Y/n Banner is the younger sister of Bruce. She was in the same accident as Bruce, so if she gets too angry? The other her will take over. She’s a masseuse, and one day, she gets a call from Tony. He says they could use her on the team for “physical therapy”. She accepts the offer, but never had she thought that falling in love with Bucky would be included in it. Let alone that he would become her anchor.
