I tried to find this one myself but to no avail.
Clint and Steve are stranded together in the wilderness when a decision by Clint brings down their Quinjet? I remember that Steve is injured, and Clint has to tend to him, and that Clint is hiding a series leg wound and their roles are later reversed. Part way through the story, they are taken in by a village and Steve is later captured and Bruce poses as a potential buyer?
I really want to re-read this, and any other suggested Steve/Clint friendship fics!
