A/N- This is my first NCIS fic, but not my first fanfic. I usually write for JAG or Grey's Anatomy. Anyways, hope you like it.

-NCIS Squad Room- December 22-

Tony sat at his desk and looked across to Ziva. Lately she had been acting strange. Well, she had always been strange, but she was a little more strange than usual. Every time he tried to joke with her about something sexual she would shoot him down. Unlike Kate, Ziva had always played along when he would mess with her, but not anymore. He focused on her face and watched her expression continually changing. She was reading over a report, which is what he was supposed to be doing. "Tony just go ahead and say what it is you want to say." She said annoyed. She pulled her head up so that she could see him.

"What?" he asked as he tried to look like he was doing something. "I don't know what you are talking about. I never have anything to say."

Ziva snorted. "Please, you could talk a goat to death."

"Mule, the saying is you could talk a mule to death." He corrected.

"Whatever; so what does your girlfriend think of your nonstop talking?" she asked with a hint of bitterness in her voice.

"I told you Zee-vah that I don't have a girlfriend." He said as he stood up out of his chair.

"Good, because you definitely don't have time to see her today." Came the familiar voice.

"Right boss." Tony said as he sat back down at his desk. "Ziva was just telling me about her new boyfriend, and of course she assumed I had one."

Ziva giggled. "Okay, so I know that my English is bad, but that last sentence was wrong, no?"

Tony rolled his eyes at Ziva. "I meant to say that I don't have a girlfriend."

"Just like I don't have a boyfriend; perhaps what you said was a Freudian slip. Is that the correct term?"

"Good job Ziva." Gibbs congratulated. "Now do you two think you could be adults for two minutes and tell me what we have on the Peterson case?"

Ziva stood up quickly and beat Tony to Gibbs' side. "Seventeen years ago Samantha Peterson was kidnapped at age five. No ransom note was ever sent, and there was no evidence ever found to help find her. Two days ago her parents were found dead in their condo. The only evidence of who might have killed them was the bloody knife beside Mr. Peterson. Abby lifted two prints off of the knife and ran them on the computer; they belong to Samantha Peterson."

Tony snatched the remote from Ziva's hand and pulled up a picture of a young female sailor and a picture of five year old Samantha. "When Abby ran the prints they matched with the ones lifted from the home seventeen years ago, but they also match with a twenty-two year old Lieutenant Christine Taylor. She is naval intelligence in D.C. She graduated from Annapolis about a year ago."

Gibbs nodded taking it all in. "Where is McGee?" he asked as he walked back to his desk.

"Right here boss. Sorry I'm late, but my car broke down and then I didn't have enough money to catch a bus, so I called my sister and her phone was off and…" McGee stopped and looked up at Gibbs.

"Don't let it happen again." Gibbs said gruffly.

"Right boss."

"Okay I want the three of you to go to the parents' house and look around for while. See if you can find anything that might prove that Christine Taylor is or isn't Samantha Peterson."

"We aren't going to pick her up boss?" Tony asked as he grabbed his gear.

"Do you know where she is Tony?" Gibbs asked annoyed.

"Well I assumed…" Tony grimaced; he knew Gibbs did not like assumptions. "No boss I don't."

"Just for that I am going to let Ziva drive." Gibbs tossed the keys to a grinning Ziva.

"Come on Tony. I can't wait to drive." She said happily as she walked toward the elevator with the two men slowly following her.

"I'm sorry you can't go Agent David."

The three turned around to see the Director standing behind them. "I need to speak with you in my office Ziva."

"Can it wait Jen they are about to look at a crime scene?" asked Gibbs.

"No, Jethro it can not wait." She said with a hint of superiority in her tone.

Gibbs nodded his head toward the Director and held out his hand for the keys. Ziva game him the keys and followed the Director. "You know what that was about Boss?" Tony asked as they got into the elevator.

"No, but I am going to."

-Director's Office-

"Sit down Ziva." Jen said as she pointed to a chair in front of her desk.

"What is this about Director?" Ziva asked as she sat down in the uncomfortable chair.

"I received a call from your last handler, and your old director. It seems that Moussad has asked that you come back. Since you were on loan to us they have every right to take you back. You are being requested for a mission that is tied to the Peterson case. Samantha Peterson was last seen three hours ago in a local Moussad facility, and they want to know why. According to your father she was Moussad, but wanted out. Your job is up to them, but my guess is that you are going there to follow her and get close to her."

Ziva sat silent. "I am going, Director, to kill her."

Jen sat in shock at what Ziva had said. "Ziva you can't jump to conclusions."

"I mean no disrespect Director, but I know what I am talking about. Would you send a trained assassin to follow someone?" There was no response and Ziva gave her a small smile. "When do I leave?"

"Your plane leaves December twenty-sixth. Here is all the information that you will need." Jen handed her a thick folder. "Good luck Ziva." Ziva nodded her thanks and turned to leave. "Oh, and Agent David…" Ziva stopped and turned back to Jen. "Under no circumstance can you inform anyone of where you are going and why. Not even Gibbs."

Ziva nodded and looked at the door then turned back around. "Can I have these last few days to gather my things?"

"Of course."

"Thank you."

"Good luck Agent David. You will be missed." Ziva looked up at her and smiled. Jen could not help but get a bad feeling when Ziva left.

-Squad Room-

Ziva sighed as she gathered the few things that were hers on her desk. She smiled as she pulled out the picture that had been taken of her and McGee. He had randomly taken it one day and then gave it to her. As she looked around the empty room her heart began to crack. She closed her eyes and willed herself not to feel anything. She was a tough agent, not a wimpy woman. Ziva picked up the box and walked to the elevator giving the squad room one more glance, and then stepped into the elevator.

-4 Hours Later-

Tony came walking into the squad room and laid his stuff down. "You know you missed a creepy house Ziva. I mean these people had their daughter's room just like it was when she went…" Tony turned around and saw an empty desk. It was not just empty but clean. Ziva's desk was never clean. He walked over and opened the drawers and found nothing there. She was gone. Without a thought Tony ran up the stairs to the Directors office and barged right in. "Where is she?" he asked angrily.

"Right, thank you so much. Okay, goodbye." Jen hung up the phone and looked up angrily at Tony. "What?"

"Where is she?"

"Gone Agent Dinozzo; she is gone for now. And before you ask all I can say is that she is still in the states for now."

Tony stormed out the door just at Gibbs was storming in. "Jen…" he yelled as he slammed the door. Tony did not stay to find out what was going on. He ran down to the squad room and grabbed his coat. "McGee tell Gibbs I'll be back."

"Tony where are you going?" he asked as he followed him out.

"To find some answers; to find Ziva."

"Is she missing? Tony?" McGee yelled as the elevator doors closed. He sighed and sent a silent prayer to Heaven that Ziva would be okay.

-Ziva's Apartment-

There was a loud knock on her door and Ziva slowly walked to see who it was. The knock came again, but this time it was more of a banging. "Ziva open up or I swear I will kick this door down."

Ziva quickly ran to her door, knowing full well that if she did not open it soon Tony would indeed kick it down. "Tony, what are you doing here?" she asked as she opened her door.

Tony stormed in and left her standing at the door. "What the heck is going on Ziva? I come back and your entire desk is empty and the director won't tell me where you are or what is going on. So I am asking you."

"I can't tell you." She said forcefully as she walked to where she had been packing a few things.

"What do you mean you can't tell me? I'm your partner, I deserve to know." He grabbed her by her arm and turned her around to face him. "Tell me what is going on."

Ziva glared at him. "I can not tell you." She jerked her arm away and went back to packing.

Tony sighed and sat down in front of her. He removed the box from her reach and forced her to look at him. "I'm sorry; please tell me something."

Ziva sat down in front of him and sighed. "The only thing I can say is that I am leaving the day after Christmas."

"That's three days from now! Who ordered you to go? Where are you going?" He stopped and looked at her then gave her a small smile. "Right, you can't say." Tony looked around at the packed boxes. "Does this mean I am going to have to break in another partner?" Ziva nodded and laughed at Tony's exasperated face. "Man, I can only wonder who Gibbs will stick me with this time!"

Ziva playfully slapped him on his arm. "Hey, I was a good partner."

"Yeah, but each time I get a new partner it goes down hill. I mean Kate was a great investigator, but she didn't always like my jokes. You are good at what you do and you help me pick on McGee, the next girl I get will probably suck and have a huge crush on me."

"Oh, like that would really bother you." She said as she stood to pack some more.

"Hey, like you said I must have a girlfriend now." He said as he walked over to help her.

"Look I am not going to argue with you about your social status." She smiled up at him and they stared at each other for a split second. "Can you hand me that box?" she asked as she pointed to a small box near his foot.

Tony picked it up and curiously looked in it. What he found was not what he expected. "Ziva David, you have been holding out on me!" He said as he pulled out a lacy negligee from the box.

Ziva's eyes got huge as she lunged toward him. "Tony give that to me!"

Tony chuckled as he pulled out some more underwear and bras. He looked at one of the bras. "Yeah I am good. I guessed a b and it looks like I am right." Ziva snatched the items away from him. "So do you wear any of these to work?" he asked as he wiggled his eye brows.

Ziva placed them in the box and walked up to him. Her face was inches from his. "Maybe, why do you want to know?"

"Well the other day you had on that nice purple bra I pulled out a minute ago. Just curious if you had on the matching panties."

"Why should I tell you? You said the view was not worth dying for." She leaned in and put her mouth right next to his ear. "Who said I was wearing any panties?" she pulled away and gave him a sly smile. She turned and walked into another room, leaving a stunned Tony to make a mental image.

Tony smiled and followed her into her bedroom. He had been in there before, but nothing had ever happened. He shook his head and tried to focus on the situation at hand. Ziva was leaving, and he didn't know where she was going or why, just that she was indeed leaving. He knew that he would miss her, because she was a good partner and they had become good friends as well. But there was something else that was bothering him. He felt worse then he should; maybe she meant more to him then he knew. A loud thump and then what he could only guess was a cuss word in Hebrew broke him out of his reverie. "You okay?"

Ziva stormed out of her walk-in-closet with a large box in her arms. "Just…oh what is that expression…you know the one about water fowl?"

Tony chuckled "Ducky, the saying is just ducky."

"Ah…that's the one." She set the box down and pulled out a few things. Some of them were books which appeared to be written in Hebrew, but he couldn't tell.

Suddenly a thought came to Tony's mind. "Ziva what are you doing for Christmas?" she shrugged and continued to unpack, or was she packing? He was so confused. "How about you come over to my place and I will make you dinner? Nothing serious, just consider it a going away thingy…you know a chance to say goodbye."

She stood and thought for a moment, then agreed. "What do I need to wear?"

Tony smiled evilly. "Anything that involves that black negligee."

"In your dreams; when do I need to be there?"

Tony was walking towards the door and she followed. "Say about seven, oh and wear something nice."

"I thought this wasn't serious?"

"It's not; I just want to see you in a dress." With his usual school boy smile he left and went to prepare for her departure.
