The elevator ding does not register with the two men sitting at their desk in the squad room of NCIS. McGee plays on his computer, and DiNozzo reads a magazine. A girl gets off the elevator, and moves towards him. Her footfalls are silent. She stops at Tony's desk. She speaks before he notices her presence.

"Excuse me, I was wondering if you could help me."

Tony looks up. The girl, of about eleven, or twelve stands before Tony. He stares at her in disbelief. Her hair is long, and dark. It is braided tightly, stopping a third of the way down her back. Her deep brown eyes stare at him. Her lips barely move as she speaks. She stands perfectly still. Before he can even ask a question, he knows what she's looking for.

"I'm Special Agent Anthony DiNozzo, how can I help you?"

"I'm looking for Ziva David."

"She's off today, can I help you?"

"No, she is the only one who can help me. She is the only one who can stop this."

"Stop what? I'm sorry I didn't catch your name."

"That is because I did not give one."

"Where are you from? Who are you here with?"

"It does not matter."

"Israel?"

"I need to speak to Ziva."

"She is not here."

"You do not understand what is going on. She has to stop it."

"Why don't you tell me your name, and we will go from there?"

"Why does it matter?"

"I am asking. I'm guessing that it's Hebrew for princess, or something?"

"No it's Arabic for, stop asking stupid questions."

Tony looks at McGee who is watching the girl, "Probie remind me what that name is again."

"Don't look at me," McGee replies.

Tony directs his attention back to the girl. "Name, and we can discuss how to get a hold of Ziva."

"I could kill you without you even seeing me move," she reveals.

"What are you ten?"

"Eleven."

"It is good manners to introduce yourself to someone, when you meet them."

"I'm Hannah?"

"What kind of name is Hannah?"

"It is a Hebrew name that blends in to American culture."

"Ok, Hannah, where are your parents?"

"I don't know, I have never met them."

"Why do you need to find Ziva?"

"Mossad is attempting to build an army of assassins."

"To do what, exactly?"

"To kill."

"What do you mean by build an army of assassins? Are they recruiting candidates?"

"No. They don't have to recruit them."

"Where are they getting them?"

"They are growing them."

"Growing them? How are they growing them?"

"From the beginning," Hannah answers.

"I don't understand."

"They are taking genetic material from the worlds best assassins, and putting them together in a lab. They implant the embryos into a surrogate. After the surrogate gives birth the child, or children are taken to a training camp to be raised."

"Without the biological parents knowledge?"

"Yes," she nods.

"This sounds like some sort of conspiracy theory. Why would Mossad do that? How long have they been doing it?"

"It is not a conspiracy. It is real. They have been doing it for a very long time. The oldest is fifteen. He is so well trained that they may auction him off to the highest bidder, in order to continue funding the project."

"How could you possibly know this?"

"Because I am one of them. I am eleven, how else do you think I would be capable of getting from Israel, to here, without anyone with me, without any help?"

"You're serious?"

"Serious about what, DiNozzo?" Gibbs questions as he comes into the room.

"She's an assassin."

Gibbs stops in front of the girl. He smiles, "How old are you?"

"Eleven."

"Eleven? How does an eleven year old become an assassin?"

"I do not wish to be an assassin, that is the problem," Hannah answers.

"Boss this is Hannah. Hannah was just telling me about how Mossad is growing assassins."

"Growing assassins? How?"

"They are some how coming up with the worlds greatest assassin's dna, and creating them in a lab."

"They are trying to grow super soldiers?"

"Yes sir," Hannah nods.

"You are one of them?" Gibbs questions.

"They will come looking for me. Ziva has to stop them."

"Why Ziva?"

"She is the only one who can."

"You are sure that it is Mossad who is behind it?" Tony asks.

"It was Eli David's pet project," Hannah answers.

Gibbs points to Ziva's empty office chair. "Sit," he insists to Hannah. "DiNozzo get a hold of Ziva. McGee, get Vance down here."

"Yes, boss," Tony, and Tim respond in unison.

Gibbs studies Hannah. "Hannah I need you to tell me everything you know."

"There are twenty nine of us. Adam is the oldest, he is fifteen. The youngest, Cain is four months old."

"How did you get here? Who knows that you are here?"

"I used a fake name on my passport. I don't know who knows I'm here, I hope nobody."

"Why did you come here?"

"Eli David is not your ally."

"And Ziva?"

"She does not know the lengths her father has gone to turn her into exactly what he wanted, unfortunately, she is none of them now."

"Ziva's on her way in from the airport," Tony announces.

"Vance is on his way down," Tim adds.

Gibbs nods in acknowledgement.

"Hannah can you tell me any names?"

"Of the children? The caretakers? The instructors? The mastermind? The biological donors?"

"Do any of the donors know?"

"No. None of them consented, either."

"How did Mossad get the opportunity to collect any genetic material from them?"

"Mossad officers often get hurt, and wind up in the hospital. They also quite frequently hit their head, and lose consciousness."

"How did you find this out?"

"They are creating us to be weapons. They want us to be the smartest, and the toughest. They want us to blend in to any situation. Did you notice my accent?"

"Not really."

"That is for good reason. We are trained to speak ten languages by the age of six. Do you know what it is like to think in six different languages? We later focus on major language, and how not to be identified not as a native speaker. We are trained how to be undetected. We learn how to use technology to create fake identities."

"You're saying that they trained you too well?"

"They trained me to follow orders, to not question them..."

"But after a while, any one begins to question."

"Most do not have the need for answers that I do."

"You have names?"

Hannah unhooks the leather bracelet from around her wrist. It has a Star of David on it. She places it in Gibbs hands.

"The star can be removed. Underneath it is a computer chip, it has everything you need to know on it."

"I want to know what brought you here? Why did you choose Ziva?"

"Most of the people on any of these lists, no long exist."

"Exist, or live?"

"Either, both. Most of the ones who still exist, would not be able to stop it. She can."

"Why?"

"When she is angry, she is a machine. When she is infuriated, she is unstoppable."

"You think this will infuriate her?"

"She is one of the names on the donor list," Hannah reveals.

"Did they use all of the donors on the list to create children?"

"No. Some were weeded out. Some were used, but a couple of the children did not meet the standards. Those children were given away, to someone, I have no idea who."

"Tell me about the suitable candidates."

"They would use them until they achieved success. They matched a female up with a male. They only used each match to make one child, in some cases two, but that was only by sheer accident. There are two sets of twins among the twenty nine. They chose the donors carefully. Except for the twins no one has the same parents. That is for a reason."

"They want to use the twenty nine of you to create more assassins? A second generation?"

"Yes," she nods.

"Are all of the donors people who have worked for Mossad?"

"No," she shakes her head.

"Why will Ziva be infuriated?"

"Wouldn't you be, if you had a child that you didn't know about?" she queries.

"Yes," Gibbs admits, "Does she?"

"Yes," Hannah nods.

"I am willing to be that her child is extremely gifted. Would I be correct?"

"She's the only one who managed to make it here," Hannah responds.

"Ziva is your mother?"

"Yes," Hannah nods.

"You are certain?"

"I've read the file. When she was sixteen she was in a car accident."

"You're telling me that Eli removed..."

"She was unconscious for twelve days. He saw her potential, and he decided that she was a perfect donor."

"How old are you?" He wonders.

"Eleven. My birthday is January Third 2000."

"She wasn't even eighteen when you were born?"

"She didn't give birth to me. She has no idea that I even exist."

The elevator doors open, and Ziva steps off the elevator. She stomps to Tony's desk. She drops her bad next to his desk.

"I was getting ready to get on an airplane. Whatever is going on better be good, or you are a dead man Tony."

"I am just the messenger. If you would like to direct your anger at anyone direct it at her," Tony points to Ziva's desk.

Ziva spins around, and looks at the girl sitting in her chair. Tony updates her, "Her name is Hannah, she's eleven, she is from Israel. She has a really interesting story to tell you, and I wouldn't suggest engaging her, I think she could take you."

Ziva stares at the little girl. She furrows her brow, upon realizing that the little girl is eerily similar to her as a child. Ziva steps forward. She extends her hand, "I am Ziva,," she introduces.

"Hannah," the girl smiles.

"Hannah could you give Ziva, and I a moment?" Gibbs suggests. Hannah nods and vacates the seat. She walks over to McGee's desk. Gibbs points to the chair. Ziva takes a seat, and looks at him questioningly.

"What's going on? Where is she from? Who is she? Why is Tony calling me at the airport saying that it's an emergency?"

"She claims that she's your daughter."
