Hello and welcome to my first attempt at a Criminal Minds fic. Reid is of course my favorite, and there just doesn't seem to be enough stories about him, so I thought I'd try one out and hopefully give a different romance for him than what you've probably read before. The story will be rated T for now, but could eventually become M because there are, of course, violent killers, and there's always the potential for language and sexual situations. Plot will be a mixture of original Criminal Minds content and my own. BUT, for now, here's the introduction to my Reid/OC fanfic. I'll try to update as soon as possible. Don't forget to favorite, follow, and review! Enjoy!

Desperado: in chess, a piece that is going to be captured anyway so it can "sacrifice" itself at the highest cost

"So wait, she knew your name?" Dr. Spencer Reid questioned.

"I don't know how I could forget a face like hers," Derek Morgan explained, baffled at his earlier run-in with an unknown beautiful woman who somehow recognized him.

"You've been with so many girls, you can't remember all their names," Reid noted.

Emily Prentiss smirked. "Come on, are you surprised?"

"This has never happened to me before," Morgan insisted.

"Hasn't happened to me before, either," Reid furrowed his eyebrows, stirring his piping hot, sugary coffee.

"It can't happen to you. You have an eidetic memory," Prentiss justified, as they rounded the doorway into the meeting room.

"Besides, you only got one name to remember," Morgan joked, prompting laughter between him and Prentiss and a sarcastic chuckle and eye-roll from Reid.

As the three sat down amongst their team at the BAU, they noticed an unfamiliar face standing at the front of the table with Hotch.

"Team, I'd like to introduce you to our newest member of the BAU. This is Hilary Green. She's a forensic accountant with specializations in digital forensics and information systems, and she will be working alongside Garcia to aid with the technical analysis of our cases. Green, these are SSAs Prentiss and Morgan, Jennifer Jareau, our communications liaison, Dr. Reid, and you've met Garcia and SSA Rossi," Hotch explained, pointing out each member of the team. I allowed my eyes to follow his introduction, getting a good look at each team member and nodding in recognition. "Ms. Green his highly qualified for this position, and I expect you all to welcome her into the team. Let's get started."

I sat down in the nearest chair at the round table. There would be time for more formal, friendly introductions later, but a new case had arrived, and the expertise of the BAU was urgently needed. A pregnant Jareau stood up to relay the details.

"Okay, uh, six victims have been killed in a series of burglar-homicides all over Central California. In order: Bakersfield, Fresno, Chico, and two nights ago, Allen and Brenda Haisley is Sacramento."

I shifted in my seat, tugging nervously at my blazer as the gruesome images on the screen displayed explicitly what had happened to the victims. At just twenty-six years old, I had job experience with forensic accounting, but worked primarily with corporate crime, not homicide. When I accepted the job, I knew the horrors that would go along with it, but I had a hard time grasping how someone could be motivated to do such evil things.

"Big area, we sure it's the same unsub?" Rossi chimed in.

"His DNA was found in all the homes," Jareau confirmed, nodding.

"They hadn't connected it because he crossed jurisdictional lines," Hotchner assisted.

"The head of the Sacramento field office has a multi-agency task force, and he wants us to run point."

"Looks like we've got a lot of investigators on this one," Morgan added.

"We'll streamline it if we need to."

"You should know that, uh, they've already named him the Highway-99 Killer."

"We'll deal with that when we get there," Hotchner nodded nonchalantly, reviewing the case file.

"He targets one-to-two-person households, he kills the victims while they sleep," Jareau sighed.

My attention was shifted in the direction of Dr. Reid, speaking up for the first time. "Blunt force trauma with objects found at the home, multiple bashes to the head." He set down the file, a quizzical expression outlining his prominent facial features. Despite the morbid context of the situation, I couldn't help but notice that the young doctor was quite handsome. I'd already noted that Morgan was incredibly attractive, but there was something about Reid's disheveled, long hair and traditional-styled clothing that made him look as though he was pulled straight from a high-end fashion magazine.

"After he kills the victims, he ransacks the home for valuables."

"What's unique about this unsub is that after he kills them, apparently he sits down to dinner in their homes," Hotchner continued. The images on the screen continued to increase with gore. Hilary silently sighed in relief that her job was to connect numbers and patterns, not to deal with the human tragedy itself. "They found his DNA all in the food on the table." As the profilers continued to theorize about the unsub, I sat observantly, carefully watching each and every member of the team. Patterns were, in fact, my specialty. I noticed them in numbers and, in this case, people.

My mind zoned back into focus at the sound of Hotchner's authoritative command. "Garcia, take Green to your office to familiarize her with the technology. Everyone else, wheels up in thirty." It was obvious that the true team introduction would indeed have to wait.

Penelope Garcia, whom I'd briefly met a few days ago, headed my way, taking hold of my arm without a moment's hesitation. "You have no idea how excited I am to have you working with me. They never let me tag along," she poked out her bottom lip in a sarcastic pout. The members of the BAU began to file out of the room, Garcia and I following in a different direction. "Come on, my little golden ray of sunshine. I will show you the real brains behind this operation."

"Welcome to Mama's lair," Garcia announced as she thrust open a door to reveal a dark room, consisting of a single rolling chair, a computer system, and over a dozen monitors. It was obvious that Garcia had made the space her own. Like her unique fashion sense, the room was decorated with various trinkets, splashes of bright pink and yellow, glitter, and pictures of baby animals spaced throughout. "Hm," she thought, glancing at the one and only chair in the room. "You sit here, and I'll be right back." I took this brief time to further examine the room. The computer system was intricate, far more advanced than what I was used to working with. A photo encased in a bedazzled purple frame was placed next to the mouse. It displayed the entire team I'd met earlier, dressed in unprofessional clothing and laughing, contrasting the serious expressions I'd initially been introduced to. This photo revealed something that was undetectable in the conference room. They were like a family. I didn't know how the members of the BAU would welcome my entrance into their workforce, but seeing the close bond made me realize how much I missed my own family, the family I left six hundred miles away to take this job.

"Here we are." Garcia rolled in a chair, and plopped into it, scooting closer to the computer keyboard, her elaborate jewelry jingling with her every movement. "So, Ms. Green, tell me about yourself."

"Well I..," I began, unsure of where to start.

"Of course, I already know all about you," she winked. "I did do a little research, couldn't help myself." Garcia motioned to the many monitors. She'd looked me up, no doubt. I smirked. She was definitely a character, but her intentions were seemingly sincere, and we'd be spending a lot of time together, so she was my best bet for a new friend in Quantico.

"Well," I giggled. "I'm not sure where to begin, so what don't you know?" I quizzed sarcastically.

"Oh baby, I know everything, but I like the conversation."

"Okay," I began, tucking a strand of honey-colored hair behind my ear and adjusting my black framed glasses. "I'm from Atlanta. I graduated Emory and got my CPA, interned and worked a while there at a firm investigating corporate crime, and then got the job here. I have an older sister and a three year-old nephew, whom I miss very, very much already." I paused. "That's about it, I guess," shrugging my shoulders. "Oh, and please just call me Hilary or Hil. I hate formalities," I added, making it clear that I definitely did not want to be addressed as 'Ms.'
"So what about you?"

"Trust me, you'll find out plenty in no time with how much we'll be in here together in here." She shook the mouse, adjusted her bright pink glasses, and quickly typed in a code to unlock the computer. "But I can fill you in on the team." I nodded with interest. "Okay, so you know Hotch. No, he doesn't ever smile at work, but never fear, he isn't as scary as he appears. You also know Rossi, super cool guy. If you want to get on his good side, just ask about his carbonara; it's a win win for both of you because it is de-licious. Then there's Jennifer Jareau, call her JJ, and Emily Prentiss, the BAU's beautiful badasses. Oh!" she exclaimed. "We should all have a girls' night soon when everyone gets back. We all usually go out together, but then men can do their own thing for once," Garcia laughed, clapping at her idea.

I smiled. Garcia was attempting to accept me into the team, so I was hopeful about the others. "If there's wine, I'll be there."

"Oh honey, it wouldn't be a girls' night without it. There will be plenty. Where was I, oh. Morgan is my delectable chocolate chunk," she insinuated with a grin and wriggle of her eyebrows. "And finally our own little genius boy wonder, Dr. Spencer Reid," she finished with a nudge and.

"Why are you looking at me like that?" I giggled, noticing her sudden intense observation of my appearance.

"Because, my fair golden beauty, you are now the BAU's other young smarty-pants."

I rolled my eyes and exhaled a chuckle. "I'm definitely not a genius, Garcia."

"You finished top of your class with joint degrees and a minor at one of the most competitive schools in the country, dear. You might not have an IQ of 187, but you could keep up with him better than any of the rest of us can. And who knows, maybe you could even get him to shut up for once, if you know what I mean," she joked suggestively.

"Garcia, I have been here for less than two hours, and you're already trying to set me up," I laughed. This wasn't the first time someone had found a 'perfect match' for me. Dating was not my specialty, but everyone I knew sure tried to force it on me.

"Fine, fine," she raised her hands innocently in surrender. "No match-making..for now." She winked again. "Here, I'll show you how to use everything, and then we can start digging. The sooner we catch this guy, the closer we are to popping corks."

So that's the first chapter! Future chapters will get longer from now on, but I just wanted to get the introduction out. This story begins in season 4. Please review and let me know what you think!
