I'm looking for a story where Darcy joins SHIELD and ends up working in the archives at first. There she ends up filing away all of Phil Coulson's stuff. A bit later she finds him in the infirmary (I think she was taking Jane there, after finding her in rough shape?). The pairing may have been Bruce/Darcy later in the story. There was also something about Darcy being really independent and getting an apartment in a not-great neighborhood after speaking to a waitress. And I think Darcy got a dog?
Also, could there be a theme tag for Coulson Lives?
