A new chapter is ready to be read! Here you go :-)

Suddenly, the world seemed to stop for a moment.
"What?", Tony quietly answered, not sure if he heard her right.
The brunette looked at him dead serious, "I shouldn't have told you, but... you probably would've found out anyway, if the mission turns out to be a success."
"Ziva... she can't be."
"But she is. The Mossad has wanted to get information from our Navy for years. So they sent her. It's the truth, Tony."
"No, I don't believe it", he seriously replied.
"Why?"
The man looked at her, anger boiling inside him, "I know Ziva. She quit the Mossad for good. She didn't wanna work for them anymore. She wanted to work for NCIS and so she did. You can't just come here and tell me that's all a big joke."
"Tony...", she tried to calm him down.
"Kate", Tony looked at her, more serious than ever, "It's been a long time and Ziva took your job. I can understand if you feel jealousy towards her-"
"What?", Kate indignantly asked, shocked about what she just heard.
"It's okay, really."
Kate shook her head, "I'm not jealous, Tony. I'm serious, there's a difference. Why can't you believe me?"
"How would you know anyway. I've been working with her. Maybe that was the reason she started working with us, but she stayed and became part of our family. You just don't want this to be true."
Silence came between the two. Kate looked at him in disappointment, "This is why I shouldn't have told you, and why I didn't tell you earlier. This is exactly one of the reasons no one from the team was supposed to work with us on this mission. Anyway, I thought that I should still tell you because you deserve to know. I guess I was wrong. But now I can't take back what I told you. Though, since you don't believe me, it shouldn't be too hard for you to still concentrate on your job tonight, not telling anyone what I just told you."
Finishing that, Kate got up and left, leaving a confused Tony in the living-room.

When she arrived home, Kate quickly changed into her pajama before lying down in her comfortable bed. She knew she could get into trouble for telling Tony about Ziva. After all there was a chance that the mission wouldn't go according to plan and with that, Tony would return to NCIS as if nothing happened. She knew that that would've been hard enough for him, just knowing that she was still alive. But now, knowing Ziva's secret, it would be even harder for him. Besides her not being allowed to tell Tony, Kate never wanted to tell him anyway because she knew he wouldn't believe her. But at the same time she had felt bad, not telling him. Now it was too late to go back. Her words were said. All she hoped now was that it wouldn't distract him from work too much.

It was two in the morning, when an upset Anthony DiNozzo walked into Abby Sciuto's laboratory, trying his best not to show his emotions. McGee was already there, doing something Tony couldn't see on the computer.
"There you are", McGee greeted his colleague, turning around when he heard the footsteps.
Tony stayed silent, stopping in front of McGee when he got there.
"So, why did you call me here?"
"I need you to hack into the computer of a security service."
"What security service?"
"Mossad", Tony emotionless answered.
McGee raised his eyebrows in surprise, "Mossad?"
"Did I stutter, McGeek?"
"What for?"
"You can do it, can't you?"
McGee looked at him for a while, "I can try."
"Try?", Tony asked dissatisfaction in his voice.
"I can do it, Tony."
Tony shortly smiled, "That's what I needed to hear."
McGee kept looking at Tony for a few more seconds, until he turned to the screen and started typing codes.

While McGee was trying to hack into the server of the Mossad, Tony sat there behind the screen, lost in his thoughts.
"She seemed so serious", he thought, thinking back of his earlier conversation. He wanted to believe what she told her, but he couldn't. Kate meant a lot to him and the fact that she wasn't dead improved his life more than he thought it could, even though he never did think about it. But Ziva as well had grown close to him. They were all a family. No one could possibly not be who they said they were. That was impossible. All the memories he and Ziva shared together. It couldn't have been for nothing. She couldn't have doing this for reasons.

"Tony... Tony", McGee jolted Tony out of his thoughts.
"What?"
McGee looked at him with concern, "What is wrong with you?"
"Excuse me?"
"That's not how I meant it."
"But it sounded like it to me."
McGee sighed over that comment before explaining himself, "What I meant was, you seem a little off. And don't tell me you're tired, because that's not it. Something is bothering you, isn't it?"
"It's an important mission, okay?"
"I don't think that's what bothers you."
"Do your job, McGee."
"You've changed somehow."
Tony looked at McGee with interest now, "What's that supposed to mean?"
"Ever since you started being part of that secret mission you started acting different. It didn't seem to be somehow negative, but now..."
"Now what, McGee?", Tony sulkily asked.
"Now you're just pissed."
"It's a stressful job."
"You don't have to tell me, but you can't deny that you're a bad liar."
Tony stayed silent, not knowing what to say. After all, McGee was right. Yet there was nothing Tony could say. It would probably feel good telling someone about it, however, he knew he wasn't allowed to do so.

As time passed by, Tony felt himself wanting to sleep and somewhat tired, though at the same time, he was wide awake. There was too much on his mind to be able to fall asleep. Of course he couldn't fall asleep anyway, since McGee was still trying to hack into the Mossad's system.
Fortunately, McGee left Tony his freedom and didn't bother him with more questions. He knew Tony too well to waste his time asking him questions to which he wouldn't get an answer. McGee could feel that Tony wanted to talk about it, but something was stopping him. And since he had a job to do himself, he didn't spend much time thinking about it.
"How much longer, McGee?", Tony asked half asleep.
Without taking his eyes off the screen, he answered, "It's far harder than I expected it to be..."
"How much longer, McGee?", Tony repeated his question.
"I don't know", he sighed.
For a few seconds, maybe a half minute, there was silence between the two until Tony asked, "How late is it?"
McGee quickly checked his watch, "Three."
Tony tiredly groaned.
"That's not very helpful, Tony."
"You're obviously not that helpful either, Timmy."
McGee rolled his eyes, "Without me you wouldn't stand a chance."
"Who says that?"
"Everyone who knows that you're not any good with computers."
"That's not true."
"Oh, really?"
Tony nodded, "I'm better than Gibbs."
"What an achievement", McGee sarcastically replied.
"If he knew you said that, he'd shoot you right away."
"But firstly he'd make you tell him why you're ordering me here in the middle of the night."
Tony ignored that last comment, giving McGee time and space to concentrate on his job again.

A little more time passed, and so it was half past four in the morning.
For the last ten minutes, Tony had walked around the lab, trying not to fall asleep. He thought about all kinds of thinks just so he wouldn't fall asleep. At the same time he regretted that, due to all of his thoughts leading to the same - his last conversation with Kate. It completely messed him up, he couldn't think clearly anymore. Nothing made sense. He simply wasn't sure about anything anymore.
Finally, his thoughts were interrupted by a now happy-seeming McGee, "I did it", he said, not believing himself.
Tony quickly jumped next to McGee, starring at the screen as well, "Good job McGee."
"So, what exactly are you looking for?"
Tony looked at McGee, "Do I still need you? Cause if possible, I shouldn't tell you."
"Well, technically, you don't need me. But it would be better if I did everything since someone has to shut down the computer and getting rid of all kinds of evidence of us being here. Plus, who knows what you might do if you search around in their main server."
"Thanks for having so much faith in me", Tony smiled sarcastically.
"I just don't think you'd want anyone to find out what we're doing here right now."
Tony sighed, "You're right."
McGee looked at him patiently, waiting for Tony to explain things to him.
Tony looked at McGee before starting to explain everything, "Look, the Mossad may or may not be in the possession of information concerning the US security, especially Naval information."
"Are you serious?", McGee asked in disbelief.
"No, I'm practicing for my new job as a comedian", Tony said ironically, "Yes, I am serious. Dead serious. So would you just help me do the things you do and stop asking me more questions about all of this?"
McGee nodded, "Whatever you say."
And with that, the two started looking for stolen information.

Hope you enjoyed this little chapter and I'll give my best to post the next chapter as soon as possible :-)
