It was about Clint, who was an indentured servant or slave of some kind to SHIELD, and was being blackmailed into it by Phil, who was the only one to know Clint had a daughter.
I think in the beginning he was forced to have a tattoo removed of a bird or something, and it had a ton of sentimental value about his daughter.
He also was rescued later on somehow by the rest of the Avengers I think.
Im prettt sure the fic was rather lengthy.
Thank you, I've been looking for it for like the whole day and I don't know it it was taken down, or I'm looking in the wrong places, or what.
