Jamie is a psychic who is an acquaintance one of Cody's friends to tag along with them while they explore a haunted house together  (Medium range but feel free to interpet the lines in your preferred tone)

*(It's hard to phrase this/find a proper fitting word but I assume most of you have seen or vaguely aware of that one tone psychic charas use when attempting to talk to ghosts and such [tho the tone may change based on the director's preferences])
