Last week, we reported that American Horror Story: Freak Show is bringing back actress Lily Rabe, who has had roles in all four seasons, as her American Horror Story: Asylum character Sister Mary Eunice in this season's 10th episode. In a new interview with Entertainment Weekly, series creator Ryan Murphy revealed that this season is the first time fans will know that every season is connected in certain ways.

Here's what Ryan Murphy had to say about how Lily Rabe's return as Sister Mary Eunice is the first "unveiling" of the show's "connectedness."

"I don't want to say much about it but obviously she's playing Sister Mary Eunice. The interesting thing about doing a show like this is every season is incredibly its own story and its own beginning, middle and end. Its own journey. But we have always from the very beginning in the intertwining mythologies and how things connect. This is the first year where we begin to tell you that season two is connected to season four which is connected to season one. People have started to write articles about that. A lot of their hypotheses have been completely right on. That's the fun of the show. Hopefully by the end of the run, be it 10 years or 15 years, people will be able to stand back and be able to say, 'Oh that was connected to x.' There's definitely a rhyme or a reason and a connectedness to all of these seasons, but in the same way, they're standalones, which is the fun of it. But it is a puzzle. And Lily coming back and dealing with Pepper is sort of the first unveiling of that connectedness.

When asked to clarify if Season 4, which takes place in 1950s Florida, is connected to Season 1, set in modern-day L.A., the producer had this to say.

"They're all connected. We're just beginning to tell you how they're connected. They're all very separate but there's clues every season that we're now telling you how the different worlds are intertwined. Part of the fun of the show is the Rubik's cube design of it, but, yes, there are purposeful connections, character connections, and similarities and things that connect that we'll continue to connect moving forward."

The show has already been renewed for Season 5, and there are already clues hidden in plain sight about next season. When asked about a scene where Maggie (Emma Roberts) is handed a cup of coffee with a top hat on the cup, Ryan Murphy had this to say.

"That is a big Season 5 clue! It's an arcane clue, but it's very purposeful, and it illuminates something that you'll be like, 'Oh! You dirty b******!'"
