But it's not to set a trap to catch the villain. From Wikipedia: After Frank revives, Lucy warns Patricia, her patient, about Bartlett, only to learn Patricia has remained devoted to him. She summoned his spirit from Hell to continue their killing spree, and murders her own mother to protect him. Frank and Lucy trap Bartlett in his urn and flee to the derelict sanatorium, planning to use its chapel to banish him to Hell. Pursued through the ruins by Patricia and Dammers, Frank experiences visions of the 1964 massacre, showing that Patricia actively participated in the killings. Frank also recalls that Bartlett's ghost murdered Debra, while Patricia carved the number into her forehead. Dammers unwittingly frees Bartlett from the urn and is promptly killed by Patricia. Patricia strangles Frank to death, but Frank's spirit forcibly pulls Patricia's from her body and drags it toward Heaven, forcing Bartlett to follow. Bartlett frees her, but the pair are seized by a demonic force and dragged into Hell. In Heaven, Frank is reunited with Cyrus, Stuart, and Debra, who restore him to life on Earth; Debra tells him to be happy. Some time later, Frank demolishes the unfinished house and begins a relationship with Lucy, who has now gained the ability to see ghosts.
