After spending five episodes watching the faux docu-series My Roanoke Nightmare, American Horror Story: Roanoke drastically changed directions in Episode 6, revealing the behind-the-scenes production of a new show within a show, Return to Roanoke: Three Days in Hell.

The reality spin-off features the real Shelby (Lily Rabe), Matt (Andre Holland) and Lee (Adina Porter) returning to the Shaker mansion along with a handful of the reenactment actors who starred in My Roanoke Nightmare (Sarah Paulson, Evan Peters, Angela Bassett and Cuba Gooding Jr.). With the mansion now decked out with hidden cameras, the plan of the show's producer Sidney (Cheyenne Jackson) is to capture the cast being terrorized by fake hauntings set up by his crew. However, production of Return to Roanoke: Three Days in Hell overlaps with the Blood Moon, and almost immediately the cast begin to get picked off one-by-one by the real-life ghosts.

But now that the fourth wall is broken, who will play these nefarious spirits? We have a few ideas!

The Butcher
Kathy Bates stole the show as the blood-thirsty Butcher in the first half of the season, leaving massive shoes to fill for whoever takes on the role next. Fortunately, the AHS universe is filled with talented actresses who are more than up to the task. Either Mare Winningham or Patti LuPone would be incredible as Thomasin White, but our personal pick for the part would be Winningham. She was a standout in Hotel as Mr. March's devoted maid, and we would kill to hear her take on the Butcher's unforgettable accent.

Priscilla
In "Chapter 6" it appears as though Diana saw Priscilla before being attacked by Piggy Man. If that really was her, then the actual Priscilla is much older than the actress who played her in the reenactments, which would put Taissa Farmiga in the running for this part.

We originally fell in love with Farmiga on Horror Story as a lovable (albeit angsty) ghost, so this would be a fun way to bring her back into the fold for the first time since Coven. Otherwise, we'd welcome the chance to see Jamie Brewer as the young spirit who maybe isn't as benevolent as she initially seemed.

Edward Phillippe Mott
Finn Wittrock, who played Edward's descendant Dandy Mott in Freak Show, is the most obvious choice for this role. However, creator Ryan Murphy described Wittrock's character in Roanoke as "his most f---ed up character of all time." But what we've seen of Edward so far — or at least Shelby and Matt's version of Edward — doesn't even compare to the messed up things we've already seen Wittrock do as Dandy Mott. So unless the Millers completely fabricated everything we know about Edward, Wittrock doesn't fit the bill.

If Wittrock isn't playing Mott, then our next bet is Matt Bomer. In Hotel, Murphy played on the fact that Wittrock and Bomer look alike, so Roanoke might continue to exploit their resemblance by having Bomer take on the role of Edward Phillippe Mott.

Piggy Man
Assuming Wittrock really isn't playing Edward, there's a good chance we've actually seen him this season already, even without the actor ever showing his face.

When describing Wittrock's character, Murphy said the role is so twisted, even the actor was taken aback. "He was like, 'This is so crazy that I don't know that I can do it, but I'll do it," Murphy recalled. And who is more disturbing than a serial killer who wears the head of a decapitated pig as a mask? Short answer: No one!

Ambrose
We don't know too much about the Butcher's son beyond his penchant for making regrettable choices, so the field of speculation is wide open for this role. Bomer or Wittrock could feasibly play Ambrose, or Murphy might go for a less expected AHS alum, such as Joseph Fiennes, Josh Hamilton or Max Greenfield.

The Jane Sisters
Lizzie Brochere, Alexandra Daddario, Emma Roberts, Taissa Farmiga and Alexandra Breckinridge would all be perfect choices to play the murderous nurses Bridget and Jane. But of the actresses listed above, Farmiga is the only AHS alum confirmed to be returning this season. Meanwhile, Roberts is busy with Scream Queens, Breckinridge welcomed her first child in September, Brochere is starring on the USA drama Falling Water and Daddario was recently filming Baywatch.

However, the Jane sisters aren't exactly major roles in Roanoke so it's still completely possible that any of these actresses could squeeze in the time for a quick and bloody cameo.

Scathach
Now that Murphy confirmed Scathach is the first Supreme, it would be a nice callback if the actress playing the real Witch of the Woods already has ties to Coven. But since the majority of the actresses who played the Coven witches have already appeared in Roanoke, there are only a few options to choose from (including Taissa Farmiga), but the most appealing of which is Jessica Lange.

Lange left American Horror Story after Freak Show, which prompted Murphy to recruit Lady Gaga to fill the massive hole the Oscar-winner left in her wake. In the years since, Lange has been fairly vocal about not returning to American Horror Story, but she is collaborating with Murphy again on another FX anthology series, Feud. Maybe during their current work together, Murphy managed to convince Lange to make one last cameo as Scathach, because who better to play the first Supreme than AHS' original Supreme?

Who do you think will play the Roanoke spirits?
