Your dad was a very busy man, a genius, a hero, and an engineer. But he tried to make time to be a dad. When he wasn't there, he'd have a suit sit in your room and have FRIDAY watch to make sure you slept and ate and such. He loved you and you were his whole world. Sometimes, you'd feel pathetic, since, you were, technically, an accident. But you're the best thing that ever happened to him, but he just can't express it. Ever the deflective Tony..
You had taken up a habit recently. A horrible one, cruel and painful. Towards yourself. You were on the bathroom floor and in walked an Iron Man suit. It froze and stood there, you assumed it was just FRIDAY watching. It wasn't. Your dad was here, for the first time in a while and he came back to his baby hurting themself. You didn't realize until the suit became his normal outfit once again, metal disappearing and turning into the skintight fabric. He stared down at you with watery eyes.
