A/N: I love IronWidow, and this popped into my head. Enjoy, review, all that good stuff.

When Natasha finally makes it back to Stark's compound, (she won't call it Avenger's compound again, until he does) she's not surprised to find Tony in his lab. When she steps through the glass doors he glances up at her but doesn't say anything. As he turns his head away again, he nods slightly, letting her know that it's okay for her to come into the room. The bruises on his face have faded but there's an arm sling laying on a workbench and a flexible cast around his hand and lower forearm.

"Hand me the soldering iron will you?" He asks her with a nod towards the table nearest to him. She silently grabs the tool and hands it to him as he passes her a small torque wrench. She stands near him, waiting to see if he'll ask her for anything else.

After about ten minutes, he releases a sigh and steps back from the chunk of metal he'd been working on. He eyes her critically, from her hair down to her toes, and she lets him. She doesn't know what he's looking for, but she hopes he'll find it.

"Your boots and clothes are probably fine but you'll want to get rid of that nice jacket and pull your hair back. No jewelry, either." He tells her as he turns away and heads for a tall cabinet. Looking down at her motorcycle boots, skinny jeans, and black t-shirt, she shrugs slightly. Her green leather jacket is peeled off and placed on a workbench before she uses an elastic band from her wrist to pull her hair into a high ponytail. Any jewelry is quickly removed before she accepts a pair of welding gloves and a mask from Stark.

"The torches can be loud, plus the music, so are you okay with wearing an earpiece?" She nods in answer and he hands her a small device. It's about the size of an earbud. Putting it into her ear, she follows Stark to the back of his work area, surprised when a wall panel slides open and he presses in a code. The wall slides free and before them is a freight elevator.

They step on and for the first time, she wonders what they're going to do. But, she's trying to show him that she trusts him, that she's here for him, even when no one else is. So, she consciously relaxes her shoulders and takes a deep breath, the smell of metal and motor oil taking over her senses.

When the elevator stops, they step into a cavernous room and she can't help but let her jaw drop in amazement. There are three walls of suits. Models, she could tell. In the center was one of the largest and sleekest vehicles she'd ever seen. Or, it would be, when it was fully assembled. Holograms of tanks, jet fighters, and quinjets were pulled up all over the room.

"I started this project when I became Iron Man. I continued it in my free time, hoping to have a ground-to-air vehicle for the team that had no ties to any government or organizations."

"Tony." Natasha spoke for the first time but she had no idea what she could say. "I'm sorry."

"I know. Me, too." He says. "But, that's not all. Getting your sizes wasn't hard, and I already had my blueprints."

She can admit that she's confused at first but then Tony leads her over to one of the walls of suits. And now she can see that they're not all models. Some of them are capable of flight and some even more than that. One in particular stands out. The shape is distinctly female and it's painted all black except for a red hourglass symbol on the stomach.

"It's equipped with Widow's bites, among other things. There's also an AI but I figured you might want to finish the personality details. Since, it's your suit and your AI."

"Why?" She asks him as she lets herself step forward and run a hand lovingly down the armor. "Why do this for me?"

"Because you stayed." He tells her simply.
