A.N: I don't own the Avengers, Marvel and Disney do. Obviously. I only own the plot.

Natasha crept down the hallways, quite as ever. Usually Fury was asleep by now but you could never be too careful. Rumor was that a whole AI was programmed into his eye patch just to tell him when things were happening behind his back. It seemed silly, but she wasn't going to take any chances. From where Pepper and she slept to where the boys were, was two lefts, down the staircase and once to the right. It wasn't far for her to make at all. Easy peasy lemon squeezy.

Worried the stairs might squeak, Nat climbed onto the railing and slid down. Sliding on railings was a bit scary, (And even scarier in the darkness of the night.) because there's nothing to catch you if you fall, but that made it all the more thrilling to the third grader. When she reached the bottom, she softly jumped down, landing on the balls of her feet and made almost no noise at all. She quickly made way to Tony's room.

The door was already cracked open slightly. She slipped into the room with ease. Tony was sprawled out on his bed. Clint was in Tony's favourite hammock with one arm and leg hanging off the edge. He was snoring slightly. Always up high, Clint. It's not enough that your head's in the clouds, your body needs to be, too. Nat thought.

Bruce and Thor were in their sleeping bags on the floor at the foot of Tony's bed, and Steve was just to the side of them tangled in blankets. Loki was far off in the corner, propped up against the wall sleeping. He had a vice like grip on his Lego scepter and was muttering something. Most people looked peaceful when they slept; Loki looked like his cat just turned angry on him in the middle of a cuddle session. Natasha started walking towards him.

'gaAH' was something along the lines of what came out of her mouth a couple steps into the room. She looked around. No one seemed to have woken up. Good. Nat picked up whatever she had stepped on that had caused her so much pain. A Lego brick. These should be some sort of burglar security thingie. I wouldn't break into a house with these things everywhere. She then ignored her latest statement and continued to 'break in' to Tony's lego protected room. (Though, much more carefully.) She danced around the scattered toys until she reached her target.

"Loki." She gently whispered. Nothing happened. She pushed on his shoulder. "Loki, get up."

His head swayed a bit as he began to stir. "No, Thor. I don't want to get up. I'll get up when I want to." He said groggily.

Nat rolled her eyes. "No, it's me, Natasha. Now get up."

Loki didn't want to open his eyes. This was just a joke, wasn't it? Just another stupid prank his brother and Tony made up. But that did sound a lot like Natasha. He cracked open one eye and let it adjust in the dark. Then he opened the other one in shock that the best thing possible happened. It was truly Natasha! "Nat what are you doing here. You're a girl! This is the boys' room!"

"Shh. You'll wake the others." She whispered.

"Sorry." He whispered back. He looked at everyone else. Weird. Thor usually drools a bit when he sleeps. Loki noticed, then turned his attention back to the girl who had snuck into a room just for him. This stupid sleepover was turning out to be okay after all.

"Pepper and I need your help."

The first grader nodded enthusiastically.

"Can you help us get back at Clint for spying on us?"

Best. Sleepover. Ever. He had been waiting forever for this. Act innocent, Odenson, just like we've practiced. He nodded even more enthusiastically, his chin almost to his chest then tilting all the way back, but he did it more slowly. (That's how you make it look cool, not silly.) He paused after a few nods and thought over what she had said once more. He said the first thought that came to his mind. "Just Clint?"

"And maybe the rest of the boys too. We'll see. So you're in?" Nat held out her pinkie for him to shake. He took it with his and shook.

"I'm in."

They tip toed back to the girl's room. Loki still had his scepter in his hand.

The boys waited a minute until the 'company' had gone. Tony sat up slowly. Everyone else followed his lead, except Bruce. He got a pillow to the head for it.

"She took my baby brother!" Thor whisper yelled.

Clint whisper yelled back. "She ruined my," Tony glared. "…our plans!"

"Why was I hit with a pillow?" Bruce asked, rubbing the sleep from his eyes.

Tony quickly responded, "You fell asleep. You we're supposed to just pretend, Bruce." then turned back to Clint and Thor. "The girls have declared war."

Steve wanted to be a soldier when he grew up, but not now. He didn't like the idea of war with his friends. "Maybe Clint can just say he's sorry?"

Everyone went silent. Steve shrunk under everyone's eyes staring at him. "Or we can go into war?"

Clint hopped down from the hammock. "Tony? Where's the Nerf? I think she needs a taste of her own medicine."

Pepper heard the secret code being tapped out on the door. She let them in. "So Loki knows what's going on?" She said to the pair.

"We're going to destroy the others." Loki confirmed.

"Err. Sure. 'Destroy'" What did Natasha have to tell the kid to get him to join? "Why do you have a staff?"

Loki looked at his scepter and pouted at her choice of words. "It's not a staff! It is my battle scepter! "

Pepper and Natasha exchanged glances. They knew Loki wasn't a normal first grader. He was quiet and a lot of people made fun of him. But when your back was turned, he would pull the grandest of pranks. All the teachers called him the king of mischief. (A title Loki enjoyed tremendously.)That's why the girls wanted him on their side. He was a valuable ally. But a 'battle scepter'? That was a littler far off, even for the kid from the family that wore capes on occasion.

Loki then proudly added, "I made it myself."

"So anyway," Natasha redirected. "We need you to help us come up with something to do to them. A prank."

"Hmm." He sat down and thought. He had many things planned for Thor and his friends. But he was past whoopee cushions and handshake buzzers. He wanted to pull a prank they would remember. "Do you have any make up?"

A.N. I'm sorry. I feel like this was kind of short. Next chapter will be longer and hopefully up Saturday, but I want to make it really nice, not just throw it out there with a ton of errors, so if it is delayed until Sunday, I give you my word it will be longer and quality.

Thank you for taking the time to read this! I literally dance every time someone favorites, comments or subscribes to the story. I just hope my writing continues to be up to your expectation.

Also, a special thanks to BeanDipMcGee for the suggestion of make up as part of the girls' (And now Loki's.) prank. I can't wait to write that scene! (Though, I will have to learn the basics of make up now for accuracy. My mother will be so proud.)

That is all.
