The fans of FOX’s horror-comedy mystery series “Scream Queens” will find out who the remaining Red Devil killer is in the two-hour finale episode on Tuesday night, Dec. 8. “Scream Queens” series creator Ryan Murphy suggested that the fans should watch again the pilot episode to determine the identity of the mysterious masked killer, which cast member Keke Palmer teases as “really obvious.”

Spoiler Alert: This feature contains major “Scream Queens” spoilers.

Palmer, who portrays Kappa Kappa Tau (KKT) sorority co-president Zayday Williams in “Scream Queens,” shared in an interview with InStyle that Murphy stated in the beginning that the identity of the Red Devil killer was obvious. “So he made us believe that it wasn't obvious, but it honestly was really obvious,” the 22-year-old actress teased.

Palmer also added that she is excited to see what the “Scream Queens” viewers will think after watching the finale episode. “Scream Queens” has revealed that there are three killers working together on a revenge plan for the bathtub incident that happened at the KKT sorority house back in 1995.

Gigi Caldwell (Nasim Pedrad) served as the mastermind and the bathtub twins emerged as the Red Devil killers. Boone Clemens (Nick Jonas) was one of the masked killers.

The remaining masked killer decided to accomplish the revenge plan on her own. The Red Devil killer has stabbed her twin brother, Boone, and decapitated Gigi in the ninth episode and tenth episode, respectively.

Meanwhile, series creator Ryan Murphy told The Hollywood Reporter (THR) in July that the viewers must go back to the pilot episode of “Scream Queens” and really watch it because there was a big clue dropped as to who the Red Devil killer is. Murphy teased that the viewers have met the killer in the first episode of Fox’s new TV series.

Murphy also revealed to THR that four characters out of 25 will be left at the end of “Scream Queens” Season 1. Murphy further added that the four surviving characters will continue to a new horror genre when and if “Scream Queens” Season 2 is ordered.

“Like a sorority is a horror genre to me, it's a place where there were horror movies in the '80s like Sorority Row — and they will go on. That's the format of the show,” Murphy shared. “Scream Queens” Season 1 airs on Tuesday nights at 9/8c on FOX.
