Tony looked up from the paperwork he was filling out. Ziva was across the way, head bent forward, dark hair spilling in front of her face as her pen furiously scribbled across the paper.
The room was dark; the ceiling lights had long since been turned off, and they were working by the light of their desk lamps and computer screens. Gibbs and McGee were gone, everyone had gone home except for the two of them, stuck filling in the paperwork on why they had discharged their guns during the case (Tony had been tempted to write something along the lines of "Next time I will let the armed suspect escape and spare everyone the paperwork" but Gibbs had quickly put the kibosh on that).
He leaned back in his seat and watched as she shuffled her papers into order, the warm glow of her computer casting an ethereal light about her. "You know, Ziva... The lights are dim, the room is empty. The perfect setting for..." He let the statement hang as he wiggled his eyebrows and flashed a winning smile.
She bent down to pick up her backpack as a seductive smile slid across her face. "Mmmm Tony, I would love to..." She wiggled her eyebrows back at him and he flashed a 1000-watt grin. He got up from his chair and moved around to the front of his desk, leaning back and crossing his arms. She slowly closed the distance between them, slinking forward until they were only a couple of feet apart before she stopped. "Unfortunately, we have an early morning tomorrow and I have a hot day with my bed." She turned to leave.
"Hot day? Date. You have a hot date... With your bed." He grabbed her hand before she could escape, pulling her closer to him until she was only inches away from his face, his hot breath brushing her hair. "Sounds exciting. Can I watch?"
She quirked him a half-smile that made his heart race, and for a minute, he could swear she was moving ever so closer to his face, her body rubbing up against his, their lips almost touching...
With a small sigh, she moved away. She gazed at him for a moment longer, the smile still lingering on her face, and then turned to leave once more. "Goodnight Tony."
He watched as she walked away, until she was almost at the elevator, and then called out once more. "Ziva... Wait." He thought hard for a minute, before spitting out "Yom huledet same'ach."
As soon as he said the words, he cringed. Even though he did not speak Hebrew, he could tell that the pronunciation was way off. He had spoken too quickly, he had tripped over the words, he had mumbled, he had butchered the words beyond recognition, he had... Made her smile. She was smiling. She looked radiant as she beamed at him, grinning from ear to ear, beyond happy. Sweet, I was actually coherent. Maybe I should look into this Hebrew thing, might go over better then the French my mother tried to make me learn...
"You are very sweet Tony. But my birthday is not until tomorrow."
He pointed towards the clock on the wall. It read 12:06 am.
She turned back towards him and gave him another smile. He loved seeing her so happy. In this line of work, it was very easy to be dragged down, to let the death and anger and despair get to you, muddle with your head. Tony knew all to well. He tried to be a beacon of light for his team, someone who was always upbeat, always joking, always trying to put a smile on his friends' face. But with Ziva, Tony discovered he could do more, be more. He didn't have to say something idiotic to make her smile. He could be sweet. He could be genuine. He could be himself, and she seemed to be happy with that.
"Thank you, Tony" she whispered, and then the elevator doors opened and she stepped inside. Her eyes sparkled as she looked across the empty space to where he stood. "See you tomorrow."
