'Scream Queens' season 2 episode 4 spoilers: Will next episode lead to another Halloween massacre?

Halloween is about to hit C.U.R.E. Institute Hospital and a grieving Chanel Oberlin (Emma Roberts) will literally turn blue in next week's episode of "Scream Queens."

Following the shocking death of Chad Radwell (Glen Powell) mere minutes from his fast-tracked marriage to Chanel, everybody at the institute falls into grieving, but only for a while. The Green Meanie is still out there, after all, and putting a stop to his/her crimes always takes top priority.

In next week's episode of FOX's horror comedy series, Dr. Cathy Munsch (Jamie Lee Curtis), Special Agent Denise Hemphill (Niecy Nash), and Hester will come up with a timely plan to stop the Green Meanie dead on his/her tracks once and for all.

Since the hospital building in which C.U.R.E. now operates has made quite a reputation for the Halloween Massacre that happened in it in the past, what better way to lure the killer out than to throw a Halloween party?

In the preview for episode 4 titled "Halloween Blues," Chanel is shown to have turned blue for some reason. It's no wonder that she ends up going to the party dressed as a Smurf.

But what could've caused her skin to turn blue? Did Hester's comment about her skin looking dry affect her so much that she tried to self-medicate? Will this make her C.U.R.E.'s patient in the upcoming episode? And knowing what happens to every patient that ever comes through C.U.R.E.'s doors, will the Green Meanie come after her, or is the killer saving her for last?

In episode 2, Nurse Ingrid Hoffel (Kirstie Alley) asked Zayday to keep close tabs on the Chanels' activities, which led to speculations that she could either be the killer's mother or is the killer herself.

In this week's episode, Zayday survived being gutted when the Green Meanie, strangely enough, turned and ran away upon seeing her. Was the killer repelled by Zayday's courage, or could Zayday be involved with this season's killer in some way?

According to a brief synopsis on TV Guide, another death is to be expected when "Scream Queens" returns next week for episode 4 on Tuesday, Oct. 18, at 9 p.m. EDT on FOX.
