The sky is empty because the episode is full of stars, from Judith Hoag (the first April O'Neil, Teenage Mutant Ninja Turtles) to Dina Meyer (Birds of Prey, Starship Troopers) to Jay Karnes (TV's Dutch Wagenbach). One or more of them is the mysterious Piano Man, the rapist who uses piano wire and loves piano songs. Who is it? What does it have to do with Prentiss' PTSD?
