Oh, Misty Day. The enchanting Steve Nicks-obsessed character — impeccably portrayed by Lily Rabe — is a standout of American Horror Story: Coven. While the show's current eighth season, American Horror Story: Apocalypse, features several fan-favourite witches, it's tough to say whether Misty will be making an appearance given her fate in the third season.
Let's back it up a little. Misty belongs to Miss Robichaux's Academy because she holds the power of resurgence, meaning she is able to bring people back from the dead. After her power is discovered by her highly religious community, Misty is burned at the stake. Fortunately, she is able to bring herself back to life and she finds protection among the other witches at the academy.
After resurrecting several people in crucial moments, including fellow witches Madison Montgomery and Myrtle Snow, it's believed that Misty might be the coven's next Supreme. The coven then pressures existing Supreme Fiona Goode to participate in the Sacred Taking ritual, which would entail committing suicide to make way for the incoming Supreme. The plan is unsuccessful as Fiona miraculously survives a drug overdose.
As the mystery surrounding who might be the next Supreme intensifies, Madison backstabs Misty and buries her alive in a cemetery. (Casual.) Fiona's daughter, Cordelia Goode, decides to put an end to the in-fighting and tests the witches on their ability to complete the Seven Wonders, or powers a Supreme should posses. Along with fellow witches Madison, Zoe, and Queenie, Misty passes the first two tests of telekinesis and concilium, or mind control.
In the third test, the witches must perform descensum, or the ability to descend into hell, or their own personal perception of hell, and safely return to reality. As a pacifist and lover of animals, Misty's hell is her biology class, where she's forced to repeatedly dissect a living frog and resurrect it. Tragically, time runs out on the test and Misty is stuck in hell forever, while her physical form disintegrates.
Though Misty didn't make it out of the third season, the same can be said for Madison and Myrtle, who are very much present in Apocalypse. Given the frequent twist and turns the show takes, it's not impossible that the beloved character could be saved from her netherworld — and if anyone were to do it, the Antichrist would be a pretty fitting person, right?
