Following the destruction at the prom and the death of Carrie's religious fanatic mother Margaret, Sue eventually finds Carrie, unconscious in a bathtub full of bloody water. Sue pulls her out and successfully revives her; Carrie telepathically links with Sue's mind and Sue sees Carrie's entire life (in the book, Carrie sees Sue's entire life, proving her innocence and a little later Carrie later shows Sue her entire life, too). Sue is interrogated by the police, and claims to have found Carrie dead and left her.
Following the destruction at the prom and Margaret's death, Sue finds Carrie, who has been submerged in blood. Sue saves her and brings her back to life; Carrie mentally connects with Sue's mind, allowing Sue to see Carrie's entire past (in the book, it's the other way around). Sue is questioned by the police and falsely claims that she found Carrie dead.
