Unfortunately for Ben, the ghosts have other plans for him. When he tries to leave, the evil ghosts of the house, led by Hayden, murder him and stage it to look like a suicide. Hayden tries to take the baby, but Constance gets there first and hides the baby away, telling the police that Ben killed himself in grief and that Violet fled with her newborn brother.
The Harmons, reunited as ghosts, decide to work with the benevolent ghosts to scare off any future tenants in order to protect them from suffering similar gruesome fates. The family blocks out the ghosts of Hayden and Tate, and try to live as "normal" a life as they can.
Even with half the cast dead, this would be a relatively hopeful ending, so of course there has to be a twist. Three years later, Constance returns home to find that her grandson Michael (Tate and Vivien's son) has murdered his nanny, hinting that the prophecy that he would be the Antichrist is starting to be fulfilled.
Rumors are flying about the roles that these Murder House characters, particularly Vivien, Ben, and Michael, will be playing in the upcoming Apocalypse — it won't be long before we find out just what Ryan Murphy and co. have in store!
