That was a weird tie-in. I suppose Elsa Mars isn't the same person as Sister Jude. And Jimmy, of course, wasn't Kit. It was just odd because I've always seen the American Horror seasons as kind of like parallel realities where each has different versions of the same person.
Also, don't really understand the hate towards Maggie. Other than being affiliated with Stanley, I don't recall her committing any evil deeds. I don't feel she deserved that fate.
