Ok, this is because of the alarmingly few Ziva de-aged fics out there. Sorry if the intro is bad, I just needed her in the situation. Thanks.

Ziva pulled up outside the suspect's house, flying out of her car and only pausing on front of the door, one hand on her gun. Gibbs, Tony and McGee met her before she stormed in, the four of them filing in and clearing the house. She took the first room to their left, what appeared to be a living room of sorts that led off to another room. She continued along the way. The only sound she heard as she cleared the second room was McGee shouting that his was fine, Tony and Gibbs following quickly. She hadn't even realised the suspect was in there before she was shot, collapsing in a heap. The others were quick to take the man out before he could disappear out the back, Gibbs rushing over to Ziva and checking her pulse. There was a steady heartbeat.

"Is that a tranquiliser?" McGee asked, pointing to the dart in Ziva's back. "What good would a tranquiliser do? He's already killed five people. What made us different?"

"Federal agents McGee, don't go down well with the courts," Tony offered, leaving to call an ambulance.

"Shouldn't we take the dart out?" McGee continued, "I mean, wont it be better-"

"We leave it as it is," Gibbs replied, standing up. "The medics will do their job."

The ambulance arrived five minutes later, removed the dart and took Ziva away to the nearest hospital. Tony went with her and McGee and Gibbs collected evidence, Ducky and Jimmy dealing with the suspect's body.

At the hospital Tony had been left waiting outside Ziva's room while the doctors did various tests. An older man came out slightly startled looking. Before talking to him, he pushed his oval glasses further up his nose and flattened out his greying hair. It wouldn't be long until he retired.

"Um, hello, um," The doctor stuttered, glancing back at her room. Oh God, what's happened? "My name is Doctor Paterson and I am in charge of your partner's, um, case. After only being here a few minutes she began to rapidly-um-de-age."-Doctor Paterson tried to gauge Tony's reaction-"We have performed numerous tests and your partner seems to have regressed to be about four, five years old."-He took in Tony's face that had morphed into an odd disbelief-"You may want to see for yourself."

Tony followed the man into Ziva's room. He found a small child lying unconscious in the hospital bed, wild curls spread across the pillow. He had seen pictures of Ziva as a child. That was definitely Ziva. "We haven't exactly worked out how this occurred however we do have specialists working on the dart that penetrated her. She is sedated for now, she should be waking up in a half hour or so."

Tony ran his hand through his short hair and glanced around. What was he supposed to tell Gibbs? What was he supposed to tell anyone? He would have to call him. He stepped out of the room to call, being intentionally vague. He didn't want to tell him everything was fine because everything was definitely not fine however he didn't want to make it sound Ziva was in any fatal danger, she could be, but he didn't know. When Gibbs agreed to come over, he hung up, sitting in the spare seat beside the hospital bed.

Gibbs came into the room, his eyes immediately falling on Ziva. He almost thought he had the wrong room however he caught Tony's nervous expression. He stood waiting for him to explain whatever was going on.

"This is Ziva," Was all he could say.

Gibbs came over, examining her face. She held a striking similarity to his agent. She began to wake, a small moan escaping her lips. Her eyes flicked open, taking in the rest of the room. She was in hospital.

"Was I shot?" Ziva began, suddenly perking up. Her voice was higher pitched than normal. She glanced down, her eyes falling to her hands. She lifted them up, glancing over the little things. They pounced on her flat chest before flinging the hospital blanket off of her. "What-what-what-"

She began to shake in fear. Tony's first thought was that she was very un-Ziva like however that was to be expected when one suddenly finds themselves as a child. Gibbs tried to comfort her which only aided her a little.

"We're gonna fix this Ziver," He assured, "Promise."

She let out a long breath, her eyes never leaving his. She radiated fear, could practically breath the terror. He didn't blame her either. He couldn't imagine what he would do if he was in her situation. Doctor Paterson returned, having calmed down himself, and stood beside Ziva's bed.

"We have finished our biological tests on Miss David," He informed them, "Miss David may I ask you what you last remember?"

"I-I was clearing the room," She told him. "I must have got shot, I wiped out."

"Blanked," Tony corrected on instinct.

Gibbs shot him a glare, Ziva and the doctor ignoring him. "Just as we suspected. Ziva has returned to a child-like state while retaining her memories. She will have a child-like mentality in a short period of time. Effectively she will be a four-year-old with the memories of a twenty-nine year old."

"How do we fix this?" Gibbs snapped.

"We are working on it." Doctor Paterson assured him. "We would like to keep Ziva overnight however she is in perfectly good health and may be able to be released in the morning,"-he turned to leave before adding quickly-"into the custody of an adult."

Ziva just blinked in the direction of the doctor. So what, she was a child again? She felt a surge of misery fill her however she managed to suppress it. It was harder to do than usual and she felt her bottom lip quiver. In a few hours suppressing her emotion would not be an easy thing to do.
