A/N: I literally found this draft on my computer from months ago. I don't know how interested you'll be due to it being about Densi going undercover as a married, but I did write this before we even knew about the married episode... So, give it a go, yeah? :)

Plus it's completely different from what we've heard about the May 8th episode :)

So I split it into a bunch of different parts, and I'm going to upload it. (Obviously)

I totally forgot about this, I remember when I started this, I did so much researching into the La area 0.0 and guns and cars, so yeah the addresses are real in this... you can literally find them on Google maps.

The start about Hiroshima and Nagasaki is surprisingly the only thing I didn't research (I'm very interested in History and took it at school), So yeah, I really hope you enjoyed this, and I'm forcing Beth into proof reading – Yay :D

Deep Cover.

Henrietta Lange was once again sending her agents out of the mission, but this time not for a simple day job. This one would take longer than two minutes planning, and Henrietta Lange had spent three weeks on choosing the best attack for this certain job.

What was this job? An A-BOMB had been stolen from Malibu defence office. One in a long line of many new prototypes, physically formed and made identical to the one that hit Hiroshima and Nagasaki – but this one was way more technologically advanced, and has been rumoured to do 4x the damage of the one dropped by Enola Gay in 1945.

But this was a prototype, unsteady and unsafe for transport or any means of removal/retrieval – so how had they done it? Only a select handful of the US government knew about this bombs existence, so it had to be somebody on the inside. The mission was to get to it and shut it down.

The A-BOMB had been tracked to an arms dealer working out of a warehouse lot in Stockton – very close to the San Francisco Naval communication office.

But this wasn't going to be as easy as storming the place with S.W.A.T, doing that could risk losing lives of many and put pressure on the subjects so that they could set the bomb off right there. Their mission, the OSP, was to infiltrate the dealers ring and successfully obtain the location information about the section of the ring that took the bomb and what they planned to do with it; only then would an accurate risk-free operation by the FBI, LAPD, SFPD and whatever other attention seeking agency be planned and followed through.

But as for now, the pressure was being put on the NCIS: Office of Special Projects undercover team to retrieve the information needed and get the country out of the woods – more importantly to keep this from causing mass-panic and reaching the media. So here she was, Henrietta Lange, ready to tell the team of their new mission.

Eric Beale and Nell Jones had been briefed on this days earlier, and since then had been erasing the lives of G. Callen (not that there was much to erase), Sam Hanna, Kensi Blye and Marty Deeks as under the radar as possible. And were currently in the process of creating new identity's and backstopping everyone on the team – right down to their first words.

"It's good to see you all here," Hetty entered the bullpen, hands clasped in front of her.

"Yeah," Callen paused. "Why wouldn't we be here?"

"There is a new job," Hetty paused and looked up "It requires you to go deep undercover for a very long time."

"What?" Kensi started paying more attention her, and less to subtly flicking paper at Deeks.

"An atomic bomb has been stolen from Malibu's defence office, and they need us, you, to go undercover and infiltrate the arms ring to retrieve information on the whereabouts of the bomb, but that is not going to come easy... You will need to take up new identities, and infiltrate it the hardest way ever – on your own merits."

"And we've only just been asked? This is going to take weeks of preparation." Callen stood up.

Hetty took a few steps closer to him. "I was informed three weeks ago, and I have been going over best plan of attack. I briefed Mr Beale and Miss Jones of the situation two days ago, since then they have been erasing your whole life and are almost finished fabricating and perfecting your new one."

"So, what are our cover stories?" Kensi focused Hetty's attention away from Callen.

"They are not cover stories, Ms Blye, they are your life, your identities." Hetty paused. "And if you go upstairs, Mr Beale and Miss Jones will give them to you, your driver's licence, credit and debit cards, insurance, social security numbers, passports, even your new birth certificates, everything is ready."

"Okay, let's go get them then," Callen said slowly as they all stood up and made their way to the stairs.

They all walked up to the doors as they opened on cue, Nell and Eric at the ready with their iPads, four drivers licenses with their pictures name up on the screen.

"Explain," Sam pointed at the screen.

"Okay so we have created your new identities, right down to your first hiccups. Everything is here, credit reports, taxes, payments," Eric began

"Callen, your new name is Michael Tunney, 38," Nell said. "You are single; you drift form job to job and live in an apartment on El Dorado St. You have a shady background and a colourful criminal record, breaking and entering, auto theft, possession of illegal substances and you stabbed a man on the street in 2000."

"Why is that necessary?"

"The arms dealer isn't stupid enough to hire somebody with a clean slate." Nell paused. "So you basically all have some dark past"

"Sam, you are 42, an ex-marine who was dishonourably discharged for an unexplained shooting connected to you in 1998, you had a 2 year stint in Colorado maximum security for aggravated assault in 2005-2007," Eric told him. "Your name is Dmitri Sazbo, also single living in the same apartment as Tunney, that's how you meet."

"Kensi, Deeks, your new identities are married," Nell said.

Kensi choked on her water "What!"

Deeks smirked.

"Your new identities are Warren Lisbon, 31 and Cailin Lisbon 29 – trained killers." Nell mimicked Deeks' smirk "You met when you were hired to kill each other in 2003, Deeks, you have killed 12 people, and your weapon of choice is a modified glock 19 airsoft with a custom silencer."

"Nice." He was used to glocks and couldn't wait to try this one on for size.

"And Kensi, you have killed 7 people, and your weapon of choice is a US Army knife and a simple Beretta 92fs." Nell paused again. "You have a four year old son called Lucas, born early in 2009 and he is why you managed to quit the business of killing. You are now a Gym teacher at elementary school – that's your day job, and Deeks, you are a lawyer; but you both want to get back into your true passion now your son is in school - guns for hire."

Kensi choked again on her water and this time decided to put her bottle down. "How are we going to fake a child?"

"That's where he comes in." Hetty walked in holding a four year old boys hand, he had light blonde hair and was smiling. "Meet Louis Kendall, a.k.a Lucas Lisbon."

Kensi look at Deeks then back to Hetty. "Is it wise to bring a child as young as four into this – giving him to us?"

"Yeah I agree with Kens'." Then it hit Deeks. "What about his parents, you said this could be a long mission."

"He is an orphan, was an orphan. And we believe you can hold your cover, plus you will have help, your home is 1012 South Lincoln Street – Lucas will attend kindergarten at Hazelton School, just across the road from your home," Nell said, pulling up a picture of their new home on Google Maps.

"How do we meet Sam and Callen?" Deeks asked, trying to avert his eyes from the child whose life will be in his and Kensi's hands.

"You will meet them in the trade, you two decided to go back into the job when your son goes to school. You will try to be hired by one Richard Hanson, one of LA's most wanted arms dealer – and who seems to be the number one suspect in the 'who took the bomb' fiasco. Even if he hasn't inserted it into one of his rings, sources say he definitely has it in his possession. An L.A.P.D source was put on high alert and spotted blueprints and movement records floating around his 'territory'," Hetty told them as she handed out big brown envelopes to them all.

"Our identities." Kensi sighed at the envelope, taking out her wallet and placing it on the light table. "Don't lose that."

Everyone did the same, surrendering their wallets, badges and guns to the light table. Hetty handed Kensi another, smaller envelope. "This is Louis, Lucas' birth certificate and the money to pay for his Kindergarten tuition and the nanny's fee for the next 2 months. Mr Deeks, Mr Callen and Mr Hanna, the keys to your home are in your envelope, each of your homes are furnished, and Ms Blye, there is another set of keys in your bedside table. As are your coms – everyone, only wear them when you need to contact us, and only when it's urgent. They have new people working for them, and high tech systems that can sense and track outgoing and incoming transmissions."

"Mommy," Louis – Lucas – the four year old said, breaking the silence of everyone searching through their envelopes.

"I believe he is talking to you Ms Blye," Hetty smiled, letting go of the boys' hand, letting him toddle over to Kensi.

"What... How? He hasn't even met me," she said confused. Callen and Sam smirked at her confusion.

"His carers have been teaching him for two weeks who his new Mommy and Daddy are," Nell smiled.

Deeks just stared at her as she bent down to the child's level, putting her hands under his arms and lifting him. "Hey," she smiled at him; she was scared shitless of holding him, she was afraid of dropping him.

"Hey Mommy." He cuddled into her shoulder.

Kensi froze slightly, sensing how safe the boy felt in her arms.

"We need to go pack, when are we leaving?" Callen said in an attempt to take focus off of Kensi and the boy – he succeeded with everybody but Deeks who was still staring, astounded at Kensi's attitude towards the child.

"You will be leaving later this afternoon, so go pack, Ms Blye, Mr Deeks, go together, stop at each other's houses, try to get Lucas to see you together as his parents. This is vital he sees you bond with him and each other."

"My place first," Deeks said – as his was closer.

Everyone left the mission, Deeks was immediately surprised when he got to Kensi's car and saw a child seat had been installed. "That woman thought of everything..."

"Uh-huh, apart from the fact neither of us are set or have had any type of experience with living with a small child," Kensi said, opening the door with one hand and lifting Lucas up.

"We're equipped enough to handle this, plus, he already likes you." He motioned to the boy sitting calmly in the seat, in his own little world.

"Good luck to us," Kensi said, struggling with how to clip the boy in.

"Having some trouble there?" he asked as he came up beside her.

"Yeah," she admitted, moving out of his way letting him try.

"You do it like this," he demonstrated.

"How do you even know that?" she asked.

"I help out at more than the homeless shelter," he smiled.

Kensi ran her fingers through her hair. "Why did Hetty choose us to have a kid...? I can't even clip him safely into his seat."

"Because she couldn't put the kid with Sam and Callen. They needed to be lone-wolfs, and they couldn't put Sam or Callen with you – it would take ages to 'get to know each other'. She probably learnt from the reports of Hunters partner switch up that we're no good with anybody but each other," Deeks said. "I don't quite know why a child was needed though; it puts us and him in more danger because we have to protect him, and nothing will be secret in the ring, we will have to face the chances of them threatening to screw with our family."

"God what's was running through her head," Kensi said, double checking the boys straps. She closed the back left passenger door, walking around the car to the passenger side – letting Deeks drive so she could keep an eye on Louis – Lucas.

"Family image?" Deeks asked as he put the car into drive. "We needed an excuse as to why we fell off the planet five years ago - Cailin - you having a baby gave us that reason."

"Five years?" Kensi paused. "Oh, the pregnancy as well." She chuckled slightly at her slight idiocy.

Deeks adjusted the mirror so he could see Lucas/Louis, smiling at the boy who was messing with a toy Hetty must have given to him.

"How are people even going to believe he is my son? He bears NO resemblance to me," Kensi frowned.

"If you say it's your child, people will think it's your child, therefore, they will see a resemblance you don't see, one that's not there," Deeks smiled as they drove in the direction of his house.

A/N: So I really hope you enjoyed that – and my usual review rule is in place – if it's shit don't review, if you like it, tell me in reviews so I know if I should carry on or not :)
