A/N: Cheezy ending, but I wasn't sure where to go after parts one and two. The line in italics in each part is from a song, points if you can tell me who it's by!

Falling a thousand feet per second...

It only lasts a minute, but Steve is sure that the clock has died.

Toni had been working on modifications to her suit, and she had been sure that she had modified the power thrusters to allow flight, but with less power. And because Hank and Steve knew how the billionaire operated, they insisted they had to be there for her test flight. They hadn't been disappointed. Or rather, they hadn't been wrong, because Steve is definitely upset that Toni thought she could do something like this to them.

Toni never starts small. It is never "I wonder if I can make something that will let me fly", it's always "I wonder if I can make a suit of iron that will let me fly on earth and in outer space, and while I'm at it I should add weapons and a whole bunch of other things so I can beat up bad guys. And I may as well make it look like a man so no one will know it's me". Steve knows this. He knows it's why he loves her, even if he hasn't told her, or even gone on a date with her.

He had known she wouldn't start small now, but he had faith in her abilities as a mechanic and engineer, and as the creator of the Ironman suit and a genius. He had faith that she wouldn't do anything stupid.

But he had been wrong, and he swore that his heart was in his throat and his lungs stopped working as the power falters in the suit and she begins plummeting towards the earth.

"Come on, come on!" someone whispers, and it takes him a moment to realize it's him. Hank looks just as panicked as he feels, and a brief thought flashes into his head about why no one thought of the ability to fly when they made the super soldier serum. Hank is typing rapidly into the computer, Jarvis is trying to reroute the power to the original settings, and all Steve can do is grip onto the desk with white knuckles, feeling incredibly helpless as he watches the love of his live is falling a thousand feet per second towards her death. He isn't even outside, he thinks somewhere in the part of his brain that isn't filling with adrenaline, he's watching her on a computer screen and she's going to die all alone while he knows the exact speed that she's falling and the exact coordinates of impact and the amount of pressure on her body and so many other things that he doesn't want to know because she's dying.

"Come on, Toni!" He roars, just as Jarvis finishes his adjustments and her suit thrums to life, and she swoops up and away from the ground that is just feet below her. Five and a half feet, the screens tell him, and with a sickening jolt Steve realizes it's her exact height. Another Toni length and she would have been Ironpancake, not Ironman or Ironwoman, whichever she's going by now, or a living breathing human that he didn't know if he could survive without anymore.

A crackle of static echos from the speakers, and then it clears and he can hear her whooping with joy. "That was fun, guys!" She cheers. "Let's do that again!"

Steve storms from the room, and he is miles away from her when he realizes she will never change, no matter how much he wishes she would, and he shouldn't try to make her. His motorcycle roars beneath him, and he presses it all the way from Malibu to Manhattan before he calms down enough to return to the Avengers Mansion and place a phone call to Hank to tell them he is alright.

Being in love with Antonia Stark is one of the hardest things he's ever done, but somehow Steve hasn't regretted a moment yet.
