The film blurs the line between what is real and what exists only in Mary's tormented mind. James appears as both a literal threat and a psychological specter, with his Rain Ripper identity emerging through whispers, phone calls, and terrifying visions. This ambiguity keeps the audience uncertain about what is actually happening until the climax.
