Natasha Romanoff walked down the hallways of the S.H.I.E.L.D. building. The woman tilted her head, walking toward the end of the hall, staring at a door. She knocked on the door.

"Come in," A man's voice called from the other side.

Natasha opened the door, walking inside. She looked at the chair in front of her that was facing away from her. "You wanted to see me?"

Nick Fury was sitting on the couch. "Yes, I did."

Natasha looked at the man sitting on the couch, looking at the chair, raising an eyebrow as she looked back at Fury.

The chair turned around, showing a little girl with red hair and blue eyes. "Hey, Mom."

Natasha gave her daughter a look. "Anna, I thought I told you to stay with Clint."

"Uncle Clint is busy," Anna told her, shrugging her little shoulders. "Pops told me I can come over to his office since I was bored."

Fury shrugged. "No trouble with that." He stood up. "I want you to go on a mission."

"Which is?" the woman asked.

Fury stood next to Anna, put one hand on the chair and the other grabbing a file. He handed it to Natasha. "You know Tony Stark?"

The little girl gasped excitedly. "I know!"

Natasha smirked a little at her daughter, taking the file and opening it. "Yes." She looked at her daughter. "I know."

Fury smirked. "Good. I need you to go undercover. I've heard Mr. Stark put his company over to his assistant, Miss Potts."

"He did?" Anna asked, tilting her head.

"He did," Fury confirmed.

"So?" Natasha asked, putting the file on the desk.

"I want you to keep an eye on Mr. Stark for me," Fury told her. "But also I want you to assess whether he will suitable for a plan to bring together a group of people with unparalleled talents."

Natasha considered it for a long moment, crossing her arms over her chest. "Okay. I'll do it."

Anna's eyes grew wide. "Can I come?"

"No," her mother told her.

"Why not?" Anna whined.

"It's a mission," Natasha pointed out. "I don't want you to get involved in those things any time soon."

Anna looked at Fury for help. "Pops?"

Natasha gave Fury a look. "Nick?"

Fury looked between the mother and daughter in slightly amusement. "Oh, sometimes the cutest thing can be very dangerous."

Anna slowly smiled, knowing she got him on her side in this.

Natasha walked in the Stark mansion in Malibu, California, having a notary in hands. She walked in a room that allowed the view of the ocean outside. Pepper Potts was standing there while Tony Stark and Happy Hogan were boxing, but the two men stopped as they saw her walking in.

Pepper looked at Tony. "I promise you this is the only time I will ask you to sign over your company."

Natasha walked toward Pepper, telling her where to sign. "I need you to initial each box."

Happy hit gently on Tony's head to get his attention back. "Lesson one. Never take your eye off -" Tony kicked Happy with his foot, throwing him back into the corner of the ring. "All right, I'm done."

Tony pointed at Natasha. "What's your name, lady?"

"Rushman," Natasha told them, giving them her under cover name. "Natalie Rushman."

"Front and center," Tony told her. "Come into the church."

"No," Pepper told him. "You're seriously not gonna ask..."

"If it pleases the court," Tony answered. "Which it does."

Natasha looked at Pepper. "It's no problem."

"I'm sorry," Pepper told her. "They're very eccentric."

Natasha walked toward the ring, getting in as she looked at Tony.

Pepper sat on the chair, looking at her phone.

Tony looked at Natasha, taking a drink of water.

Natasha kept looking at Tony.

"What?" Tony asked. Natasha didn't answered, raising an eyebrow. Tony looked at Happy. "Can you give her a lesson?"

"No problem," Happy told him.

Tony got out of the ring, walking toward the chair beside Pepper. He sat down, whispering. "Pepper."

"What?" Pepper asked.

"Who is she?" Tony asked.

"She is from legal," Pepper told him. "And she is potentially a very expensive sexual harassment lawsuit if you keep ogling her like that."

"I need a new assistant, boss," Tony told her.

"Yes, and I've got three excellent potential candidates," Pepper told him. "They're line up and ready to meet you."

"I don't have time to meet," Tony told her. "I need someone now. I feel like it's her."

"No, it's not," Pepper told him.

Happy looked at Natasha. "You ever boxed before?"

"I have, yes," Natasha answered.

"What, like, the Tae Bo?" Happy asked. "Booty Boot Camp? Crunch? Something like that?"

Natasha cleared her throat.

"How do I spell your name, Natalie?" Tony asked, clapping his hands three times.

A computer appeared in the table beside him.

"R-U-S-H-M-A-N," Natasha told him.

"What, are you gonna Google her now?" Pepper asked.

"I thought I was ogling her," Tony told her. He swiped through the information he found. "Wow. Very, very impressive individual."

"You're so predictable," Pepper told him. "You know that?"

"She's fluent in French, Italian, Russian, Latin," Tony told her. "Who speaks Latin?"

"No one speaks Latin," Pepper told him. "It's a dead language. You can read Latin or you can write Latin, but you can't speak Latin."

Tony pulled up a picture of Natasha and Anna. "Oh, who's that little thing?" Pepper looked closer. "Is that a daughter? Does she have a daughter?"

"Apparently," Pepper told him. "And she looks very adorable."

Tony pouted. "I'm more adorable."

Pepper rolled her eyes, amused.

Natasha looked toward them.

"Rule number one," Happy told her. "Never take your eye off your opponent."

Happy slowly moved his boxer glove toward Natasha's face. Natasha caught his arm, flipping up to wrap her legs around his neck, flipping them to the mat of the ring.

Pepper gasped. "Oh, my God!" Pepper and Tony stood, walking closer. "Happy!"

Natasha stood. Happy slowly stood.

"That's what I'm talking about," Tony told them.

"I just slipped," Happy told them.

"You did?" Tony asked sarcastically, ringing the bell.

"Yeah," Happy told him.

"Looks like a TKO to me," Tony told him.

Natasha climbed out of the ring, looking at Tony. "Just... I need your impression."

Anna stood at the side, watching.

"You have a quiet reserve," Tony told her. "I don't know. You have an old soul."

"I meant your fingerprint," Natasha told him.

Tony nodded awkwardly. "Right."

Tony put his thumb in ink, putting it on paper.

Pepper walked closer. "So, how are we doing?"

"Great," Tony answered. "Just wrapping up." He smiled. "Hey. You're the boss."

Pepper smiled.

Anna cleared her throat, slowly walking closer.

Natasha, Pepper and Tony looked at her.

"Ava," Natasha told her, calling her by her undercover name.

Anna stood closer to her mother, looking up at Pepper and Tony. "Hey."

Natasha put her hand on Anna's shoulder.

Pepper smiled at the little girl. "Hi, there."

Tony nodded. "Hey, kid." He looked at Natasha. "Your daughter?"

"Yes," Natasha answered. "I hope it's not trouble she's here. She, uh." She shrugged, looking at Tony. "She's a big fan of yours and she wanted to meet you."

Tony raised an eyebrow in surprise. "She is?" He looked at Anna. "You are?"

Anna nodded. "Yes, sir."

"Please, call me Tony," Tony told her, holding out his hand. "Let's shake it, kiddo."

Anna smiled, shaking Tony's hand.

"It's not a problem she's here," Pepper told her. She looked down at the girl. "Hey, my name is Pepper."

Anna shook the woman's hand. "Ava."

"Will that be all, Mr. Stark?" Natasha asked.

"Yes, that will be all, Ms. Rushman," Pepper told her. "Thank you very much." She looked at Anna. "Hope to see you again very soon, Ava."

"You too," Anna told her. She looked at Tony. "It was nice to meet you, Tony."

"You too, kiddo," Tony told her.

"Come on, sweetheart," Natasha told her.

Natasha and Anna walked away, out of the room.

Once out of the room, Anna looked up at her mother, grinning. "I met Tony Stark."

Natasha smiled in amusement, chuckling.
