I'm looking for a specific Clint/Darcy soulmate fic. I can't remember too much, but what I do remember was that a young Darcy went with some family, I think her grandma and others, to the circus and saw Hawkeye. After the show, the performers had tents set up so the people could talk to them one-on-one. This is where they find out they're soulmates, and I remember her family freaking out, I think, over the age gap. I think the story continued on to the point where Clint is an avenger and he and Darcy meet up after the attack on New York, but I'm not entirely sure, it's been awhile since I read it.
