This is my FIRST foray into this particular fandom. Please be brutally honest. I need all the help I can get.

Since this film is almost like an alternate universe, I'm going to use bits and pieces from all over the Universe to construct MY world.

If you notice certain parallels with another show, it's somewhat intentional. I've done some research and realized that there is scant little on law in the Star Trek universe. I'm going to use all the knowledge I have from JAG as it's the only real legally-focused show I've seen ever. Plus, I really love Mac. My OC is going to share a similar backstory but with my own twists. Enjoy!

Mentions of Spock/Uhura

This was what she had wanted, wasn't it?

Staring up at the vast, hulking mass of the USS Enterprise, Colonel Gabriela Rodriguez couldn't help but wonder whether this was really what she wanted. The smooth curving lines of the ship all but gleamed in the sunlight of the Arizona heat, the rounded edges taking nothing away from the imposing structure.

This was the assignment everyone dreamed of. A year spent onboard the Enterprise meant getting more than a few rungs up on the ladder. Fast-tracked promotions, clout, respect – these were the reasons for the envious glances she had gotten in the corridors of the Judge Advocate General's Office. When Admiral Deragon Lucifel had called her into his office, the last thing Gabriela had been expecting as to be placed onboard the Enterprise indefinitely. Apparently, Captain James T. Kirk had made a name for himself.

An infamous one judging by the smirk on the Admiral's face.

Gabriela had shared a close relationship with the Admiral. Maybe it was because she had never really had a father figure in her life, but the Admiral's dedication to his work and his staff had made it easy to develop what some would call a steadfast affection for the man. Being his Chief of Staff had all but cemented the bond between the two of them, as had their shared time in the Starfleet Marine Corps. Lucifel had been a founding member and Gabriela had spent the greater part of her formative years in the Academy and the Corp. While she knew that many balked at the idea of the strict rigidity and disciple required of the service, Gabriela had embraced it with open arms. After spending years drifting and lost, the Corp had become a haven.

'Ma'am?' A soft voice called from behind her. Blinking, Gabriela turned her head to see Ensign Andrea Wrenn standing in the threshold of her office.

'Ensign Wrenn, what have I said about calling me Ma'am?' Gabriela said, shaking her head and offering the other woman a smile.

'The Admiral requests your presence in his office Ma'am,' the Ensign responded, either choosing to ignore Gabriela's remark or just plain choosing not to hear it. Gabriela couldn't help but chew her lip in response.

Oh God. They're here already? What time is it? Calm down Marine. You can do this. Deep breaths.

'Are you alright Colonel?' Wrenn asked, giving Gabriela a concerned look.

'I'm fine. Just a bit…I'm fine,' Gabriela said, straightening her blouse. She resisted the urge to check to see if the back of her skirt was too wrinkled.

'Your skirt is fine Ma'am,' Wrenn assured her knowingly. Gabriela's nervousness was something she usually kept well in check except to those within her so-called "circle of trust". Wrenn, who was practically glued to Gabriela's hip as her assistant, considered herself lucky to be on of those few.

'Do you think I'm doing the right thing Andy?' Gabriela asked. Wrenn appeared to straighten at her question. Closing the door with a quick turn of her wrist, and making sure the blinds were shut tight, Wrenn placed her hands firmly upon her hips.

'You have spent the past two years telling me that you needed time away from Arizona, away from the base at Texas. If there's anyone who deserves this Gabby, it's you. The amount of cases you win, the way you make sure the Office doesn't collapse around its head because of another of Commander Cahill's stunts,' Wrenn said, sharing a knowing smile with Gabriela as they both thought of her best friend. Commander Timothy Cahill was a former pilot who had decided to retire his wings in favour of a desk and chair. Unfortunately, that had done nothing to tame his hot-wired temper and innately reckless nature. Not to mention the string of women he had left broken-hearted outside the steps of JAG.

'Thanks Andy,' Gabriela replied gratefully, though she could still feel that heavy weight pressing down onto her shoulders. 'Tell the Admiral I'll be there in a minute.'

Face set in approval, Wrenn left. Gabriela sighed, running a finger along the polished wood of her desk.

Time to do this Marine. You survived the Dominion War. This is nothing compared to everything else you've been through.

Tracing the scar that ran along her forearm under her uniform, Gabriela squared her shoulders and made her way towards the Admiral's office. Waiting patiently as Lucifel's yeoman announced her presence; Gabriela furtively ran a hand through her hair and attempted to smooth out her blouse before the Admiral's booming voice signaled for her to enter.

Two figures stood facing the Admiral. Both were tall and leanly muscled, though one had fair hair and the other dark. Noticing the pointed ears on the dark-haired one, Gabriela searched her mind for the name of the Vulcan that was supposed to be Kirk's first officer. The Romulan destruction of Vulcan had hijacked Earth's entire media system for weeks. Seeing that world swallowed whole, it had made her pause, wondering whether if she had disappeared if there would be anyone who would miss her.

Now isn't the time.

'Sir,' Gabriela said, snapping to attention. The two figures turned to face her as the tic that pulsed above the Admiral's left eyebrow thrummed incessantly. It only did that whenever he was either extremely annoyed or angry.

Uh oh.

'At ease Colonel,' the Admiral seemed to bite out before trying to relax.

'You're a Colonel?' The blonde man remarked with skepticism. Gabriela could immediately feel her hackles rise. As a woman in a predominantly male field, his question was commonplace. It didn't mean that it didn't rankle any less.

'With that wit, I assume that you're Captain James Tiberius Kirk,' Gabriela replied bitingly.

The Admiral gave an aggravated sigh. Kirk's first officer appeared to study her, his face stoic.

'She doesn't appear to like you,' Spock mentioned, much to Gabriela's mortification. Instead of looking affronted, Kirk only laughed.

'Hey, you weren't exactly a paragon of friendliness when we first met Spock,' Kirk said, clapping Spock on the shoulder. The Vulcan raised an eyebrow at the contact. 'But I've grown on you.'

'Like a parasite,' Spock mumbled. Kirk laughed even more.

'Colonel Gabriela Rodriguez, this is Captain Kirk and First Officer Spock of the USS Enterprise,' Lucifel finally cut in. 'Gentlemen, this is your new JAG.'

'Sir,' Gabriela forced herself to maintain a civil tongue in the face of Kirk's asinine grin. Spock returned her greeting with a sharp jerk of his head.

'I still don't understand why we need a JAG,' Kirk said, eyeing Gabriela as if she were a piece of meat. His eyes seemed to travel over her from head to toe, and then back again. Gabriela glared.

'After the Romulan invasion, and Captain Pike's advice, the Federation deemed it…prudent,' the Admiral seemed to pause, as if savouring the word, 'that you have a legal expert on board to remind you that there are indeed rules and regulations to be complied with aboard your ship.'

'I didn't hear any complaints when my rule-breaking kicked the Romulan's ass,' Kirk shot back.

'I believe that Colonel Rodriguez will prove a valuable addition to our crew,' Spock cut in gracefully. While it wasn't quite the resounding acceptance Gabriela had been expecting, it was still better than nothing.

'Colonel Rodriguez is one of my best Captain,' the Admiral ground out. 'I expect that she will be treated as such on board your ship.'

'Of course,' Kirk replied with a full wattage smile. His blue eyes crinkled at the corners and his teeth flashed. 'I'll make sure that the Colonel is made to feel very welcome.'

Not missing the innuendo in his voice, Gabriela injected as much venom as she could professionally allow within close proximity to her commanding officer and new Captain.

'I look forward to it Sir.'

Spock's face remained impassive, the Admiral relaxed marginally while Kirk returned the challenging stare directed his way.

'Welcome to the Enterprise Colonel.'

Watching Kirk and Spock shake the Admiral's hands, effectively sealing her new post, Gabriela thought that maybe, just maybe, this was what she wanted.

So why does it still feel like I'm running away?
