I honestly can't remember much about this fic other than this particular scene:
- Clint stakes out coulsons apartment and fires a warning shot through the window instead of killing him
- He also takes out other people who were hired to attack phil in his apartment
- Nick fury turns up too?
- I'm pretty sure Natasha Romanoff also featured as the person who gave clint the job? Or advised him not to take it? Something like that!
- I remember reading it on ao3
It's definitely not Aim by visiblemarket which is a similar fic I found whilst searching!
