Disclaimer: I own nothing of NCIS or its characters, obviously. The mistakes are a different story.

A/N: Last chapter I forgot to thank all the people who read this story. This was meant to be the last chapter; but it turned out to be longer than I expected, so I'm going to make two out of it.

Thanks to everyone who reviewed it. That meant a lot.

Chapter 7

I'm still the best

A lot of things crossed Ziva's mind. At one point in her life she was Mossad and being aimed with a gun in a crowded place did not use to terrify her, but now, she belonged to NCIS and the idea of fighting back the guy inside the bar risking everybody inside was not her best option. But as long as she stayed inside the bar, she was going to be safe. Surely the terrorist did not want to get anybodies attention, or he would have already shot her or at least show his gun a bit more. So she chose to talk instead and buy herself some time.

"Why are you so sure that I kill Ari? I had no reason to do such a thing like that"

"You had more reasons than you think. You're Mossad; he was Hamas, which is the most important reason. He was Hamas' mole and you found out, when he was caught and refused to talk, you decided to kill him"

At that point Ziva realized that the blond man had not the slightest idea on how did Ari die.

"Ari was never tortured, he was shot, and you're right I did it, but not because I found out that he was a mole but because I was trying to earn somebody's trust".

Ziva was now smiling internally and was confident that things were going to turn out the way she needed them. At the end of the day all men are the same, so maybe if she convinced him that she killed Ari because she had to in order to get something and not because it was her duty, then he was going to believe her when she told him that she was willing to become part of their cell, and betraying NCIS was not going to be a problem at all.

"And just for the record, Ari was my brother, so there is no point on being threatening me with that gun, I'm not afraid. If you want to kill me, then go ahead and do it but, on the other hand, if you still think that I'm useful to your organization, then stop this silly game and lets get down to business".

"Why do you want to do that? I do not trust you". The blond man said.

"I do not trust you either, but we need each other if we want to pull through. You want to become a part of Hamas, and I want to get rid of my life. I do not want to work for NCIS anymore, thanks to your stupid friend I've lost my husband for good and I have nothing to loose, but, everything to win. So, tell me…"

"Armand"

"…Armand, what is your choice, do you need me or don't you?" Ziva said, one of her fingers playing with his arm.

"So thanks to Amin you lost your husband?" he said in a seductive voice that made Ziva feel sick to her stomach.

"No, thanks to him, I'm free now to do whatever I want, which is different".

"So, then a good drink is in order, why don't we celebrate and then we go to talk to the other members, I'm sure they would like to meet you, and maybe, just maybe, you will convince them that killing you is not a good idea after all".

"Ok, I like the last part, but the first one, I do not like it very much. NCIS thinks that that I'm devastated because of my marital situation, and if I disappear just like that, they're going to try to find me. My husband is not going to stop until I signed the damn divorce papers and those are obstacles.

I have a better idea, you're going to let me get back home, I'll sign the papers, leave a note and then I'll be free to join your organization. And, if I ever need to get back to NCIS in order to fulfill our purposes, then I'll be free to become your mole without any suspicion, what do you say?"

"I do not like your idea; you can be playing me in order to buy some time. I'll say it again; I do not trust you David"

"Then we'll do things your way, but if NCIS finds us, it is going to be your fault, and kiss Hamas goodbye, because once you, me and the rest of the organization will be locked down in a federal prison, that will be the end of your dreams of becoming one of Hamas cell operating in America, your choice…Armand"

"You have one hour David, and we'll meet here. If you do not come you future ex husband is going pay for your betrayal"

"Fair enough" With this Ziva stood up and left the bar.

Fifteen minutes later, Ziva got into Jenny's house, even when she tried not to make noise, a voice from behind told her she failed her task.

"What is going on Ziva?"

"Oh!, I would have expected Jenny's voice considering this is her house, but this is a surprise, what are you doing here Gibbs?"

"I sent McGee to the bar to keep an eye on you, he told me that he saw you enter into the bar, but he never saw you leave, what happened?"

"I do not have much time, I have to get back to the bar, all I can say is that we are close Gibbs, a man found me at the bar, his name is Armand, or so he said, he belongs to the organization, he knows everything about me, he went to the bar to took me hostage"

"What a hell…"

"They do not want to sell weapons anymore Gibbs, what they want is turn me in to Hamas, and tell them that I am Ari's killer, so they earn Hamas trust"

"Did you…?"

"No", she said shaking her head, "I did not tell him, nor Amin, I do not know how did they find out, but they did. Listen to me; I made him think that I'm willing to betray NCIS in order to become part of their organization. I told him that Ari was my brother, that certainly shook him a little, he was not expecting that"

"Why did you do it?"

"My cover was blown; I had to think of something, which I did, I'm in the game now and more than ready to play it"

"What do you mean?"

"I'm going undercover Gibbs, I have to meet Armand at the bar in less than 30 minutes, I will try to be in contact, but if you do not have news from me in a couple of days, do not worry, I'm going to need some time, to get to know how thy work, what do they want, the kind of surveillance… before I will be able to make contact"

"No, I won't let you"

"It is not your choice Gibbs, it is my mission, before my accident, you did not even know that I was working undercover. I started this, I ruined it and now I'm finishing it, whether you want it or not. It is a unique opportunity to bring down an arm dealer's organization, and maybe some Hamas cells, which is more than we can expect on a regular basis."

"What about you, DiNozzo, your lives?"

"What about it? There's nothing Gibbs, before Tony I was Mossad, an officer, an assassin, after Tony, I'm still the same person, maybe not as skillful as I used to be, but I'm the best for this job and you know it. Wish me luck, yes?"

"Ziva, you do not have to do this, we can…"

"No, there is no time Gibbs, if I do not do it, they are going to be after me, and all my loved ones, I do not want that. Please give Tony this", she said giving Gibbs an envelope. "I've already signed them. See you" She smiled lightly and gave him a quick hug, which he responded and then she left.

Gibbs stayed in the living room thinking, he knew this was not a good idea, but he could do nothing, she was determined and made up her mind long before she even talk to the guy at the bar.

The next day everybody were at NCIS, Tony started to wonder where was Ziva, it was 9 am and she was nowhere to be found, the director was already there, but, Ziva? He did not want to be worried, and he definitely was not going to ask Gibbs, his ego did not allow him to do that, not after their conversation the night before.

The day went by without complications, no new cases, just reports that needed to be done. By the end of the day, nobody had mentioned Ziva's name, and that was more than weird, because not even Gibbs asked anything about her. That was when Tony made up his mind and decided to ask about her.

He cleared his throat "Boss, do you know where is Ziva?", Tony asked, pretending that he did not care.

"Nop"

Tony and McGee looked at each other, confusion written across their faces

"But the day is over, I mean, almost over, and she did not show up for work, is she sick?"

"I really hope not DiNozzo, but you saw her yesterday, did she look fine to you?"

"I don't know"

"Then what happened to her?" McGee asked

"She went undercover agent McGee", Jenny's voice came from upstairs. "And we will not know something until she contact us"

"What?" Tony and McGee said at the same time. Jenny's words definitely took them off guard.

"But, but when someone is undercover, we usually keep in contact with", said McGee. Tony was too shocked to say anything.

"She did not give us time to do that McGee, by the time she made up her mind, she had only 30 minutes before her meeting.", said Gibbs standing up from his chair and walking toward Tony's desk. "She asked me to give you this", he said giving Tony the envelope.

"All we can do now is to make sure that she comes back to us in one piece"

"And how are we going to do that boss, we do not even know where is she" said McGee

"By looking into the information that we have about this organization and investigating everything we can about them, their connections, everything", said Jenny.

For a moment Tony disconnected himself from the conversation, he was staring at the envelope, afraid of what he might found inside. After a couple of minutes, he finally opened it. There were the divorce papers, signed and a note attached to them: I'm sorry Tony; I never meant to hurt you. Love you, Ziva.

"She did it for you DiNozzo, for all of us, those men knew about Ari and they threatened her, if she did not join them, they were going to hunt her beloved ones down"

"But, how did they found out" Tony's word were almost a whisper, he was so worried and he knew that if he raise his voice, everyone would notice that he was about to cry.

"I do not know DiNozzo, I do not know"

Suddenly, Gibbs' words from last night came to Tony's mind…I hope that by the time you realise that you're making a mistake it is not too late…
