Fans of American Horror Story's first season will get an added treat in this week's American Horror Story: Asylum episode with the return of Frances Conroy. The actress, who played Moira O'Hara last year, guest stars as, "a dark angel" in "Dark Cousin", airing Wednesday, November 28 at 10 PM ET on FX. The network has released the first photo from the episode, featuring the actress in foreboding black attire, looming over a Briarcliff patient's bed. Lily Rabe's Sister Mary Eunice is also said to be "terrified" of this mysterious character. Judging from this photo, it's hard to blame Sister Mary for being afraid of this devious new character.
