American Horror Story: Roanoke is being told through the frame of a paranormal docu-series called My Roanoke Nightmare, which means that there's a potential to break the fourth wall this season. So far, all we've seen from the the "real-life" Shelby (Lily Rabe) and Matt (André Holland) are their studio interviews, and while those are compelling in their own way, we've basically been counting down to the moment creator Ryan Murphy lets Rabe snap. After all, she's delivered so many of the show's most bombastic performances, so it seems like a missed opportunity for AHS to use her in such a limited capacity this season.
However, that may start to change. In the promo for next week's episode ("Chapter 3"), Matt's sister Lee (Adina Porter) freaks out during her studio interview and screams, "You need to turn off those cameras! I said turn off those cameras!" While that's pretty normal behavior from someone who's retelling traumatic events, it could also lead to more behind-the-scenes developments if the show decides to break the fourth wall and inevitably drag Shelby, Matt, and Lee back into their Roanoke nightmare.
Another popular theory suggests that the "actors" portraying Shelby (Sarah Paulson), Matt (Cuba Gooding Jr.), and Lee (Angela Bassett) in the dramatic reenactments are filming on location at the "Murder House." It's possible that when the cameras stop rolling the actors themselves could start to be haunted by the Roanoke spirits.
However, I'd like to believe that this entire docu-series is nothing more than Billie Dean Howard's attempt at a cash-grab. What if the stories Shelby, Matt, and Lee are telling are fictional ghost tales written by Howard herself? Maybe she even used Vivian and Ben as her inspiration for Shelby and Matt. Given the similarities between Murder House and Roanoke, I honestly wouldn't be surprised.
