Tony's daughter

You stood by the glass door, clutching a tablet with the updated blueprints for your own armor stabilizer. You'd been working on them for three weeks. All by yourself. Without Jarvis or Friday to prove you were worthy of the Stark name.
"Tony, look at this node," Peter Parker said, waving his arms excitedly in front of the holographic screen. "If we replace the polymers with coated carbon fiber, the web shooters won't jam in subzero temperatures!"
"Great idea, kiddo," Tony smiled softly, ruffling the boy's curly head. His eyes shone with the same pride you'd been trying so hard to capture for years. "FRIDAY, run a simulation for Peter. And order that Brooklyn pizza he likes."
"Pom-pom! We're geniuses!" Peter raised his fist in the air triumphantly, but stopped short when he spotted you in the doorway. "Oh, hi, Evie! We're just... well, upgrading a few things. Want to come with us?"
Tony turned. The warm smile intended for Peter was instantly replaced by his usual, slightly tired mask of businesslike concentration.
"Hi, sweetie. Is something wrong? If you need some pocket money or new gadgets, Pepper's in the office, she'll sign everything."
You swallowed the bitter lump in your throat. The tablet felt incredibly heavy in your hands.
— No, Dad. I wanted to show you the plans. For my suit. Remember, you promised to look at them last weekend?
Tony frowned for a second, clearly remembering, and then, guiltily but somehow too frivolously, he spread his hands:
"Oh, right. Sorry, sweetie, it slipped my mind. Peter and I are stuck testing his new patrol suits. Can we do this later? Leave the tablet on the table, Friday can check for errors."
"Friday will check," you repeated quietly. "Understood."
Peter looked between you and Tony, clearly feeling out of place.
"Mr. Stark, maybe we should take a break? Ivy's plans look cool, I saw them out of the corner of my eye..."
“It’s okay, Peter,” you interrupted him, putting on your fakest smile. “Don’t get distracted. You have great ones.”
