Captured

Natasha Romanoff has had a pretty horrible life. Being sent to the Red Room at a young age, killing many innocent people, and watching as the world around her dissolved into chaos. But when she joins the Avengers, she realises she gets another shot at life, changing her name from Natalia to Natasha and successfully avoiding HYDRA along the way. That is, until a friend is captured by HYDRA, and she knows the only way they're getting them back is if she goes back to where it all started. *WRITTEN BEFORE THE BLACK WIDOW MOVIE* WARNING: COURSE LANGUAGE
