A/N: Helloooooo! :)
First of all: Thank you so so much for your wonderful feedback for both "A NYC Christmas" and "LA Crisis"! It means a lot! I definitely appreciate all your support and love for the Alison series :) Someone told me a couple days ago that Ali was like her best friend because she never really had a best friend. And that Ali was an inspiration for her and she held a special place in her heart. It touched me deeply. I would've never thought you would actually enjoy it that much when I uploaded the first Ali story about half a year ago. It's incredible. Thank you so much!
And now: You asked for it, you got it! Here's the next story in the Alison Series :)) I really hope you enjoy it as much as the previous Ali stories. :)
Summary: When someone from Ali's past comes back into her life, how will it affect her relationship with friends, boyfriend and family? And what if that particular person is posing as her boyfriend on an undercover mission? Alison Series. Tiva.
Disclaimer: I don't own NCIS or any of it's characters...obviously. lol :D I do however own Alison and all the other characters I invented :D HA! *victory dance* :P
shout-out to Ruth for the "advice" lol :D love you, girl x3
ENJOY READING! :)

"Then call Alison for God's sake!", Gibbs ordered. Ziva's eyes widened and she exchanged a glance with Tony before speaking up: "Gibbs, she's only 16." The boss turned around and looked at her.

As he gave her the infamous stare she immediately grabbed Tony's hand for support. "Yeah, I know.", Gibbs said. "Um, boss, Ziva was just..", Tony tried but Gibbs cut him off: "DiNozzo, call Alison. Didn't we just discuss that we need a couple aged between 15 and 18?!"

Tony looked like he was about to say something else but Gibbs spoke again: "Call her! I'm gonna go call Tobias and see if he can find someone working for the FBI."

"You want someone to pose as Alison's boyfriend?", Ziva demanded. Gibbs simply nodded. "Ali won't be very happy. You know she has a boyfriend.", Tony said carefully.

"Yeah, so what?! We need someone who is trained for an undercover mission like this. Ali is trained but her boyfriend isn't so I'm gonna call the FBI. They're in this together with NCIS.", the boss declared.

He walked out of the room, leaving Tony and Ziva behind. Tony sighed and whispered: "Don't kill me, Zi. But I'm gonna call Ali now." Ziva swallowed hard but nodded. She knew that there was no way to get out of this.

Two hours later Ali was sitting in the Director's office with Gibbs, McGee, Tony and Ziva as well as Tobias Fornell, FBI Agent. "Miss David, I need you to realize how dangerous and how important this mission is.", the director said.

Ali nodded: "Yes, sir. I get it." Ali had received a call from Tony about two hours ago and he had told her that the director and Gibbs needed her for an undercover mission.

All she knew was that the mission was related to a current case that was concerning NCIS and FBI. Vance had told her that she wasn't allowed to contact her boyfriend Andrew or her best friend Ashley.

Speaking of a perfect and relaxing summer break. Alison's thoughts were interrupted when the door to the office opened and a tall, really good looking guy walked in.

He was about her age and had light brown hair. The guy was dressed in jeans, a regular t-shirt and a leather jacket. Fornell got up and walked towards the guy, shaking his hand.

He then turned around to face the group. "This is Frederick Lawrence. He's my nephew and he's going to be Alison's partner for this undercover mission.", Fornell introduced the guy.

Ali couldn't really help the grin forming on her face. It wasn't just the fact that he was quite cute but her gut feeling had been right. She knew this guy.

Slowly she got up and walked towards him, coming to a stop right in front of him. He was a little taller than she was but she managed to look straight into his eyes thanks to her high heels.

"Freddie?", she questioned, the grin now spreading across her face. His eyes lit up as he recognized her. "God, Ali! Is that really you?", he asked, grinning as well.

She nodded and he almost swept her off her feet as he hugged her close, twirling her around. She started laughing like a little girl would and as he finally put her down again she was still grinning.

"It has been years! I didn't even know your uncle was working for the FBI.", Ali declared. "And I didn't know you were living in the United States now. This is awesome. I missed you, Ali.", Freddie said.

They were completely oblivious to their surroundings. He pulled her close once again and whispered in her ear: "You could have called." Ali looked up at him and almost melted when she met his eyes.

Just when she was about to reply Tony cleared his throat bringing them back to reality. "Care to explain?", he questioned, smirking. Ali and Freddie turned around, his arm still loosely wrapped around her waist.

Usually she would have freaked at this kind of contact but it was different with Freddie. She looked straight into Ziva's eyes, expecting her aunt to recognize him but she didn't seem to be able to put the pieces together.

"Ziva, don't you remember Freddie?", Ali questioned, still grinning. Freddie chuckled: "Ali, how is she supposed to remember me? It's been years. Even longer than the last time I saw you."

Ali slapped him on the arm playfully before focusing her gaze on Ziva again. "Sweetie, I'm sorry but I have no idea.", her aunt apologized. Ali sighed but explained anyways: "Freddie and I met in kindergarten, we went to school together and everything. Don't you remember?"

Suddenly Ziva's eyes widened and she got up and walked over to Freddie and Ali. "Seriously? God, I didn't recognize you. How long has it been? Eight years?", Ziva exclaimed.

Freddie laughed and nodded: "Yeah, I guess it was about eight years. You left after your sister's death." "When did you leave Israel?", Ziva asked. "It was about four years ago.", he replied.

Ali lowered her gaze to the floor. After Freddie had left she'd been all on her own. He knew about most things that happened but they hadn't been in contact after he had to leave.

"Ali came to the US about a year ago.", Ziva declared but when she noticed her niece's reaction to the topic she quickly decided to drop it. "Well, Freddie, it's great to see you again. But I have to say I didn't know your uncle was Tobias Fornell either.", Ziva laughed.

Freddie chuckled, trying to cover up his concern for Ali. The adults didn't need to know everything. He tightened his grip on Ali, letting her know that he was there for her.

She immediately looked up and met his eyes, a smile forming on her face. "Freddie, may I introduce you to..my family?!", she eventually said. "This is Special Agent Tony DiNozzo, NCIS. He's Ziva's..fiance and my legal guardian.", she started and Freddie shook Tony's hand, smiling widely.

Ali continued with McGee: "Special Agent Tim McGee, kinda my uncle." "And this is Special Agent Leroy Jethro Gibbs, he's like a..grandpa to me.", Ali told Freddie.

She almost stumbled over the word "grandpa" and Freddie noticed this. He made a mental note to ask her about what had happened after he left later. Ali finished her talk by introducing Director Vance.

When she was done Fornell spoke up: "Alison, Frederick, we are now going to introduce you to your undercover mission." They both nodded and McGee pressed a key on the computer's keyboard.

Vance, Fornell and Gibbs showed them pictures of the suspects, explaining their backgrounds and their relation to the case. They also explained their cover story in detail. Finally Gibbs handed Ali a set of keys.

"Those are the keys to your house.", he said. Ali raised an eyebrow. "Our house?!", she questioned. "The FBI and NCIS are looking for those people because their targets usually are teenage couples whose parents are Marines. When the parents are on a mission they break into the houses and kidnap the kids. Then they blackmail the parents.", Vance explained.

"So, let me get this straight, Ali and I are gonna pose as a couple?", Freddie asked carefully. Fornell nodded: "Yes, that's correct. I think you'll manage just fine."

Ali looked up and smiled at Freddie. There were worse partners to be stuck with on a mission like this. She was actually looking forward to their time undercover.

"You are not allowed to contact anyone except NCIS or FBI. We'll have video cameras in your house but no microphones. The suspects will probably watch you as well but they can't hear what you're saying because we managed to find a special house.", Fornell went on.

"It's important that you understand this. No contact with friends or anyone.", Vance underlined the previous statement. Freddie nodded and so did Ali. As if she would contact Andrew while working undercover with another guy.

When she felt Freddie's arm still wrapped around her she suddenly knew that this was dangerous territory. But who cared? Maybe old love didn't fade away after all.

"We already got you everything you'll need. There's food in the house and we got you clothes and stuff. Your mission starts now. We got a special car for you, it's the red key. We expect you to call us tonight for the first update.", Vance said.

Ali and Freddie nodded, said their goodbyes and headed for the parking garage to get their car. This was gonna be an interesting undercover mission.
