For the past three years of your life, you had been a Special Forces soldier. Most of your missions had been kept secret so people didn't find out the harsh conditions you willingly signed up to do, most of it involving killing and harsh things that only the imagination could imagine, and even then, most of it wasn’t far enough. The conditions you performed under were extremely bad and even worse than other special forces teams.
The only problem was that the Avengers had found out that you had interfered one of their missions while you were on your own mission in Sokovia, and when Tony tried to dig into your past so he could blackmail you, all he could find was blurred out pictures of you, and one mission that people could know about. So, to find out more about you and try to find something to blackmail you, they kidnapped you and placed you in a holding cell at Avengers Compound.
Tony, Steve, Natasha and Clint were the only ones who knew about your kidnapping because they were the only ones willing to keep your secret and get secrets out of you. Steve and Clint didn't really hurt you, they just talked to you, while Tony liked to hurt you mentally and Natasha was the only one who liked to hurt you physically.
This morning, Tony came in, right after Steve’s shift of trying to get stuff out of you.
“Are you ready to tell us more about your mission in Sokovia? You know, the one where you interfered with ours?” Tony asked, sitting in front of the chair you were tied on.
