A NCIS fanfic "Air guitar"

by Kiamii

Reason for title: Air guitar was something that extremely fit Tony's personality, especially after seeing the episode where he participated in the contest for Air guitar, Ziva later entering her own after the case had been solved.

Chapter One "Only Way"

Note: I know there's another de-aged Tony story, I think it's Sweet Lullaby. It was really sweet, though I just wanted the idea of de-aging Tony through a drug and a fatherly Gibbs, that's probably one of the only similarities and if you've got a problem with it, go bugger away.

Gibbs was speechless. This had gone even above and beyond DiNozzo's usual "getting hurt" phase. He wasn't in the Bethesda general emergency division... he was in the freaking pediatrics ward. He wasn't standing in front of his plague-ridden, shot agent, but behind glass facing an unconscious 10-month-old baby boy. One who had once been Anthony DiNozzo. A little ways from him was Donald Mallard and Brad Pitt, discussing the events that had come from it. Gibbs turned to them as he heard his name called, his eyes still somewhat on the boy sleeping. God this was just plain twilight zone.

"Ah Jethro," Ducky said with a sigh, "This 'simplifier' as they call it is a drug containing Sodium thiopental which can act as a rapid-onset short-acting barbiturate general anesthetic. Rather than the effects it was due to act as, it was able to act as a brain-damaging compound which, in a side-effect, reverted young Anthony's brain, though only partially-"

"To the point, Duck," Gibbs said, his eyes narrowing.

"Meaning he'd have the reactions of that of his now physical age thanks to the combination of Medroxyprogesterone 17-acetate -or MPA as it is called- which, when worked the wrong way as it was in this scenario, began to eat away at the hormones of the 40-year-old man and before we know it, his body reacts to the lack of hormones and voila, we have a 10-month-old boy by the name of Anthony, with the rather unexpected twist of his mind remaining intact, as was experimented by the late John Coopman, who had been in the midst of creating an antidote." finished Ducky, "This reminds me of a time when MPA had been used to castrate sex offenders. Though who knew when mixed with Sodium thiopental, it'd cause this reaction."

"So DiNozzo is a baby... with his mind?" Gibbs asked, doubtfully. Ducky nodded and tsked, the two watching as Brad entered the nursery room to tend to DiNozzo. Apparently small signs of the plague had appeared in the former agent's lungs, though not as severe as it used to be. Brad had forcibly made himself the pediatric doctor to DiNozzo, unwilling to let his friend be poked and prodded by an ignorant doctor. The only reason they'd found the combo-drug was because it had been created legally, by an agent named John Coopman. It was an experimental drug they had been planning to create for a mission. Unfortunately the test results had not been completed when the man died. Tony had been chasing the suspect of the victim when he'd fallen, the suspect taking advantage and forcing the pill into Tony's mouth, running afterwards.

They stayed silent for a moment, each wondering what they'd tell the rest of the team and Tony himself...

Blackness. That was all Tony could see. He could hear voices, and something beeping in the background. He struggled to get his eyes open, his nose flaring with the scent of a hospital. Great. He'd probably gotten shot again. The last thing he remembered was chasing a suspect before he lost conscious.

"He's waking," a soft voice stated and Tony wanted to sit up and say 'tada' but his body was refusing to do as asked. He shifted and he let out a groan, which in his mind had sounded normal but Tony only heard a whimper. Was a child in here? Slowly, he managed to open his bottle deep green eyes to find himself staring widely at the scene in front of him. Everything was bright! Colorful! What the hell?

'Where am I?' he tried to ask but it came out gibberish and gargled.

"Easy there Tone," soothed someone familiar but Tony could see them until Gibbs came into place. Did the boss man just call him Tone? A pet name? What was he in, the twilight zone!

"Bu-ohh" Tony attempted to say boss, but it came out as that, to Tony's panic. Had something happened to his vocal chords? And why in McGoo's pants was his voice so... high? He squirmed and his foot hit against a railing. He glanced down only to feel a jolt of shock course through him. He could see his toes! They were tiny and squeezed together! He tries to wiggle them and saw his toes twitch a little. He felt an emotional bubble well up in his stomach and he couldn't stop the crying that he began to undergo, wailing and thrashing. Oh dear god. He was a baby. A flipping baby!

He felt someone pick him up and put him to their chest, reminding Tony of his small stature. He continued crying as the person holding him began to gently rub his back in small circles. Strangely enough, it felt soothing and calming, slowing Tony's tears and the former agent could think clearly again through his groggy mind.

"Uhh appeee?" Tony sleepily said.

"What happened?" Gibbs guessed, continuing at Tony's nod, "The pill the suspect dosed you with regressed your body. You're 10 months old now."

"Wuy?" Tony asked, pleased he could at least say that word almost correctly.

"Something about chemicals. Go back to sleep Tone, the team is coming over soon," Gibbs said. Tony simply nodded, worn out from the crying he'd done earlier, though he was mortified he'd even shed a tear over it. Within moments he was asleep, though his worry was still plaguing him clear as day.

Gibbs sighed and set his agent back in the crib. He'd just gotten through talking to the director who'd been on the phone with the SecNav. The pill had been intended for mission use and the original age that was supposed to be the result had been six years of age. Fortunately -or fortunately for the SecNav- the suspect they were interrogating had two sons. One was six and the other was about 11 months old. The mission was simple. Get the 'child' agent to make friends with the son of the suspect and the 'father' agent would be able to study the man, find out if he was actually who he said he was while under the guise of an overprotective parent. That meant Tony would have to be the agent on the mission, since that had been a prototype drug. Gibbs, after persuasion, relented and said it was up to Tony. If his agent -which he knew the man would- said yes, Gibbs and his team -McGee and Ziva- would be the 'family' that accompanied the regressed agent. In London, England.

He looked down at the sleeping agent in front of him. God, DiNozzo looked so young and innocent right now. He reminded him of his Kelly, when she'd been that age. So small and frail, oblivious to the cruelty of the world. He shook his head, determined to clear the memories, before going to inform his team of what was happening. God help him on this. The mission seemed okay enough, but what Gibbs worried about was if anyone could retain Coopman's notes and create the antidote.

Someone really must hate DiNozzo, Gibbs mused as he walked out the door after a final glance at the baby.

Author's Note: Like it? It's short for the prologue but it's intended to show what happened sort of. Tony is going to fight against everything just so you know. If you want me to continue with this, review. Also, I have no idea what idioms are used in England or the UK so if you are british or know british, can you give me a few idioms? Or even words that are different in the USA than UK. Like torch is flashlight. Let's just say, the team is going to go through hell in the UK. For the record, the explanation for the drug was made up. I used two chemicals and mixed em up for fun in my story. That's it.
