When Sue arrives she asks Heather where Chris is, Heather lies and says she isn't there. When the blood is poured on Carrie and the shower video is shown, she bursts into laughter along with the rest of the Ultras and the students. However, Heather also quickly notices when Carrie's blood begins floating and begins to worry and attempts to flee with Brian, pulling him towards the door. When he refuses to leave, she lets go and continues towards the door.
