Stolen Lullabies

It has been a long, long time since the Russians' reluctant allies had to fear a shadow with flaming hair showing them to their place. A long, long time since that shadow has lived in her fatherland. She still wears the clothes she did then. Still moves the way the taught her; no weaknesses in sight. Her head may not be governed anymore, but her knives still do not belong to herself now.
The men that used to buy her protection with money dripping with blood now fear the whispers of her.
And she thinks that she is the only legacy of the ugly, writhing, violent place that birthed her. That made her into a shadow. Thinks that the only proof left of it are scars. She doesn't know that in the most important moment, she failed. Natasha Romanoff does not know the people who gave her the name Natalia still live and breathe.
And what she especially doesn't know is that there's a young girl who's been in this world for not such a long time with hair not un-like the fire that burns down houses.
Doesn't know of the new whispers inside the Red Room. The comparisons. Like her, they say. This girl? She will do it all. If they could see you, Natasha, they'd tell you that she's capable of the things you dream of at night.
The perfect secret.
But when intel doesn't move as fast as expected -- or, rather, too fast on the wrong side -- suddenly things that weren't bargained for happen. And maybe they're enough to send it crashing down.

All rights belong to MARVEL !! The only things that belong to me are Avanya, more OC's that'll follow and their plot, but not The Red Room. There might be heavy stuff like death, blood, violence, etc. (I don't think I'll include any rape-like things from The Red Room), but I'll put that in the chapters it applies to and a summary at the end of the chapter.
