it's all actually happening. She flees her house and drives away; spotting James entering an old barn, she follows him inside. She is captured and killed by the child preacher, after which children gather at the barn. Grace decides to go to Dr. Larsen's house to find him. Donald hijacks her and her car and forces her to drive at gunpoint. They go to Jane and Rosa's house. Rosa reveals that the child preacher, Josiah, was the bastard son of a local woman. He was taken in by traveling preachers and became a gifted preacher. Over the years, Josiah stopped aging and never grew out of boyhood. The traveling preachers gave him over to darkness to stunt his growth, but when word got out, they abandoned him. Josiah killed the preachers, then the townspeople burned him alive and sealed his remains in a well. Meanwhile, Mary Anne, Grace's best friend and co-worker, is attacked and killed by Josiah. Grace and Donald return to the clinic and discover that Margaret is missing, but they learn that Josiah's weakness is mercury. It is also revealed that Josiah is Rosa's son. Margaret, James, Marcus, and all the other children gather at the barn and offer blood to Josiah. Marcus is a hemophiliac, so he would bleed to death with even a small cut, but he cuts his hand and offers his blood to Josiah, and Margaret offers Josiah her soul. Marcus collapses from blood loss and Margaret is pulled into the pool of blood, from which Josiah emerges. Donald and Grace arrive at the barn and connect its sprinkler system to their supply of mercury. Donald fills two of his bullets with mercury and gives Grace the gun. Donald stops Marcus' bleeding, but the children try to kill him. Josiah attacks Grace, but she shoots him with a mercury bullet. She then finds the bodies of June and Dr. Larson. Josiah attacks her again, but she activates the sprinklers, which shower him with mercury. Grace slashes him with his own scythe, finally killing him. The children stop trying to kill Donald and return to normal. Grace finds Margaret; she's nearly drowned, but Grace manages to revive her. It is revealed that Margaret is actually Grace's daughter, and that she abandoned her with June as a teenager. After the victims' funerals, Grace, Margaret, James, Donald, and Marcus all move out of Nebraska. Cast Production
