Lydia Martin: [to Valack] What does the book do?
Stiles Stilinski: Tell us.
Dr. Gabriel Valack: I told you. It opens your eyes.
Lydia Martin: How?
Dr. Gabriel Valack: It triggers the memory centers of the brain, clearing the fog and bringing the images of the Dread Doctors into focus. I wrote the book in an effort to find out if anyone else like me had ever seen them before. I thought I could circulate it, an effort to trigger someone's, anyone else's memory. They'd see the cover, a hint of memory. They pick up the book, read it. The suppressed memories surface, and they'd find their way to me to discover more. Just like you did.
Stiles Stilinski: Did it work with anyone else?
Dr. Gabriel Valack: You didn't see it on The New York Times' Best Seller list, did you?
