How did Cyrus and Dennis trap the ghosts?
That's what I want to know.
So I take it some of these ghosts were wandering Earth for quite a while, given the Pilgrim woman. It would seem all of the ghosts except for the mother might have a reason to be unsettled spirits. But since Kalina mentioned that the fourth ghost (the mother) was from "six months ago at St. Luke's Hospital," that makes me think that somehow Cyrus and Dennis trapped her spirit while she was dying -- that they were there? I dunno.
