It's taken nearly four years for Ryan Murphy to confirm what's been on every American Horror Story fan's mind: All the show's seasons are indeed connected, Murphy confirmed in an interview this week with Entertainment Weekly.

Asked about the possible ties, Murphy said:

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.

Fans began speculating about links between seasons once it was revealed they would follow different storylines, characters and time periods. "There's definitely a rhyme or a reason and a connectedness to all of these seasons," he said, "but in the same way, they're stand-alones."

Describing the show as a dramatic "Rubik's Cube," Murphy also revealed how viewers will make the first few connections between seasons in an upcoming episode that brings back Sister Mary Eunice, Lily Rabe's character from Season Two:

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.”

Fifteen more years of American Horror Story? Bring it on.
