A.N: OK! so this is my second fic and for those who have read my other one there is going to be alot of unexpected twists along the way... the way I like it :P I would like to thank my friend Allison (ForeignMusicLyrics) for helping me plan this fic and also according to her I chose the title "Foreign" after her name haha... 143 Alli!

Anyway I really do hope you like it , first chapters are always a bit slow because you have to set up the story and explain things so please give it a go! :)

Disclamer: I do not own NCIS or the characters, made up the character Ryan for the purpose of this fic.

Tony walks out of the elevator onto his floor spinning on his heel as he walked backwards, then spinning around again to see the amused face of Ziva as he listened to his IPod. He hasn't used his IPod Abby had given him for a while now but had found it last night when going through some draws and has been listening to it all morning. He gave one of his cheesy, yet weirdly charming smiles to Ziva as she tried to hold back laughter by how amazingly bizarre he looked dancing in the office and by the number of faces that had drawn attention to him. He walked behind his desk dropping his backpack on the ground and taking his gun, keys, badge and wallet out dumping them on the desk, sliding open the top draw and in one swift motion pushing the whole lot inside before slamming it shut and falling back into his chair making it spin around.

"Somebody is in a good mood." She said walking across the bull pen and standing in front of his desk with a curious smile.

"What?"

"I said somebody is in a good mood!"

"What? Can't hear you!" He could see she was getting frustrated which only made him want to stir her up more.

"Well maybe if you take out your headphones!"

"What? Still can't hear you!" She reached across his desk and yanked the earpieces out looking quite agitated and he looked up with a 'Wudda do that for?' look on his face. "I said you are in a good mood this morning, yes?"

"I know I heard you the first time." He smirked as she rolled her eyes and walked back to sit behind her desk forcing herself not to go over and wipe the stupid smirk off his face. "It's the music, found the IPod Abs gave me last night, I now understand why people think music is therapeutic. It has really put me in a good mood; maybe you should try it, it seems you need to lighten up a little." He again had the stupid smirk on his face as he was enjoying teasing her; it was so fun because she reacted so easily. She sat across the desk and mouthed what he said mocking him before turning her attention back to the computer screen.

"I don't know how you two even function." McGee put in at the end and Tony had not even noticed that he had been sitting there the whole time; he normally didn't notice anyone in the room when Ziva was around. Not that he would ever admit it.

"Well morning there McGoo, didn't even notice you were there. So how are you this morning, do you also need some music therapy to lighten your mood like Miss grumpy pants over here?" He felt a pen hit him in the side of the head as he yelped rubbing the spot of impact.

"Now I am in a good mood." She was now the one to have a playful smile across her face as Tony frowned back at her.

"Uncalled for"

"Maybe DiNozzo, but you sure deserved it." Gibbs paced across the bull pen to his desk, bringing the aroma of coffee through the office, as Ziva's smile grew obviously agreeing with Gibbs.

"Morning Boss, got a case?"

"Nope, just a lot of paperwork DiNozzo, so get to it." Tony frowned as he saw the stack in front of him, hopefully they would get a case soon or it would be a long day ahead.

Special Agent Fornell stood in the elevator of the NCIS building with a younger agent also from the FBI. He didn't really like him that much but he had been temporarily assigned to his team by the director and he couldn't argue. The man was very cocky and seemed to think of himself a superior to everyone around him, he obviously believed that he should not have to take orders from him as he continued to question his motives.

"So why are we here again?" Fornell sighed as he forced a response.

"We are here to get help on an upcoming operation"

"How can they help?"

"There is an agent here I want to get involved undercover, agent David is perfectly suited for what we need."

"I'm sure I can handle it, do we really need this… Agent David?"

"No, not by yourself you can't, think of agent David as a… secret weapon." With that a very agitated Fornell stepped out of the lift with the other agent close on his six.

He didn't understand why he couldn't handle the OP himself, he classed himself as one of the best agents out there and he couldn't possibly think what was so special about this, David person. As he followed the senior agent in front he spotted an exotic, beautiful women standing in the middle of the floor. She was not the kind of girl he would normal go for, but she seemed special, and absolutely stunning. He didn't know when but he would get his chance to talk to her and later on have a drink, I mean how could she say no to me. The younger agent was surprised when Fornell walked right up to her and stood back letting him also have a view of who he was talking to.

"Agent David" The beautiful women span around with a smile on her face as she purred with a heavy accent her greeting, extending a hand.

"Hello Fornell" Her eyes roamed the other agent from head to toe and back up again as a small smile played her lips. "And who is this?" The younger agent was in shock, how could she be a secret weapon, how could SHE be better than him? There was no way she could fight better than him, or shoot or anything needed for an undercover OP. She does not seem to be very musclier or butch, she is elegant and… hot. Is there another Agent David?

"This is Special Agent Ryan Addison." She held out her hand and he took it with a firm grip smiling a charming smile as he flashed his brilliant teeth.

"Nice to meet you" Ziva took in Agent Ryan, he had dirty blonde hair that was slightly messy and bright blue eyes that stood out against his tanned skin. He wore a pair of loose fitting blue denim jeans and a apricot coloured shirt which was unbuttoned at the top with the sleeves rolled up to his elbows. He looked as if he worked out a lot, he had the most amazing body which she could not tear her eyes away from and his smile was ever so inviting. He looked like a male model, but there was something about him that Ziva did not like, although she could not pick it up, just a feeling… her gut.

Tony did not like the look of this guy, especially how he acted when meeting Ziva. The fake charm he put on what was annoying him the most, as well as the fact he looked like a Malibu surfer instead of an FBI agent. Ziva's eyes did not leave him as he stood in front smiling at her with a perfect bunch of white teeth which were a contrast to his tanned skin, also giving him the whole 'surfer look' with his messed up dirty blonde hair. Something about him irked Tony, and not just because he was standing there flirting with his partner; not that he would ever admit that it bothered him.

"How may I ask, is she a secret weapon?" Ziva looked confused at the remark and looked at Fornell with a raised eyebrow.

"She is a lethal weapon, she is beautiful and deadly. Perfect combination for what we need, plus she is a woman." She slightly blushed at the reference but was now more confused than ever. What did they mean by "for what we need?"

"I'm sorry, no offence to you or anything…" he said holding his palms up towards Ziva, "but she is a girl, she can't fight… not as good as I can and why do we need a girl?" She now knows why she had a bad feeling about agent Ryan as her mood suddenly switched into anger.

"Excuse me!" Tony could see what was coming and jumped up between the two of them facing Special agent Ryan.

"What are you trying to get yourself killed?" He looked back confused at why everyone suddenly seems so concerned for his safety and why she was so mad. Fornell sighed before continuing his explanation as to why they needed Ziva working their case.

"She is ex- Mossad Ryan, trust me she is a weapon herself, I have seen her fight. Plus we need a woman for the undercover OP."

"Excuse me, what? What undercover OP have I missed something?" She looked between the two confused as to why they were having a conversation about her she knew nothing about and was getting quite annoyed.

"Tobias, can we have a word please." Gibbs had been listening in and was just as confused as Ziva was; he had heard nothing about an undercover operation, especially since it involves one of his own team members.

"Normal spot?"

"Let's go" The two elder Agents walked into the lift and the doors closed behind them before Gibbs leaned over and hit the emergency stop switch and the lights dimmed as the elevator came to a complete stop.

"What is this about Tobias?"

"What, didn't Vance tell you?"

"Does it look like Vance has told me?" Fornell shook his head as he looked down at the floor.

"Man, I knew that kid wasn't ready to be Director. He said he would brief you."

"On what"

"Your team will be helping us in an undercover operation that involves a serial killer who targets foreign women, so far between the ages of 25 and 40. We have been working on the case for 6 months now and he continues to kill, same M.O. every time. We have very recently caught onto a lead and we think we have the guy. Only problem is we can't get close enough to him without freaking him… we want him alive Jethro and I just think your team can help with that… Plus we haven't got enough evidence to prosecute… and he doesn't seem to be the one to break.

"And let me guess… you want to use Ziva as bait." Gibbs looked away running a hand through his hair as he let out a deep breath. He didn't know if it sounded like a good idea, they had almost lost Ziva before; and the thought of using Ziva as bait for some psychopathic serial killer made him nauseas, his gut didn't agree.

"Jethro, you and I both know she is capable of defending herself… We will have Agent Addison with her the whole time. He is a pain in the ass, but he is good. I understand your concern, but we need to catch this Son of a Bitch."

"How many?" He asked without looking up knowing that the number was quite significant, he had come to ask for help, this guy must be smart.

"12"

"You better hope she doesn't become unlucky number 13." Gibbs leant over and jabbed the button which put the lift back in motion; he didn't want to agree but he knew the director would have something to say about that. Fornell knew this was his reluctant approval and didn't push the matter further, now all they needed to do was talk with the rest of the team.

"But, we are both in this OP together, no one leading, and if anything happens to her I am personally holding you responsible… And you don't want to know what I would do to you Tobias"

"Agreed" The doors opened again onto the same floor they entered from and they walked out to the awaiting faces of 4 very nervous agents.

A.N: I really hoped you liked it, please review and tell me what you think and if I should continue!

Thanks! Keely :o)
