Last night's Scream Queens revealed a key element of Wallace University's murder mystery: Boone (Nick Jonas) is one of the red devil killers! The "Ghost Stories" episode starts with Boone in disguise walking around campus, until Billie Lourd's Chanel No. 3 spots him in the park. Just when he thinks he's been caught red handed, No. 3 assumes he's a ghost and he's off the hook.
She reports back to the Kappa house with her ghost sighting, but not before Chanel Oberlin (Emma Roberts) tells them that Chad gave her a turkey wishbone necklace and asked her to spend Thanksgiving at the Radwell family compound in the Hamptons. This is a big deal for Chanel and her quest to find a rich, hot husband, but back to the ghost sighting: No. 3 reveals that she saw the ghost of Boone and is having a hard time coping. Security guard Denise Hemphill (Niecy Nash) decides to tell them ghost stories around the fire to keep their minds off all the scary stuff happening in real life.
After Denise tells her stories (and barely escapes a red devil attack during a bathroom break), Hester, aka Lea Michele's Chanel No. 6, tells her own ghost story: a young woman drives late at night in the 1950s and hears on the radio that a man has escaped from a mental institute. In that same moment, a truck behind her is repeatedly flashing headlights at her car, until she pulls into a gas station to find help. When she gets out, the truck driver says he's not trying to hurt her but that there is someone in her backseat who is. Every time the man in her backseat would pop his head up to stab her, the truck driver flashed his lights so the man wouldn't be able to see. They quickly check the backseat but by that point, the man is already gone.
Meanwhile, Boone visits Chad at the Dollar Scholars frat house. Chad assumes that Boone is a ghost and catches him up on all the campus happenings. Boone asks him about Zayday (Keke Palmer) and says he wants to take her out on a proper date. Chad, confused about Boone's changing sexuality, breaks it to him that Zayday is now with Earl Grey (Lucien Laviscount), another member of their fraternity.
In that same moment, Earl Grey is actually in Zayday's room at Kappa house and the two are ready to take it to the next level. He runs back to the frat house to get the proper materials needed, while Boone sneaks into the room through the window. Boone tells Zayday that he's actually a ghost, but still wants to take her on a date. Only one problem: She doesn't believe in ghosts. Grace walks into the room and the two immediately conclude that Boone faked his own death so he wouldn't be suspected as the killer in the red devil costume. He even had a scar on his hand from when Zayday stabbed him with a fork upon her escape from his evil lair. They shove him, he falls out of the open window, and disappears. But not before he stabs Earl Grey, who was on his way back to Zayday's room, to death.
At this point, Chanel No. 5 (Abigail Breslin) can't take any more deaths and leaves for good. But on her drive, No. 6's ghost story comes to fruition! But this time, the man in her backseat is actually Boone in the red devil costume and he ends up stabbing the helpless fool who tried to help her.
Back at the Kappa house, Chanel is dealing with something far greater than the red devil's killing spree. Chanel No. 6 tells everyone that she is pregnant with Chad Radwell's baby and that she'll be attending his family Thanksgiving in Chanel's place. Chanel is horrified and confronts Chad, who tells her that Radwells go down with the ship, so he plans on marrying her too. Livid, Chanel decides that the only course of action is to kill Hester and enlists her original minions to help her.
The detective finally shows up at Kappa house and decides that there must be paranormal activity causing all these murders, what with Boone's ghost being spotted several times. Zayday and Grace cannot believe that the detective is so incompetent, when clearly Boone is alive and faked his death. They're also mad at Dean Munsch (Jamie Lee Curtis), who is meeting with the detective as well, for being so unhelpful. The dean actually agrees and fires the detective on the spot. In an effort to be more helpful, she gives Zayday and Grace another piece of key information: There were two babies that night in the bathtub, a girl and boy. They all assume that Boone is the boy, but as for the girl? We'll find out soon enough!
Boone and the other red devil meet up with Gigi. She lectures Boone about going out in public with a bad disguise and he quickly turns the blame on her for their hard lives. The other red devil is close by them with a drawn knife and just when you think that she is going to stab Gigi, she stabs Boone in the heart. One red devil down, another to go!
Back in Chanel's epic closet, the girls have devised a plan to trick No. 6. They offer her sushi, unpasteurized cheese, and Champagne, all of which she takes and enjoys happily. Aha! They accuse her of not really being pregnant since she ate and drank all of those pregnancy no-no's. She admits that she's not but now that she's going to the Radwell Thanksgiving, she has plenty of time to make it happen.
She runs off, but Chanel stops her abruptly at the top of the marble staircase and apologizes profusely for her being an outcast. She lays it on thick with the compliments and apologies until she pushes her down the stairs! No. 6 falls, bedazzled neck brace and all, until she hits the bottom and dies.
There are only a few episodes of Scream Queens left so tune in to Fox next Tuesday at 9 p.m. ET.
