SPOILERS! (?)
I wonder if Lacie's 'problem' is similar to Miss Knives. As in- having some kind of demonic aura/entity following her. For Miss Knives, that entity seemed to have been trying to help her, she was just in a period that deemed everything as witchcraft (They technically werent wrong..but cmon, it wasnt hurting anyone...except for trying to protect her.) . So I wonder if Lacie has something similar, except it isnt trying to help her, but rather make her life an inconvenience (?)
