goddamn it, I'm gonna hurt you." That night, Frank returns to Susan's hotel room and, assuming that Susan is the form he sees the bed, starts talking to her. The person under the blanket turns out to be not Susan but brother Duane, who leaps up and attacks Frank, attempting to strangle him. Frank takes scissors from a nearby desk and stabs Duane in the hand, impaling him and embedding the scissors. Frank flees, stopping off at a bar to calm down.
