She's a Barnes?// AU Bucky Barnes daughter

Isabella June Barnes, better known as the Amethyst Witch, just escaping out of HYDRA but when found by the Avengers things don't go as planned, she doesn't know who her parents are, where she was born, or where her mother is, all because she was chosen by Red Room and HYDRA to become one of the best Assassians off all time so when the Avengers find her she reuses to talk afraid she'll get put through torture again no matter what she does (I DO NOT OWN MARVEL OR ANY OF THEIR CHARACTERS, also TRIGGER WARNING: Bella suffers from anxiety attacks, depression, PTSD and an eating disorder, I know that trigger warning was late but after writing chapter I realized I should put a trigger warning)
