I have seen Darcy! She seems snarky competant and smart and pwns with science. I think I read one where she is with Loki and it was awesome? I got confused about Darcy early on, confusing her with XMFC (I think?) when I'd been told there was an awesome female character who got killed off in a red-shirt way to prove that the situation is so dangerous we'll kill a woman, so somewhere I got confused, and got the idea that Darcy died, oops.

And being Coulson/Clint does not mean that Darcy cannot be awesome in it. Like this one.

Do you have recs? I try to avoid really canon-heavy fics that require canon knowledge, which I do not have, but I've found that if the deep-in-the-guts-of-canon fic is well-written enough, you don't need to know more than the absolute basics about canon to follow along. (Those types of fics are also the sort where you go: why can't canon be as good as the fic? and weep.)
