Here's kind of an intro for the story.

38 Leroy Jethro Gibbs 'Gibbs or Jethro' - Was married three times and has a son from each marriage. He has worked at N.C.I.S. for 18 years.

30 Jennifer Shepard 'Jenny or Jen' - Has been married twice. Two girls from her first marriage Another from a different and very short marriage. Just started working at N.C.I.S. After her last marriage she went back to her maiden name.

9 Anthony Devin Gibbs 'Tony' - Likes sports, cars, and driving his brothers crazy.

7 Timothy Jet Gibbs 'Tim or Timmy' - Computer geek and book-worm.

5 Jimmy Jack Gibbs - The youngest brother who is also a fan of books. He also enjoys time with his uncle Ducky who taught him how to read.

8 Caitlin Rachael Shepard 'Kate or Katie' - The oldest of her sisters makes her very protective. She is known to beat up anybody who makes fun of her sister. Even punched her step-father once for yelling at her mother.

6 Abigail Grace Shepard 'Abby or Abs' - Has a unique style with spikes and metal boots. She also has a love for science.

3 Ziva Jasmine Shepard - She being the youngest doesn't mean she can't pick a fight or two like Kate. One time gave a boy at the park a black eye for throwing sand at the little kids.

4 Lilly Kristie Brown - Even though she's younger than them she becomes best friends with Timmy and Abby. She likes computer stuff like Timmy and takes a liking to science after meeting Abby.

It's a little AU, but I think every story that has the team as kids is going to be AU. And I don't own NCIS.

It was Jenny's first day at work and she ended up dragging her three children with her. Gibbs was the first to notice her walk in.

"You must be the new agent, I'm Agent Gibbs."

Jenny smiled and shook his hand.

"I'm Agent Jenny Shepard. I am so sorry that I had to drag my kids with me."

Gibbs shook his head.

"It's fine. My three are here too."

Jenny smiled. While Gibbs showed her where her desk was.

"Your welcome to send them to Ducky the M.E. or the forensic scientist, Lana Brown."

Abby started jumping up and down.

"Lana! Science!"

Gibbs laughed.

"Come on we'll go down to the lab first."

When they walked into the lab a girl dressed completely in red minus her lab coat turned around.

"Lana do you think you can handle an extra child?"

Lana looked at the group.

"Sure I can handle an extra one, Timmy and Lilly are easy kids."

Jenny spoke next.

"I'm Agent Shepard and my daughter Abby who loves science."

Lana bent down to Abby's level.

"Good because all Lilly and Timmy do is play on my computer."

After the group left Abby with Lana they went down to autopsy.

"Jethro who do you have with you today?"

Jenny beat him to it.

"I'm Agent Shepard, this is Caitlin and Ziva."

"Nice to meet you Mrs. Shepard, Caitlin, and Ziva."

Jenny smiled at the older man.

"You are welcome to call me Jenny."

"Well then you must call me Ducky."

Just like that a little boy wearing scrubs like Ducky walked out.

"Uncle Ducky can we finish the story now?"

Gibbs motioned for Jimmy to come towards him.

"Jenny this is my youngest son Jimmy."

Jenny gave the little boy a smile.

"Are Timmy and Lilly your's also?"

Jenny had caught a quick glance at two kids sitting around a computer in the lab. Gibbs chuckled.

"Timmy is mine, but Lilly is Lana's little pop-tart. My oldest son is around here somewhere."

Nobody noticed a boy sneaking up behind Kate. As soon as he screamed boo he was screaming in pain. Kate had him pinned to the ground.

"Katie get off him now and apologize."

Kate got off him and crossed her arms.

"Sorry"

Ziva was laughing at him. Gibbs walked up to Tony and gently hit him on the back of the head.

"This would be my troublemaker Tony."

Jenny raised an eyebrow then shook her head.

"Your troublemaker, I have three always giving me trouble. Especially these two."

Gibbs noticed Jenny look at Kate when she said this. Kate also noticed her mother's gaze.

"What that ungrateful, stupid, and evil man deserved it?"

Now it was Gibbs' turn to raise an eyebrow.

"Ungrateful, stupid, and evil man?"

Jenny bit her lip.

"She's referring to my ex, Eli David."

Gibbs' eyes got big and he spit his coffee all over the floor.

"You were married to the director of Mossad."

Jenny covered Ziva's ears.

"Yes, and don't mention Mossad around my children especially Ziva."

Jenny than removed her hands. Gibbs looked at her than turned to Ducky.

"Can you watch Ziva and Katie while we work?"

Ducky looked at the three kids.

"I'll try my best."

Jenny bent down to look her daughters in the eyes.

"Behave for Ducky or else no training this weekend."

Gibbs and Jenny walked out of autopsy. Gibbs turned to Jenny.

"Training?"

Jenny shrugged.

"Like you pointed out I was married to the director of Mossad. I need to know that if my kids ever needed to they could protect themselves. It's simple training but they enjoy it."

Gibbs decided he needed to start teaching Jenny the rules.

"Rule number nine always carry a knife."

Jenny smiled and moved her jacket and pulled out a knife.

"Ziva and I follow that one already."

Gibbs looked a little stunned.

"She's what four and you let her have a knife."

Jenny acted like it was no big deal.

"She's three and comparing to the fact she's Eli's daughter I think that's safer then a gun. She knows how to use the knife and to only use it in danger."

Gibbs shook his head. This woman was going to causing lots of head aches.

I'm aware that Jenny and Gibbs are a little OOC. But in the story Jenny was married to Eli so it's going to make her prospective on the situation a little different.
