To those new to American Horror Story...
I advise that you watch from Season 1 to the latest for, it has now become customary for this series to have previous characters from early seasons appear in later seasons.
For your convenience, since this is *was* an anthology series which regular actors are supposed to reprise different roles for succeeding different season themes, to find each season very intriguing and with at least further depth, as well as, less confusion and of the feeling as if the producers of this hit TV show were recycling actors and have them portray different roles all at the same time. *coughs* season, I mean.
Like remember when you watched Hotel and thought why did Hypodermic Sally seem to have a twin who is a Psychic-host of her own show?
Or, Why did that British actress whom I was used to call Shelby in a documentary series turned out to have an old doppelganger who happens to be a journalist named Lana Winters?
And, um, oh wait? That actress Sarah Paulson may exaggeratingly play 18 characters in one season according to one of the creators of the show. (Don't mistake me. I love Sarah Paulson so much. Haha. I just wanted for everyone to have a great time and coherent grasp of the show.)
