i'm looking for a post civil war fic. Tony is held at the Raft and tortured by Ross. Team Cap are in Wakanda. TChalla is worried that Tony might give away crucial information, so Steve goes on a submarine to get to Tony. He finds him tied to a chair, hooked up to electrodes and stuck in his own excrement. During the travel on the submarine, Tony is disoriented and ends up trying to kill Steve. That's about all I remember.
Thank you so much for your help!
