When a dragon attacks Manhattan, Clint is hit by a curse, and both he and Bucky have to face that this might be the end of his time as an Avenger. Neither of them cope well.
But at least it gives Clint an excuse to get a dog, right?
The curse effects are horrible to imagine, especially at first, and there's lots of relationship angst, but there *is* a happy ending. Well-thought-out and creative.
