Social Justice Jedi
One of the things I hated about the otherwise excellent Agent Carter series was how white they portrayed New York City as being. Shows that depict NYC as a lily-white town are a special peeve of mine. So my headcanon about that show is that somewhere uptown, there's another office of the Strategic Scientific Reserve — or some other proto-SHIELD organization — located near Harlem, staffed by Black and Latinx agents who struggle with an even skimpier budget than Carter and her buddies, but also work with less scrutiny. I'd like to see what they're up to.
