Ziva had been on edge all day; Tony had understandably been worried about her. Which is why he was now on his way down to Labby, as it's affectionately known.

As soon as Abby heard the ding of the elevator, she was on her feet, scuttling towards the entrance to her lab. When she saw it was Tony she jumped at him straight away and flung her arms around him.
"Toooooooonyyyyyyyy!" She cheered. "What are you doing here?" She questioned whilst releasing her. "Do we have a new case? Yay! That means more evidence for me! I love getting evidence… It's like Christmas all over again! You know the best bit about getting all the-"

"Abs..." He interrupted. "No new case, sorry. I actually came down to talk to you about Ziva…" After receiving a questioning glance from Abby, he elaborated. "She's been acting jittery today, don't you think?"

"I haven't really seen her today but I mean, when she was here for a bit earlier it was like she kept zoning out... She wasn't really listening." Abby pondered.

"YES! Exactly! That's what I mean. And Ziva's never like that… She's always so composed. Always has her wall up…" He started going off into his own world, wondering what was going on with her. Just then, the shrill of his phone went off.

"I thought your ringtone was Closer by Weather Star?" Abby asked.

A faint pink tint came over Tony's cheeks as her replied "Um… That's Ziva's person ringtone."

A look of understanding crossed Abby's face. "Well, that does kind of sum up your relationship perfectly" She winked. "You better answer your phone."

"Right… DiNozzo" He stated after lifting his phone to his ear. "On it, Boss! Sorry, Abs. Gotta go, duty calls." He called over his shoulder as he left the lab. Abby just looked at him with a smirk on her face.

The bullpen.

"DiNozzo. You know what's going on with her?" Gibbs demanded.

Tony just stared at him like he had two heads. "Who, Boss?" This resulted in one of Tony's beloved head slaps.

"Ziva, Tony!" He bellowed like it was the most obvious thing in the world. "She's been quiet today. It's unlike her." The concern in his voice didn't go unnoticed by Tony.

"Yeah, I've been thinking the same thing. I'll talk to her later, Boss."

"Alright, Tony. Get back to work."

"Boss." With a nod of the head in Gibbs' direction, both men headed back to their respective desks.

After this, the day went by pretty fast. There was no case and all their paperwork had been completed the previous weekend so Gibbs allowed the team to leave early. After a quick goodbye to McGee, Tony and Ziva left to go back to his apartment. The ride was eerily silent to Tony being Tony tried to lighten the mood.

"You okay?" he queried. "You don't seem like yourself today… Wanna talk about it?"

"Can we talk about this once we get inside please Tony? It is not the sort of conversation you have in the car." This didn't help Tony. His stomach was still in knots and the heavy feeling of dread swept over him. This was obviously serious or she would just come out and say it.

"Yeah sure… What movie do you want to watch anyway?" Changing the subject was best if he didn't want her to shut down before he had a chance to talk about what was upsetting her so much.

"A Christmas one maybe? One with families and a happy ending." She stated, sending him a small, genuine smile.

"Sounds perfect." He said, reaching over to give her hand a small squeeze before pulling his hand back and placing it back on the wheel.

Once they reached his apartment, he pulled two beers out of the fridge, opened them and handed one to her.

"Oh… Do you have something else? It's best if I do this with a clear head." She whispered. Tony had never heard that tone coming from her… It sounded almost scared.

"Oh, my gosh. Ziva…" He gulped and leant forward to grab her hand. "Are you dying?" He whispered. It pained him so much to have to say that and now he wished he hadn't. He didn't want to know that answer… He didn't want to hear her say yes because he couldn't handle that… But if she said no then it means something else was seriously wrong with her.

But to his surprise, she did neither. She laughed… She actually laughed. Granted it was more like an un-amused chuckle… But she was laughing. "No, Tony… I am not dying. Although, it sometimes feels like I am." Okay, this confused him even more.

"Ziva… What's going on?" He begged. He couldn't take this anymore.

"I-I'm pregnant Tony." She smiled. "It's yours, by the way."

Tony didn't move. He didn't smile, he didn't look at her. He just dropped her hands, stood up and walked out.

"Tony?" She called after him. "Tony?!"

But it was no use, he was gone.

Ziva waited almost an hour before deciding he wasn't coming back anytime soon, and so she left.

The next day at work, Tony didn't arrive and at lunch Ziva decided enough was enough. Walking into the break room, she took out her phone and dialled all too familiar number. After reaching voicemail for the 7th time, she stopped trying. She would just have to go talk to him face to face after work. Before that, she had an announcement to make to the people who actually cared about her. She text everyone to meet her in the Bullpen.

As soon as she walked in, she was faced with 6 pairs of eyes staring at her. She took turns acknowledging everyone's presence. Giving a kiss on the cheek to Ducky, Jimmy, Gibbs, McGee and Vance and giving Abby a hug that could rival her own.

"I gather you're all wondering why I called you here." Looking at the collection of nods, she continued. "I'm pregnant," She breathed. "And Tony's the father…."

After a while of shocked silence, McGee spoke up. "Is that why he got a transfer to the San Diego office?"

Ziva was speechless. Finally, she came to her senses. "He did WHAT?"
