A/N: I'm not a professional writer. I just do this for fun. And now, Act 4.

Gibbs and McGee arrived at Lauren's last known address. "Hello," she stated as she opened the door, "is there something I can help you with."

"I'm Special Agent Gibbs, and this is Special Agent McGee. We're with NCIS. We're here about your recent visit to Dubai."

"I know, and I've been hoping that you would be the one to come, Agent Gibbs. I've read up on you. Please come in." Lauren led her guests to a couch in the living room, then went into the kitchen to prepare some coffee. She brought out a coffee pot for her guests and poured a cup for Gibbs, black, just as he liked it. "I know you're wondering why my fingerprints matched two different names. Obviously, I wasn't originally from Kansas. When I was 16, I met this lady by the name of Hetty Lange. Apparently, she was an old 'spook' in the intelligence business. She learned that I was being specifically targeted by Palestinian terrorists, apparently on a tip from someone inside Mossad. For some reason, she felt the need to save me from this certain death. She deliberately made me miss my bus that day. Just after I would normally get on, the bus was destroyed in an attack. She then took me to the states, set me up with a foster family in Kansas, and established a new identity for me."

"Hetty Lange is now an Operations Manager in our Los Angeles office," McGee noted.

"I made some friends in the intelligence community." Lauren replied. "I got word from a friend indicating that the Palestinians had received information about Mossad operations. I paid him a visit in Dubai, glanced over the information, and knew that it needed to be shared with someone very close to the top."

"Why didn't you contact Director David directly."

"Do you think my father would believe that his baby girl was alive?" she inquired. "I had to prove who I was, That's why I dead-dropped the drive to my father's most trusted team. I figured the bombshell would require him to call in a favor to your director. While my day job is as a dance teacher, I still know a few things about the spy business."

Gibbs and McGee were still shocked over the young woman's revelation. "Would you mind if we brought you to the Navy Yard, and confirm your story with Hetty?"

"I expected nothing less," the young woman replied.

Once again, the Tel Aviv team spent the day sightseeing while waiting for more information. Over lunch, Tony showed the team the photo of the woman they knew as Lauren Sloane, and of the suspicions the Washington team has about her true identity.

Late in the afternoon, Tony and Ziva walked together along the Mediterranean shoreline, hand in hand. "I cannot believe that, after all this time, she has possibly been alive and living in the US," Ziva noted to her best friend and confidant. "After seeing that photo, I am almost sure of it. It's something a sister knows."

Tony nodded in silent agreement. He knew that his technically minded brethren back in Washington had tweaked and tested the photo, and suspected what his partner all but knew in her heart. "If she is who we think she is, I wonder what she would think of us?"

"She would probably like you, Tony. You're witty and fun to be around, even if you can sometimes be a pain in the ass."

"Ziva David, are you actually admitting that you actually like my company?"

The petite Israeli moved closer to her green-eyed Italian partner. "Right now, I couldn't think of a better person to be with."

Upon returning to the Navy Yard office, Gibbs and McGee escorted his guest directly to MTAC. McGee established a connection to the operations center in the Los Angeles office. The call was answered by a young woman that Gibbs was unfamiliar with. "Hello?" she asked.

"This is Special Agent Gibbs in Washington," Gibbs stated. "We need to speak to Hetty Lange. It's regarding a case we're working on."

"I'll go get her," the young woman answered as she left the room.

A minute later, the woman returned, accompanied by a much older woman. "Thank you, Miss Jones," the older woman stated. "Agent Gibbs, how can I help you?"

"I needed to double-check on something," Gibbs responded. "Do you know this young woman?"

Hetty observed the young brunette standing next to the senior agent. "Yes, Agent Gibbs. I saved Tali David from a Palestinian suicide attack back in 2001. I gave her a new identity and placed her with a family stateside. She is a bright young woman, and I thought at the time her future was too promising to lose."

"Hetty," Tali stated, "Whoever targeted that bus all those years ago may be back. A friend of mine had something he needed to share with me. I went to Dubai to pay him a visit. After reading the information that he provided, I knew that the info needed to go straight to my father, so we arranged a dead-drop."

"Why didn't you come straight to me with the information? You do know that Director Vance and your father have a longstanding friendship."

"I know. I just figured this was a better way of achieving the same results. As much as I am thankful to you for saving my life in Israel, I would like to reconnect with my family."

Hetty nodded in acknowledgment. "Agent Gibbs, my office is at your disposal should you need anything."

"Actually, if you could stay on the line, we'll get Tel Aviv on."

Ziva and Tony were back in their hotel room, engaging in sexual foreplay, when the phone rang. The couple got back to business as Ziva answered. "Understood, aba," Ziva replied as she hung up. "Gibbs has something for us, we need to go back to Mossad for a video conference."

"We might want to freshen up," Tony noted. "Lest the boss suspect anything."

The couple quickly took turns showering and got dressed in comfortable work cloths. They met up with their Israeli counterparts in the front lobby. Late evening traffic was fortunately light, and they made it to Mossad headquarters in near record time. "I take it Ziva was driving," Eli commented as the four made their way to the operations room. Malachi and Liat nodded in acknowledgment.

Once in the operations room, Liat opened the connection with Washington. "Gibbs," Ziva stated, "what bring you to contact us?"

"We were able to find our person of interest. She was very forthcoming."

Talia David, also known as Lauren Sloane, stepped forward out of the shadows and into plain view of the Tel Aviv team. "Shalom, aba, Ziva."

*foof*

So... Ziva's sister was saved, and given a chance to live a 'normal' life, by none other than Henrietta Lange. Apparently, the Hamas suicide attack back in '01 was targeted to hurt Eli David.

Now, about the cover identity: I'm a native of Kansas - there isn't that much Navy/Marine activity out here, it's Army turf. (there used to be a Navy air presence out here, however). Tali's alias is 'borrowed' from an old college friend.

I've got Acts 5 and 6 (this story is definitely going to be a 10-act story) in the can.
