Chapter 21-Reunited

**Natasha**

Clint stared at her for a long time once she'd broken the news to him, not a single emotion crossing his face.

"Clint?" Natasha whispered as she took a few steps towards him. "Are you alright?"

He lifted his head to look at her and, much to her surprised, he began to laugh hysterically.

"What the hell is so funny?" She asked, slightly taken aback by his reaction. She had expected a lot more yelling…

"You just…I can't…" Clint said between spurts of laughter. "You're not serious!"

"Yes, I am." Natasha growled irritably.

"Oh, drop it Nat." He chuckled. "I know you can't get pregnant. You told me, remember?"

"Clint, this isn't a joke." She said seriously.

"Right." He laughed again. "So you're telling me that the reason you were gone for an entire year was because you were pregnant? Honestly, why would you do that?"

"Because I knew you'd want to keep the baby." She mumbled.

Clint covered his mouth to prevent himself from laughing out loud again. He still didn't believe her, and Natasha was starting to get pissed. She closed the distance between them and grabbed his face in her hands.

"Goddamn it, Clint, look into my eyes!" She said forcefully. "Do I look like I'm fucking with you?"

As soon as he saw the seriousness in her eyes, his smile fell from his face.

"But I thought…you said…" He stuttered.

"I know what I told you, and I swear to God I thought it was true, but somehow, it happened." Natasha said as she stroked his cheek.

"Why the hell didn't you tell me!?" He suddenly exclaimed, swatting her hand away from his face.

"I was scared." She said calmly.

"And you thought running was the best solution?"

"At the time, yes."

Clint ran his hands through his hair and began to pace.

"Fuck." He muttered as he put the pieces together.

"I'm so sorry, I should have told you…"

"Yeah, you should have!" He yelled.

"Look, I know you're angry and overwhelmed, but there are a few more things you need to know." She told him.

"Where is it?" He suddenly asked, completely disregarding everything she'd just said. "Where's the baby?"

Natasha opened her mouth to try and explain everything in the least confusing way possible, but she couldn't figure out how to word it.

"Nat, what did you do?" Clint asked again, mistaking her silence for guilt.

"I didn't do anything." She said soothingly. "They're fine."

"Was the baby in New York during the invasion?"

"No, they were in Ireland."

"Why do you keep saying 'they'?" He wondered, his eyes widening in sudden realization. "No…"

"I had twins." She explained with a small smile and a shrug.

"Twins." Clint repeated quietly before falling backwards onto the floor.

"Oh my God!" Natasha exclaimed as she rushed to his side. "Clint Barton, I know you did not just faint."

She gently smacked his face a couple of times before cursing quietly and running to grab a cup of water. As soon as she returned, she dumped the water on his face and sighed in his relief when he opened his eyes.

"Welcome back." She muttered.

"What happened?" He said as he sat up and rubbed the back of his head.

"I told you that you were the father of twins and you fainted."

"I fainted?" Clint said in confusion.

"Yes, you did. Now don't do it again." She told him as she helped him sit up.

He scooted over to the bed and leaned against it, covering his face with his hands.

"Are you okay?" Natasha asked.

"I'm fine." He mumbled. "Just give me a second to wrap my head around this."

She sat next to him in silence as he repeatedly rubbed his hands across his face. It wasn't until nearly an hour later that he finally spoke again.

"Are they still in Ireland?" He asked quietly.

"Yes." She whispered.

"Did you…" Clint swallowed hard as he prepared to ask his next question. "Did you give them away?"

"I was going to." She admitted. "But as soon as I held them in my arms, I knew that I could never go through with it."

"So…you want to keep them, then?" He asked with a hint of shock.

Natasha nodded and smiled.

"Oh, thank God." He sighed in relief before leaning over and planting a tender kiss on her lips.

"I assume you're happy about this?" She laughed when he pulled away.

"Duh!" He said with excitement.

"Do you want to see them?"

"Yes!" Clint exclaimed.

Natasha grinned as she unfastened the golden heart locket that was hanging around her neck and handed it to him. He quickly opened it and gazed in wonder at the pictures of his twin children.

"They're fraternal twins." She told him. "A boy and a girl."

"What are their names?"

"This is Gavin." She said, pointing to the picture on the left half of the locket. "And that's Charlotte."

"Gavin and Charlotte." Clint repeated thoughtfully. "Interesting."

"What?" Natasha asked curiously.

"I get why you picked Charlotte, but why Gavin?"

"Well, I picked both names because of their meanings." She explained. "Charlotte means 'strong', and Gavin means 'little hawk.'"

"Really?" He said with a raised eyebrow. "That is interesting."

"What is?"

"Are you sure you didn't name the girl Charlotte because it happens to be the same name of the spider in Charlotte's Web?"

"What? That's ridiculous." Natasha shook her head as hints of pink colored her cheeks.

"I knew it!" Clint said victoriously. "You wanted both their names to relate to our codenames! That's so cute."

"Okay, okay, you got me, now shut up." She blushed.

"There's nothing to be embarrassed about." He assured her as he closed the locket and refastened it around her neck. "I love the name Charlotte."

"Good." She mumbled.

"I also love you." He told her, kissing her temple.

"So, you're not mad then?"

"Oh, no. Of course I'm mad. You should have told me that you were pregnant." Clint said seriously. "But, I'm more than willing to forgive you if that means we get to have a family together."

Natasha smiled and threw her arms around him.

"I love you, too. And I'm sorry that I didn't tell you. It was stupid." She whispered.

"It's okay. You were scared, I get it."

"Why are you so nice to me?"

"Because if I wasn't you'd kill me." He said bluntly.

"That's not true." She giggled.

"Oh, so does that mean I can yell at you?"

"I'd prefer that you didn't." Natasha said into his shoulder.

"Okay, but only because you're pretty." Clint smiled. "So, what do we do now?"

"Well, I'll need to make a call to work out how we're going to get them here. After that we'll probably be able to have them home by the end of the week." She said positively as she got to her feet. "I can make the call now."

"Okay." He said with a mixture of excitement and nervousness. "Let me know what the plan is as soon as you find out."

"Of course." Natasha shot him a final smile before grabbing her phone off the bed and walking out of the room.

As she dialed Maggie's number, she couldn't help but breathe a sigh of relief. She'd finally told Clint the biggest secret she had ever kept from him, and he'd taken the news relatively well. He didn't hate her for not telling him sooner and he also seemed really excited that they were going to raise a family together. But most importantly, Natasha knew that by the end of the week their babies would finally be home where they belong. Everything had worked out in her favor for once, and for that she was truly grateful.

**Clint**

Two days later…

"You know, Clint, pacing back and forth isn't going to make you any less nervous." Natasha sighed as she watched him walk around the S.H.I.E.L.D. debriefing room at the New York HQ. They had been waiting here for her friends to arrive with their children for nearly two hours, and the suspense was starting to get to him.

"Sorry, I just can't sit still right now." He told her as he continued to pace.

"You know, you're the one that said you'd rather Maggie bring the twins to us so we wouldn't have to fly all the way to Ireland and back." She reminded him.

"So?" Clint said questioningly.

"So now you're going to have to sit here and wait." Natasha told him, crossing her arms.

"What if I end up being a terrible father?" He wondered aloud.

"Oh, for God's sake, do not start." She pleaded.

"What if we forgot something? What if-" He was cut off by Natasha's hand over his mouth.

"That's enough with the 'what ifs'. You're going to be an amazing father, and you and I both triple checked that we had everything we needed. It's okay."

"But-"

"No buts! We have diapers, baby food, formula, blankets, toys, and a place for them to sleep. Maggie said she'd bring all their clothes over with her so we didn't need to worry about that. Everything is fine." She assured him before leaning in and giving him a comforting kiss. "You just need to relax."

"Okay." Clint said, taking a deep breath. He finally started to feel himself calm down a little when there was suddenly a loud knock on the door. His muscles immediately tensed back up and his heart rate accelerated way beyond its average rate.

Natasha clearly noticed the sudden change because she grabbed his hand and gave it a gentle squeeze.

"Hey," She said softly. "I love you."

"Love you too." He breathed anxiously as she called for the person that had knocked to enter.

The door opened and Fury stepped inside followed by two others, both of them holding baby carriers.

"Agents," the director greeted them. "Your children have arrived."

"Thank you, sir." Natasha nodded to their boss appreciatively as he made his way back out of the debriefing room. As soon as he was gone, she released Clint's hand and rushed forward to give the man and woman that had followed Fury in hugs.

"We've missed you so much!" The woman exclaimed in a thick Irish accent.

"I've missed you too." Natasha replied before turning back to Clint. "As you've probably guessed by now, this is Clint." She told them, gesturing in his direction. "Clint, these are my very dear friends Maggie and Craig."

"It's so nice to finally meet you!" Maggie said with a smile before running up and hugging him.

"It's nice to meet you too." He said as he awkwardly hugged her back. "Thank you for taking such good care of Natasha and the twins."

"It was no trouble." The younger girl assured him. "I'm just glad everything worked out in the end."

"Clint," Natasha suddenly called his name. "Come here."

He moved towards her as she bent down and lifted one of the infants out of its carrier. She hugged the baby close to her chest and kissed it on the head before offering it to him. He hesitated.

"Go on, take her." She urged him.

"I don't know if I-"

"Just take her." Natasha ordered, holding Charlotte out towards him.

He sighed, carefully taking the baby in his arms and cradled her against his chest. Charlotte, who had been sleeping, opened her eyes and looked at her father curiously.

"She's got your nose." He told Natasha with a smile.

"And your eyes." She replied, lifting Gavin out of his carrier. "With this little guy it's vice versa. My eyes, your nose."

"He's got my nose?" Clint said with a sympathetic laugh. "I feel for him."

"Your nose is fine." Natasha rolled her eyes.

"They're so perfect." He mumbled, stroking Charlotte's cheek.

"Yeah." She agreed. "We made some beautiful babies."

"And on that note, I think we're going to head out." Maggie suddenly chimed in from the other side of the room.

"You can't stay?" Natasha said in disappointment.

"No, you two probably want some time alone with the twins. Also, Craig and I need to get home. We've got a bit of planning to do…"

"Planning for what?"

Maggie grinned and held out her hand for Natasha to see.

"Oh my God! You two got engaged?" She exclaimed, examining the diamond ring on her friend's finger.

"Yep! Last week!" The Irish girl exclaimed.

"Way to wait until after I leave!" Natasha punched Craig's shoulder.

"Sorry." The young man shrugged.

"Don't worry, we won't forget to invite you all to the wedding!" Maggie promised. "But we really should get going."

"Okay." Natasha sighed as she pulled her in for a hug. "Thanks for everything."

"I'd do it again in a heartbeat." Maggie told her before turning to Clint. "It was nice to meet you."

"You too." He smiled. "Thanks again for being there for her."

"It should have been you who was there for her." She said with a quick glance towards a guilty looking Natasha.

"Weren't you just leaving?" Natasha asked with a raised eyebrow.

"Yeah, yeah…" Maggie waved her off as she pulled Craig out the door. "I'll call you!"

"Take care, guys!" Natasha waved goodbye and smiled as the door shut behind them.

"So," Clint whispered when he realized that Charlotte had fallen asleep in his arms. "What do we do now?"

"We take them home, dummy." She told him teasingly as she strapped Gavin back in his baby carrier.

"So, what? We just walk through the entire S.H.I.E.L.D. base with them for everyone to see?" He asked incredulously.

"What's wrong Clint? Don't you want to show off your beautiful new children to everyone we work with?" Natasha wondered, taking Charlotte from him and strapping her back into her baby carrier as well.

"Of course I do. I'm just shocked that you want to." He explained.

"And why is that?"

"People will talk. Spread rumors." He shrugged.

"You know what? I'm starting to think that rumors aren't necessarily a bad thing." She told him.

"How so?"

"Just look at us, Clint. We're parents!" Natasha said with a smile. "We would have never become parents if we hadn't slept together last year. And we would have never slept together if I hadn't come over to your place that day."

"And you would have never come over to my place if it hadn't been for…"

"A rumor." She finished his thought for him.

"Wow." Clint muttered. "Remind me to thank my ex-girlfriend for putting all this in motion."

Natasha giggled and pecked his cheek.

"C'mon," She said, handing him Charlotte's carrier. "Let's go home."

And so, they exited the debriefing room with their children and strode proudly through the S.H.I.E.L.D. New York base with their hands intertwined. As they made their way to the front, other agents that were passing by would stare at them and whisper things to their colleagues.

But Clint and Natasha didn't care. Because now, looking at their small family, they knew exactly what those assuming whispers and curious stares could do. They could give them things that they never even knew they wanted, things they wouldn't give up for the world. And to them, that was extraordinary.

**The End**


Well, there you have it! This is the end of A Onetime Thing! Can I just say that you all have been absolutely outstanding! Many of you probably don't know that this was originally supposed to be a two-shot where Clint and Natasha hook up, but you all insisted that I continue and look what happened. 21 freaking chapters! That's crazy! And it's all because of your kindness, so thank you for being my inspiration! You guys are THE best. So, now that I've gotten all that off my chest, it's time for an update as to what will be going on in the future. Some of you may know that I was working on another story before this one, Assassin's First Christmas, and I have yet to finish it. I don't have much left on it, so I'm going to try and quickly finish it so I can then begin Shattered, which was the story you all voted on. If things start going well for Shattered, then I will likely start posting another story so I have two going at once. My reason for doing this is because I have so many ideas and so little time that I'm trying to get them all done ASAP. So, if you're interested, look out for my upcoming stories which I will hopefully be posting soon. Also, don't forget to review the last chapter of A Onetime Thing and let me know what you thought of the story as a whole! Again, you all have been wonderful and I hope you'll consider reading some of my other stuff! Until next time, TTFN!

Love, Sarah ;)
