Alright. Chapter one. There is a prologue to this story, I posted it separately. It is called Positive. This is Mpreg, and eventual McGibbs. I may have some problems with timelines of the show, in those cases please let me know so I can try fix them. Roughly this takes place somewhere around season 7 I believe is the season after Somalia? Anyway, in this male pregnancy is sort of a more common thing. I hope you enjoy and please give it a review. :)

I do not own NCIS or it's characters.

"This stays between us, right?" Tim hesitated in front of the older man. "Like, patient doctor confidentiality?"

Dr. Ducky Mallard smiled softly at the young man sitting across from him in his office down in Autopsy. The young agent had just told him what had transpired between himself and Agent Gibbs. Ducky was not surprised. He saw the looks between the two men over the years, knew they wanted to be together. But he also knew that Jethro was too stubborn and had that blasted 'Rule 12' to hide behind, and Timothy was too shy to actually act upon his desires. Obviously both had now crossed that line they had drawn all those years ago.

Ducky had not been surprised it had finally happened, he knew many agents throughout the office (including their own teammates) had bets on how long it would take for the two men to get their acts together and realize what they both wanted was one another, and finally, finally, get together. Ducky himself had only shook his head when he learned that even his medical assistant, Jimmy Palmer, had taken a bet when and where it would happen.

Of course, when young Timothy had come to him after their latest case had finished up, and told him his newest development, Ducky could say he was very surprised. Knowing that the young agent was now pregnant with Jethro's child, Ducky was worried how this would end for the two agents and friends. How this would change everything for them, not only as teammates, but has friends, and maybe even lovers.

"Of course, Timothy." Ducky nodded, and Tim sighed in relief.

"I'm just not ready for them to know." Tim added quickly, and then quietly, "Or him."

"You have to tell him sooner or later, Timothy. You can't be out in the field now."

Tim nodded, "I know. I have a doctor's appointment tomorrow. I need proof before I approach Gibbs. He already knows I'm going to be late for work."

Ducky sighed, knowing that was the best he was going to get from the younger man. Timothy was just as stubborn as Jethro. The medical examiner watched as Timothy stood from the couch, thanked him, and then walked out the door, heading back to his desk, obviously to grab his backpack and head home for the evening.

When Tim got into work shortly after ten in the morning, a half hour after his doctor's appointment, he got straight to work - with cold cases. The pregnancy test the doctor had ordered and an ultrasound scan tucked away in his backpack, Tim got straight to work. He had finished his report from their case the night before, before going down to talk with Ducky. Going to see the medical examiner had been his second thing on the mental check list he had made for himself. The third had been the doctor's appointment, and the fourth? Gibbs.

He knew the older man needed to know, he had a right to know he was going to be a father again. Tim was just scared of how he would react. The senior agent had barely spoken to Tim other then barking orders at him since that night. Sighing deeply, Tim looked across his desk to his boss, who was currently reading one of their reports from last night, clearly not happy with it. Tim would give money that it was DiNozzo's.

Taking a deep breath, Tim stood. They weren't in the middle of a case so it was now or never. Anything could happen and he wanted to get this over with as soon as possible. Tony and Ziva were at their own desks working on their own cold cases. Stepping up to Gibbs' desk, Tim was nervous. He didn't say a word, waiting for Gibbs to notice him. It didn't take long.

"Um.. uh.. can.. uh."

"Spit it out McGee." Gibbs growled, clearly frustrated that Tim had reverted back to his old ways of stuttering.

Tim could feel Tony and Ziva watched now.

"Could we talk? In Private?" Tim rushed to speak, not wanting to annoy Gibbs anymore then what he seemed to already be, "Please."

Gibbs took a moment to look at his youngest agent before giving a curt nod and standing up. Before either could move, Gibbs' desk phone rang. Tim watched as the older man answered his phone, said two words, and hung it back up.

"Gear up, we've got a dead marine." Gibbs didn't even look at Tim as he grabbed his weapon and coat before rounding his desk and heading for the elevator, not waiting for the rest of them.

Tony and Ziva already had their gear and were steps behind Gibbs before Tim could even move. He knew he shouldn't be going with them, but without them knowing the reason why yet, he didn't see no harm in going.

Tim stepped into Abby's lab with the evidence gathered at the crime scene for her. Her back was too him but as soon as he cleared his throat she turned with a smile, only to frown.

"McGee! What happened?"

Tim closed his eyes as she bustled over to him and cupping his face, looking over the split lip and slightly bruised cheek.

"It's nothing." Tim smiled at Abby to convey that he was alright. "Just a disgruntled witness turned suspect."

Abby looked at him, not believing a word he said about it being nothing. "Timmy?"

Tim sighed, knowing he wouldn't be able to get anything past his best friend. "I got shoved and punched, once, before Gibbs had the guy in handcuffs. Really, I'm fine. I will be."

"If you're sure?"

Tim smiled and nodded. "I got evidence for you."

Nodding, Abby took the box from her best friend and turned to the table, ready to sort through it. Tim hesitated, knowing he needed to get back to his desk. He had a laptop from the deceased to rummage through, but he also really needed someone else to talk too. Looking at Abby, he made his decision.

"I'm pregnant and Gibbs is the father." He blurted out before he could chicken out.

He watched Abby freeze in her motions before a squeal erupted and she spun on her heels and wrapped her arms around him. It felt nice and Tim melted into her, his own arms snaking around her middle. Before they were friends, before they were teammates, they had been quick lovers. Tim missed it sometimes, but knew it was for the best. They weren't right for each other in that way.

"Oh you guys are going to be such good daddies!" Abby kissed his cheek before pulling away.

Tim watched as relisation dawned across her face and he knew what was coming.

"You're pregnant. You're pregnant and you went out into the field. You're pregnant with Gibbs' baby and he let you out in the field."

Tim had to place his hands on her shoulders to stop her from storming off, he figured probably to yell at Gibbs for something he had no idea about. Before he could speak, there was another voice behind him and he froze.

"You're pregnant?"

Tim turned to look at the older man, his big brother and sometimes protector, sometimes tormenter. Tony.

"You and Gibbs finally did it and now you're pregnant." Tony stated more then asked as he stepped closer to the pair already in the lab. "But Gibbs doesn't know or else you'd be sitting at your desk, not getting punched by a guy twice your size. Oh man Probie," Tony smiled into a wince, "Gibbs is going to kill you."

Tim sighed, "I know."

"So who won the bet?" Abby asked

Tim groaned. He knew all about the bet made at his and Gibbs' expense. He was pretty sure even Gibbs knew. Tim had overheard Tony and another agent discussing it about four months ago. He himself and put down twenty dollars on it never happening.

"I know I didn't. I said never but here we are a month later."

Tony smirked, "Vance."

Tim and Abby both looked at the other agent in surprise. Tony just nodded.

"He said it would happen on a weekend off for the team, and by my calculations, that was four weeks ago. So when are you going to tell him? Oh was that what you were stammering about earlier when we got the call?"

Tim nodded, "I don't know how he's going to react. He hasn't exactly been speaking to me unless to bark orders or yell at me."

"So you two aren't still...?"

"No Tony. Rule 12."

The ringing of Tony's phone seized the conversation. He watched the older man look at the caller ID and wince, showing it to Tim and Abby. Gibbs.

Tony quickly answered, "Hey Boss."

It was clear Tim and Abby heard the other man yell at Tony to get his and Tim's asses back to the bullpen and back to work before hanging up. Tony clipped his phone back to his belt and grabbed Tim's shoulder to gently tug him out of the goth's lab. Abby gave them a quick little wave before returning to her own work.

When they were in the elevator Tony turned to Tim, "Whatever happens just know that I'm here for you buddy."

Tim smiled and nodded, "Thanks Tony."
