B/N: Gibbs has come to term with the idea of Kate and Ari because she told Gibbs she was falling in love with Ari a few months before. It's the team that has issues and they soon find Kate has gained some new skills.

The morning of the twenty-second Gibbs sat at his desk going over paperwork, it was the usual things like field reports and case reports when he found a report from the HR department. He opened it and found it was a noticed of change of name for one of his agents...Kate. It pissed him off that she'd married the bastard.

To Whom It May Concern,

Special Agent Caitlin Todd has filed a change of name form that coincides with the notice of marriage. This is to inform all senior agents that her name has legally changed. From this moment forward the agent's name is not Caitlin Rebecca Todd but Caitlin Rebecca Haswari.

NCIS Human Resource Department.

Gibbs stared at the paper in both surprise and frustration, by this time McGee and Tony arrived.

"Have either of you spoken to Kate?" He looked at them, Abby and Ducky came in the room, "any of you...have you spoken to Kate?"

Abby smiled, "I talk to her last night, she called me from her apartment to say she'd be coming back to work today. She said she's be bring Ari with her."

He stood and grabbed his coffee cup, "I'll be back."

"So Kate faced Mossad and lived?" Tony looked at Abby and she nodded, "wow, she must have done really good."

"I heard that Mossad is one of the most deadly organizations in the world. They have this department called Kidon that work solely on assassinations...maybe Ari was part of that department."

"That would be correct if he was working as a double agent," Ducky looked at them. "He was skilled in killing and infiltration...has me thinking he was Hamas when actually he was Mossad. Kate had me getting Gerald to talk about Ari's time in autopsy...everything that was good and bad...I'm quite surprised Gerald agreed but only after I told him that Kate was turning Ari around."

"Gibbs had us writing reports as well, do you think Kate asked us to. Did our accounts save Ari because that would be odd."

McGee nodded, "Kate was secret service so she knows how to talk with people who have an air of authority."

Ducky smiled as the elevator dinged, Kate got off with Ari. "Here's our Agent Todd now."

Kate smiled at them and was offered hugs, she spoke upon hugging Ducky. "it's good to see you all, I honestly didn't think I'd leave Israel alive."

"Hold on a moment." Tony looked at her, "you actually saved that bastard." He pointed at Ari, "you saved him...why?"

"Because I felt I had to."

"That doesn't make it any better." Tony eyed Ari, "he's Mossad...he's the enemy."

Ari stepped forward and Kate held up her hand, "it's not worth it, remember what Mofaz said...it's not worth the fight." She smiled, "besides, if Ziva found out you got in a fight she'd just come over and put you in your place."

"It is best she do not know, for all our sakes." Kate laughed and shook her head, she motioned to the back desk.

"I'll see about removing the wall later, go sit down while I clean out my desk. We need to wait for Gibbs to come back."

Ari caught and squeezed Kate's hand before moving to the back desk. The team sat asking Kate questions and she answered them or Ari did. Her marriage never arose though nor did the team notice her wedding band. Gibbs came in thirty minutes later and Kate stood, he stared at her.

"Agent Haswari."

"Agent Gibbs." He looked at her and she smiled, "you said rule 12 was never date a co-worker, you never said anything about marrying one."

"You always find loopholes...why?"

Kate chuckled and moved around the desk to Gibbs, hugging him. "It's good to see you too Boss, he's back there waiting on his entry to the team."

Tony and everyone stared, "hold on, you married the bastard?"

"And took his name, my name is Caitlin Haswari not Todd any longer. We got married on the twelfth of this month."

"You have got to be kidding me," Abby stood and folded her arms. "Why, after all he did to you?"

"I love him, it's as simple as that. Listen, just hold off on the comments and everything will be fine."

Everyone soon dispersed and Gibbs took Ari to the elevator and spoke to him. Tony eyed her as the doors closed. "He'll be dead when those doors open."

"No he won't, Gibbs won't risk alienating me by murdering my husband."

Within fifteen minutes they were preparing to leave for their crime scene at the Smithsonian. A civil war mystery. The comments about Ari and Kate were placed aside, Gibbs found it was quite strange how the two acted as if they were nothing more then co-workers the entire time.

Between the forensic anthropologist and everything in between, Gibbs found Ari was able to quickly adapt to everything and working. He even managed to keep up with Gibbs while running after a suspect.

They went after Kate and Ducky to find Kate at a stand off with the anthropologist. They stayed away and out of sight while watching the scene. "Place your weapon down or I shoot the good doctor." She held Ducky by the neck.

"Alright." Kate put her gun down and the woman pushed Ducky away, Kate took the time to get her knife out and within seconds it flew into the woman's chest...killing her instantly. She moved to the men and eyed them. "Get down, now."

"We're going." They got down on the ground and placed their hands on their head.

"Gibbs, Tony, Ari, McGee you can come out from hiding now." She looked up as they came up the hill. "You were leaving me to do all the work...why?"

"Well you had it under control." Tony looked at her, "where'd you learn to throw a knife like that?"

"The heir to Mossad, who happens to be Ari's sister." She looked at Gibbs as he handcuffed the bastards she was pointing her gun at. "Next time don't wait around."

"So you trained with a Mossad agent."

Kate chuckled and smiled, "I married into Mossad...it's a long story. As far as the other officers know, I'm just the Untouchable Mossad Princess...untouchable as Ari would murder any one of them who tries to touch me. The real Mossad Princess is the heir, Ari's sister Ziva." She pulled up one of the guys. "So yes, I trained with Mossad."

"Great, I have two Mossad agents." Gibbs looked at her and she smiled. "You learned so you could know their tactics."

"Yes I did, learn what you can in the moment, it'll help one day."

"Good girl, just keep him in line and we won't have a problem."

Kate smiled and looked at Ari as McGee took the man she had. "See, Ziva was right...it does come in handy."

"You are turning into a Mossad Princess and it frightens me Caitlin...your compassion is too much for that world."

"I have you to stop if I start getting too far into that world...to save and keep me safe as you did before."

He nodded and pulled her hand to his mouth, kissing it. "I will stop you Caitlin, you should never have blood your hands."

A/N: I've decided on a girl however her name has yet to be decided, also the team won't know about the pregnancy till after the 'undercover' scene when Ari let's it slip.
