"Who does it match up to?"

"Cain."

"Cain? He is only a few months old," Gibbs points out.

"There's more," Abby reveals.

"Like what?"

"The woman he was released to, she was CIA, but has ties with Mossad, specifically Eli David."

"You think that she's a double agent?"

"It would make sense."

"Why?"

"Eli had very specific plans for Cain. He and Daniel, they were born around the same time, for a reason. He wanted them to be close, but..."

"Like Ziva, and Ari he wanted to turn them against each other."

"Not just Ziva, and Ari."

"Mossad against NCIS. Two children both with the potential to go either way, good, or evil."

"If Ari is Cain's father, who is his mother?"

"Eli specifically chose her for several reasons, but one of the biggest, the dead cannot fight any battles."

"Jenny?"

Abby looks at the sleepy baby, in her arms. She then looks at Gibbs, "No. Not Jenny."

He stares at her, in disbelief. He doesn't say it.

"Are you sure?"

"I can't prove it, until I have DNA. Until then, it is just a theory."

"I'll get it for you."

"Are you sure that you want to do that?"

"Why wouldn't I?"

"No one ever has to know. There is nothing that anyone can do. No one has any right to him. Both of his parents are dead, and were, long before he was conceived. Eli is dead, but..."

"He's still pulling the strings."

"What do you want me to do?"

"Call Ziva, see if she's up. If she is take Matthew home."

"Where are you going?"

"Annapolis."

"Annapolis?"

"I've got to talk to Rider."

"Jenny's daughter?"

"They call her the gate keeper."

"Gibbs you haven't asked..."

"I know how Eli's mind works."

"This never has to leave this room."

"She'd never forgive me, if it didn't."

"What is your plan?"

"I don't have one, but I have to do this, for her."

"Ok," Abby agrees.

He finds himself, hesitating, outside of Rider's room. Finally he knocks on the door. A girl with auburn hair answers.

"Agent Gibbs," she smiles.

"Rider?"

"I assume that you have questions you would like answered, and since one of your people killed my father..."

"He was a bastard, he deserved it."

"That is true. How is Hannah?"

"Fine. I am here about Cain."

"Ah, one of your people cracked the code?"

"Is it true?"

"Is what true?"

"Is Ari his father?"

"Yes," she nods.

"And his mother?"

Rider's lips curl into a devilish smile. "I thought it would really set you off. Mossad stealing DNA from your team members, and creating children, one by one."

"Answer me!" his patience begins to wear thin.

"I will answer you, but I have a question for you to answer first."

"What?"

"Why are you doing this?"

"Doing what?"

"Raising a child that is not yours? Does Ziva know the truth?"

"I don't lie to Ziva."

"So you do know the truth?"

"Who does Cain belong to? Who is his mother?"

"Your precious Kate."

"Why?"

"Creating these children, it has caused a lot of upheaval, a lot of whispers. It has caused quite a stir. When the truth comes out, it seems as if no one will be left standing."

"They are still being used as weapons, to bring NCIS down. To tear it apart."

"I suggest that if you want to keep that from happening you tell the truth."

"And if I don't?"

"It's your call, but it would be a shame to watch your team fall apart."

"You're just like him."

"I never had a chance, to have any humanity. My mother did not want me. She cast me aside like garbage. When I met her, she wasn't even sorry for what she did."

"I don't believe it."

"Believe it Jethro. She chose her career over her child. She chose to keep it a secret. She conspired with Eli, to come up with a plan that would protect her. The only problem was that for some reason, he took an interest in me. And you took him away. You let her get killed. You are responsible for all the heartache of all the people around you. You know that don't you? For Ziva, for Tony, for Jenny, and Kate. The worst part is that you don't have the integrity to tell them all the truth."

"Don't," he warns.

"You're driving a wedge between you, and your team. You are tearing it apart, on your own. That is what happens when you lie, even if it is to protect someone. Your lie, it is going to come out, and no one will ever forgive you."

"I had no choice."

"No choice? You always have a choice. Why is living a lie, easier than telling the truth?"

"She asked me to."

"That doesn't make it ok. What you're doing, you are creating a monster. You are no better than Eli. You two, you know that, right?"

"So tell me Rider, your father, he loved you so much, what did he leave you? Did you get the whole empire?"

"Does it matter?"

"I am just curious to know."

"I don't know. The will has yet to be found."

"That's because there is no will. You will get nothing. You have done his dirty work, and you will get nothing, for it."

"Goodbye Agent Gibbs."

He sits in her living room. He stares at the chubby baby in the bouncy seat. The little boy stares back. Hannah and Ziva come down the stairs.

"So where are the two of you going?" he questions.

"To go get lunch, we'll be back in twenty minutes," Ziva reminds him.

"Ok," he agrees.

"Are you sure that you are ok?"

"Ziva I have taken care of him, before. I can handle it."

"Why do you seem so nervous?" Ziva inquires.

"I'm not. It's not like he is mobile, I can't lose him, or anything."

"Are you sure that you know what you want? What you wrote down, that's what you want?" she checks.

"Yes, now please, go get lunch. The boy and I have some very important things to do."

"Like what?" Hannah wonders.

"We've got to watch basketball, and talk about it."

"Right," Ziva nods, grabbing her coat, and heading for the door.

Ziva gets into the car, and turns the engine on. She buckles up. She looks over at Hannah, and waits for her to buckle.

"Seat belt," she reminds her.

Hannah doesn't reach for her seat belt. She turns, and looks at Ziva.

"Something on your mind?"

"Does Matthew really belong to Agent Gibbs?"

"Why are you asking?"

"This is going to get ugly, isn't it? Why would you lie about something like that?"

"Hannah..."

"You know, that I know the truth. I know about my father, and I know about his, too."

"Your father?"

"My father was terrorist."

"Oh."

"You didn't know?"

"No."

"Just like I know, that you are lying about Gibbs being his father. You must have a really good reason. Who are you protecting?"

"Hannah what makes you think, all of a sudden that Gibbs is not his father?"

"It isn't all of a sudden. I have been wondering for weeks. I watch everyone interact with him, and... Gibbs... he has honest eyes, but when he looks at Matthew... something changes."
