The Ghost Next Door (1) (S04E03)

Hannah's neighborhood has taken a strange turn with the arrival of a new boy next door. But when exactly did he move in? The house seemed vacant just last night when she went to bed. It still appears to be abandoned, and her attempts to learn more from the neighbor yield no results. He vanishes in the most peculiar manners, and his complexion is eerily pale. Is Hannah dealing with a haunting from... the ghost next door???
