A/N: Okay this is going to be a Twilight/Vampire Diaries/NCIS crossover, bear with me please until I establish the storyline adequately and how these get intertwined, and I will give a backstory for most of the things but in short:

From Twilight we are about five years after New Moon, Edward left Bella, but they didn't get back together, she didn't jump off the cliff and Alice never came back, she moved from Forks to Mystic Falls, where she was turned into a vampire (not a Cold one, a regular vampire).After having her thirst under control she settles in Washington D.C., joining the police there because she felt that she could use her supernatural strength for the better, from which NCIS recruits her.

As for Vampire Diaries, it's a bit hazy, going to go AU real fast, many diversions from the series with other parts intact, but a good reference point would be maybe the end of season 6 (possibly 7 though I haven't gotten to it yet :O ), Elena is back to human from being a vampire, in deep-slumber, although when Bella was in Mystic Falls first she wasn't one yet (season 3), so Bella missed that whole chunk with her.

For NCIS, after Ziva leaves (so after season 11), but instead of Ellie Bishop, we get Bella, not that much of a focus, more like a plot device.

At the outskirts of Washington, D.C., in a nearly abandoned warehouse district, a woman was dragged by two men. She was a brunette, but her hair was not just any plain brown color. It was rich and intense, kind of like mahogany with a hint of red when the rays of the sun danced on it, providing lovely contrast and frame to her pale skin, matching her chocolate brown eyes. Her face was heart-shaped but angular and well defined. All in all, she was stunning, even more so with her slender body hugged by a slightly too tight red dress, accentuating her small curves, especially her tiny waist and perky breasts.

Some might have considered this a burden, given that her striking looks were the very thing that led to her abduction. But as a matter of fact, that was precisely what she had been counting on.

This should be an interesting day, the woman thought to herself as the two burly thugs "escorted" her from the back of their nondescript white van towards the greyish building across the lot.

The brunette was working on a case. One very important to her heart. That is how it happened that she purposefully allowed herself to be "kidnapped" – as the assailants thought – before the clock even struck 10 AM. Some jobs were just worth the inconvenience.

Not to mention this move saved her the trouble of tracking them down one by one. There wasn't really much they could do to hurt her anyway. Not unless they knew what she was, but given that they had tried to use chloroform to knock her out, it was pretty certain they had absolutely no idea. She gladly played along with their scheme just to make sure her cover stayed intact, both her professional and personal one. But this would only be a concern until she was done with them.

To tell you the truth, this development would speed up the investigation the brunette was conducting at the moment more than she had dared to hope. Given the right circumstances, she planned to make them sing like canaries. Circumstances like finally losing that damned blindfold they had put on her after snatching her off the street just to make sure she didn't know where they were going. Little did they know, she had other means of finding out. There wasn't really much you could hide from a vampire. Given that they had crossed two train tracks – a mile and a half apart from each other from the origin of her "pick up" – turned left once then right three minutes later and that she could hear the bustling noise of the highway on their right side approximately two miles away, the undercover agent knew precisely which dingy little warehouse district they were in. Even the fact that she was probably being taken towards the second to last warehouse on the left.

The brunette could have easily broken away the ropes they had used to tie her to the chair she was sitting on, but she was still waiting for their boss to arrive, whom she was really after. This petty little gang of criminals dealt in human trafficking, to be more precise in the trafficking of children and teenagers, and to be honest, there weren't many things that made the vampire angrier than the mistreatment, abuse, and exploitation of children. After the child of a Navy Officer had been abducted, she quickly jumped on the case, finding the little girl in less than three hours. It could have taken less with her vampire senses and all, but she didn't want anyone at NCIS to get suspicious. Also, this wasn't just a personal preference, she didn't need all the federal agencies poking around in the world of supernatural. It was for the better for them to remain clueless.

All that was left was ending this little operation once and for all. But this was more like a personal hobby of hers, she wasn't here on official NCIS business. The direct culprit that was responsible for the abduction of the Navy Officer's daughter was already behind bars. Unfortunately, he didn't snitch on his boss in the official interrogation, but a little visit from our vampire unbeknownst to anyone did the trick.

Finally, the ringleader decided to show up, the brunette could hear him talking on his phone just outside the far entrance of the warehouse about preparations for kidnapping some other poor kid. She wasn't about to let that happen.

Without his henchman noticing, she shifted in her chair, getting ready to pounce when the moment was right. The boss walked in, ordering his men to kill her. He wanted revenge for messing up his business last time. So much for her cover not being blown… Her original plan was to be taken under the guise of being sold off as well, but it seemed she had been recognized.

Oh, well… This was her cue to act. Within seconds she had everyone bound by rope or in handcuffs. It's not like she had to worry about them telling anyone about her capabilities, she would just compel them to forget later.

"Where are the other kids?" the brunette asked in a calm manner, leaning over the fat-ass gangster. It was so cliché, it almost hurt. The vampire wasn't concerned with such things at the moment though.

"What the… how?" the boss wondered out loud, confusion and utter fear sitting on his features.

"That is not important right now. Where are the kids?" she repeated, her patience wearing thin. Usually, to keep in practice with her agent cover and interrogation skills, she liked to start off the conventional way. It was a bit tricky with not having a good cop to counterbalance her frightening demeanor.

"Like hell we are going to tell you anything, you monster!" he spat in her face, trying to struggle out of the ropes that now had him tied down. Talk about turning the tables.

"That's not really nice is it?" the vampire leaned in closer, her pupils dilating. "You are going to tell me everything about your operation, in detail and honestly. Where are the kids?"

"Two already on a ship to Malaysia, two locked up in a warehouse at Adams Place, and a girl is about to be kidnapped from the Lincoln Street area, two of my men are already on their way," the ringleader mumbled out in an obedient daze. In the background, his henchmen started to get even more nervous.

"Just great!" the agent sighed in frustration and flipped her untraceable phone (that even NCIS didn't know about) out to call MPD. "Hi, I would like to report a crime! A child is being kidnapped on Lincoln Street, please hurry!" she said in a perfectly acted out panicked voice then hung up immediately. "Where are they taking her if they succeed?" she continued her interrogation as if that tiny intermezzo had never happened.

"Here," the boss admitted without hesitation.

Good, she thought, she would just wait for her in the warehouse in case the police didn't get there in time to prevent the kidnapping. "What about the kids on the way to Malaysia, which ship are they on? Where is it going exactly? When is it scheduled to arrive?"

"EVER DECENT 0686-099W, Bintulu, September 20th," the fat man listed the details. The vampire didn't need to write them down. She had almost perfect memory.

Sometimes the brunette wondered how much easier the whole justice system would have been if there had been more vampires willing to work there and submit themselves to the ordinary limitations that humans had to face. Tricky business must admit. With the whole blood drinking thing going on. But her kind theoretically could pull it off. Their bite wasn't venomous. Turning someone required for the human to ingest vampire blood shortly before their death. And they could resist overfeeding and thus killing their prey. A little compulsion afterward and it was as if they were never there. And of course, there are other means. Blood bags, hunting animals instead. Endless opportunities. Only if more vampires were willing to take this route, but alas… most liked to give in to their "true" nature. Some would argue that point. The brunette had known a doctor who was a vampire and had never tasted human blood.

"Any more associates of yours who are not currently here, or en route to kidnap that girl?" the woman asked her last question. They were just about done here.

"No," the criminal shook his head.

"Good. Now…" she looked deeply into his eyes again. "You will forget everything that happened here today, you never saw me, never kidnapped me, you will go and give yourself up at the police station and admit to every crime you have ever committed," the brunette went and did the same with all of his associates as well.

She waited two hours just to make sure that the other culprits were captured and didn't return to their hideout. In the meantime, she contacted her friend at CGIS on her regular work phone about a tip she got regarding the kidnappings and a certain cargo ship. Then let the human traffickers loose, who under the influence of the compulsion got into their van and drove straight to the local precinct.

Bella Swan's face broke out into a proud smile as she watched them disappear from sight. Her father's blood was strong in her it seemed, even after everything. These moments were what she lived for. Whether done officially or not.

Looking down at herself, the now ripped red dress and stockings, broken heels, she sighed. She had to change anyway. At a superhuman speed no one could possibly see her, she whipped to the other part of town to her apartment and picked out a more work appropriate attire. Jeans, a loose blouse, leather jacket, and boots ought to do it. Then drove her Chevy Pickup to work, even if running would have been faster. Some pretenses you just had to keep up.

"Where have you been, Probie?" Tony asked with a teasing smirk as Bella got off the elevator and entered the bullpen with a coffee in hand. Her morning endeavor took a little longer than she had initially anticipated and she had only taken time off until noon. Always a good idea to bring coffee if you aren't sure whether you are in trouble with your boss or not. Assuming of course that your boss is Special Agent Leroy Jethro Gibbs.

"Personal business to take care of…" Bella retorted with a stern look that told him to back off as she placed the caffeine offering on Gibbs's desk. "By the way, I got a tip from an informant on the kidnapped children cases. Apparently, two kids were shipped to Malaysia."

"Yeah, I heard the whole gang gave themselves up at MPD," even confessing stuff like stealing from the candy store when they were ten, which was kind of weird, but he left that piece out. "Also two of the four missing kids were found safe and sound," DiNozzo probed further. Truth be told, some cases miraculously moved along when Swan took some "personal" time off. Coincidence? Think not!

"Yes, I heard that too. I'm glad. I already contacted the coast guards about my tip, I hope they can intercept the ship and find the remaining two soon enough," the brunette, oblivious to Tony's suspicions, sat down at her desk, throwing her bag down by her feet and fired up the computer.

"Hope so too," McGee chimed into their conversation too from the other corner.

"Apparently there was even a thwarted abduction on Lincoln Street. Also an anonymous tip, my buddy said," the former Baltimore police officer, the now agent, added nonchalantly, leaning back in his chair with his hands at the nape of his neck. He had his contacts at Metro Police, which came handy in all sorts of situations.

Something in his tone caught Bella's attention now. He seemed calm, just curious, his heartbeat not indicating anything more than that. At least nothing that would suggest that he was onto her real identity. He wouldn't take that news this serenely, she believed. This whole assessment hadn't taken her more than a hundredth of a second, and she answered with her usual, almost indifferent voice.

"Maybe there is hope for humanity, after all. Decent citizens not having gone extinct yet," the brunette looked into her fellow agent's eyes with a small, but thoroughly genuine looking, smile as she said that. Lying was second nature to her. She could control every facet of her facial expression and body language. If needed even her heart rate. How else would she have passed the many routine lie detector tests over the years?

Given Tony's reaction, it worked, he looked utterly thrown off his game. Just in time too for the elevator to bing again. Even though her desk faced in the opposite direction, she knew exactly who had come onto the floor without even looking. And Bella would have bet everything she owned that they had a new case, so she got up from her chair, swinging her backpack over her shoulder.

"Oh, hi, Boss!" Tony straightened up quickly as Gibbs walked in.

"Gear up. Dead petty officer in a small town called Mystic Falls," the team leader whipped past Bella's desk to his own to grab the cup waiting for him.

As she heard the end of that sentence, the female agent, who was already in the aisle between her own and Tony's desk on her way to the elevator, spun around her heel almost too fast for human speed. Never in a million years did she think that she would have to go back to that place ever again…

Bella had never been much of a talker, but she was always up for some good-humored jabbing between colleagues to ease the stress of what their job entailed. Dead bodies weren't fun. But not this time. Memories and thoughts associated with their destination flooded her mind.

The place of her transformation, Mystic Falls. The brunette had vowed to leave it all behind, forget it altogether, supernatural and whatnot when she had fled nearly five years ago. Although she hadn't spent much time there, only a mere few weeks, it had changed her forever. Literally and figuratively speaking.

Much the same as Bella did with Forks. After Edward abandoned her in the woods, to never return, there wasn't really anything left in her birthplace for her. Graduation was pretty much her cue to jump ship and travel the country, trying to find herself. Six months in, she had visited this small town in Virginia, which had promised a much calmer, more normal life than Forks. Everyone was so lovely, she fit right in, making friends instantly. Bella could have imagined living there for a while. Little had she known at the time that she had stumbled upon another supernatural hot-spot. It was as if she was a magnet for it; a magnet for danger for sure.

Bella was so caught up in her thoughts that she didn't even pick up on the little tell-tale signs that would have told her that her two fellow agents were itching to get her to talk. One of them should have ridden with Gibbs per protocol, but both wanted to find out about her peculiar reaction from earlier, and McGee just hopped in the backseat without complaint when she decided to ride shotgun by DiNozzo.

"You're awfully quiet," Tony remarked with a little concern in his voice, paying her a quick glance. Agent Swan decided to ignore it and continued to stare out the window instead, pretending to be lost in thought. "Are you still hung up on the missing kids?"

"Yeah," she lied effortlessly. Everyone knew how passionate she was about that case. What a great excuse! Too bad that she wasn't really on her ace game in covering her emotions at the moment. No doubt Tony hadn't been fooled either.

"Don't worry, CGIS is on it already, they will be home with their loved ones in no time," the ever-optimistic and care-free agent tried to lighten the mood.

"Is Borin on the case?" Bella asked suddenly turning to Tony, actually curious. She hadn't really followed up on it after getting the word to the partner agency, what with everything that had happened shortly after. How differently this day had started out…

"Yepp," DiNozzo replied quickly, stressing the p.

At least someone was keeping proper tabs, Bella thought.

"Then I have no doubt, it will get done quickly," she considered the conversation ended with that and continued to stare at the trees flashing by them. So much greenery. Although not quite as sickly moss covered like Forks. Another place she wished to never have to think about again.

Tony gave a meaningful look to McGee on the backseat through the rearview mirror, which Bella caught but paid no mind to.

"So I heard you lived in Mystic Falls for a while..." McGee probed carefully, trying to start the conversation back up.

"Heard or more like looked in my file?" the female agent snapped at him, calling his bluff quickly.

"Sorry…" he said guiltily. "I didn't mean to pry, but after your reaction in the bullpen, I had to check. You know… to make sure you have no personal involvement in the case."

"Rule 6, McGee," Bella sighed before continuing. Why apologize for something you'd do again in a heartbeat? "Only for a few weeks, and it was a long time ago. Don't want to talk about it," she said in a clipped tone. The number of reasons could comprise a mile long list. She regretted whole-heartedly registering herself as a permanent resident of this town all those years ago. But she couldn't change the fact, and tampering with federal records was quite risky.

"Okay..." Tim trailed off warily.

"We are almost there," Tony decided to interrupt the awkward exchange. Well, that didn't go exactly as planned. Just what could have possibly happened here to their ever stoic Bella to have her so riled up?
