Tony knew you better than anyone ever has. You were basically his world and main priority the second he found out one of his past flings was pregnant with you. When you were born, he just took you. Your mother didn't want a child, and he was rich and could afford it. So why not?

Tony raised you, caring over scraped knees, teaching you to be his little lab assistant. Luckily, you took after him in the fact that you're genius. You're mini-stark. When he would go on missions, as iron man, he'd make sure that you were comfortable and safe at home with one of the other avengers or even using Jarvis to watch.

The being mini him thing came with the down side. Tony has always had metal issues. Even if he buried them down, they effected him deeply. This was the one thing he didnt want you to suffer with, his bright and joyful child. Now dull and locked away.

Right now, its late. You and Him got into an argument around lunchtime. It was stupid, something where he was questioning why youre not the same as you were. The fight lit up, and you stormed off. Tony has been working in the lab for hours. Bruce ended up giving up on trying to get Tony out.

You're sitting by the window, as the elevator doors open. Your dad walks out, he looks tired. With a mix of every other emotion. Tony looks up, meeting your gaze across the room. When his eyebrows furrow. Knowingly, he felt intently guilty, and worried.
