I'm pretty sure that Violet said Croatoan in season 1 to try and get rid of the spirits in the house. Croatoan was the ritualistic thing to get rid of the vengeful spirits on the land. What if their connected???!!!
Evans acting through out the episode which he appeared in quite a bit, I have to say was phenomenal. I mean you know this guy plays in every season of AHS but this one was truly character that was completely unexpected and amazingly portrayed!!
