Does Elias know about the Supernatural? Did he plant the books to make people think Prairie was lying?
The whole fandom seems to think that he did, but I don’t. This is probably just me being too trusting but I don’t think Elias is the guy we should be really looking at. Yeah he’s dodgy and probably significant but I still don’t know about the books. Prairie signs her name at the bottom of the note, so she must at least know a few English letters. I think she would be able to read the books, and I think if she really is interested in angels then why not buy books about it?
On the other hand, how would she order the books? She has no credit card, not really any access to the internet. She could have taken Nancys card and bought them using the wireless router I guess. I don’t think that they’re proof that her story is fake though.
