   Summary

   What if Natalia Romanova, the infamous Black Widow, was born a twin?

   Zinaida Romanova doesn't think she's anything like her sister. She isn't effervescent like her, she doesn't wonder or even, really, care why they do what they do. In fact, it is this ignorant expertise that gets her noticed by the wrong person, and consequently, sent off from the only home she's ever known to a bunker in Siberia where she meets the Winter Soldier.
