"

"Dad heard it from upstairs, I told Jeanie to go outside and pretend that she was playing, I didn't want her to get in trouble." John nodded slowly, listening carefully. He kept his hand on Rodney's shoulder squeezing it gently trying to comfort the small boy. It seemed to help slightly, but the more Rodney told the more shaken up he seemed. "Dad came down and saw the mess. He was furious... he started screaming at me, but I said it was an accident. But he just got angrier." Tears started falling down Rodney's face and Sheppard's heart almost stopped as he realized where this was going. "He hit me and I fell onto the broken glass. My hand started bleeding... and that just made him madder. The last thing I remember was dad locking me in the closet again. I woke up and all these people were staring and asking me questions and... And Jeanie's gone... and..." The rest of the explanation was lost in small sobs.

He stared at the small Rodney and did the only thing he could think of. Sheppard wrapped his arms around the shaking form in his lap. Sheppard held the child as he cried, softly telling the boy that it was ok. He heard footsteps coming down the hall and looked up to see Carson. When John hadn't showed up in the infirmary the doctor had come looking for them.

John waved for the doctor to stop. He didn't want the startle the cry boy in his arms. Looked at the scene in front of him, and immediately understood. He would have to wait.
