I'm looking for a fix I read a few months ago but can't seem to find again.
It's Clint/Coulson pre-slash (might end as slash) in which they are on a mission in South America somewhere and after the mission goes south, they have to find their way out of the country to a SHIELD rendezvous.
Clint is injured and Coulson steals a jeep which ends up crashing(?) as they feel the country. Clint is pretty badly injured and tells Coulson to leave him repeatedly though out, and at some point Coulson is captured and Clint rescues him (from a train?)
Sorry I couldn't remember more detail, if anyone recognises this (or anything similar) that'd be amazing :)
