A/N: Well, I have been having an NCIS season 3 marathon! I noticed in 3x20 Untouchable that Ziva offered to teach Tony piano again, and it prompted a fic. Yay! I'm also beginning to think that this is the reason why the surveillance photos in 4x01 Shalom showed Tony being at Ziva's house. I bet she was teaching him piano :)

Ziva sat at her desk, her pencil poised over her paper to sign off the accident report. She wasn't angry at herself, in Mossad it had been an accepted tactic, ramming a suspect's car wasn't a serious error. It wasn't encouraged, but no one complained. Well, except possibly the owner of the car but they soon got over it.

She was the only one left in the bullpen. Tony had dashed out as soon as Gibbs had let them leave and McGee followed shortly after.

"Are you going, Officer David?" Gibbs asked expectantly.

"I just need to finish off my report," Ziva answered, not meeting his eyes.

"Okay then," Gibbs conceded that she wasn't going to be talkative. Ziva only looked up when the elevator doors shut, leaving her alone in the darkened bullpen, the only light was the miniscule amount emanating from her desk lamp.

Ziva had to admit, being at NCIS was a welcome break from Mossad. Oddly, she felt more at home in the foreign country than her homeland. Ziva realized that if she had to return to Israel, she would miss McGee, Tony, Gibbs and Abby.

The sharp ding of the elevator doors opening startled her out of her reverie.

"Tony," she exclaimed, slightly confused. "Why are you here?"

Tony shrugged. "I guess I could ask you the same question," he answered.

"I was finishing my report," Ziva retorted stonily and Tony rolled his eyes.

"For two hours?" he asked skeptically and she glared at him. He grinned. "Well, since you're still here, I may as well ask you it anyway."

"Ask me what?" Ziva questioned him suspiciously.

"Your offer, earlier," Tony began, "when we were surveying Roca."

He studied her expression carefully to see if she had any recollection of it at all but her face didn't change. After all, Tony supposed, she was trained to keep her expression neutral.

"About piano," he added nervously, "about teaching me?'

Ziva's mouth curved into a smile and Tony took it as a sign to keep going.

"I was wondering if you would. Teach me, I mean," Ziva had never seen Tony nervous, and she wondered why asking her to teach him piano made him worried.

"Of course," she smiled at him, "I would love to."

Tony looked massively relieved and Ziva continued.

"Would you like to have dinner tonight? Maybe I could teach you a little as well," she added and Tony smiled.

"Grazie mille," he grinned and she laughed.

"A lo davar," she replied as she grabbed her bag and swiftly signed her name on the report before locking it in the second drawer at her desk. She picked up her bag from where it was lying on the floor and removed her coat from the back of her chair, draping it over her arm.

"You'll be needing that," Tony advised and Ziva looked at him skeptically. "No, seriously, it's quite cool outside."

"I'll be fine," Ziva replied stubbornly and Tony shrugged.

"Suit yourself," he conceded as they headed towards the elevator together after Ziva had flicked the switch of her desk light to 'off.' They waited in silence for the elevator to arrive and when it did they still didn't say anything to each other. All conversation seemed to have left with the light from the desk lamp.

Tony moved out of the way for Ziva to go in first, and she smiled at him. For all his ogling of girls and his immature ways, he could be a gentleman when he wanted to. The doors closed on them and Ziva leaned against the cold steel wall as the elevator descended. Suddenly, the lights went out and the elevator stopped. She glared at Tony and tried to flick the switch back on but he had positioned himself right in her way and she simply found herself pressed up against him in a slightly provocative position.

"Tony," she growled, still attempting to reach the flip switch. The man blocking her way simply grinned at her. "Move!"

"Not until you tell me why you stayed in the bullpen until ten o'clock," Tony retorted and noted how Ziva stopped struggling against him.

"I had to finish my report," Ziva answered, as if it was the most obvious thing in the world. Tony raised one eyebrow.

"You finished it when I was there. It took you – what – five seconds? Not three hours," he reminded her. Ziva shrugged. She wasn't going to tell him why she was still there. She wasn't going to tell him who – or what – she was remembering. She would never, ever tell Tony about that fateful night in Gibbs' basement. Ever. Gibbs was the only one who knew and it was going to stay that way.

"Fine. I was debating about whether I should just go and hand in my notice and go back to Mossad or whether I should wait until they arrest and fire me for dangerous driving," Ziva replied, smiling innocently at Tony. He moved out of the way and she restarted the lift. She wasn't sure if Tony had simply accepted her answer or whether he truly believed her. She doubted that it was the latter.

The rest of the elevator ride was in silence and when they reached the parking lot Ziva began to head off to her own car.

"Ziva!" Tony called after her and she stopped and turned. "We're both going to your place, why don't we just take one car?"

"You hate my driving," Ziva answered as she walked back to him.

"I didn't say that I'd let you drive," Tony grinned as he plucked her car keys from her fingers, resulting in him being on the receiving end of a strong punch to the shoulder. He yelped in surprise. "Hey!"

Ziva grinned and tried to grab the keys but his height allowed him to hold them above her head, just out of her reach. Ziva jumped to grab the car keys but as she did Tony leaned backwards to keep the keys out of the way of her taking them back and as she fell back down she landed on him and they both tumbled to the ground.

"Why are you on top of me?" Tony asked, smirking. Ziva jabbed him in the stomach and he groaned.

"Give me the keys and I'll get up off you," Ziva informed him and he raised his eyebrows.

"I quite like it how we are," he said as he smirked. His grin faded. "Uh, hi Gibbs."

In the moment that Ziva took her eyes off him to see if it was Gibbs, Tony slid out from underneath her and ran over to her car, unlocking the driver's door and getting in to start the car. Ziva jumped up, annoyed at being so gullible.

Dejectedly, she opened the passenger door and sat down, shooting Tony a death glare.

"You just had to sign another accident report, sweetie," Tony smiled innocently, "there is no way that I am letting you anywhere near the wheel."

"Call me sweetie again," Ziva replied, "and you will find that wheel inserted where the sun-"

Tony accelerated away before she could finish her threat.

A/N: Reviews would be awesome! Thank you!

By the way, 'grazie mille' means thank you very much in Italian, while 'a lo davar' means you're welcome in Hebrew.
