According to Dr. Sparrow, Fred's soul is consumed by the fires of resurrection, which Wesley interprets upon overhearing as soul destruction, seemingly making it impossible for her to return from the dead or enjoy an afterlife, although the specifics of this process are not elaborated. Later, though, Illyria states that there are remnants of Fred in the form of her memories, which are a source of confusion for Illyria. On occasion, Illyria takes on the appearance of Fred in order to go about unnoticed and to deal with Fred's parents. When Wesley dies, Illyria takes on Fred's form to comfort him and because she has Fred's form, the evil warlock Cyvus Vail underestimates her and she easily kills him.
