Got a major surprise for Kate and Tony in this chapter…

Here we go! Chapter 15! Enjoy :-)

Not even going to say it, cause you know what it is! But in case you don't know, I DO NOT own NCIS or anything related to it!

The next morning brought a gentle calm as Tony and Kate headed back to work. No longer plagued by the worry of what would happen to Arissa, they could now focus on their own child. Today was Kate's ultrasound appointment and she and Tony were looking forward to seeing their baby again.

"Seriously Hon, you need to get maternity clothes!" said Tony as he stepped onto the elevator carrying a half asleep Arissa in his arms, followed by Kate.

"No, I don't!" snapped Kate. "My clothes fit fine!"

"You're not wearing your clothes, you're wearing mine!" said Tony noting Kate's selection of one of his Adidas sweatshirts and a pair of jeans for work.

"Your shirts are more comfortable."

"No, they're bigger!"

"I still fit in my pants."

"That's because you don't button them anymore!"

"Can you tell?" asked Kate, examining her outfit.

"Buy some maternity clothes!"

"No! I refuse to wear those pants with the stretchy waistband! By buying those, I am admitting that I have gotten fat! Do you think I've gotten fat? Is that why you want me to buy maternity clothes?"

"That's a loaded question, Kate. But you have to admit you have put on a bit of weight in the past few weeks but that's because you're pregnant!"

The elevator dinged.

"So you do think I'm fat?" spat Kate as she walked off the elevator.

"Someone is hormonal this morning!" said Tony as he followed after her.

Abby heard Kate and Tony's arguing before they even entered her lab. "Morning guys!" said Abby as Kate and Tony walked in. "What are you arguing about this morning?"

"Tony say Kate fat!" said Arissa, rubbing her eyes as she started to wake up.

"No, I didn't! All I said was that Kate should buy some maternity clothes so she doesn't have to wear mine!" explained Tony.

"In order words, I'm getting fat!" spat Kate.

"Come on, Kate! You're creating a little life in there! You may be getting bigger but it's for a good cause!" said Abby, gently patting Kate stomach.

"So you're calling me fat too?" asked Kate.

"Wow! Someone is a little moody this morning!" said Abby, in shock of Kate's short temper.

"Tell me about it," whispered Tony to Abby.

"Sorry!" groaned Kate as she sat down on Abby's stool. "It's just pregnancy sucks!"

"No, it doesn't!" said Abby as she wrapped her arm around Kate.

"How would you know? Are you pregnant?" spit Kate as she massaged her lower back.

Abby leaned toward Tony. "Definitely hormonal!"

"Told you!" responded Tony. "I think the back pain she's been dealing with is starting to make her grumpy."

"That and your insensitivity!" replied Kate, annoyed.

"Lower back pain is common during pregnancy," interjected Abby.

"Is gaining fifteen pounds in eighteen weeks?" asked Kate in minor discomfort.

"You've only gained fifteen?"

"What is that supposed to mean?"

"I'm just saying you're pretty big to barely be five months?"

"Well, you have to remember this is Tony's child I'm carrying. Its giant head is probably where most of this weight is coming from."

"Oh, that right?" said Abby as she rubbed Tony's head.

Tony laughed. "We'll see who will be laughing when you have to push my giant headed son out!"

"Here you go, again! It's not a boy!" spat Kate.

"Yes, it is, Kate! And after today's appointment we will know for sure."

"Oh, you guys are going to find out the sex of the baby today?" asked Abby.

"Yeah," answered Tony with a smile.

"No, we're not!" objected Kate.

"We're not?"

"Finding out the sex of your baby is one of the only real surprises in life, why ruin it?"

"Because how else will we know what color to paint the room? Or whether or not Anthony DiNozzo, the third, is a good fit?"

"We are not naming this kid after you!"

"We aren't naming it after me! We are naming it after my dad! I just so happen to have the same name!"

Kate rolled her eyes. "We're not finding out the sex! We'll paint the room a gender neutral color and come up with names for both a boy and a girl that we like."

"Come on, Kate! You know I have the patience of a child! I don't know if I can wait five more months to find out it's a boy!"

"You have the mind of a child too, Tony!"

"When I have kids, I'm waiting to find out the sex until they're born," said Abby. "And I'm not even considering names until I see it!"

"Been thinking about babies lately, Abby?" inquired Tony.

"Wouldn't you like to know, Tony?" smirked Abby.

"Abby, having a baby?" asked Arissa, fully awake and aware of the conversation around her.

"Oh no! I'm not having a baby!" exclaimed Abby as she took Arissa from Tony's arms.

Kate laughed. "We have a conference in MTAC in ten minutes, you don't mind watching her do you?"

"Not at all! I'm running some samples today and I could use the extra help!"

"You be good for Abby, Arissa."

"Okay," said the little girl as Kate and Tony left the lab.

That afternoon, Tony, Kate and Arissa sat inside of the waiting room of Kate's OBGYN.

"Nozzo, when are we going to see the baby?" asked Arissa, impatiently.

"In a few minutes," said Tony, trying to calm the little girl's nerves.

"Is its heart going to go fast again?"

"Yep!"

A nurse walked into the waiting area. "Caitlin Todd?"

"Right here!" said Kate as she, Tony and Arissa got up and followed the nurse back to the examining room.

Inside the room, Kate sat on the examining table while Tony held Arissa in his lap in a chair next to Kate.

"Are you sure, you don't want to know if it's a boy or a girl?" asked Tony.

"Yes, Tony. I'm sure," replied Kate.

"Could I at least know?"

"No, Tony! I want it to be a surprise for the both of us!"

"But Arissa wants to know."

"Want to know what?" asked Arissa.

"Don't you want to know if Kate is having a baby boy or a baby girl?" asked Tony.

"No, I want it to be a surprise!"

"Kate told you to say that didn't she?"

"Yeah."

Tony rolled his eyes. "Fine, if you want to wait. We will wait!"

The doctor walked in.

"Ms. Todd, good to see you again!" said the doctor as he closed the door behind him.

"Hello, Dr. Miller. You remember Tony and Arissa."

"Yes, I do. How are you?" said Dr. Miller.

"Good," replied Tony.

"We see the baby today?" asked Arissa in excitement.

"We sure are! Kate is eighteen weeks so depending on the baby's position we will be able to see it's genitals and tell if it's a boy or a girl," explained the doctor.

"What's genitals?" asked Arissa.

Tony looked at Kate. "Um, it's special parts that people have that make them boys or girls."

"Nice save," said Dr. Miller, impressed by Tony's explanation. "Before we get to the baby, how has mommy been?"

"My back has been bothering me lately," explained Kate.

"Back pain is normal. It's just the effect of gravity on your growing uterus."

"Should I leave?" asked Tony. "You guys are talking about uteruses?"

"Wait, until we start talking about my cervix!" joked Kate.

The doctor laughed at the couples banter. "How has the nausea been, Kate?"

"Still get it from time to time. Not as bad as before."

"That's good! Have you felt any movement yet?"

"Not yet!"

"Well, give it some time. You will be feeling this little one moving around in there soon enough."

"What about snoring, Doc?" interjected Tony.

"What about it?"

"Well Kate doesn't usually snore but lately, I've been tempered to lay her out by the ports so she can guide in ships with the sounds she makes in her sleep!"

"Tony!" exclaimed Kate.

Dr. Miller laughed. "The hormonal change is probably causing her some stuffiness not to mention the added weight. Try using a humidifier or sleeping with some extra pillows under your head."

"On it," said Tony as Kate rolled her eyes at him.

"Speaking of weight, eighteen pounds in the first four months? Enjoying those pregnancy cravings are we?" said the doctor looking at Kate's chart.

"No, not at all. I haven't had any craving and my appetite hasn't changed that much."

"If eating two McDoubles can be considered normal?" interjected Tony.

"While eighteen pounds is more than usually, it's nothing out of the ordinary. So, shall we take a look at this little one?" asked the doctor as he helped Kate lay back on the table, lifting her shirt to reveal her rounding belly.

"Kate tummy big!" said Arissa, point at Kate's belly.

"It sure is. That's because she has a baby in there," said the doctor as he squeezed gel onto Kate's stomach.

He ran the wand over Kate's stomach, looking at the ultrasound screen. The doctored turned on the volume allowing Tony, Kate and Arissa to hear the rapid thumping of the baby's heart.

"Here we go! Nice strong heartbeat!"

"Can I see?" asked Arissa, leaning out of Tony's arms trying to see the screen.

The doctor turned the screen revealing the black and white silhouette of the unborn child.

"Everything looks good so far. Are you two interested in finding out the sex today?"

Tony sighed. "Kate here wants us to wait."

"More excitement for the delivery room," said the doctor as he continued to look at the screen.

"What that?" asked Arissa pointing to a large circle on the screen.

"That's the baby's head!"

"What that?" asked Arissa pointing to another area on the screen.

The look on the doctor's face changed as he turned the screen around to get a closer look at the screen.

"Is there something wrong, Doctor?" asked Tony as he saw the look on the doctor's face.

The doctor continued to roll the wand around Kate's stomach.

"Is everything okay?" asked Kate with worry in her voice.

"I think so…" said the doctor as he stared at the screen attentively. "We did an ultrasound prior to this one, am I right, Kate?"

"Yeah. Two weeks ago. You said everything was fine."

"What's going on, Doc?" exclaimed Tony, unable to contain his emotions.

Dr. Miller raised his eyebrows.

Kate and Tony sat at their desks silent while Arissa played with her teddy bears on the floor.

"You okay, Kate?"

"I'm fine, Tony."

"You want to talk about it?"

"There's nothing to talk about."

Gibbs entered into the Bullpen.

"Hey, how did the appointment go?"

Tony and Kate said nothing.

"Let me guess, it's a boy?" said Gibbs, noting the look on Kate's face.

"We decided not to find out the sex just yet," answered Tony.

Gibbs looked at his two agents. "Then what's wrong? Everything okay with the baby?"

Tony let out a heavy sigh and he ran his fingers through his hair. "Everything is fine. Per say."

"Per say?"

"It's just…"

"It's just what, DiNozzo? Spit it out?"

Tony picked up the ultrasound photo and handed it to Gibbs. "Dr. Miller said because of the position of the baby during the last ultrasound they probably weren't able to detect it."

"What exactly am I looking at, Tony?" asked Gibbs as he examined the ultrasound photo.

Abby and McGee walked into the Bullpen. Abby rushed over to Kate, beaming with excitement.

"How did it go?" exclaimed Abby, eager to hear about Kate and Tony's appointment. Her excitement quickly disappeared when she saw the distressed look in Kate's eyes. "What's wrong?"

Gibbs handed the ultrasound photo to Abby who examined the picture carefully. "What's this?" asked Abby, concerned.

"Abby! Abby! Guess what?" shouted Arissa as she got up off the floor and ran over to Abby. "I got to see Kate's babies today!"

"That's nice, Rissa but I really need to talk to Kate…" Abby paused as she replayed Arissa's words in her head. "Wait, babies?" Abby looked at the picture again. "There are two!" exclaimed Abby.

McGee took the photo from Abby. "Oh my god, there are!"

"We're having twins," sighed Kate.

I'm going to be an aunt twice!" said Abby as she hugged Kate.

"Wait, you two know you were having twins all this time?" asked McGee.

"No, they just found the other one. Apparently, it was shadowed by the other baby during the first ultrasound, which is why they didn't detect it. They call it a hidden twin."

Abby smiled. "I knew there was a reason you were getting so big!"

"You wanted this to happen, didn't you?" questioned Kate.

"No! But I thought it would be cool if you and Tony had twins! Two little boys, or two little girls or one of each!" exclaimed Abby. "Are they sure it's only two? What if its triplets? Triple the ToNozzo!"

"They checked, it's only two," said Tony

"Thank God!" exclaimed Kate.

Gibbs looked at Tony and Kate in disbelief. "You're having twins? I thought it was something serious?"

"This is serious, Gibbs! Yesterday, we take custody of Arissa, today we find out I'm pregnant with twins! In a matter of twenty-four hours I have acquired three kids! Four if you include Tony!" spat Kate.

"Kate, isn't taking the news it to well." whispered Tony to the senior field agent

"Clearly!" said Gibbs as he looked to the female agent.

"Sorry, I'm just feeling a bit overwhelmed, right now!" replied Kate.

"If I had to deal with two of Tony's kids I would feel overwhelmed too!" joked McGee.

"Shut it, Probie!"

"This is a lucky week! First you guys get Arissa not you're having twins! You should play the lottery!" exclaimed Abby still excited about the news.

"Yeah, I feel real lucky. Not only does Tony get me pregnant, he gets me pregnant with twins!" replied Kate.

"It wasn't like I was trying, Kate!" objected Tony.

Kate shot Tony an evil look.

"Well, I say we celebrate! Who's up for dinner at my place?" asked Abby.

"Sounds great!" exclaimed McGee.

"I'm game! How about you, Kate?" asked Tony.

"Sure, why not," replied Kate, emotionless.

"There isn't much going on here, why don't you all go home early today?" suggested Gibbs.

"Seriously, Boss?" questioned McGee, shocked at his Boss' suggestion.

"Yeah, have fun! Enjoy your weekend!"

Everyone dispersed, gathering their thing to leave.

Gibbs approached Kate. "You okay?"

"Yeah, I'm fine," said Kate unable to look Gibbs in the eyes.

"You know, the thought of having kids is just as surreal for women as it is for men. The idea of having one kid is one thing but two?"

"I've never been so unsure in my life, Gibbs. I have all the confidence in the world as an agent but as a mother?"

Gibbs pulled Kate into his arm resting her head on his shoulder. He gently kissed the top of her head. "You'll be fine, Kate."

"How can you be so sure?" asked Kate as she wiped tears from her eyes.

Arissa ran up to Kate.

"Kate, Kate! We going to Abby house for dinner?"

"We sure are!"

"Yay!" said Arissa as she hugged Kate's leg.

Gibbs looked at Kate. "I just know!"

Did you see that coming? As always reviews/comments are welcomed and an update is coming soon :-)
