Ryan Murphy's horror comedy Scream Queens is technically an anthology series, but it seems to have a somewhat more linear narrative than American Horror Story (which starts over from scratch each season). This means it's time to revisit all the drama that went down at Wallace University's Kappa Kappa Tau sorority house, so when the show returns Sept. 20, you won't be as clueless as Boone that time he got stabbed to death by his own partner in crime.

So Who Was the Red Devil?

Despite the fact that Hester was kind of the obvious choice all along, leading many people to think she couldn't have been the Red Devil, Hester (Lea Michele) in fact ended up being the Red Devil. Hester and her twin brother Boone (Nick Jonas) were the babies born to that KKT sorority girl who died in the bathtub in 1995. Another KKT sorority girl named Amy Meyer took them, but killed herself. Amy's sister Jess (Nasim Pedrad), later known as KKT national president Gigi Caldwell, then took the babies and raised them as murderers to avenge the death of Amy. You got all that?

But She Got Away With It

Hester framed the Chanels for the Red Devil murders, as part of her grand plan to take down Kappa Kappa Tau. Chanel (Emma Roberts), Chanel #3 (Billie Lourd), and Chanel #5 (Abigail Breslin) were sentenced to a mental hospital, where they all end up weirdly happy — Chanel because she's finally learned to be nice, Chanel #3 because she's embraced her interest in women, and Chanel #5 because of medication. But just as she really got settled, Chanel woke up in the night to find a knife-wielding Red Devil hanging out by her bed. Hester, is that you?!

And Who's Still Alive?

Pretty much everyone, except Gigi, Boone, Pete (Diego Boneta), Earl Grey (Lucien Laviscount), and Chanel #2 (Ariana Grande). As previously mentioned, the Chanels are in the hospital, leaving Zayday (Keke Palmer) and Grace (Skyler Samuels) to remake KKT as a kinder, gentler, less murdery sorority. Dean Munsch (Jamie Lee Curtis) also made it out alive, despite being the one person actually culpable for the death of Boone and Hester's mother; she ended the season as a best-selling author. Denise Hemphill (Niecy Nash) set off for FBI training after enjoying a star-crossed romance with Chad Radwell (Glen Powell), and Grace's dad (Oliver Hudson) went on vacation with his new girlfriend Dean Munsch. It is honestly unbelievable that someone thought it was OK to kill off Earl Grey and leave Grace and her dad alive, but OK.

And What's Up With This Hospital?

This hospital is apparently not the same one that the Chanels were sent to at the end of season one, but it is owned by Dean Munsch. The Chanels are medical students, which is crazy for many reasons like, "There is zero evidence that they do any schoolwork, ever, and also they're insane." Lord help anyone unlucky enough to be in their care, because the only person on this show likely to provide you with worse treatment is the serial killer. John Stamos and Taylor Lautner will also play employees at this mysterious hospital, and judging by one of the teasers, Taylor is going to have some sort of fling with Chanel #5. After all, how could she possibly resist a man named Cassidy Cascade?
