A/N: Thanks so much for all the reviews I've been getting! To Dixie Dewdrop: I felt as if Jenny wouldn't be Jenny if she didn't warn Tony against dating Lina and Ariele. As for the twins, well, if they were raised by a Shepard, it would be surprising if they didn't be cheeky.

To Leftmyheartinparis, fashiongirl97, KrisShannon and missmerrymak: I'm so happy you guys liked the last chapter, and I really hope you guy will like this one as well.

ENJOY!

"What is it, Jenny? Who sent this?" asked Jethro.

"I'll get to that later." She said, rummaging around her dressing table drawers, looking for something. "I have to tell you something. My sisters aren't the only siblings I have."

She opened the last drawer on her dressing table and pulled out two letters.

"I had an older brother named Aaron. He was the oldest among all of us. He worked with the CIA. My mom was a CIA Agent as well. When my dad died, there was tension between them, and that lead to a huge fight. Apparently, my mom was trying to hunt down La Grenouille. And Aaron was trying to stop her from doing anything that might jeopardize the family." She took a deep breath. "Eventually, they joined forces and they took out Rene Benoit together, but his henchmen were too strong. They took out everybody, but they succumbed to their wounds while on the way to the hospital. They both instructed someone to write down the words on the way to the hospital."

She wiped away a tear that slipped down her cheek. He wrapped his arms around, giving her the comfort she needed.

"The day of their funerals, the lawyer said that Aaron and mom had each written a letter for me." She handed him a letter that looked like it had been handled a lot. "That one is from my brother."

He carefully unfolded the letter and started to read.

Dear Jenny,

The time will come when you, the youngest, will need to protect your sisters and family. There are dangers lying ahead of all of you. Whether it be a year, ten years or even fifty, I do not know. You only need to know one more thing: THE MISSION WASN'T COMPLETED. Mum will tell you everything you need to know.

Tell your sisters I'll miss them. Take care and be safe, Jenny. I'll miss you.

Love,

Aaron.

"Poetic," joked Gibbs. Jenny smiled.

"He was always the wise one among us all, the one that pulled us out of trouble." She said, staring into space.

"How old were you when they passed away?"

"I was twelve when my dad died. Fifteen when my mum and Aaron died." she said sadly.

"Your brother sounds like a good man." Said Jethro.

"He was one of the two best men I ever knew." She said, looking up at him. She told him with her eyes that he was the other man.

He returned the smile and kissed her softly. She handed him another letter. It looked like it had been handled often as well, but it was a bit longer than Aaron's letter.

"This is the letter my mum wrote."

Dear Jenny,

If you're reading this, it probably means I'm dead. I'm so sorry for leaving you and your sisters in the dark, but this is something I have to complete by myself.

When your father died, and the police couldn't find a shred of evidence that it was a murder, I knew straight away who did it. La Grenouille.

You see, La Grenouille was trying to convince your father to take a bribe. Your father, being your father, refused. And so, that is where I come in.

I was prepared to die, just as long as I knew that La Grenouille has been brought down. As you know, Aaron tried to stop me from being reckless and told me that I was an only parent now, and my children needed me.

As always, I ignored him. I ignored the warning signs because I needed to avenge the man I love. I'm so sorry for leaving all of you when you were all so young, honey.

But there's one more thing. Katherine Arabella Benoit. That's Rene Benoit's lover and mother of two children, Jacqueline and Jeanne Benoit. Your brother and I have eliminated Jeanne, Jacqueline and Rene, but Katherine swore revenge and escaped unscathed.

There will come a time, sweetheart, when you have to choose between saving one of your sisters and another that you love dearly. I will not tell you what to do, but I trust you will do the right thing and make the right decision, as always.

You will lose a lot before you will finally kill her, sweetheart. You may even lose your life in the process, but don't be foolish and run away. It will only come back to bite you in the ass.

Once again, I'm so sorry for not being there when you need me, sweetheart. Your father and I will be watching all of you from above, all the way. I'm praying that you won't join us anytime soon.

Give all your sisters my love, will you? Take care, sweetheart. Be brave and strong.

Love,

Mom.

He folded the letter and handed it back.

"Your mom….. she sounds a lot like you." He said, after a long pause. She smiled, her eyes starting to water.

"That's what a lot of people used to say. I never believed it until the day she died." he waited, but she didn't elaborate, so he said,

"That note…. K.A.B…. That's-"

"Katherine Arabella Benoit, yes." Finished Jenny. "Rene Benoit's lover."

"And she's the one coming after you?" he asked. Jenny nodded. "But…why you? I mean, Heather's the oldest, isn't she? Why target the youngest?"

"My mom and Aaron knew that one day- I always wanted to serve my country," she said. "I didn't have a doubt in my mind. But my sisters- they all wanted to be different things. Heather wanted to start a family of her own. Jade- she wanted to be a lawyer. Amelia was always the artsy one, and she wanted to be a fashion designer."

"They all got their dreams. And my mom didn't want to destroy that. My mom knew that I wanted to do good, protect the country. She chose me specifically because she thought, if I could protect the country, I could protect the family. So she suggested I become an NCIS Agent. She didn't want me to join the CIA because of her reputation she got after hunting down La Grenouille."

"Was it a good reputation?" asked Jethro.

"Nope. She was quite a bitch, actually." Said Jenny sadly. "She became that way after my father died."

"So there's only one thing left to do?"

"Two, actually. Need to warn my sisters and nieces first."

"They do know about this, don't they?" he asked seriously.

"They do. We've discussed this many times. If Katherine comes back, it's code red."

She smiled.

"Thank you, Jethro." She said softly.

"For what?"

"For being here. For listening." Said Jenny, kissing him softly. "No one's ever listened to me for that long before."

Jethro sighed. Jenny looked at him questioningly.

"It's just… I've only just gotten you back, Jen. What if this kills me? Or worse, you? I don't think I can lose someone else I love." He said sadly. She kissed him passionately.

She didn't answer, because she didn't know what to say.

As usual, read and review!
