Credence and Graves have been married for a while, and some of Graves enemies figure this out, even though Graves tried to keep it as quiet as possible. They kidnap Credence, Graves finds them, and they rape Credence in front of Graves. Graves gets free of his bindings and manages to stop them, and tortures them all until Credence begs him to stop.
