Hey guys! Sorry this took so long. I got a little carried away... This is rather happy for me! I'm thinking of doing a Christmas bonus chapter, very short. Let me know if you'd like that. It would be based off of what is going on at my house right now.

Me: My gingerbread house is obviously the best!

Dad: Nope. I won this bitches! Admit defeat now, and I'll spare you the extra humilation!

Me and my brother: "Never say, 'I won this bitches' again dad..."

Brother: Besides, mine is clearly the best.

Mom: I won because I grew you humans! *holds up arms in victory*

Me: You cannot use that argument for everything! Besides, yours is just a lumpy mess!

Dad: *grummbling* She uses it on me too...

AN ACTUAL CONVERSATION WITH MY FAMILY TODAY! Love them, but we're all a little insane. Wait... The voices are telling me to give you the story. OK! Enjoy!

XxXxxxxXxXxXxXxXxXxXxXxXxXx

The agents really should have known better than to think the Mischief Mongers were done with their pranks after the first day, so it really was their own fault their mouth's were stained red, like blood (the theme music from "Twilight" following them around was a bit much, but go big or go home, right?).

They had gone after the decaf coffee. They weren't assholes enough to jack with the actual liquid, but the people who drank decaf deserved it. Seriously.

Needless to say, it was a rather large surprise to find Maria Hill with a stained mouth later that morning (she claimed she picked the wrong dispenser).

People were more cautious after that, and discovered that the hazelnut creamer was tainted blue, and the muffins would dye mouths black. But after lunch, people were even more surprised to find their mouths dyed orange or green. The cafeteria workers were almost as fearless as Nick Fury himself, due to the fact that people have tried steal, prank, and eat the food early.

And to top that, the cafeteria workers had anger issues to rival the hulk. They were chef school rejects because of their anger toward people who put any criticism on their food, but good chefs all the same. The agents had never tried to touch to the food before it was served, save a idiotic few, so this was a first.

What was even more surprising about the whole thing, the chefs laughed it off! It had Fury stunned, and even more awed at these adolescent assassins. So far they had cracked their servers, dyed the decaf red without any of the highly trained operatives noticing, and mess with the food with the chefs not going nucular.

When he asked Wolf during their meeting that day, she had laughed and said; "You offered them a challenge, did you not? Those four have always been a little… Competitive."

Fury had no idea the Mischief Mongers had overheard his words the two days before, but deeply regretted saying them.

And just when they thought it was over, at exactly three o'clock, the speakers started playing club music, the lights lowered and changed colors, and fog and confetti started blowing out of the vents. It looked like a nightclub on the helicarrier.

People soon saw the random articles of clothing lying on their desks. Oversized sunglasses, sparkly items, high heels, and revealing shirts and pants, things people would wear when going clubbing.

It took all of ten minutes for people to get into it. Even Hill and Natasha got dancing. The Mongers showed up in the main control room after about half an hour, wearing more modern clothes, rather than their normal assassin attire.

They each wore black ripped jeans, and the boys wore black combat boots, while Riley wore a high heel version of them. They each had on bronze bracelets up their arms, and their necklaces on display on their chests. They each wore low-cut ripped tank tops of their choice color, and wore a simple plain white mask.

They danced over to Clint and Natasha, who were jumping up and down to the music, and joined them.

"GUESSING YOU DID THIS THE SAME WAY?" Natasha yelled over the music to the Mongers, who flashed her grins.

"THE MUSIC AND THE LIGHTS, YEAH." Jace responded in the same fasion.

"BUT WE NEEDED SOMETHING TO MAKE THE FOG!" Evan called, pointing towards Tony.

"OUR RESIDENT GENIUS TOOK CARE OF THE MACHINES!" Riley whooped, spinning around in the crowed.

"AND OUR RESIDENT FEMALE MADE THE CHEMICALS FOR THE FOG!" Tony finished.

It took almost three hours for people to start calming down, and Shield was finally allowed back onto their servers.

Fury collapsed in his chair, grabbing a glass of vodka he had stolen from agent Romanoff's stash (she always got the strong stuff), and took a long drink, rubbing his hairless head.

He could only hope tomorrow would be calmer.

XxXxXxXxXxXxXxXxXxXxXx

Tony was starting to get a little cabin fever. Sure, he stayed at the den for months at a time, but there he was free to roam the French countryside, and now that he was a full assassin he could visit the city any time he wanted.

So, he got bored. And that, like we have learned so far children, is a very bad thing.

Even though he was a high profile asset, he didn't have very high level clearance. He had tried to get into several of the labs with the ID he had been given, but the little annoying voice had told him he had been denied access. That only made him more determined to get in. He spent two days searching (really a lazy look here and there) for an entrance, and finally he found it.

The air vents were flawed in the plan built for the aircraft, as they were large enough to fit a fully grown man, much less a few teenagers. They had packed supplies (they planned to stay in the vents dropping things all day afterwards anyways), and took off the cover to the vent in their room.

Tony went in first, hoisting himself up into the air duct, and scooching forwards to make room for Riley, who followed gracefully. Evan came next, and Jace took up the rear, pulling the vent closed behind them to cover their exit point.

It was a long way around, army crawling forward, but soon Jace realized they could crawl on their hands and knees, so they did. Their progress was much faster after that, and they quickly found themselves at what could only be described as an intersection of sorts for the air ducts.

There were many vents leading different directions off into the helicarrier, around six or seven tall, and eight or nine around, making a tall octagon of sorts for them to stand in. The Mischief Monger stretched, tugging the knots out of their stiff muscles.

"Ok, labs are this direction, want to keep moving, or wait until the afternoon to head in there?" Tony asked, looking at his clan.

"I think we should wait until around lunch to get into the labs, less chance of getting caught." Jace spoke up, rolling his shoulders.

"Yeah, and it's mean to ruin people's day's so late into it." Riley chirped from her corner, where she was looking down the different air ducts, trying to guess which one would lead to Fury's office.

"Besides, then we can steal things from the lab and move them random places so people think they're losing their minds." Evan sniggered.

"Alright, got the coms in?" Tony asked, receiving nods in return. "Map out your surroundings so we can get a good mental image of the place, and record you findings. Try to aim for the agents with a stick up their ass, remember?"

"Got it Tone,we're good. Let's get this party started!" Riley cheered, swinging herself into the nearest duct, leading west.

Jace took a duct leading east, Tony took one leading south, and Evan crawled into one headed north.

Tony crawled forward, occasionally looking down through the vents at the agents below, making the offhanded comment or two over the coms. He finally spotted the perfect target. A man by the name of agent Ferish. A stiff, uptight man, on everybody's ass about things they didn't deserve. Tony pulled out a balloon filled with a substance Riley had concocted (the MM didn't bother asking what it was). It itched for almost six days, would dye them hot pink for three, and had the smell of rotten eggs until they took a shower.

Tony lined up his shot, waited, and then dropped it. It splattered on the man, just missing the nearest agent to him, and let out a squawk of surprise when it made contact. A small note fell to the floor, and Ferish picked it up, letting out a growl of anger, before stomping away to rinse off.

The note had read: "Should have gotten that stick removed (I know a guy)!"

Tony snickered, and moved on to the next vent, looking out for others with pink dye to see who his siblings got, every so often dropping one of his own. Once, he heard a cackling coming from down the east side, and watched in amusement as a woman (who had insulted them without knowing they heard the day before) sludged past, seething with anger.

She marched up to a door, and Tony realized with a start that it was the head agent for this quarter of the helicarrier. She knocked loudly three times, and waited, arms crossed, tapping her foot quickly with rage. The man finally opened the door, looking dejected at the thought of dealing the the prune of a woman once more, before holding back a laugh at the sight of her.

"Agent Herman. What a surprise." He said dryly, and a few people nearby snorted, but Herman took no notice.

"There are hooligans upon the helicarrier! I demand that they be punished for what they are doing this instant!" Tony thought for a moment of Umbridge from Harry Potter, before readying a balloon.

"And which agent is causing the disruption?" The head agent, who Tony noted was named Grimal, stated flatly.

"Not an agent! Those horrible children who call themselves assassins!" People around them laughed looking around for the Mischief Mongers.

"I'm sorry, but they are not under my jurisdiction. Please report it to deputy director Hill, and have a wonderful day." Grimal said flatly, flicking the door shut in her face. Herman started, and growled pacing off.

Tony whistled, like he was calling a dog, and she turned with a red face to yell, only to find no one there for her to scream at.

"Here bitchy, bitchy, bitchy!" Tony called from his vent. Herman's face went from red to purple with rage.

"Just FYI," Evan taunted from a vent a few feet down, causing her to spin in his direction.

"We don't just call ourselves assassins," Jace called.

"We are assassins." Riley finished up their little statement.

"And if you don't start singing a different tune, asshat," Jace hissed.

"You might be added to our list of kills." Tony spat, and as if on cue, they threw two balloons each at agent Herman, and she was sticky with the magical pink itchy powder/dye.

For good measure, a few agents 'accidently' spilled their waters, which caused the dye to stain for longer. They were instantly in the MMs good books. They each cackled at Herman's shriek of rage and surprise, and they crawled away, giving praise to each other through the coms.

They fell silent for a little while, and eventually Tony realized he was getting close to another 'intersection', as he was now calling them, so he could stretch.

What he wasn't expecting, was to jump down and land on a pad of pillows and blankets.

With a start, he stood, looking around quickly. "What the hell…" Then he spotted Clint and Natasha, each with wide eyes.

Clint was fiddling with his knives, polishing them much like Riley did when she was relaxing, and Natasha was curled up reading a book, "The Fault in our Stars".

"How the hell did you find us?" Clint asked in shock, wide eyed. Natasha slowly put down her book.

"Ummm, it was an accident…" Tony mumbled, shuffling around slightly. At their questioning looks, he explained about the jitters they were getting, and how boredom is seldom good for others' health.

As proven when a rant still going from the Umbridge of the helicarrier echoed faintly through the vents from the east side. Clint laughed, and Natasha smirked.

"Feel free to hang out here if you like, just be decently quiet." Clint chuckled, and Tony took him up on that offer, calling the others, and the two assassins soon found themselves listening to the idle chatter of the young family.

"So, what do you guys have planned next?" Natasha asked, looking up from her book, which she had returned to not long ago.

The Mischief Mongers smirked, glancing at each other.

"A master never reveals their secrets…" They spoke as one in a mock mysterious voice.

"That's just creepy…" Clint muttered, watching them. The clan's smirks grew into large grins.

"What is, Clint?"

"Stop it!"

"What?" Natasha let out a quiet laugh as they continued tormenting Clint, who was getting increasingly creeped out from the innocent tone of all four voices combined.

XxXxXxXxXxXxXxXxXxXxXxXxX

Not too long after meeting up with Natasha and Clint, they scattered into the vent system once more, and met up at the previously planned rendezvous point.

"Ready, guys?" Tony asked, watching as the scientists and lab assistants left for their one hour long lunch break. His answer was Riley falling from the vent, landing in a soft crouch gracefully on the floor, before moving out of the way. All the while giggling gleefully.

After everyone had gotten themselves into the lab, they set to work. Tony quickly checked to make sure what they were working on wasn't vital to someone's life, before grabbing the glue, and sticking most of the office supplies to the ceiling.

Evan got to work switching out papers for fakes that looked like their notes had been ruined by water, before putting the real notes in a box… And gluing that to the ceiling as well.

Jace quickly went around, taking equipment up, and moving them all to opposite stations, and evan ran across the hall to other labs.

Riley cheerfully danced around with her usual finesse, painting things bright neon colors in a mixture of paint she had designed herself. It wouldn't interfere with biological nor synthetic results, or alter them in any way. Nothing they did was harmful to the work the scientists were doing.

Then, with ten minutes to spare, they crawled back into the vent after admiring their work, and removed themselves from the vent system in their room. They watched through the cameras (which Tony had hacked to alter the footage of them) as the surprised agents walked into the brightly colored, upside down, messy lab.

There were a few younger staff members that had burst into tears.

After laughing themselves nearly to tears, they got themselves ready for the final meeting with Fury.

xXxXxXxXxXxXxXxXxXx

While waiting for the pirate (cough, director), they got bored. This time, it didn't lead to mischief, as they were profoundly good at, but a song.

Tony began humming the tune, Jace picking up the harmony. Evan found the drum part, and tapped his fingers on the table, humming along another line of the song. Soon, Riley joined in with the lyrics.

"There was a time when I was alone

Nowhere to go and no place to call home

My only friend was the man in the moon

And even sometimes he would go away, too

Then one night, as I closed my eyes

I saw a shadow flying high

He came to me with the sweetest smile

Told me he wanted to talk for awhile

He said, "Peter Pan, that's what they call me

I promise that you'll never be lonely, " and ever since that day

I am a lost boy from Neverland

Usually hanging out with Peter Pan

And when we're bored we play in the woods

Always on the run from Captain Hook

"Run, run, lost boy, " they say to me

Away from all of reality

Neverland is home to lost boys like me

And lost boys like me are free

Neverland is home to lost boys like me

And lost boys like me are free

He sprinkled me in pixie dust and told me to believe

Believe in him and believe in me

Together we will fly away in a cloud of green

To your beautiful destiny

As we soared above the town that never loved me

I realized I finally had a family

Soon enough we reached Neverland

Peacefully my feet hit the sand

And ever since that day

I am a lost boy from Neverland

Usually hanging out with Peter Pan

And when we're bored we play in the woods

Always on the run from Captain Hook

"Run, run, lost boy, " they say to me

Away from all of reality

Neverland is home to lost boys like me

And lost boys like me are free

Neverland is home to lost boys like me

And lost boys like me are free

Peter Pan, Tinkerbell, Wendy Darling

Even Captain Hook, you are my perfect story book

Neverland, I love you so

You are now my home sweet home

Forever a lost boy at last

Peter Pan, Tinkerbell, Wendy Darling

Even Captain Hook, you are my perfect story book

Neverland, I love you so

You are now my home sweet home

Forever a lost boy at last

And for always I will say

I am a lost boy from Neverland

Usually hanging out with Peter Pan

And when we're bored we play in the woods

Always on the run from Captain Hook

"Run, run, lost boy, " they say to me

Away from all of reality

Neverland is home to lost boys like me

And lost boys like me are free

Neverland is home to lost boys like me

And lost boys like me are free" (Don't own "Lost Boys")

They finally noticed the gaggle of agents gaping in surprise at the Chasseurs, halting their tasks in favor of listening to the assassins sing.

"What?" Jace growled defensively. The agents quickly continued on their way, a few tripping in their haste to get away.

The four young family members had few outlets for their fear, anger, and overall pain of their lives. Music was their main one. They could pour emotion into the lyrics, and people could chock it up them getting into the song. But the Shield agents were trained to detect genuine and false emotions, and the raw sadness and happiness in the words pouring out of the girl's mouth were overwhelming.

Everyone pretended not to notice the tear in Fury's eye when he was standing outside of the doorway.

Hope you liked! Please review, I'll update faster. Also, let me know if you want that Christmas chapter. I need to know soon! Anyways, bye!
