"Daddy!"

Tony Stark looked up from his work to see a little girl with dark red hair and dark eyes running into the lab. Six year-old Audrey Stark. "Monkey!" Tony smiled as his scooped the little redhead into his arms, loving kissing her cheek. "What are you doing here?"

"I came to see you," Audrey looked down at her father's work bench to see a black and gold Iron Man gauntlet sitting on the table, a small arc reactor built into the outside of the forearm. Audrey frowned. "Isn't that supposed to go here?" she asked, pointing to her chest.

Tony chuckled. "Usually, but for this new Iron Man, Daddy's trying to add some extra batteries so it'll run longer, fly faster and hit harder."

Audrey smiled. "Cool."

"It would be," Tony sighed as he gently placed his daughter on the ground "if I could get the thing to work without overloading."

"Daddy, will you play with me?"

"Not right now, monkey. Daddy has to finish working." Tony felt a tug on his heartstrings as Audrey pouted. "You know what, it can wait. It's playtime."

"Yay!"

Tony groaned as his cell phone rang. "Right after this. Hey Cap. What's going on?" As her father talked on the phone, Audrey's attention drifted to the gauntlet on the desk. "Yeah, I'll be at the facility next week. Tuesday at ten o'clock work for you?

"Daddy."

Tony motioned for her to wait as he continued talking on the phone. "Make sure Thor and Sam are there. I got some new flight patterns I want to go over with them."

"But Daddy."

"Tell Peter I've got a surprise for him. Might finally get him out of his Underoos."

"But Daddy!"

"Yes, Monkey," Tony responded finally "what is it?"

"I fixed it."

Tony glanced back and forth between his daughter's face and the weapon in her hands. "Cap, I'll call you back." Tony quickly hung up the phone and took the gauntlet from Audrey's hands, opening the back panel to look at the gears and wires, all perfectly stripped and set. He walked over to his lab bench and looked at his notes, the unfinished equations now completed in red crayon. "Audrey, how did you know how to do this?"

"My teacher says I'm good with numbers."

Tony glanced at the finished gauntlet curiously. "Monkey, are you sure this is going to work?"

The little girl nodded.

Tony paused, his mind racing. Her teacher had been trying to get a hold of him for a while now. And she was always taking things apart to see how they worked, that's why she was his little Grease Monkey. But could she really-? "Only one way to find out. Audrey, stand back," Tony motioned for his daughter to stand behind him as he strapped the gauntlet to his hand, aiming it a wooded practice dummy on the other side of the room. "JOCASTA, start filming. This is test five of the Mark fifty-two armor repulsor. Mark in three…two…one." The billionaire fired a massive blast, the force sending him staggering back as it burst from the palm of his hand. It sent the dummy flying, spinning in the air as it crashed into Tony's Audi, shattering the windshield. "It works. Audrey," Tony gasped as set his eyes on his daughter, an uncontainable smile on his face as his eyes blazed with pride. "You're a genius!" Audrey squealed as her father scooped her up in his arms, showering her with kisses. "You're a genius, Monkey! An adorable little genius!"

"Tony! Audrey! I'm home."

"Mommy's home!" Audrey smiled as she hoped out of her father's arm. "Wait 'till I tell her."

"Audrey, wait!" Tony quickly scooped his little girl into his arms as the color drained from his face, putting on a nervous smile "Audrey, Monkey. Do you remember Mommy's number one rule?"

"Don't play with Daddy's Iron Man toys," she recited.

"That's right. Now technically, you didn't play with Daddy's Iron Man. You just fixed it. But Mommy, she might not like it if she found out. And that might make us fight. Now you don't want Mommy and Daddy to fight, do you?"

Audrey shook her head. "Uh-uh."

"Good. So, what I need you to do is not tell Mommy about this," Tony hefted the gauntlet on his hand "Just for a little while."

Audrey frowned. "You want me to lie?"

"No, not lie," Tony disputed "just, you know, don't tell her about it."

"Like a secret?"

"Exactly!" Tony grinned "a secret. Can you do that, Monkey? Can you keep it a secret?"

Audrey smiled. "Okay Daddy."

"That's my girl." Tony smiled as he gave her a kiss and set her down. "Now go say hi to mommy. And remember, it's our little secret."
