The Werther Project
Sam meets with Rowena in hopes of translating the Book of the Damned. Rowena agrees in exchange for Sam killing Crowley for her and reveals that she can’t actually read the book, only a dead witch named Nadia could. However, Nadia left behind a decrypting codex, which the Men of Letters took when they killed her. Sam begins a search for the codex and discovers Magnus (Kavan Smith) had hidden it within the Werther Box, a vault that caused whoever tried to open it to kill themselves. Sam tracks the box to St. Louis, Missouri, where he is joined by Dean after attempting to leave him behind. After being barred by Suzie (a woman whose family died in the 70’s after she tried to open the box herself), Sam sneaks into the house with Dean’s help and tries to disarm the system with a spell. However, he is unsuccessful and unleashes a spell that traps Sam, Dean, and Suzie in hallucinations which try to get them to kill themselves. Suzie does, while Sam is saved by Rowena, whom he teams up with to disarm the box. Sam learns that the only way is for a Man of Letters to spill all of their blood onto the box, which he starts to do to save Dean. At the same time, Dean hallucinates that he is in Purgatory with his old friend Benny (Ty Olsson) who encourages him to kill himself to keep Sam and Castiel from having to do it later. Dean nearly does, but he knows the Mark won’t allow him to kill himself and also, he sees through the illusion as the real Benny would never want him to do it, so he kills “Benny”, freeing himself from the spell. It is revealed that Sam had been hallucinating Rowena’s presence as Dean stops Sam from killing himself and sheds his own blood into the box, breaking the spell and opening it. Sam and Dean get the codex and Dean destroys the box to be sure it’s no longer a threat. Sam takes the codex to the real Rowena, but chains her to make sure she only uses the book to get rid of the Mark of Cain.
