JJ walked Tony down to the foyer and then they both went their separate ways to pick up their cars.

It was disappointing to have to split up so soon after having heard the good news, but JJ used the forty minute drive to try and sort out what she was feeling.

Sheer relief was her strongest emotion. It was over!

It wasn't as though she had doubted that it would be eventually, but they had lived with the secret for so long it had been hard to imagine what life might be like without it.

It had been wonderful to watch Tony interacting with her team. The team had become a second family to her and it had been hard to lie to them for so long. The relief that she had felt being able to tell them everything was second only to her amusement at their confused expressions when they found out that she had married 'Agent Annoying'.

Tony's car was already in the driveway when she pulled into their street and she parked her car behind his before pulling herself out of the vehicle – something that was much more difficult to do when you were eight months pregnant.

JJ let herself into the house and stepped out of her shoes. "Tony?"

"In the lounge." Tony called.

JJ made her way into the lounge and found Tony sitting on the couch, with two hot drinks on the coffee table in front of him.

"Welcome home." Tony told her, patting the couch beside him. "I've missed you."

"I missed you too." JJ slowly lowered herself onto the couch and then shifted around so that her back was leaning against Tony. "Though it sounds as though you've been busy."

Tony shifted slightly and then wrapped an arm around her, his hand ending up on her stomach. "How's Twinkle Toes doing?"

"Kicking like mad." JJ told him. "It's tiring, especially when I'm trying to work. I thought I'd be frustrated when Hotch told me I wasn't allowed to travel with the team anymore, but I'm actually relieved."

Tony's hand splayed out over her stomach and they were silent for a while as Twinkle Toes kicked at his hand.

"I can only imagine what it must feel like to feel Twinkle Toes kicking inside your body." Tony commented eventually.

"It's nice." JJ told him. "I've heard of women whose baby kicked so hard they broke ribs, but Twinkle Toes isn't that bad. Kind of annoying when I'm trying to sleep though."

Tony chuckled. "I'm sure.

"So," JJ said after a few minutes of silence. "You got him."

"Yeah." Tony's smile was audible. "We got him and it's over. Secretary Moore told me last night and then…"

"You knew last night?" JJ interrupted. "And you didn't tell me?"

"It was late," Tony explained. "I didn't want to wake you."

"You know New Mexico is two hours behind Washington, right?" JJ asked.

"I forgot." Tony said shifting slightly. "I only remembered this morning, but by then I'd decided I wanted it to be a surprise."

JJ considered that. "It was a pretty great surprise."

"I know." Tony kissed the top of her head.

"So tell me all about it." JJ told him. "What happened?"

"Well, you remember those recordings I got from Davenport earlier this week?" Tony asked.

JJ nodded.

"There were some incriminating conversation on them." Tony continued. "The conversations led us to a body which, in turn, led us to a marine who is part of Operation Frankenstein. Director Vance, Secretary Moore, and the Associate Attorney General all agreed that we had what we needed and so we arrested him."

"So did you end up telling Director Vance?" JJ asked curiously.

"Yes." Tony answered. "We needed his cooperation to investigate the body. He took it very well actually, much better than I thought he would."

"And Gibbs?"

"He pushed his way into Davenport's arrest." Tony sighed. "Davenport broke my cover on our way back to NCIS and Gibbs didn't take it so well. He insisted that I come into NCIS to explain myself to the team."

JJ winced, she'd seen Gibbs in bad mood and it wasn't pleasant. She could only imagine how angry he would have been on hearing that Tony had been lying to him.

"Will you?" She asked. "You don't have to, right?"

"I went this morning." Tony answered. "I didn't have to, but Gibbs was right. The team deserved to hear it from me."

"How did it go?"

"About as well as can be expected." Tony sighed again. "Gibbs yelled, McGee and Ziva didn't believe me, Abby cried. Vance turned up and defended me though, which was a nice surprise."

"I thought he didn't like you?" JJ commented.

"He didn't like Agent Tony," Tony replied. "Lieutenant Colonel Dinozzo though…"

"Which is understandable, I guess."

"Yeah." Tony agreed. "I didn't like Agent Tony either."

"So you've got three months leave?" JJ asked. "We'll be able to go to Mom and Dad's for Thanksgiving and Christmas again."

"Yeah." Tony sounded happy. "I have two days to write up my reports and then two meetings booked for Monday morning. One of which is with the president."

JJ twisted around to see his face. "Seriously?"

"I know." Tony agreed. "It's a terrifying thought."

"And an amazing one." JJ pointed out, settling against him again. "The president wants to meet you."

"And apparently they're promoting me to colonel." Tony added.

"Wow." JJ smiled. "They must be really pleased that you managed to take down Davenport."

"I suppose." Tony agreed. "I'm just glad it's over."

"Me too." JJ agreed. "We'll be able to meet for lunch and have the team over for dinner and tell Andrea and Randy's kids that you're a marine."

"We should have just told them that in the first place, like we did your team." Tony commented. "It would be much less confusing for them."

JJ shrugged. "No point worrying about it now."

Tony was silent for a while. "It's strange to think that I'll never have to be Agent Dinozzo again."

"Unless you decide to leave the marines and come work with me." JJ grinned. "You could take up Hotch's offer and we could be Doctor Agent and Agent Dinozzo, FBI."

Tony laughed. "You think that sounds better than Doctor Colonel and Agent Dinozzo?"

"That has a nice ring to it too." JJ admitted. "That's another nice thing to this being over. Our marriage paperwork can be filed and I can officially take your name."

"Even at work?" Tony asked questioningly.

"Yes." JJ nodded. "I've dreamt of getting married and taking my husband's name since I was a girl. It's sort of a dream come true."

"Do you want me to work for the FBI?" Tony asked after a minute.

"I don't mind." JJ answered. "There are pros and cons. It would be nice to see you at work every day, and you'd be a great addition to the team. But when the team goes on cases there'd be no one to look after Twinkle Toes."

"Maybe I could resign my commission and stay at home with Twinkle Toes." Tony suggested. "I could write a book."

"You love the marines." JJ told him. "Let's not make any big decisions yet. Take the next couple of months to wind down, find out what your orders will be, and then decide."

Tony sighed. "I'm just so tired."

"Good thing you've got three months off then." JJ told him. "Finish off your paper work, go meet the president, and then sleep for a week."

"That sounds nice." Tony told her. "You should ring you parents tonight, let them know the good news."

"They're going to be so excited." JJ smiled. "I know that mom was really worried about you still being undercover when Twinkle Toes is born. She thought the stress of it might be too much for us."

"Its good timing." Tony agreed. "I'm looking forward to spending some quality time with Twinkle Toes."

"Did you have any more name ideas this week?" JJ asked.

"Joshua, maybe." Tony suggested. "I think I like it better than Robert even. You?"

"Caroline is still my favourite." JJ commented. "I like Joshua. It's definitely better than Robert."

"Caroline." Tony sounded out. "It's cute."

"I know I've said it before," JJ said. "But I'm relieved that you're not determined to name a son Anthony. We'd probably end up calling him Ant or something."

"I don't want any of our children feeling as though they're a second model." Tony told her. "My dad always called me junior and it made me feel as though he expected me to be a younger him. Which, seeing as how my dad disowned me when I was fifteen and hasn't spoken to me since I became a marine, probably wasn't far from the truth."

"Wait, children?" JJ grinned. "As in multiple?"

Tony shifted. "I'd like a few. You're from a big family, and I always wished I had at least one sibling."

"I've always imagined having three or four." JJ offered. "Though I might change my mind after I've experienced labour."

Tony laughed. "Did you want a hot drink? I think our ones will have gone cold by now."

JJ looked over at the drinks on the table. "We could warm them up. You said you were bringing home the left over cake?"

"It's on the bench." Tony told her. "You can stay here if you like, I'll put the drinks in the microwave and bring you some cake."

"Sounds good." JJ sat up, so that Tony could extricate himself from behind her, before lying down where he had been sitting. "How about we order dinner tonight. I don't really feel like cooking."

"Sure."

JJ stared at the ceiling and listened to the noises Tony was making in the kitchen with a smile. Tony was a great husband and she had no doubt that when Twinkle Toes eventually made an appearance, Tony would be a fantastic daddy. She was so glad that she had worked up the courage to give him her number that day at Roger's Café.

It was hard to believe that they had first met only two and a half years ago. It had been a wonderful two and a half years, but hard at the same time with Tony's assignment at NCIS always there in the background. But now Tony's assignment was really over and he would never have to go undercover like that again. They had the rest of their lives to enjoy one another's company without secrets and NCIS getting in the way – it was a wonderful thought.

I am sorry to announce that this is the last part of 'Tony Dinozzo, Undercover Marine'. There is a tiny chance that I may come back one day and add a few more parts, but if I do it won't be any time soon.

Thank you very much for all your support and encouragement. I am so glad you enjoyed this story.

I know that many of you were hoping that I would continue this story to show Twinkle-Toe's birth, and perhaps Tony working at the FBI. So if anyone else would like to take up the mantle and write some stories attached to this series I would be very happy to put a link to them on this page. I only ask that you keep Tony and JJ together and keep the rating under NC-17. :)
