Vanessa converses with the doll and learns that she's speaking with the Devil, who informs her that he cannot take her soul but must be voluntarily given it. Vanessa ultimately resists the temptations and defeats it. Hecate unleashes a transformed Ethan into the room and he kills Evelyn, releasing Victor and Malcolm from their hallucinations. Hecate later sets the house on fire after all the heroes have left.
John Clare is visited by the Putneys in his cage, where they tell him they will change their exhibits from crime scenes to exhibiting "freaks" like he. He immediately breaks free from the cage and brutally kills them both. Immediately after, Lavinia arrives, looking for her parents and asks aloud if Clare's asleep; believing that he is, she calls him a grotesque animal. John Clare leaves to let her find her parents' corpses.
Victor goes to look for Lily in Dorian's home where she reveals that she's been aware all along that she was created by him as well as that both Lily and Dorian are immortal. Lily and Dorian decide to let Victor live with the knowledge of the genocidal monster that he's created.
Back at Malcolm's home, Malcolm ruefully tells Vanessa that he will be taking Sembene's body back to Africa for burial. Vanessa, now knowing that Ethan's a werewolf and because she fears that every action she's taken away from the darkness has led her further into it, asks Ethan to stay with her. However, he turns himself over to Inspector Rusk, who informs Ethan that he's to be extradited back to America.
A despondent Vanessa visits John Clare, who has returned to the underground hospital. He informs her that he's given up on the hope of being able to integrate with humanity but offers to take her with him. She refuses because she believes that everyone close to her becomes cursed, and she doesn't want him to suffer.
Vanessa, now alone, closes the lights in Sir Malcolm's home as Ethan's note is read in a voice over. He thanks her for her affection and understanding, and tells her that while her road is difficult, his is doomed, so they walk alone. However, she takes her cross and burns it, believing herself to be beyond redemption.

- Laser-Guided Karma: The Putneys planned to exploit John Clare by keeping him in a cell for a private freakshow and deride and mock him in the process. He promptly busts out of his cell, snaps Mrs. Putney's neck like a twig, before grabbing her husband and smashing his skull against the wall.
