So, I know that the story is either a very long one-short or a story with a fee chapters in it, I think its the latter one.
The story is about that Tony and Clint went to Afghanistan for a mission, Clint had gotten hurt by some people and Tony agreed to surrender to them and leave the suit to protect Clint. Both of them are in the same cell (thing) in a cave and to keep Clint safe, Tony made a deal with them to torture him if they left Clint alone.
I also know that Tony would make sign language letters when the kidnappers would take a photo of Tony after his torture and sent the photos to SHIELD.
I think that the person that did kidnap the pair was related to Raza and wanted revenge? Not a hundred percent sure on that.
I do know that Tony managed to save both him and clint and they were picked up by SHIELD in the desert before taken to hospital but then the person that kidnapped clint and tony followed and managed to sneak into the hospital room where tony and clint were to kill Tony but was killed themselves by either clint or someone else from the team or a SHIELD agent
