Note: I didn't see Twilight, since I was on a plane, (and I wasn't going to miss going to New Zealand to watch TV) and my friends only have VCR taping, which is really annoying because Dad threw out our VCR… so I know it's on a tape just waiting for me to watch it, and I can't. Anyway; the point: details pertaining to Twilight are almost certainly incorrect. I was very vague for the purpose of disguising this.

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 Four: Complication

Gibbs Sr had been under the impression that they would be arriving before anyone was in the office, but Fiorella had seen fit to change the plans. What good would it be, after all, if they didn't even believe them?

Gibbs Jr suddenly broke the silence. "Who are you and where did you come from?"

Fiorella spoke for all of them. "The future. We're sorry, but we can't tell you any more than that… well, I guess it doesn't hurt to say he's U-Gibbs and he's McGee."

"Can you tell us what you're doing here?"

Fiorella shook her head. "Sorry."

Gibbs Sr decided to take over. "Look, all we need is to sort out a few things. When you go today, be extremely careful. I'll be coming with you, as will, um,"

He paused an whispered something to Fiorella.

"Angela and Tim. Angela has designed these, well, devices which you will all wear at all times?"

"What do they do, boss?" Tony asked. Gibbs Jr glared at him. Gibbs Sr laughed internally at his younger self.

"They might save your life, DiNozzo. You did bring the remote control, didn't you El-Angela?"

Fiorella nodded. "Sure thing, Gibbs."

Gibbs Sr, McGee Sr and Fiorella mainly kept to the shadows. Then the first bullet hit Kate in the chest.

"Are you okay, Kate?" Tony asked with concern. Kate nodded.

"I'll be fine." She said shortly, as Tony helped her up. Suddenly she felt excruciating pain as an electric shock ran through her body, making her jolt suddenly to the right. They heard a bullet crash into the car behind them, not millimetres from Kate's head. Tony had apparently felt a shock too, and had also jolted out of the way of the bullet.

"Holy shit, Kate, that was close!" Kate nodded, wide eyed. McGee Sr and Gibbs Sr suddenly burst out from the sides, firing their guns where Tony and Kate couldn't see. Fiorella grabbed the disc that was the Time Machine, snatched Tony's gun, and pressed a button. She was suddenly standing behind Ari, her gun on his head.

"Don't move," she said dangerously.

Ari tried to wrestle her off, but a click of another button saw McGee Sr and Gibbs Sr on the roof beside her, their guns also trained on his head. Gibbs gave the signal and McGee and Fiorella snatched their guns back and jumped back, while Gibbs put a bullet through Ari's head, as they had planned. Fiorella smiled. NO more weird Ziva chick flirting with Papa, Mom alive. Mission accomplished.

"These teleportation cubes are fantastic," McGee commented.

Fiorella nodded. "Yeah, they were really good for this too. But they won't be invented for another decade and a bit, and even then they're as expensive as hell. And no, I cannot speed up the process," she told him, anticipating his question. "But I will let you keep one set, if you promise not to see how it works. That could, theoretically, bring about the apocalypse. And we should really get back to where Mom and Tony are. There's a chance that Ari might have fired another bullet before we got to him. I did set the shockers to every second, so it won't have hit them, but they might be injured."

Gibbs, McGee and Fiorella teleported back to where they had been only moments before. Fiorella had been right. A bullet had grazed Kate's neck, and she was bleeding profusely, and they could hear an ambulance wailing in the distance. Tony confronted them.

"I thought you said you were going to keep us all safe! But instead you electric shock us and allow Katie to get hurt!"

Gibbs Sr sighed. "If she hadn't got the first electric shock, the bullet would have hit her dead centre of the forehead. She would have died instantly. At least she has a chance this way, DiNozzo."

Tony seemed to reflect for a minute. "I guess. Uh… thanks, then."

Gibbs Sr smiled. He finally felt free of Ari, and revenge for Kate had been extracted. "We're done here, Angela," he said, and Fiorella nodded. Moving slightly to the side so that Tony couldn't ear what they were saying, and they all placed their hands in the correct positions, went through the correct motions and flashed out of sight.

Tony shook his head in amazement as he saw them disappear, thinking to himself that if he had a time machine it would be a great way to impress the ladies.

Meanwhile, Gibbs, Fiorella and McGee were travelling through time. This time they'd all been prepared for the sensation and managed to hold themselves together. Fiorella looked around carefully. She breathed a sigh of relief when she saw that Kate was at her desk, and Maria was sitting on her lap. She wasn't quite sure how everything would work out though, after all, most time travel theory she'd read described an eternal loop that thw world would be stuck in if a situation like this happened. She could only hope.

"Did it work?" Stefan asked.

Fiorella laughed, forgetting to worry about the loop momentarily as she looked at Kate. "Yes, Stefan! Yes!" He broke out in a wide grin.

"Fantastic."

Minutes later, Fiorella was wondering to herself about why Stefan even had to ask if it worked after all, he could see Kate himself, could he not? Shaking her head, she mentally noted to herself that she'd have to ask him later, when they were in private/ Like she had promised, she gave McGee a teleportation cube, making him promise not to tell anyone, and said goodbye to everyone. She and Stefan looked at each other. .

"I guess we'd better get home then," he said. "Maria, come on," Maria came up obediently. Stefan held out the disc, and Maria grasped it. Fiorella gave the command and they were back in 2020, in Abby's lab.

"You're back already," said Abby. "How'd it go? Where'd you go? What happened?"

Stefan smiled, glad to be back home, even if they hadn't discovered what they had gone for, how to get their parents to stop fighting. "It went well, Aunt Abby. We went a couple of years back, and nothing worth mentioning happened."

Abby seemed to accept this. Stefan was glad. When they were alone again, he confided that he thought that their memories had somehow become distorted, and the path in which there was no interference sort of took over, even though he had no idea how. He also explained that according to him, they'd gone back, no-one had figured out their identity, but Gibbs and McGee had gone back with her because they had insisted that they needed to do something. Stefan had only a vague feeling of urgency and a mission being completed.

"Weird," she muttered, and looked at the disc. "Stefan, I think I've learnt my lesson."

"What do you mean, it worked perfectly."

Fiorella shook her head. "I don't think you remember, that weird memory thing and all, but it wasn't good at all. Time is way too complicated and dangerous to be messing with, Stefan. I think that we should destroy this."

"But Fiorella, it's worth millions. Billions, even. Think of all the money we could make."

Fiorella shook her head. "You wanna know what I remember happening? We went to a world where Mom was killed, where everyone was a mess, Stefan. There was this weird Ziva girl flirting with Papa, and Papa was flirting back, and nothing was right."

Stefan looked horrified, but looked down at the disc he was clutching in his hands with the gaze of an adoring father. "I still don't think we should destroy it."

"No, maybe not," Fiorella conceded, seeing that Stefan wouldn't give in. "But I don't think we should be using it to try and change something as big anymore.

Authors Notes: Just the epilogue to go now! Comments on any aspect of the story are welcome. Next update may not be until Sunday week, because I have father/daughter camp on Friday and I might not get time to do it at lunchtime Friday, though I will try.
