All I have to say is because Tony Stark loves his daughter.

- Love-Me-Some-Pie

*Age 6*

Tony glances sideways, making sure his daughter is still sitting on the cool marble floor playing with her ponies. He turns back to his work, stealing glances at Margo just to make sure she's okay.

"JARVIS," Tony says, breaking the silence in the room. "Turn up the music."

"Yes Sir." JARVIS answers, turning up the music as Tony happily sings along to it.

Tony goes back to his work, working away on his new project, affectionately tuning out anything and everything but his daughter. He steals another glance in Margo's direction, feeling relieved when he finds Margo still sitting there happily playing with her ponies.

"Daddy." Margo says, tugging on Tony's shirt. "Daddy."

Tony turns slightly, laying the wrench he's holding on the table next to him. "What is it Princess?"

Margo bites at her lip, holding out one of her ponies to her Father. "Play with me?"

It was a simple question, and all Tony could do was smile happily and take the pony from the small girls hands. "Sure thing Princess."

They sit in the floor and play for what seems like hours with the little ponies. Margo making up some elaborate story with the ponies while Tony merely nods and plays along. Eventually Margo gets bored with the ponies and tries to convince her Father to play something else with her.

"Please Daddy!" Margo begs, taking Tony's hand and trying her hardest to drag Tony to her room.

"Princess, I've got lots of work to do, can I take a rain check?" Tony offers, removing his hand from his daughters grasp.

Margo pouts at Tony. "Please Daddy." She tries again.

Tony sighs and rubs the bridge of his nose. "Princess..." Margo gives Tony her best puppy dog eyes. "Fine." He breathes out, letting Margo take his hand again and drag him to her room.

Natasha sighs, entering Tony's home, she's taking Margo for the weekend and she's here to pick her up. "Tony!" She yells, getting no answer. She taps her foot on the ground impatiently. "JARVIS, where's Tony?"

"He's in Margo's room Miss." The AI replies.

"Thank you JARVIS." Natasha says, slowly and quietly climbing the steps to Margo's room.

It takes Natasha two minutes to actually reach Margo's room and she grins at the sight in front of her, sneaking off to grab a camera. She's back in her spot in front of Margo's room moments later, camera in her hands. She quietly snaps a few pictures before finally making her presence known. "Stark, that hair style really suits you."

Tony jumps from his spot on the floor, causing Margo to pull at some of his hair. "Don't you knock?"

Margo frowns and tugs at Tony's pants. "Daddy! I wasn't finished fixing your hair for our tea party!"

Tony grumbles something inaudible and tugs the pink hair ties out of his hair, combing it with his fingers. He pulls a few clips and bobby-pins out of his hair before glaring at Natasha. "You should really knock."

"I did knock, but it seems you were too busy getting your hair done for a tea party to hear." Natasha shoots back, smiling at Margo as the little girl grabs her overnight bag. "Ready to go Margo?"

Margo nods and grabs Tony the teddy bear. "Yes Aunt Natasha." She walks over to Tony and hugs him. "Bye Daddy."

Tony kisses Margo's cheek. "Bye Princess, be good. And Natasha, I'd appreciate it if you don't teach her any more "ninja moves" this time." He pats Margo's head, following her and Natasha out of the child's room.

"No promises." Natasha mutters, taking Margo's hand.

"Thanks for playing tea party with me Daddy!" Margo yells, waving goodbye to her Father as she follows Natasha.

Tony smiles, playing tea party with Margo wasn't all that bad, so long as he doesn't get caught.
