The security officer at the front desk appeared to hesitate before handing over the visitor's pass. Even though the kid was on the approved list, he had a hard time believing that the young man was who he claimed to be. Then again, anything was possible, especially with that group.

TJ took the pass and nodded at the guard before heading to the elevator. It had been awhile since he'd visited his dad at work, but he seriously doubted that much had changed. When he reached the floor he stepped out and made his way to his dad's desk. Realizing that no one was around at the moment, he took a seat and used the time to check his email.

Special Agent Anthony DiNozzo took a seat at his desk, and then looked up, frowning at the person behind his boss' desk. "Excuse me. Who are you and what are you doing?"

Before either one could say anything else, Special Agent Leroy Jethro Gibbs, came into the area. He looked at DiNozzo and raised an eyebrow. "Problem DiNozzo?"

"Kinda boss. Trying to figure out who the kid is and what he's doing here."

Gibbs nodded. "Smart thing to do, but I'll take care of him." He looked over at the boy. "Thomas James, follow me." He started walking towards the elevator.

He got up and followed him, not saying anything until he was inside the elevator. "You know dad, it's a lot easier to call me TJ."

His dad, former Marine Corps Gunnery Sergeant turned NCIS Special Agent, just grinned. "I know, but it's not as much fun." Gibbs pulled his son to him and gave him a hug before ruffling his hair. "How you doing kiddo?"

"Better now that I'm here with you. Although, the guard downstairs kinda looked at me funny when he was checking out my info before giving me the visitor's pass. So where are we going anyway?"

"To see Ducky. I want him to check you over as a precaution, then I'll introduce you to Abby and you can hang around with her until I get done upstairs."

"Okay. So who was the guy upstairs?"

"That's my Senior Field Agent, Anthony DiNozzo, but you can call him Tony if you want."

"Cool." He laughed softly. "Think his eyebrows about hit the roof when he saw me sitting at your computer."

Gibbs grinned. "I can bet they did. I'll have to harass him a bit about letting people just sit at my desk. Before we leave, I'll bring the others down, including Tony and introduce you to them. Until then, if you see one of them coming, just stay in Abby's inner lab or you can go visit Ducky."

He nodded. "I can use the stairway --" He stopped as a slap landed upside his head. "Or I can just take the secondary elevator."

"That's the better idea." When the elevator stopped, he exited and headed over to autopsy. "Ducky, got a customer for you."

Doctor Donald "Ducky" Mallard, frowned as he turned to face Jethro. "I failed to receive a phone call about a dead body Jethro."

"That's because I'm not dead Ducky." TJ stepped out from behind his dad and grinned at the ME.

"Thomas James. Why your father failed to mention that you were coming into town for a visit." He stepped forward and hugged the boy, frowning again when he felt him flinch. "What have you done to yourself?"

"That's why I brought him down to see you Ducky. He's going to be living with me from now on and I want you to give him a full physical with blood work and X-rays. Seems his mom's last boyfriend didn't want to send him back to the boarding school and decided to use him for a punching bag. So, Ashley sent him to me along with papers giving me full custody and terminated her parental rights." He held up his hands to prevent Ducky's next statement. "The last part falls to TJ here. He wanted those terms thrown in, not his mom. She agreed to them. Course, she didn't call me until he was already on the bus here."

"Well, he's here now and that's all that matters." He turned to the boy again. "All right, Thomas, up on the table with you."

"Bring him over to Abby's lab when you get done Ducky." Gibbs left then, first to get a refill and then to go talk to Abby before his son joined him again.

TJ watched his dad go, and then hopped up on the empty autopsy table. "I can tell you already that I might have a few bruised ribs."

Ducky frowned at him. "Her boyfriend?" At the boy's nod, he sighed. "All right then, let me help you with your shirt and we'll go from there." With that, he started helping the boy so he could do the exam.

Former Secret Service Agent turned NCIS Kate Todd and Special Agent Tim McGee entered the bullpen and stopped at the look on Tony's face. Kate broke the silence first. "What's wrong Tony? You look like you've just seen a ghost."

Tony shook his head, frowning. "Not a ghost. Something much worse."

McGee spoke up then. "What could be worse than that?"

"A miniature Gibbs."

Kate raised an eyebrow at him. "What did you drink at lunch Tony?"

"I haven't been to lunch yet Kate, but when I came in from getting that report from the file room, there was a teenage boy sitting at Gibbs' desk like it was nothing. Before I got a chance to ask much more than who he was and what he was doing here, Gibbs came in, agreed with me that it might be a problem not knowing who the boy was, said 'Thomas James come with me', and left with the boy." He looked at each of his co-workers in turn. "He looked exactly like I would expect Gibbs to have looked at that age: dark hair, blue eyes, about 5' 7", excellent shape, but about 120lbs. I'd say he was around 15 or 16."

McGee nodded. "Huh, sounds like he might know the boy. I'm sure he'll tell us if it's something we need to worry about."

"Yeah, but it just has me curious about who the boy is."

The others nodded at that before they all settled back to working on their reports, what Tony had seen and told them pushed to the back of their minds, at least for now."

Gibbs raised an eyebrow when he walked into Abby's lab at the music she was playing. He turned it off and looked at her. "Thought you were done with that group."

Abigail "Abby" Sciuto grinned at her boss. "I was, but I really like that song. So, what have you got for me?"

"Actually, no evidence this time, but I do have something I need to talk to you about."

She frowned. "Sounds serious."

"Well, it is, at least in a way." He paused for a moment. "Right before I shipped out to my first assignment, I met a girl on leave. She was really nice. Didn't see her again until about 17 years ago, and we had a pretty good time. Nine months after our last night together, she called me to let me know that I had a son. She refused to marry me, but promised I could see him. That lasted for a few years, but then she moved and refused to tell me where. When I finally tracked her down, she told me that if I came near her or the boy, she'd have me thrown in jail, so I just left them alone. I kept tabs on them though, but didn't attempt to see my son. When I left in such a hurry yesterday, it was because she called. Told me that my son was on a bus to come live with me and that she never wanted to hear from either of us again. I picked him up at the bus station and we spent the rest of yesterday getting re-acquainted."

Abby's eyebrows shot up. "You've got a 16yo son? Here?!"

He nodded. "Right now, Ducky's giving him a full physical. Seems her most recent boyfriend wasn't fond of TJ and let the boy know it rather frequently. He was a bit bruised when he got here so I want it all documented. Also, she didn't send any of his medical records and he says it's been a few years since he saw a doctor."

"Does anyone else know?"

Gibbs grinned. "Tony saw him and knows his name, but not who he is. TJ came in by himself since I let him sleep in this morning and was checking his email on my computer. Tony was just starting to question him when I came out of MTAC and saw him. Didn't give him a chance to answer Tony before I took him down to see Ducky."

Abby chuckled at that. "Tony's probably driving McGee and Kate nuts trying to figure out who he is."

"I'll tell them before we go home for the night, but once Ducky is done with TJ, I'm going to let him stay in here with you if that's okay."

"You mean I get to show him all my cool stuff first?"

"That you do Abs, just know that he's a quick learner and might run you crazy with questions."

"Not a problem boss man." Her phone rang then and she answered it. A few seconds later she turned to Gibbs. "Ducky says he's done if you want to go pick Thomas up. Figured it'd be better if you come there instead of him sending TJ here."

Gibbs nodded. "His full name is Thomas James Leroy Gibbs, but he likes to be called TJ." He stood up. "See you in a few minutes."

While Gibbs was talking to Abby, Ducky had finished his exam of TJ. He frowned as he reviewed the boy's X-rays and then moved back over to him. "When did you fall on your wrist Thomas?"

TJ frowned as he thought about it. "Couple of weeks ago, why?"

"You have a bad break in it that has started to set wrong."

"That why it still bothers me?"

"It would be one reason, definitely. If it's not fixed properly, you might lose the use of it."

Gibbs picked that time to enter the room and frowned. "Lose the use of what Ducky?"

"Thomas here has a rather bad fracture in his left wrist that has started to heal incorrectly. If it's not fixed soon, he may lose some or full use of it."

"How would you need to fix it?"

"It would be best to have it surgically rebroken and then a small plate put into place to help it heal correctly."

TJ paled. "No hospitals." He looked at his dad. "You promised me no hospitals."

Gibbs walked over to him. "I said no hospitals if Ducky said that it was unnecessary. This isn't something to fool around with kiddo."

He jerked away from his dad and hopped off the table. "NO! I won't go!" He took off running out the door.

Gibbs shook his head and followed after him. "Tommy, come back here!" He never thought he'd see the day when he'd be chasing one of his own through the building.

Tony was on his way to Abby's lab to check up on some results when he was almost run over by the boy he'd seen earlier. "Easy kiddo, where are you going in such a hurry?" His hands instinctively settled on the boy's shoulders. The next minute he found himself flat on the floor, the kid on his chest with wrists crossed in his collar and pushing down. To say that he was stunned would definitely be an understatement at the moment.

Gibbs rounded the corner near Abby's lab and spotted his son trying to choke his Senior Field Agent. "Thomas James, stop right now!" When he didn't get a response from the boy, he moved closer. "Thomas James Leroy Gibbs let him up this instant!"

The use of his full name accompanied by his dad's tone finally got through to TJ and he loosened his grip on the man underneath him moments before he collapsed to the floor.

DiNozzo immediately tried to catch the kid as he started to tilt sideways to keep him from hitting his head as Gibbs knelt down beside them.

"You okay Tony?" Gibbs asked as he stretched his son out on the floor.

"Little sore, but I'm okay. Who is he boss?"

"My son." He looked up at his agent. "Help me get him to Ducky and I'll explain."

Twenty minutes later, Anthony DiNozzo was speechless, a feat seldom accomplished by anyone.

Ducky grinned at the stunned agent. "It takes some getting used to Anthony, but once you get down to it, Thomas is pretty much a smaller version of his father."

Gibbs grinned at that comment. "Yeah, in some ways he really is."

Tony snorted at that. "In more than some, boss. He flipped me without me even realizing what happened right before he started choking me with my own shirt. I know he didn't learn that in any martial arts school."

He shook his head. "No, he learned that at the military boarding academy his mom had been sending him to before she met her latest boyfriend."

"Figures it'd be something like that." He looked over at Ducky. "Is he okay?"

"Yes, Thomas just overexerted himself considering the fact that he has several bruised ribs, a couple of cracked ones, mild concussion and his left wrist is fractured." He looked at Jethro. "Speaking of which, he rebroke it along the same fracture line, so there is no longer a need for him to go to the hospital. I can set it and apply a cast here if Abby will let me have some of her casting items."

"So that's what snapped. Thought it was something of mine at first."

Gibbs sighed. "I'll go ask Abby for some and let her come on up here to meet him." He looked at Tony. "Help Ducky keep an eye on him, but I wouldn't try to restrain him."

"No problem with that part boss." Tony watched him leave, and then looked at Ducky.

"Why do I get the feeling that everything around here is about to change?"

"Because my dear boy, having a teenager around always tends to liven things up, and not always in a good way."

Abby looked up when Gibbs walked into the lab and raised an eyebrow at him. "Everything okay?"

"Not really. Ducky needs to know if he can borrow some of your cast material." He told her what had happened with TJ and Tony.

"Yeah, no problem Gibbs." She gathered the stuff Ducky would need, and then added a couple different colors of the fiberglass. "Figured he can choose what color he wants to live with for the next few weeks."

"Appreciate it Abs." He grinned at her. "Why don't you come with me and meet him? Tony's with him and Ducky right now."

She grinned. "I'd love to." After turning one of her machines to standby she started walking with him.

Shortly after Gibbs left, TJ woke up, frowning at the cold feeling on his wrist.

"Easy Thomas, you broke your wrist again when you flipped Anthony. Surgery is no longer necessary my boy and your dad is bringing me back the stuff so that I can finish setting it and put it in a cast. The cold you are feeling is from an ice pack so that we can keep the swelling down until then."

TJ sighed. "Can I sit up a bit? The table's kinda cold and it's making my ribs hurt more."

Tony helped him sit up, letting the boy lean back against him. "I'm sorry I tried to stop you like that."

"It's okay, you didn't know. Besides, I probably shouldn't have run from my dad like that in the first place."

"Good to hear you say that kiddo, but you're still grounded." Gibbs ruffled his hair as he came back into the room with Abby and the supplies Ducky needed. "Here ya go Ducky. Abby added a couple of colors for the cast."

"Ah, good. I'll get this started and then review the X-rays again before I set his wrist, then we can cast it and he'll be done."

TJ looked up at his dad from he rested against Tony. "Sorry for running off like that."

"I know, but for now just relax and let Ducky fix your wrist, then we'll go home." He put a hand on Abby's shoulder. "TJ, this is Abby Sciuto. Abby, this is my son, TJ."

He gave her a small grin. "Hi Abby."

"Hello yourself. I have to admit that I was a little surprised when Gibbs said that he had 16yo son."

"Yeah well, my mom wasn't real fond of him, which is why I convinced her that it'd be a good idea to just terminate her rights to me instead of anything else. Pretty much just told her that if she tried to fight him about it, I'd have to give all the evidence I have against Daniel to dad. She didn't like that too much, so she signed the papers in front of a notary and put me on a bus." He chuckled softly. "Although, she was supposed to call dad once I was on the bus, not wait almost 2 days. By the time she finally called, I was already at the bus station here and trying to figure out where the best place to call dad would be."

Gibbs snorted. "Soon as she told me when she'd put him on the bus, I called the bus station to have them page him and give him the message that I was on my way to pick him up."

Abby shook her head. "Well, you're definitely more talkative than your dad is, that's for sure."

TJ shrugged. "Only when I want to be, otherwise I can be just as stingy with my words as him."

Ducky walked back over to them. "Okay Thomas, we got lucky this time. When you rebroke it, it broke on the exact same path as before, but when you proceeded to choke Anthony, you managed to somehow align it properly. Now, all I have to do is have your father hold it in alignment while I start casting it, just as precaution."

He looked up as his dad came over and gently took hold of his wrist. "When we get done here, I need to file a bit of paperwork before we can go home."
