Disclaimer: I own none of the characters below (unfortunate, I know) They belong to either the BBC or CBS

My first crossover and it's Torchwood/NCIS, and after writing this, I now have the greatest respect for people who write crossovers. It is quite hard at times to keep the characters in character and not go mixing it up with other characters.... if that makes sense. I'd just like to thank BabyBoomBoom0029 who offered to Beta read this, she did a wonderful job. :) Also, Lys - all Tiva in this is for you. Whether it's blatantly obvious or just your imagination. it's for you! :D

Enjoy!

Chapter One

The Torchwood Hub

It was almost peaceful inside the Hub, before Jack burst out of his office.

"I've just been told about an alleged Weevil attack."

"What?" Tosh's eyebrows immediately shot up into her hairline. "There was nothing on the scans." She turned back to her computer screen to check.

"That's because it's not in Cardiff and it wouldn't register on the Rift Monitor." Jack replied.

"Where?" Gwen asked, as Owen emerged from the autopsy room, his arms folded across his chest.

"Middle of the North Atlantic Ocean."

"What?!" Tosh and Gwen exclaimed in unison.

"Flipping hell, Jack. April Fool's was weeks ago!" Owen said.

"I know and this isn't a joke." Jack managed to keep a straight face for a few minutes until it dawned on everyone else that he was actually tell the truth.

"You're serious, aren't you?" Tosh stated.

"I'll start the packing, then." Ianto said with a grim smile.

"Hold on, Ianto." Gwen interrupted. "We can't just go marching off. I have a wedding to plan, not to mention Owen has only just recovered."

"You can't recover from death, Gwen." Owen stated matter-of-factly.

"That's beside the point. I can't just pack up and leave because we happen to have a stupid weevil running amuck on the other side of the globe. It's not our responsibility, Jack! UNIT can handle it!"

"Calm down!" Owen said, holding out his hands as though he were dealing with a very skittish wild horse. "Sometimes, I swear PMS lasts all month long." He muttered under his breath, as an afterthought.

"And it's not bloody PMS, Owen Harper!" Gwen, having obviously heard, shouted in reply. "It's you!"

"I was only joking." Owen replied, giving a crooked grin.

Gwen continued to glare at him, as Jack spoke again. "I'm sorry Gwen, but we have to go. We've actually been requested."

"Us? Requested?" Gwen forgot her anger at Owen.

"Don't tell me it's the CIA. They have no understanding of reporting, or filing for that matter, whether it concerns aliens or not." Ianto groaned.

"No, actually." Jack replied, and he could have sworn Ianto gave a visible sigh of relief. "Some organisation called NCIS."

"Is that like CSI?" Owen asked.

"Well that's what I originally thought, but the lady on the other end, Jenny I think her name was, said explicitly that they were nothing like CSI, then made some comment about Dyslexia." Jack replied, with a slight frown.

"NCIS - Naval Criminal Investigatory Service." Ianto said without a beat.

"Typical teaboy, knowing everything." Owen muttered.

"Naval?" Gwen said a tone of curiosity in her voice.

"Yes, they deal with crimes involving Navy officers, I believe." Ianto continued.

"Naval." Jack said, his eye glazing over. "You mean like young men in uniforms, running around on ships, always wearing their Navy caps and forever referring to you as a superior."

"Jack." Ianto warned, as the rest of the team rolled their eyes.

"Sorry." Jack replied, flashing his trademark grin and Ianto shook his head.

"So a Naval officer was attacked by a Weevil." Tosh confirmed.

"In the middle of the North Atlantic Ocean." Owen continued.

"Yep." Jack was still grinning.

"How did it get out there in the first place?" Ianto questioned.

"That's what we're off to find out." Jack said. "Torchwood is going to sea!"

NCIS - the 'Bullpen'

Tony glanced up from his magazine to glare at the pile of paperwork. He could have sworn it had grown in the past hour.

"You've not going to get it done by staring at it." Ziva pointed out, with a smirk.

"Thanks for that Zee-vah." Tony replied with a glare, "Where's all your paperwork?"

"It's done."

"You're kidding!"

"I'm not. McGee has done his too." She stated, continuing to smile at Tony's annoyance.

"Where is Mr. Elflord this morning anyway?" Tony grumbled, glancing at McGee's empty desk and directing the conversation away from paperwork.

"I'm here; wondering why looking at pictures of semi-naked women is helping with your paperwork." McGee said, from behind Tony's shoulder.

Tony gave a yell of surprise and fell out of his chair and onto the floor. As he struggled to get up again, Ziva laughed and McGee walked around to his own desk, a smug smile on his face.

"What have I told you about sneaking up on me, Probie!?" Tony warned.

"Nothing. You've only said that to Ziva and Gibbs." McGee pointed out, instantly.

"Good point, McGee." Gibbs walked in, apparently out of nowhere. "DiNozzo, get up off the ground and gear up."

"We've got a case, boss?" Tony asked, scrambling to his feet in excitement; he was glad to get out of his paperwork.

"Yep." Gibbs replied, making straight for his desk, and taking his gun out of it, and Tony punched the air in joy.

"What is it, Gibbs?" Ziva asked, slinging her backpack across her shoulder.

"Petty Officer killed in suspicious circumstances on board a navy ship."

"This ship got a name, boss?" McGee asked, as they made their way to the elevator.

"Not that we know of." Gibbs said, irritated.

"They're not telling us." Tony guessed and Gibbs gave a nod in answer.

"I hate it when they do that."

"Me too. We'll be catching a plane out in two hours time. You guys go ahead." Gibbs stopped outside the elevator. "Gotta call Ducky up, him and Palmer are coming with us."

"And Abby?" McGee asked.

"She stays here, McGee. We'll need her lab, preferably with her in it."Gibbs glimpsed McGee nod, somewhat disappointedly, before the elevator doors closed with a ping. Walking away he pulled out his mobile and dialled Autopsy, knowing Ducky would already be down there.

"Jethro, hello!" The medic answered.

"Hey Duck, need you on this case we've got." Gibbs responded, getting to the point.

"What do you want me to do?" Ducky asked with a slight sigh.

"Come with us to a navy ship to do an autopsy." Gibbs answered simply as though he was asking him to join him for coffee.

"I see. Well I suppose if it's necessary."

"It will be. We can't have another unknown organisation taking control of the autopsy." Gibbs said with a grin.

"An unknown organisation?"

"Definitely unknown. Jenny sent for them especially, and the only thing I can make out is that they're from the UK."

"Really, sounds interesting. I am presuming you have told the rest of the team about this."

"Not yet. I can fill them in on the way."

"Ok, I'll be down with the garage with Jimmy in a moment."

"Good to hear, Duck."

"It is good to hear. Finally, some people that may actually appreciate my stories from when I was in Scotland. Of course, the English and the Scots haven't always got along. I remember this one time-"

"Duck." Gibbs interrupted him.

"Oh sorry, Jethro."

"They're not English or Scottish, Duck."

"Don't tell me their Irish. Or even worse-"

"They're Welsh." There was a pause, "I'll see you soon, Duck and thanks." Gibbs snapped his phone shut, smiling, imagining the medic's reaction.

This was going to be interesting.
