I believe this was also the fic that involved Coulson asking Clint out on a first date and does not sleep with him on the first night making Clint think he is not interested. But then Clint is surprised when Coulson asks him on another date shortly after.
Easily Replaceable by pjpuddle chapter 5.
Fic 2. I think the first chapter has Clint hurt from a stab or gunshot wound. He is young/skinny/underfed in this fic and has not joined SHIELD. He manages to crawl into a vent and SHIELD is surprised that he managed to pull himself into one despite being injured. I think they had to pull him out, but i don't remember if he was unconscious or not...sorry that's pretty vague.
