A/N: This is my first fanfiction for NCIS/Tiva ever. It was inspired by "Who'd Have Known" by Lily Allen (cute song if you're interested in looking it up). Hopefully I did both the Tiva ship and Lily Allen justice. Unfortunately I do not own NCIS or Lily Allen's song, but I do own all errors – so I apologize, I pumped this out in about thirty minutes. Good or bad, I appreciate hearing what you think. Enjoy!

The room was dim and warm, the couch was comfortable, and frankly, Ziva was having a hard time keeping her eyes open. Her eyes flicked over to the clock. No wonder she was so tired, it was five in the morning. Tony stretched in his massage chair just a few feet away. They had been talking all night long, and suddenly, whether they ran out of things to say, or their minds were just too tired to keep the conversation going, they had fallen into a comfortable and comforting silence. That is, until Tony yawned loudly, without even the most minute attempt to stifle it.

"Am I boring you, Tony?" She quirked her eyebrow at him.

"I'm just exhausted, I think I'm gonna hit the hay soon." Ziva stared at him, an slightly amused, but confused look on her face. "I'm going to go to bed soon," he clarified.

"Ah, that sounds like a good idea, much better than your chair. Much easier on the back, yes?"

Tony groaned as he stood up out of his chair, and collected the wine glasses off of his coffee table. Ziva watched as her partner detoured to the kitchen, and quietly rose from her spot on the couch and walked into his bedroom.

It was dark, but she didn't bother turning on the light. Her eyes adjusted to darkness quickly, and she had been in here often enough that she could navigate it blind. Slipping under the covers, she wondered if he would actually join her tonight. These past couple of nights he had been sleeping in that stupid armchair of his, and before that, he had taken the couch.

She closed her eyes, hoping to find sleep sooner than she usually did, but knew that she would be listening as Tony moved around the apartment. She heard him turn off the lights in the kitchen, double check the lock on his door, and turn off the lights in the living room, and finally, she heard him walk into his bedroom, and slip under the covers next to her.

"Maybe we'll have the day off tomorrow," he whispered, his voice low as he wrapped his arm around her shoulder, moving close to her beneath the covers. As if the room had suddenly dropped ten degrees, Ziva turned in his arms so she was facing him, and snuggled closer. "It's still snowing out."

"I don't think Gibbs gives days off for weather conditions," she chuckled, her breath hot against his neck.

"He should," Tony grumbled, his voice becoming more and more drowsy as he began to fall asleep. "Tomorrow would be fun." He pulled her closer to him. "We could watch an old movie, A Place In The Sun with Montgomery Cliff and Elizabeth Taylor…perfect way to celebrate Snowmageddon…" his words began to become incoherent, and in his equally drowsy state Ziva could not figure what he was saying, or where this was going. She closed her eyes, finding comfort in his nonsense words. "Ziva?"

"Can I help you?" She opened her eyes, her fingers scratched lazily across his stubbly cheek. He reached over, and gently touched his lips to hers once, and then twice a little bit a longer, and a third time when she began to respond to his kiss.

"G'night, Ziva," he said quietly, pulling her closer.

"Goodnight, Tony."

For the first time in her life, Ziva was having a hard time focusing on her work, but it was a dull day and there wasn't much to do anyway. It seemed like every five seconds or so she was glancing up to see what Tony was doing, which usually involved both of them looking down, attempting to get back to work. Her thoughts were twirling – was that the correct idiom? – and she could not get them to settle back down.

Yes, she and Tony had effectively grown closer. Yes, they had shared a bed in Paris. Yes, he had kissed her. But were they together? She cursed herself for thinking about this so much, it should be simple. The facts were that she had been spending most of her nights at Tony's apartment, she brought the wine, he provided the movie, and that was that. Two friends, enjoying a movie night. And lately, sleepovers. But it was all innocent enough.

She wished that she could talk to Abby, but she knew that would lead to McGee knowing, and that would lead to some very uncomfortable moments, which would inevitably lead McGee to experience an uncomfortable amount of pain at her hand. She couldn't do that.

The buzzing of her phone against her desk snapped her out of her thoughts, and she opened it to see who was contacting her. She smiled. Tony. Whenever his name lit up on her phone she always seemed to smile. She opened it quickly, read the message, and glanced up before responding and then promptly acting like nothing had happened at all.

If nothing else, even a simple message from him "firming up" their plans for the night, made her feel less alone.

It had been days since Ziva had been without Tony. Between working with him and staying with him every night, she had grown accustomed to being around him the majority of her time. For better or for worse, she was stuck with him.

The kiss that they had shared a few nights ago had multiplied and become deeper and stronger and more dynamic. She had been surprised when he started to touch her hand as they stood next to each other a crime scenes, and now, as she walked down the hall, she saw him smirking by the water fountain. She walked over to him, determined to ask him what he was smirking about, but instead found herself pinned against the wall, his lips over hers, his hands all but to himself.

"Gibbs!" She pulled away, warning him in a low, hushed voice.

"Don't care," he smiled again, placing another chaste kiss on her lips before taking a few steps away. "Better?"

"Hardly," she growled lowly, her eyes narrowing, but a small smile gave her away before she cupped his cheek and kissed him again.

"Oh God, you're kidding me, right?" They both turned, startled to find McGee, looking sick, and Abby, smiling, a few feet away. "You're really together now?"

"Of course they are McGee! It was only a matter of time… five years worth of time, but still it's better than nothing-"

"Abby." Ziva held up her hand, silencing her friend.

"Relax, McVirgin – I know this may seem foreign to you, but really it's quite normal." Tony teased, and Ziva gently ribbed him.

"Is there something you needed, McGee?" Ziva asked, her voice steady, but with the slightest hint of annoyance.

"We have a crime scene – Gibbs wants us there."

The three agents walked back into the bullpen, quickly gathering their things.

"Is Gibbs even here yet?" Ziva looked around before focusing on her task once again.

"Watch out, he'll catch you off guard, babe." Tony laughed, hoisting his backpack over his shoulder before receiving a hard and decisive blow to the back of his head.

"What did you just call her, DiNozzo?"

McGee smiled, "Busted."
