Note: Because in this chapter, a few people end up going even further back in the past, Jr after the name signifies that it is the person that is in the right time, Sr is someone from the future, to lessen confusion. Capisc?

Haunted

Kate and Tony's genius son and daughter, Stefan and Fiorella, create a time machine. But something goes horribly wrong and they end up in 2006, in a world where Kate died.

Chapter Three: Location

Maria was now getting impatient. "I want my Mommy!"

"DiNozzo, deal with it," Gibbs commanded, "McGee, follow me." They marched off toward the elevator, leaving Tony alone with Stefan and a wailing Maria.

"Boss! Boss," Tony shouted after them. "How?"

"I don't know, DiNozzo! Tell her to shut up or something!" was Gibb's exasperated retort.

Tony looked at Stefan, only now noticing the resemblance between him and Stefan. Stefan nodded. "It works. Just make sure you call her Gabby, and speak in Italian."

Tony looked doubtful. Stefan sighed, "Sta'zitta, Gabby. That's all you have to say, Papa."

Tony was doubtful. "Sta'zitta Gabby," he repeated.

"Si, Papa." Maria said obediently, and slammed her mouth closed. Noticing Tony still staring at her, she came up to him and sat on his knee. "Tutto bene, Papa?"

"Si. Non che male." Tony answered robotically.

"You don't sound okay," she muttered under her breath, scrambling back off and perching herself precariously on Ziva's chair.

"See, Papa," Stefan smiled. "You're doing fine."

Tony finally voiced what he had been thinking for a while now. "Stefan, right?" Stefan nodded. "How does Ella look exactly like K-Kate when Kate is dead?"

Stefan shrugged. "In our time, Mom never died. You started dating almost exactly today, give or take a few weeks."

"But…" Tony began, confused. Eventually, he decided to ask the first thing that came to his mind. "Why would we have started dating? Gibbs wouldn't let us, you know."

Stefan looked confused. "What are you talking about, Papa?"

"Rule 12. Gibbs won't let co-workers date."

Stefan snorted and suppressed a laugh, and Maria, who had been listening to the conversation burst out in gales of childish laughter. Tony wondered how what he had said was so funny.

"Maybe it didn't happen in this timeline," Stefan mused.

Tony gave him a questioning look. Stefan elaborated. "Uncle Jethro and Aunt Abby had been dating in secret for a while and they had a secret wedding about a month ago. About a week ago, Abby was injured, you discovered it."

Tony didn't know which to be more shocked at. That Stefan was calling Gibbs 'Uncle Jethro' or that he and Abby, of all people, could possibly be married at this very moment.

Stefan grinned at his father's reaction. "Papa, can we go down to the hardware store?"

Tony was still getting used to being called Papa, and didn't react. Stefan slapped him on the back, which was as high as he could reach, or he would have gone for his head. "Papa, the hardware store. I need a few things before I can even think of trying to get the uninvented things."

"Gibbs and Abby?" Tony said.

Maria nodded "Uncl' Jethro e Aun' Abby amano."

Tony nodded, dumbstruck. "Hardware store…"

Stefan sighed. "I think he's in shock," he told Maria.

Maria nodded. Tony blinked. Stefan tried to think of a way to snap Tony out of it. Tony came to a revelation. "If we make the Time Machine we can save Kate."

It was more a statement than a question. Stefan nodded. Tony wasted no time in taking them to the closest hardware store.

After buying several yards of wire and other important tools, they went to a computer store and ordered a new computer for NCIS. They headed back. Sure enough, Abby was tearing her hair out because Fiorella had managed to pull her computer apart, not to mention some of her other high tech gadgets. Gibbs commanded that they all get back to work, while Stefan and Fiorella fiddled with the Time Machine.

The two spent the next four months fixing it, every day getting more and more stressed, and Tony getting more and more impatient. Stefan, Fiorella and Maria were living with Tony, and had so far managed to escape the interest of child services, but they were worried that this would not last much longer. The main problem with the Time Machine was that it was very expensive to build and anything that hadn't individually been invented before 2006 had disappeared in the transition. Stefan worked on getting these things, shamelessly spending Tony's money like water on the project. He bought chemicals and metals and moulded them together using highly specialised tools. But by the end of the four months, they had created a Time Machine that would allow anyone who they keyed in to travel up to fifteen years forward or backward, as long as there were only three people at one time.

They were all surprised when Gibbs insisted that before they go home, they accompany him on a mission to save Kate from her death. They decided, eventually, that Gibbs, McGee and Fiorella would go. Gibbs, so he could explain it to his past self, McGee because of his computer knowledge, and Fiorella because she knew the most about how to work and program the Time Machine, whereas Stefan knew more of how to make it and its components. They had improved on it greatly – it now had more advanced security features to actually go, features much like the one that would allow you to reprogram it.

"Okay, Uncle Jethro, you put your hand here – no, here – that's right. Uncle Tim you put yours here, good. Okay. Activate verbal command to travel."

"Please state your full names and dates of birth."

The three quickly recited the details. "Commence travel?"

"Affirmative."

There was a flash and the three vanished from the middle of the bullpen.

Fiorella was prepared for the sensation, but Gibbs and McGee weren't. "What the hell was that for, Ella?" he asked, groaning as they appeared in the past, on the day of what would be Kate's death if they couldn't fix it.

"Sorry, Uncle Jethro," she said.

McGee, who had been bent over double straightened, noticing the eerie silence that was in the bullpen. "Ah, boss,"

"What, McGee?"

"It worked."

Fiorella looked at him as if to say 'duh'. "Did you think it wouldn't, Uncle Tim?"

McGee was silent. Fiorella looked around, seeing the completely befuddled looks of those who were in their rightful time – which was just about the whole office. Gibbs Jr and McGee Jr were looking especially dumbstruck. "Perfect! Not even a minute off!" she smiled. "So this isn't a useless piece of million dollar junk after all."

Authors Notes: Sorry, couldn't resist that little bit about Gibbs and Abby. Ignore it if you want. Not my favourite chapter, but oh well. Concrit appreciated, please review, got to go, bye
