A/N: Another chapter of fluffy fluffiness :)
The next day, Clint dropped into Tony's workshop via the vent. "Hey Tony."
Tony bolted out of his half-dozing position. "Clint! How did you- stop going in the vents, man."
"I need your help," Clint said.
"Already tired of your married life with kids?" Tony asked.
"Nope," Clint said promptly. "I want to find Natasha a ring."
Tony raised an eyebrow. "You know you two are doing this all backward," he said. "First you got a kid, now you're getting her a ring?"
"And then we kind of want to renew our vows," Clint said. "Since they were fake-ish the last time."
Tony rolled his eyes. "What kind of jewels does she like?"
"Diamonds," Clint said. "And rose gold."
"I'll recommend my jeweler to you," Tony replied, throwing a holographic screen towards Clint with the website already up. "Here, look through that."
Clint poked through pictures for a while, making little 'hm' noises once in a while.
Tony glanced at him awkwardly. "You, uh, have the money to buy this thing on government salary?" he asked. "I don't want you to be bankrupt before your kid hits college."
Clint smirked. "Remember all those years I was a mercenary for hire?" he asked. "I've got enough to retire to a private island if I wanted to."
"Oh." Tony nodded. "Good for you. Not the hired mercenary part, but the money part."
"Yes thank you Stark." He enlarged a photo of a simple rose gold ring with a diamond in the center. The setting looked vaguely like a spider. He smiled. "This one."
"Good choice," Tony said. "It's beautiful."
JARVIS worked with Clint to order it, and that was that.
That week they renovated the living floor where Barton and Romanoff lived, and turned the suites into one large apartment, with one master bedroom and a room for Allie right across the hall. It was slightly bigger than her old room but it was decorated just the same, with the addition of a photo wall. The one two pictures up so far were one of Allie and her new parents, and one of Allie and the Avengers.

One day, Allie woke up and decided to be a bird. She was a beautiful blue bird with black feathers on her wings, and she fit in Clint's open palm, fluffing her feathers adorably with her little beak. She chirped up at him happily.
His heart melted, and he kissed her little head. "You are the cutest bird ever," he told her.
She cheeped, fluttered her wings, and landed on his shoulder, her little feet catching into his T-shirt. She nestled into the crook of his neck happily.
He let her sit there while he fixed his coffee and walked down to the common room, the tiny ball of heat against his neck making him smile like an idiot. "Good morning," he announced to the still-sleepy Avengers.
"Morning," Steve said, not looking up from his paper. "Where's Allie?"
The little blue bird flew to Steve and landed in front of him.
Steve smiled. "Allie?"
She hopped forward and preened.
"You hungry doll?" Steve asked.
She shook her head and went to sit in Bruce's mop of unruly curls.
The scientist merely smiled and continued to eat his oatmeal.
Clint snapped a picture to show to Natasha later.

A week later, the diamond ring had been safely delivered to the Tower, and hidden in Steve's sock drawer. Two days after that, the Avengers, Coulson, Jane, Darcy, and Allie gathered in the hall at eleven AM. Before Thor and everybody, Clint and Natasha renewed their vows, and Clint presented his wife with the ring he'd picked out. She loved it, and kissed him in front of everybody.
They had a reception in the banquet hall in the next room, and there was dancing and food provided by Stark. Pepper had planned all of it, and she was thrilled that everything was working out perfectly. The "newlyweds" had their first dance, and then Clint danced with his new daughter. After that, everyone cheerfully flooded onto the dance floor.
Allie sat with Coulson and Darcy for a while, and then Tony very formally asked her to dance. She accepted, and he twirled her around on the dance floor as she giggled madly.
Darcy caught them at the end of the dance and held out a hand. "May I cut in, Mr. Stark?"
Tony bowed out gracefully, and Allie giggled as she and Darcy danced a shortened version of the Cupid Shuffle. Pepper got a picture of that for the photo wall, and one later, when Clint was holding a drowsy Allie and he and Natasha were dancing the last slow waltz of the night.
The "newlyweds" bowed out after they'd said goodnight to Allie, and headed off for two weeks on an undisclosed honeymoon, since their original honeymoon was a mission in Croatia.
Allie was perfectly happy to stay with her "uncles" for those two weeks, and found herself pleasantly spoiled by Coulson, Tony, Thor, Steve, and Bruce, in that order.

When Natasha and Clint came home two weeks later, they were greeted by a quiet Tower. "Where is everyone?" Clint asked. He would've thought at least Allie would've come to give them hugs.
JARVIS spoke up. "Thor and Captain Rogers are buying groceries, Agent Coulson and Dr. Banner are in the gym, and Sir is with the little miss in his lab."
Clint paled. "The lab? Alone?"
"I am keeping a very close eye on both of them, Agent Barton," JARVIS said primly. "I would not allow any harm to come to the little miss."
"Thanks, J," Clint said, giving the ceiling a quick grin.
The two of them stopped at their floor to drop off their suitcases, and went up to Tony's lab. They stopped in the doorway to smile at the scene in front of them.
Allie was wrapped in a small white lab coat, sitting at one of the stools in front of Tony's workspace, and next to her was Dummy. Tony sat on the other stool, and all three of them were carefully assembling what looked like a..
"What are you building, malyshka?" Natasha asked, giving them an amused smile.
"Mommy!" Allie jumped from her stool and ran to Natasha and Clint.
Natasha scooped her up and pressed a kiss to her cheek. "Hi, baby. Did you miss us?"
"Yes, yes, yes, kind of," Allie said, with all the honesty of childhood. She planted a kiss on Natasha's cheek and hugged her tightly.
"What about me, punkin?" Clint asked, giving her an exaggerated pout.
Allie leaned over to hug him and he scooped her up, blowing a raspberry on her neck as she screeched happily. "I missed you too, daddy. Kind of."
"Kind of?" Clint asked. "Why kind of?"
She smiled guilelessly. "Because dey let me has pancakes and ice cream for breakfast every day you were gone."
Tony hid behind his robots as Natasha turned to him. "First of all, that was Coulson. Second of all, her little pout is killer. If our villains decided to copy it, we'd all be conquered."
She glared at him, and then turned to Allie. "What were you and Uncle Tony building?" she asked.
"A robot," Allie said proudly. "From scratch and everytin'."
"A robot? What for?"
"For science," Allie said, grinning.
"She's learning robotics, engineering, and basic programming with me," Tony said. "I'm going to give it a dialed-down version of JARVIS that will keep her safe whenever she has it with her."
"Awesome," Clint said. He kissed Allie's head. "But now it's time for lunch, don't you think?"
"Lunch!" she cheered, wriggling down to the floor. She kissed Dummy on the claw and ran out the doors.
"No running in the labs!" Tony called after her, and shooed the others away. "Go, have lunch, reconnect with your child. She's starting to learn to read, by the way."
"We were only gone for two weeks," Natasha said, impressed.
"Yeah well, you left four geniuses and a ninja agent in charge of your kid. What'd you expect?"
A/N 2: I'm taking plot suggestions for the next few chapters, if anyone has any ideas for cute interactions or character growth.
