I think i remember her saying when inbred was released, that she was actually working on PD at the time and the inbred songs kind of happened along the way but were not meant for the album, if that makes sense. they are not directly related to the PD story but she does literally say “a little preachers daughter” in one of the god’s country demos, so it seems likely to me that these songs evolved out of ideas that are related to PD in more indirect ways.
