Found Jensen/Cougar fic!
I cannot find this title for the life of me! I remember it started out with Jensen carrying Roque on his back and Cougar was leading the way in a desert setting and along the way Jensen collapsed from an injury. They end up in this cave and Cougar has to care for both Roque and Jensen. They need to get to the border of somewhere so Jensen still needs to carry Roque on his back and he just gets worse and worse along the way. They eventually make it and thr others pick them up. Please help its drving me crazy that I cant find this thing!
