IMO, there is a good chance that Teal is a person with Dissociative Identity Disorder (DID). She would have the right background and it is not unknown for people with DID to believe alters are outside spiritual entities and set up as psychics. It can explain how and why her story shifts. Madame Blavatskay was like this too.
Some persons with DID have very sociopathic alters. Some of them are quite borderline. Teal sounds like someone like that. Notice that she has not sought out therapy herself. She's probably a survivor of some sort of terrible abuse, but her stories are mostly exaggerated. And not all abuse survivors are good people.
