Clairvoyance, also known as the Sight, is the power to gain information about an object, person, location, or event through means other than the known human senses.
The users of this ability are able to see persons and events that are distant in time or space. Those with clairvoyance usually display the ability to perceive future events, the ability to perceive past events, and the perception of events happening outside of the normal range of knowledge. A being with this ability might be labeled as a "psychic."
Mama Roz described this ability as "to hear what a person needs to know."
In "Kappa Spirit", Macy Vaughn went to visit Mama Roz in order to get answers about a mark on Galvin Burdette. Macy asked about the marking on Galvin, thinking it to be a protection ward which the psychic confirmed. She then warned Macy to stay away from Galvin. When Macy asked why, the psychic told her that she has the "ibi" in her. Mama Roz refused to explain, so Macy offered up more money. The psychic finally admitted that it means that a "darkness" is inside of her. Macy refuted this and began to leave with the psychic telling her to search within, that she is different than her sisters and that "the pillar of your path holds the key to your darkness".
Remembering what the psychic said earlier, Macy later decided to look at one of the pillars of the Vera Manor. Inside, she discovered a box with a key.
In "The Replacement", Galvin, who was at the time possessed by a demon, paid a visit to Mama Roz. While the psychic was able to percieve the demon that had taken him over and warned him to stay away from Macy, he attacked her and killed her.
