A/N: Okay, so I decided to write a Beckett/OC story, because I freaking love him! His accent just makes me giggle every time, I've always wanted to write one. I started to watch SG:A from the beginning, so I decided it was a good place to start. Hope you enjoy, even though...*refrains from spoiler alert*

Disclaimer: I own no one but Selena Fuentes. Everyone else goes to their rightful owners

Summary: He's a doctor from Scotland. She's a general's daughter and a captain in the Army. Yet, by chance, they happen to be on the same expedition. What happens when a man of medical science and a woman of mechanical knowledge and military training come together to work for the same cause?

Move along, move along like I know you do

And even when your hope is gone

Move along, move along just to make it through

All-American Rejects — Move Along

Selena stood outside the Stargate, ready for Sumner's command. Her M-16 was poised, ready for danger.

"Okay, everything's clear," she heard Dr. Weir say. Selena stepped backwards to collect her duffel bag. She had been allowed very few personal things, but Atlantis was to become her new home. The job that she shared with her father, was one she was hopelessly devoted to. She was currently been groomed for a promotion from Captain to Major in the US Army. O-3 was her rank, and she was determined to make her father proud.

When she spoke her surname along with her rank, soldiers knew her father. He was a general, pressure was Selena's daily routine. Her dark hair sat at the nape of her neck, tied back in a tight bun. It felt like the ground was jerked from her as she stepped through the Stargate, keeping her weapon at easy access. It was like sliding on the big, shiny slide at the playground where she used to live as she crossed into an old building. The Atlantis Expedition was one of the most top-secret operations, a massive honor to even be recommended for, let alone selected.

Selena took in the building with wide brown eyes as she carried her things. There were a few soldiers she knew, but most of them, she didn't.

"Major John Sheppard," a man said, extending a hand. She shook his hand, liking his easygoing demeanor. His dark hair was unkempt and hazel eyes shone back at her, alight with boyish wonder. It was clear that he was as in awe of the expedition as she. "US Air Force."

"Captain Selena Fuentes," she replied. She had been born and raised the majority of her life in Puerto Rico and had often been reminded of her 'exotic' accent. Selena was Hispanic; there was no hiding that. "US Army." Wait for it...

"Nice to meet you," Sheppard said as he slid his bags onto his broad shoulder. He seemed easy enough to get along with and Selena could see no problems between them in the near future. He hadn't even picked on her branch of the military.

"You as well," she replied. Strands of her thick, wavy hair wound its way into her face, partially shrouding her coffee-colored eyes. She used a hand to brush the locks out of her face and tuck them behind her ear.

"You pack light," Sheppard commented. "Usually, the women I know are usually bogged down by luggage." He nodded to her small duffel bag. Inside, were her favorite few personal items. The entire series of 'Happy Days' and 'Joanie Loves Chachi' remained packed inside the black canvas bag, along with her few civilian clothes.

"Clearly, I'm not like other women," Selena replied with amusement. After finding Dr. Weir, she was sworn in and told to go to Control Room for a briefing.

Carson squinted at the piece of paper he held in one hand and raked his free hand through his dark hair.

"I don't even know where I'm supposed to be," he muttered as he made his way down the hall. Something solid hit his torso and he mustered a grunt. Looking around wildly, his gaze finally settled on a petite Hispanic woman, dressed in a military uniform. "Sorry, lass."

Her messy dark hair curled under her ears as she tilted her head to meet his eyes. She was attractive, he noticed. Honey-tinted skin, big dark brown eyes framed with long lashes.

"Sorry, I wasn't looking where I was going," she apologized. Her accent was unique, as if she were from a foreign country. He held her arm and helped her to her feet.

"Do you know where the Control Room is?" he asked. The woman twisted her mouth in thought and shrugged.

"I was on my way there myself, honestly," she responded. Her chocolate-brown eyes were apologetic as she smiled, showcasing slightly crooked teeth. "We could probably find someone who could give us a hand."

"I'm Dr. Carson Beckett," Carson said, extending a hand. The woman shook it, her smile widening.

"Captain Selena Fuentes," she introduced herself. "Please don't ask if I'm related to General Fuentes."

He must have looked confused, because she laughed. "Sorry, it's a common question when I introduce myself," she apologized.

"No worries," he shrugged it off. "Let's try looking lost and we'll see if we can find the Control Room."

"Yes, Daddy, I've been playing nice with the other kids," Selena said on the broadcaster. Her father's dark eyes were warm with amusement and he chuckled.

"That's very nice, Lena," he teased. Luis Fuentes was a tough-looking man, with a "don't-mess-with-me" attitude. One look sent most people skittering away in the other direction. But he was a man who was ferociously loyal to his country, his family, and his men. "Have you made friends?"

Selena smiled. "There are some very nice people," she answered. She had known Lieutenant Ford prior to the program through her younger brother who served in the Marines with him. Luckily, the two were on the same team headed by Colonel Sumner. "Easy to get along with."

"That's good," he said slowly. Even though she was a grown woman serving in the same Army he was, she knew her father still worried about her. Selena was his youngest daughter out of eight children. Because her father was on the IOA, he knew well what she was doing. As far as the rest of the family was concerned, she was stationed at Ft. Bragg, North Carolina and training privates to fix machines. Very few things came to her as easily as fixing and tinkering with machines did.

"I hope to hear more from you than just reading your reports," he told her. Selena sighed and tightened her ponytail, something she did when things were awkward. She often fidgeted.

"It's not like I can talk to you every day, Daddy," she reminded him. "I have a job here that needs to be done. My job is figuring out Ancient technology and repairing the wiring. It's pretty old, you know."

"And no one can figure it out like you can, Tinkerbell," he said fondly. 'Tinkerbell' came from her fondness (or obsession) with Peter Pan as a child and her fascination with mechanics and engineering. The sound of a knock on the door alerted her that her time was up.

"Thanks," she told him. "My time is up, so I gotta go. Give Mama and the others my love and tell them that I'll be in touch as often as I can."

"Okay," he replied. She signed off and stood up from the chair. It was time to move along and do the job that was required of her.
