"Wait, so she isn't on a mission?" Fury shook his head. "Then where the fuck is she?"

"Stark, calm do-"

"Calm down? How can I calm down, when the woman that I love has been missing for 2 days?!" Tony basically yelled. Clint entered the room, noticing that there was something wrong.

"What's going on?" Clint asked with a concerned look.

"Agent Romanoff," Fury said simply.

"What about her?"

"She's missing. And she's not on a mission," Tony said looking at the ground clearly upset.

"Natasha's missing?" A familiar voice said. "Then shouldn't we do something?"

"Banner, it's not that simple," Fury said with a straight face even though he was worried.

"Natasha can take care of herself, she must've run," Clint confidently said.

"What would she have run from?" Tony asked.

"Red Room," Bruce answered.

"No, we burnt the place to the ground. Killed the people in control," Clint replied. "When I say 'run', I mean she left on purpose."

"Then, we track her," Tony said. "I have the softwar-"

"If Natasha doesn't want to be found, we won't find her. If she did run, I hope that she decided to start a new life. She deserves it."

.

Days turned into months, months turned into years. No sign of Natasha no matter what they've done. After 4 years of looking, Clint got a message. The message read:

Clint,

It's been 4 years since I've seen you, and I know you're worried, but I'm fine. I've been blessed with the most wonderful thing in my life, but I left because I didn't want it in that environment. I know Tony's looking for me, so would you please let him know I'm okay, and that I'm safe. Don't try and find me at the return address because I won't be there. I sent this from the house of a woman I know by the name of Nicole Renson. I didn't give her my current address so she won't be of any use. And if you try to kidnap her or get any information out of her, she will kick your ass.

At first, Clint didn't know who sent the letter but he quickly caught on. He went downstairs to see Tony carrying a 3-year-old named Jack, Tony's only child.

"Tony?" Tony set the kid down and told him to go play.

"Yeah?"

"It's a letter. I'm pretty sure it's from Natasha but it has no name."

"Natasha? Does it have a return address?"

"Yeah, but...just read the letter."

"Nicole Renson. I know her," Tony said setting the letter down. "She and Natasha were friends, and, telling by this letter, they still are."

"Why didn't Natasha email or text?"

"It's harder to track letters, even with my tec."

"So we interrogate Renson."

"Renson'll kick both of our asses with one hand tied. She's good. Almost better than Natasha in hand-to-hand."

"Natasha can't kick both of our asses so how will Renson?"

"She's a mutie."

"She's a what?" Clint asked.

"Renson's a mutant."

"So, what if we knock her out?"

"If we, somehow, manage to knock her out, I bet she has a few muties living with her."

"And if she doesn't? Tony, we have a chance to get Natasha back. Don't you want that?" Clint said raising his voice slightly.

"Of course I want that. But if Natasha wanted to see us, she would've fucking came back, Clint. Do you not understand or is your head still in the clouds?" Tony said raising his voice as well.

"B-"

"She doesn't fucking want us, Clint," Tony said slowly then turning around and heading into the workshop.

Natasha lives in a penthouse with a 16-year-old girl, Samantha Romanova. Samantha has green eyes and blonde hair with pale skin like Natasha's.

.

Samantha was in school when an alarm went off. Everyone started to stand up when a huge black, alien-looking, thing entered the room and started shooting lasers out of its mouth, hitting and injuring the teacher. Samantha broke a leg off of a chair and threw it at the creature, hitting it directly in the head and killing it. She called her mom and told her about the situation.

"Hey, I heard about the unknown evacuation, are you ok?" Natasha asked.

"I'm fine, it's just a huge black thing shot a blue laser out of its mouth and hurt Mrs. Nelson."

"What?"

"Don't worry, it's dead just get here fast."

"Ok I'm on my way, stay put." Samantha hung up the phone and, despite her mother's orders, she left the room and wandered down the hall. She spotted a few more and quickly made her way into another classroom. It was surprisingly empty, and Samantha assumed everyone evacuated. A few minutes later Natasha found her and tossed her a gun. Natasha taught Samantha how to protect herself so Samantha knew how to use a gun. Another creature entered the room, and right afterward glass flew everywhere.

Natasha turned around to see two men in Iron Man suits. Shit, she mumbled. As soon as the creature started shooting lasers, Samantha repeatedly fired until it was on the ground. Tony Stark took off his helmet and watched as the girl started shooting the creature again. Samantha stopped shooting and looked behind her to she Natasha and Tony Stark looking at her with a raised eyebrow.

"What? It twitched, I just wanted to make sure it was dead." Tony looked from Samantha to Natasha.

"Well, if it isn't the 'Black Widow'. I knew they called you the Black Widow for a reason," Tony said coldly.

"Sam, you should go home," Natasha said locking eyes with Tony.

"Are you coming?"

"I'll catch up."

"Ok..." Samantha trailed off as she left the building.

"Who's the kid?" Tony asked.

"No one. What're you doing here?"

"My job. You?"

"What are those things?" Natasha asked ignoring Tony's question.

"I'm pretty sure it has something to do with Loki. We've gotten rid of the rest of those things...Why'd you leave?"

"If I tell you it's not going to change that past."

"I don-" Tony was cut off by the other Iron Man.

"Not to interrupt this lovely reunion, but don't we have a party to get ready for?"

"Yeah, wanna come, Tash?"

"No, I've got better things to do," Natasha said walking towards the classroom door.

"Please, just this party and I never have to see you again." Natasha stopped. "You owe me this."

"I don't owe you anything," She said turning back around to face Tony.

"Last I saw you, we were both naked in my bed," Tony said making Natasha roll her eyes and turn back around. The other guy in an Iron Man suit took off, leaving Tony and Natasha alone. "And I was madly in love with you. When you left I was heartbroken...I've never been that broken in my life. I wasn't that broken when you left the first time, but I didn't think you were going to leave again. So yes, you do owe me. You owe me 10 years of suffering, and all I'm asking is one party." Natasha turned back around again to see Tony, his expression was dull.

"And maybe a hookup," he added with a smirk.

"Fine, I'll go to the party. And we are not hooking up."

"Fine. Party is at 10. And, uh, who was the girl?"

"Samantha, she's, uh, my, er, daughter."

"Daughter?!" Tony asked surprised.

"Yeah..." Natasha trailed off.

"Bring her."

"Ok..."

"Anyway, I'll see you at the party, hun," Tony said after a few seconds of silence. Natasha stood there thinking about how she missed him as he took off.

.

8:00

Natasha picked out a black dress with a slit up to the thigh with black heels and red lipstick. Samantha had on a red skin-tight dress with red lipstick.

They got in their car and headed to Avengers Tower.

Before they entered the building, Samantha asked, "How do you know him?"

"Know who?" Natasha asked.

"Stark."

"He was a mission from the Red Room."

"So why is he alive?"

"I, uh, fell in love with him, and couldn't kill him."

"Oh..." She said following Natasha to the door. A young woman answered and allowed them in.

"Natasha! I was afraid you'd abandoned me."
