The geek in me demanded to make this happen.

And I can't refuse anything to my inner geek ;)

"So! Where to next, Sexy?" exclaimed The Doctor as he spun around his beloved TARDIS console, feeling in an especially good mood.

He had after all just managed to rescue two different civilizations, prevented Gandhi from being turned into a turtle, and invented a new way to fry churros.

The wibbly lever sprung up on its own, and the main column started to shift. Lights flickered around the orange and silver console as the sound of time traveling grew louder. The Doctor smiled, holding tight with one hand while straightening his bowtie with the other, shoes sliding on the glass floor.

"Oooh, where are you taking me now?"

He edged closer to the screen, but then decided to make it a surprise and scrunched his eyes shut, preparing for landing with a grin.

"Geronimo…"

A little bit to the West of the New York Bay. SHIELD Helicarrier deck.

11:00, Monday, March 2013.

"Really, Fury? You couldn't have called for a meeting earlier in the morning, could you?" groaned Tony, wincing at the sound of his own voice.

"Quit complaining, Stark. Though I'm glad to see you actually came to this meeting, and on time." Answered Fury, shifting through the stack of paper in his hands.

"Pepper made me…"whined the inventor.

"You should give her a raise", said Natasha absently.

"The Lady of Pots is certainly a force to be reckoned with", nodded Thor. The other Avengers acquiesced silently in their seats.

"What did you even do last night anyway? I thought you said you weren't going out." Said Bruce, leaning towards his friend to pat him on the shoulder.

"An artist's mind is fickle…and man those twins were hot. Besides, Captain Spangles was my chaperone."

"Which is the only reason you're actually able enough to attend this meeting", admonished Steve with a frown.

"Hey, how come you never invited me as chaperone?" pouted Clint.

"Because you'd be a rubbish chaperone, you'd just go along with him. Whereas I can't get drunk", said Steve, at the same time as Tony quipped: "Because I enjoy way too much embarrassing Mister Virginity 2013".

"Could we get back to the original reason for this meeting?" growled Fury, putting both hands on the table and staring at each member of his team.

But just as he finished his sentence, Clint sat up straight in his seat, eyes wide.

"Eager, are we Katniss?" said Tony, raising an eyebrow at the archer.

"Shut up, Stark. Can't you hear it?"

"Hear wha-"

vworp vworp vwORP vWORP VWORP

The Avengers exchanged confused glances and raised eyebrows at the bizarre sound, then blinked collectively as a shimmering shape appeared barely a few meters next to them.

Natasha was the quickest to take out her gun, aiming it at the apparition without a second hesitation.

Thor and Steve reached for their weapons while Clint cocked an arrow.

Good thing all of them had their equipment on. Well, almost all.

Tony checked his bracelets gingerly, and edged his seat closer to Bruce, who sighed.

Fury took out his own gun, barking quick orders into his headset.

As they took their positions, the apparition slowly took the shape of a blue box, headlight shining bright and casting golden shadows on the deck.

The agents stopped working completely to stare at the strange phenomenon, most of them too puzzled to even reach for their handguns.

The wooden door suddenly creaked open, making everyone tense up.

"Blimey, what a landing! Must have been quite the moving target!" exclaimed The Doctor, coming out backwards from the TARDIS, coughing out a bit of smoke.

Fury and The Avengers took in the appearance of the newcomer with varying degrees of disbelief.

The stranger was sporting a dark purple coat, some slightly too-short black pants, and short dark boots. His brown hair was in disarray, flopping gracefully over his forehead.

And he was wearing-…was that a fez?

"Who are you and what are you doing here?!" shouted Fury.

The Doctor flipped around with a squeak, plastering himself against the box. He hesitated a little, hands waving around, before putting them up in the universal non-threatening message. Taking in the various raised weapons with a gulp, The Doctor's gaze suddenly stopped on Steve's blue and red shield.

His eyes lit up instantly in recognition and he grinned, taking in his surroundings with a newfound awe.

He knew exactly where he was.

"The Helicarrier! Sexy, you've outdone yourself!", he exclaimed loudly, still disbelieving.

"And you must be Captain America!" He pointed, fear forgotten. "I've always wanted to meet you! Blimey, that serum worked quite well didn't it? If I hadn't been there to see the transformation I would have thought it was Timelord technology!" Steve blinked, bewildered.

He turned to Tony with a flourish: "Your father was very proud. Though I'd rather talk about your breakthroughs! Oh, and congrats on that promotion! Who would have thought you'd be be such a fantastic dir-…", he trailed off at Tony's frown.

"Wait… Sorry, what year is this?"

"March 2013, why? And what's that about a promotion?" answered Tony, eyes narrowed. Bruce also had a very puzzled look.

The Doctor slapped his head.

"Right! Sorry, too early, forget I even mentioned that. Time travelling tends to scramble your brain a little. A bit like an omelette. Fines herbes! Except not really. Ignore the omelette." The strange speech was punctuated by great flapping of hands.

He turned towards Thor just as Fury was about to open his mouth.

"Thor! God of Thunder and bearer of Mjolnir! I finally get to see you, I've heard so much about your exploits from dear Frigga!"

Thor startled, just as the other Avengers looked at each other, increasingly confused.

"My mother, you say? She has not mentioned any like you. Are you a mage, to travel so between the realms?"

"Me? No, not exactly, no. Well, maybe sometimes. But seriously though, Asgard is quite a though place to reach! Really got to get the time right. Now, about your mum you know, you should go visit her more often. She might have threatened to come pick you up herself. Charming woman though, very smart. Great skills with a knife. She taught me a few moves. That, and her bilgsnipe soup recipe. "

At this point Thor had completely lowered his hammer and was frowning with his whole face.

"Fascinating place, Asgard." The Doctor continued, "You two would probably go crazy over the physics though." He said, pointing at Tony and Bruce with both hands, "I know I did. Seriously, what is it with that bridge?"

"Okay, enough!" cried Fury, banging his hand against the table. "Who are you and what are you doing here?"

"I'm The Doctor."

"Doctor What?"

"Doctor WHO. You gotta ask the question right, Nicholas. But that is my name, The Doctor. And to answer your second question, well, I honestly have no idea. Having fun and helping around, most probably. Oh, and running, of course. That's why I have these boots. Very handy. For boots, you know."

"Hang on, are you a time-traveller then? Because the way you talk-", asked Clint.

"Ah, yes, I am actually. Sorry about the timey-wimey confusion, I always get mixed up with dates. Ask my wife. Or anyone who's ever met me, really."

"So…time travel is real?" asked Steve, edging closer.

"Yes, it is. Though I'm sorry Captain, but your crash is a fixed point in time, couldn't alter it. A certain Peggy asked me to pass on a message though, hang on, I'm sure I've got it somewhere." He added, ruffling frenetically through his pockets, smiling softly when he saw Steve's eyes widening at the sight of a crumpled letter.

"That's her writing alright…"the soldier murmured, not quite believing his own eyes.

The Doctor grinned, then turned to Fury.

"If you need any proof that I'm really very not a threat, just contact Kate Lethbridge-Stuart, from UNIT. She'll vouch for anything I do. Well, mostly anything. In my defense, that giant wombat had it coming."

"UNIT, then? Fine, I'll make the call", said Fury, still suspicious. But the man had earned himself at least a few minutes to prove her wasn't a danger.

A few minutes and some harsh questioning later, he was freed from all suspicion. Everyone still regarded him a little oddly though, and The Doctor vaguely heard Fury mumble something about "those goddamn secretive Brits…"

He proceeded to spin around towards Tony and Bruce to place his arms around their shoulders.

"Now then, how about a tour in the Stark Tower lab? I've got some fascinating theories I'd like to discuss with you two…

Oh, and did I tell you Doctor Banner? I just love the way you transform into that Hulk fellow. Fascinating stuff. See, I've also got this friend called Jack who was humanoid and all until…"

His words died out as the trio made its way towards the lab.

Fury massaged his temples.

This was going to be a long day…

Ta-Daah!
