A/N: I swear this story is my favorite thing right now. It is the only thing keeping me sane. (Well that and a few super special people who talk to me about this story and my headcanons. You know who you are!) Enjoy chapter 4!

We Must Celebrate

After breakfast was complete the avengers and co migrated into the living room. Tony was quick to put on Lilo and Stitch for background noise as everyone talked and bustled about. Wanda was immediately enthralled with the movie and sat cross legged in her SHIELD issued shorts and shirt in front of the television.

Pietro had quickly taken to Thor and was able to understand him and talk to him. The little boy was currently sitting in the God of Thunders lap listening to a tale about the Warrior Three and Lady Sif.

"It looks like they're adjusting." Clint sat down next to Natasha, looking between the two children.

"I just hope we can give them a kind of life they deserve to have. They deserve the best after all they went through." Natasha sighed as she leaned her head onto Clint's shoulder "I'm just not convinced that we can give them that. I mean how can I…" She took a stuttering breath "How can I ever be a good mother?" she pulled a face at the last word.

"You've already proven that you can, Tasha. You've calmed their fears and reassured them. You've held onto Wanda when she needs it. You're already good at this." He kissed her hair lightly.

Natasha smiled as she turned her head in order to kiss him gently "I'm going to go shopping with Pepper. Get them both clothing. I'll take Wanda with me. Pietro can stay here since Thor can interpret for him."

"Alright." Clint nodded his response "I think I should probably give Katie a call. Let her know so next time she comes she isn't surprised by them. Then I'll probably get our mission report done."

"Good luck with that." Natasha stood "Pepper still want to go shopping?"

Pepper grinned and nodded from her place next to Jane "Jane, Darcy, would you two like to come as well? We were going out to get clothing for the twins. As well as their other necessities." Both women nodded.

Natasha walked over to where Wanda sat entranced by the movie on the television and crouched down. "Wanda, I'm going to go shopping with Pepper, Jane, and Darcy. I would like it if you came with me. How does that sound?"

Wanda looked at Natasha and then over her shoulder at the other women and then at the movie on the TV. "I can watch it later?" She asked softly as she pointed to the television.

"Of course." Natasha smiled "I think you and Tony are going to get along well, little one. He loves his Disney movies and will love to watch all of them with you."

"You betcha!" Tony yelled from his position on the couch. He was halfway focused on the movie and halfway focused on the tablet in his hands and he had a large grin plastered across his face as he looked at Wanda. "We can have a movie marathon tomorrow if you would like that, squirt."

Wanda giggled as she stood up and nodded.

"All right then it is settled. Movie marathon tomorrow!" Tony let out a laugh of his own.

"Ok. Let's get going." Natasha reached a hand out and grabbed hold of Wanda's hand.

"Enjoy your shopping trip, ladies." Bruce said politely as the women and Wanda got into the elevator.

As the elevators closed, Clint got up off the sofa and began walking out of the room.

"Where're you headed, Katniss?" Tony said without looking away from the television.

"I gotta call Katie and tell her about the twins. I never know when she'll stop in or when she'll call wanting me to pick her up from her dads' apartment." Clint explained and then looked to Thor "You ok with him for a moment?"

Thor looked up and simply nodded before looking back to Pietro and continuing whatever story he had been telling.

Clint walked into the kitchen and pulled out his phone and dialed the speed dial for his protégé, Kate Bishop.

She answered on the third ring "Hey, Clint! Is there a mission?"

"Uh, no Kate." Clint rubbed the back of his neck

"Oh, ok. Then… what's up?" He could hear her laughing slightly.

"So… something happened on Nat and I's last mission…" Clint began but was quickly interrupted

"What did you do." She said flatly.

Clint scrunched his eyebrows together "Why's it have to be something I did?"

"Because it's ALWAYS something you did, Clinton." He could practically hear the girl rolling her eyes. "Plus I'm almost positive that Natasha is a being from another planet that can do no wrong."

"I think she would disagree with you." Clint let out a huff of a laugh

"Clint, get on with it." She said exasperated

"Oh, yea, right." Clint laughed "We adopted twins."

"WHAT?!" She yelled into the phone making Clint pull it away from his ear.

"OW." Clint began "We adopted twins. You know. Two kids? They're three. A boy and a girl. Pietro and Wanda."

"I don't know whether to congratulate you or call you an idiot." She was laughing again.

"Thank you?"

"But I cannot wait to be a big sister!" Kate's voice was filled with excitement

"Kate, you're not my kid." Clint rolled his eyes.

"Shut up, Clint." She responded playfully.

He laughed once again "Oh, and you should know, we rescued them from HYDRA. They were experiments. So they have powers. Don't be shocked by that when you come around them for the first time." Clint explained

Silence followed before Kate choked out an "I won't"

"Ok, can't stay on the phone, Katie. Got work to do. Talk to you soon. Bye." And with that he hung up the phone.

Meanwhile down in the parking garage

The four women had piled into the back of the large town car that Pepper had arranged to drive them around. Wanda sat happily on Natasha's lap.

"We'll need to buy some carseats. We don't drive often but it is often enough that they are necessary." Natasha sighed

"We'll get everything that you need." Pepper reassured her with a pat on the knee. "Let's do some clothes shopping first. It hurts me to see these cuties in these simple shirts and shorts from SHIELD."

Natasha laughed at that.

It did not take long for them to arrive at a small children's clothes boutique.

"Should we look for Wanda first since she's with us?" Darcy said as she began eyeing the little girls side of the store.

"That sounds fine." Natasha shrugged her shoulders.

"So, Wanda. What kind of clothing would you like to wear?" Darcy spoke softly as she looked at the little girl in Natasha's arms. "This place has lots of options. You can get a bit of each if you would like. And we can get lots of colors. What colors do you like?"

Wanda looked thoughtful "I want dresses. And skirts. I like red." She smiled.

"Ok, pretty girl. Red dresses and skirts coming up! Let's get shopping ladies." Darcy grinned.

6 hours and plenty of shopping later

"Thank you again for covering a lot of this, Pepper." Natasha said as she buckled a sleeping Wanda into her new carseat. "You really didn't need to do that. Clint and I would have managed."

"Exactly. You would've managed. Meaning you wouldn't've been able to get everything you did today. All the clothing. The furniture. The toys. The toiletries. You would've only been able to get basics. But now you have everything you need. Really Tony and I are happy to do this for you both." Pepper was smiling.

"Well, we appreciate it." Natasha smiled back "Now, we should get back to the tower and make sure the boys haven't completely destroyed the place."

"I'm sure they are fine." Jane waved her hand as she got into the car "They all seemed pretty preoccupied to get into too much trouble. I mean Thor was enthralled by Pietro."

"And Tony was busy trying to plan something for this evening." Pepper said.

"Clint was going to call Kate and then do the report from our mission." Natasha added in "And I heard Steve talking about meeting Sam Wilson for lunch."

"And Bruce never causes trouble." Pepper laughed.

"So everything should be fine." Darcy rolled her eyes.

Back at the tower

"Steve! You need to help me hang steamers!" Tony yelled at Steve as he came into the common room off the elevator with Sam Wilson.

"Tony, what the heck?" Steve yelled back "What's with all this?"

"I said we were celebrating tonight and I meant it! Legolas took the kid up to their floor for a nap about two hours ago. And I've been try to set up ever since. You gotta help!" Tony looked frazzled "Thor and Bruce went to pick up the cake and some snack foods."

Steve shook his head as he smiled and laughed "You're really something, Tony. Come on, Sam, we have a party to set up for."

Before they could get half of the decorations up the elevator opened and Jane, Darcy, and Pepper stepped out.

"Where is Nat and Wanda?" Steve asked as the women approached them.

"Oh, the kid was sleeping. Natasha wanted to take her to their floor to lie her down." Darcy said. "What's going on here?"

"We're setting up for a party!" Tony said happily.

"Now, Tony I hope you did not go too crazy." Pepper said in a chastising voice.

"Pepper, I swear, I didn't go overboard. Just going to be us here to celebrate the fact that now there are two munchkins in the tower to brighten the mood." Tony grinned "I just thought the kids would like the decorations."

"This is all very sweet of you, Tony." Jane smiled sweetly.

It was then that the elevator opened again and Thor and Bruce stepped out carrying bags of groceries as well as a large cake box.

"Where do you want all of this, Tony?" Bruce said as he walked into the kitchen.

"Could you get some bowls and such for the chips and dip?" Tony asked "And Thor just put the cake down by the stove and come here and help me get the last of these streamers up."

Everyone bustled about for the next forty five minutes setting up the common floor. Once everything was party ready everyone sat down on the couches.

"JARVIS? Can you please ask Agent Romanoff or Agent Barton if the twins are done napping? Please make sure to lower your volume when asking in case they are still asleep." Tony spoke to the ceiling.

"Right away, sir." The AI responded

There was only a moment of silence before the AI talked yet again saying "Agent Romanoff said that they will be down shortly."

When the elevator opened and the little family come onto the floor, everyone in the room was shocked at the change in the twins' appearance. The clothes was the most basic change. Wanda was wearing a red and black gingham dress that had a red belt and her hair was shiny and in a braid down her back. Pietro was wearing jeans and a bright blue shirt that sported a Captain America shield on it and his hair had obviously been trimmed.

No one was too surprised when Pietro immediately zipped over to Thor, immediately beginning to tell him in Sokovian about his new toys. What surprised everyone was when Wanda walked right up to Tony and tugged on his hand.

"What's up, squirt?" Tony crouched down to be eye-level with her

"Can we watch the movie?" She asked eyes wide.

Tony grinned "I think that can be arranged. Why don't you get a snack while I get JARVIS to play it for you?"

The little girl grinned wide before running to the table to grab one of the bowls of chips.

"JARVIS, you heard the little lady! We're watching Lilo and Stitch! Please, get it playing!" Tony spoke as he stood back up

"Right away sir."

"Tasha! Come watch!" Wanda called out from where she was now squirming around in one of the throws on the couch while Jane held her bowl of potato chips.

Natasha laughed as she walked over to the little girl. When she got to the couch she swooped the girl up into her arms and then grabbed the throw and wrapped it around the both of them before sitting on the couch with Wanda sitting comfortably in her lap.

"Clint! You too!" Wanda giggled as she looked at Clint still standing near the elevator.

Clint immediately crossed the room and sat down next to Natasha, wrapping an arm around her shoulders.

The chatter in the room died down as the movie began to play.

After the movie and cake

"We really cannot thank you all enough. Especially you, Tony. Helping us get everything they need." Clint spoke earnestly as he took a sleeping Pietro from Thor.

Natasha nodded as she shifted a sleeping Wanda in her arms. "And just being really accepting of this situation. We know it's going to take a while to get used to, hell, we aren't even used to the idea, so just thank you for being willing to work through it with us."

"There is no reason to thank us. We were just being supportive friends." Pepper replied softly

"Exactly. Plus, it is about time there is some rugrats in this tower to wreak some havoc." Tony grinned.

"It'll be nice to have them around. I like kids." Bruce said happily.

"Young Pietro is a marvel. I enjoyed spending time with him today and hope to spend more with him and possibly young Wanda as well." Thor said as quietly as he could

"They're great. And if either of you ever have any basic questions I do have younger siblings and cousins that I helped to raise." Darcy offered.

"Me too. Well the cousins part any ways." Jane added.

"It is nice to know you guys have our backs in this." Clint said with a smile.

"Well as much as we would like to stay and talk with you all, these little ones need to sleep in a bed and not our arms." Natasha said as called the elevator.

Everyone quickly said goodnight as they got onto the elevator.
