OOOO

It was a normal evening at the Shield Orphanage. Natasha and Clint were nowhere to be seen, but if you asked anyone they'd tell you that they're probably practicing their spying skills, because that's their favorite game. Pepper was in her room doing her homework and the additional work she had asked her teachers to give her, because she wanted to be the best. Bucky was watching Steve, the only adult of the orphanage, cook diner. Those two were truly inseparable, Bucky followed Steve everywhere he went, and the caretaker truly didn't mind.

Loki was quietly rereading one of the few books of the Orphanage when someone knocked on the door.

Now, that was unusual. No one ever came to the Shield Orphanage.

"Steve ! Someone just knocked on the door !"

There was a short silence, and Loki knew it wasn't because Steve hadn't heard, but simply because no one had ever knocked on that door. The only people who ever visited the Orphanage had a key.

"Go open it ! I'm coming in two minutes !"

Loki sighed and closed his book, making sure to mark the page with one of his drawings.

Seriously it wasn't fair, he wanted to just do everything he wants today because it was his birthday, and okay he had done everything in order for everyone to forget it because he didn't want people to feel forced to give him something. He knew they didn't like him, having them giving him something with a fake smile would make him feel like he's going to throw up.

The someone behind the door knocked again.

"I'm coming !" Retorted Loki, annoyed. Couldn't this mystery knocker wait two seconds ? Seriously, he was ready to bet this was another of those stupid adults who never listen to what kids have to say.

He opened the door with a scowl on his face and glared at the stranger. However as soon as Loki recognized him, his eyes widened and he called Steve again.

"Steve ! Tony Stark is at the door !"

OOOO

Tony followed the little blond thief for hours, wondering how the hell this kid hadn't noticed him yet. Seriously, the boy never looked around once. He wasn't a really good thief, he was really lucky he hadn't stole from that bastard of Justin Hammer. This guy would have had him put in jail for sure.

The kid was having fun with Tony's money, buying a bunch of different books and toys and even… A few dresses and some perfume ? Well maybe he had a sister. Or weird tastes. The inventor wasn't judging though.

Lunch passed, and the kid didn't appear to be hungry since he didn't buy himself anything and just kept going through shops. Tony couldn't stop to buy something for himself either as he would instantly lose the kid. So he kept following him, and ignored his hunger.

Two hours later, the kid exited a toy store, a soccer ball under his arm and his old backpack even fuller than it had been before, and started walking towards the exterior of the city. Tony hesitated for a second, but then decided he had to talk with that kid parents about the proper education and care that any parent should give to a child.

The boy walked for at least three hours, and it's only when the sun was setting that the young thief threw his backpack and his ball on the other side of a wall before climbing over it.

The inventor waited for a minute to be sure that the boy wasn't trying to trick him, but he heard the sound of a door opening and closing, so no, that was where the thief lived. And that looked like a very big and very damaged home this kid has there. Parts of the roof were gone, and some windows were shattered. The shutters looked like they were white once, but now they were just grey, and sometimes they were missing.

Tony walked around the street and found the official entry. On the wall next to the opened rusty portal, was written :" Shield Orphanage."

So the young thief was an orphan, then.

Tony really shouldn't be feeling bad for a boy who didn't hesitate before stealing his wallet and phone.

But he was.

He didn't know if he really wanted to go in now. If the caretaker learned that the boy had stolen something, he might write it on the kid's file and then the boy would see his chances of getting adopted drop.

Yeah, he shouldn't go in.

Two minutes spent staring at the orphanage later, Tony sighed.

"Fuck it." He mumbled and walked towards the door before knocking four times.

He heard a young voice coming from inside, but no one went to open him, so he knocked again after a while.

A young raven haired boy opened the door and glared at him. He really didn't look happy with the fact that he had to open the door. However when the boy looked at his face his eyes widened and he called over his shoulder : "Steve ! Tony Stark is at the door !"

Tony heard something shatter in another room and he saw Loki put his hands over his ears and close his eyes tightly.

No knowing what to do, the genius crouched and put a hand over the boy's shoulder. It was the wrong thing to do apparently, because the kid instantly flinched and stepped back. As running steps could be heard coming their way.

"Loki ! I'm so sorry ! It's just the sound of a broken plate, you're here, you're alright, everything is alright."

Comforted the hottest guy Tony had ever seen as he entered the room.

The genius decided to let himself in and close the door behind him.

"Brother !" Shouted a familiar voice.

The blond thief came running down the stairs. Tony crossed his arms, ready to look as mad as he could even though all the anger had left him a long time ago, if there ever was any. The boy quickly noticed the man in the doorway, who was looking slightly angry, even if his eyes stated otherwise. The kid's face turned blank and then guilty afraid and ashamed as he recognized the man.

At that moment, a dirty blond kid walked down the stairs with a purple sweatshirt. And Tony Stark was pretty sure it was the one Thor had bought earlier with his money. The kid looked at Thor's scared face, then at Tony.

"Tell me that it's not Tony Stark's wallet that you stole…" He whispered to the other blond kid.

"That's exactly what he did." Stated Tony. He didn't really care though, it wasn't even a scratch on his bank account. He'd like his phone and wallet back though.

The raven haired kid whose name was apparently Loki facepalmed. "Worst. Brother. Ever."

OOOO

The way back home from the parc was quite long and they were left on their own, but Pietro and Wanda didn't mind. Their parents were way too busy to take them to town and even if they were just five years old, they understood that.

Their mom was probably cooking diner as their father was cutting wood. The sun has jud set and even though the western part of the sky was still on fire, the children could see the brightest stars starting to appear.

The night was going to be beautiful. It was a shame they weren't old enough to stay up and watch the stars. Their dad promised them to let them watch once they reached ten years old.

When they entered their home, they were greeted by the warm smell of their diner and the welcoming smile of their mother, who asked them about their day. Pietro was very happy to tell her everything about the games in the parc and school, but he chose not to tell her about the policeman. He wasn't sure if he had done something wrong or not, and he didn't want to risk not having dessert.

They ate and they played a card game next to the chimney and then they went to bed in their separate rooms. When they learned that they would be getting twins, their parents decided to make two separate rooms for each of their babies, in order to let them know that they truly were both special to them, and different from their twin.

Pietro was woken up in the middle of the night by a strange noise outside. And there was a light that definitely wasn't the moon lightening his house. He got up and tried to look outside the window, but the light blinded him. All he could make out was the figure of a man. The man waved at him.

A sudden wave of pure fear went through the boy and he ran to his sister's room as a huge noise, like a whistle, resounded through the garden and towards the house. Before Pietro knew it, an explosion had occurred in his parents' bedroom.

"WANDA !" He cried as he entered her bedroom and started pulling his sister out of her bed. They had to run away out of the house, and fast.

"PIETRO !" Panicked the little girl as another loud whistle made itself heard.

A weird metal thing went through the wall Illuminated by the blinding light and landed on Wanda's scarlet carpet.

Pietro barely knew how to read, but the letters were big and easy to decipher. 'STARK' and some other, smaller word, starting with an 'I' after.

"Come on ! We have to run !" He shouted to his sister and he pulled her out of her room. They ran downstairs and then out by the kitchen's door, which was on the opposite of the light.

As they ran away towards the woods, they heard a second explosion. Wanda stopped running and turned to see.

Their entire house was burning. The only home they had ever known. And their parents in it.

"Are mom and dad-" Asked Wanda. Pietro could hear it in her tone. She already knew.

"Yes."

A first sob escaped the girl's lips. And then another. Pietro took her hand and led her to a safe place into the woods, somewhere the agressive light couldn't reach. Then he put an arm around his sister's shoulders, and she instantly held onto him as if he was the only left that mattered for her.

His heart sank when he realized that he actually was.

He thought back of the weird policeman, and understood that it was his actions that had led to all of this.

"I am so sorry little sister. It is my fault. I am the worst brother ever."

Wanda just kept sobbing, unable to stop, as Pietro's eyes remained dry and empty of any emotion as he watched his childhood home burn, and his innocence with it.

OOOO
