Roth and Contreras are following a lead from the woman who they believe to be Kent's first kill, Vera Bennett. When they reach the library, where she worked for years, they discover that she has a connection to the book, "The Phantom of the Opera" a book which Kent holds near and dear to his heart. 

Kent plans on sharing the book with Betty, in hopes that it will help her to understand that there's more to him that the monster who kills. Betty is turned on by Kent's world, by his killings, but she's completely conflicted about whether or not she can continue a romance with him. 

Betty gets a message on her machine from a man named Jimmy. He's looking for her. He comes to her apartment, angry that she has ended their relationship. She tells him that her new boyfriend wouldn't like the way he's talking to her. She spurs his advances by attempting to break his wrist. He doesn't know what's happened to her...she's changed. 

Vicky wakes up in the middle of the night and finds her father, Roth, reading Phantom. She asks him why he's reading a love story. It's confusing to Jack, as he's never thought of Phantom as a love story. When she describes it to him, he suddenly puts the pieces together. Kent is mimicking the Phantom. 

Kent visits Betty after work, and bring her a copy of Phantom. He wants her to read it, and think of him. He tells her that she is his missing puzzle piece. 

While the Detectives try to figure out the link between Kent and Vera, Betty chooses to look beyond the monster and be with Kent completely, after reading Phantom. 

Kent sends another clue for Karen to follow. Will she keep playing his game?
