Rule number 2 never screw over your partner… Rule number 12 never date a coworker. Those two rules flash through their heads every minute. After their first undercover mission, or "under covers" as Ziva called it, it was clear Tony and Ziva had more then just one little fling.

"Another regular day" Ziva thought to herself. She stared over at Tony analyzing his expression she was dying to know what he thought of her. Gibbs' two rules about "dating" flashed through her head.

When Gibbs went up to MTAC, she crumpled up some paper and threw it at Tony's head. He stared at her, smiled, his you really want to do this, grin, and started rapid fire paper balls at her. McGee gradually turned his head not wanting to know exactly what they were doing, and he definitely didn't want to become their own target. He finally turned his head to see a white ball hurling towards his face. As he tried to swivel his chair back, he lost his balance and watched as his body hit the rock solid floor. Tony and Ziva burst out laughing and watched as he tried to pull himself up, but the chair rushed back and his butt hit the floor with a giant boom. Ziva and Tony looked at each other and almost fall over backwards on the floor.

"Nice work, master Probie Wan Kanobie" Tony chuckled "Show us your agile Ninja moves" Ziva let out a little giggle and Tony played along.

Just as McGee was almost back to his feet, Tony threw his last crumpled bullet of paper back at McGee's head.

McGee rolled his eyes and said "Grow up Tony"

Ziva chuckled and sweetly replied "McGee you have to find some humor in this"

"Of course you would say that Ziva" McGee replied his voice strained and annoyed "You weren't the one who got hurt"

Tony burst out laughing and shouted over to Ziva saying "I Think we've hurt are little McGoo's ego Ziva".

Ziva sat down and laughed then replied "were sorry if we have hurt you egg-o McGee".

"No" Tony chimed in "egg-o is a brand of waffles, you know Lego my egg-o"

"What" Ziva replied confused.

"I'm glad you've gotten so much work done Dinozzo" shouted Gibbs.

"Ziva started it boss" Tony shouted back.

"McGee" Gibbs exclaimed "Why are you on the floor?"

"Tony knocked me out of my chair boss" McGee whined and then shot a gotcha look at Tony.

"I did not" Tony moaned. "Ziva threw that paper wad not me".

"I don't care who threw what!" Gibbs commanded. "Pick up the paper and get back to work".

"Yes boss" everyone chimed.

Ziva stood up and went by Tony's desk to help him pick up the tattered remains of their paper war. Ziva nonchalantly squatted down by Tony and started to help him pick up the scarps of paper littered across the floor.

"Nice work my crazy, Israeli" Tony whispered.

Ziva felt her cheeks turning red. She slowly reached her hand across Tony to pick up a piece he missed. Tony looked down and stared at Ziva. She could feel his eyes checking her. She swiftly pulled body back brushing her hair against Tony's face. Tony pretended that he had some of her hair in his mouth and brushed Ziva's hair back slowly letting his hand graze Ziva's cheek. She looked straight up at him and almost lost her balance. His bright green eyes were locked with her and she could feel the tension between them. As she tried to stand back up, she slipped. She braced herself ready to hit the ground, but as she opened her eyes she could feel Tony's warm hands across the small of her back. She was only five inches from the floor and she could feel her heart beating faster.

"Hey! Aren't you guys done yet?" Gibbs shouted severely annoyed.

Tony, shocked from the break in the silence, dropped Ziva to the floor.

"Ow" Ziva chuckled.

Tony was so embarrassed he could feel the blood rush up to his cheeks. He couldn't believe he had ruined that moment, but the awkwardness didn't last. Ziva looked back at Tony with her gorgeous smile and the both cracked up laughing.

Gibbs rolled his eyes and barked at them saying "Would you two cut the crap and get back to work".

Tony grabbed Ziva's hand and helped her up. Gibbs stared at them ready to shout and the both rushed back to there desk, clumsily shoving their body's down into their chairs.

By seven it was getting dark out and Gibbs was packing up for the night, Ziva leisurely finished putting her work away and headed for the elevator.

She slowed her pace and shouted "good night" to the rest of the team. She heard a jumbled mess of words. McGee shouted his sincere "Have a nice night", she could her Tony's "See ya later Ziva." She smiled once she heard that; his voice was so crisp and clear like he planned how to speak to her. Her heart would always skip a beat after his good byes. Gibbs mumbled something from the lines of "I'll see you here at eight hundred" or it might have been "I'll see you here tomorrow Ziva". She wasn't too concerned about which one; he clearly was absorbed in some other work.

She swiftly smacked the elevator button with the palm of her hand and waited for the ding. She took one smooth step in and hit the down button. The doors were barely open when a hand slid in the door and Tony popped in with a toothy smile. He hit down again and suddenly turned around. Ziva was a little startled she stared at him and his smile turned into his curious face (as she liked to call).

Tony took a bow and in a fake voice said "My apologies to the lady."

Ziva rolled her eyes playfully, and Tony smiled knowing that his goofy voice had worked. As Ziva and Tony neared the bottom floor, the elevator reared to a halt.

"What just happened" Tony shouted in an utterly confused voice.

"I don't know" Ziva replied briskly sounding a bit annoyed. She immediately regretted it she could see Tony's eyes fade and she knew that she had hurt him in some stupid way.

"Sorry" Tony replied in a mocking tone "I guess you know why we're stuck here".

Ziva looked down at the ground and thought for a moment her mind was racing. "The power most likely went out Tony" Ziva said.

"Really" Tony replied sarcastically "I wouldn't have guessed."
