Ophelia confronts Blackwell after learning he is Salemaestrus Erasmus Blackwell, Prince of the Devils. Blackwell tells Ophelia she reached the final level too early to claim the Devil’s Grant because other contestants are still alive elsewhere in Phantasma, so her only options are a reduced blood-bargain payment or disqualification. When Ophelia accuses him of deception, Blackwell explains that his father bound him to Phantasma as punishment, wiped his memories at the start of each new game, and only restores his true identity when a contestant reaches this final level. Because of that curse, Blackwell has repeatedly chosen contestants to help him search for the hidden key that could free him.

Blackwell also explains why Sinclair spoke of the Phantom and the Devil as if they were separate beings: Blackwell’s father forced that separation to preserve the punishment, and Sinclair was made responsible for keeping Blackwell trapped. Poe the cat was part of that arrangement as well. Ophelia realizes that Sinclair’s unusual efforts to block her came from recognizing that she might truly be able to free Blackwell, and she admits that what she felt between them was real. Blackwell confirms that his feelings for Ophelia were real too, even if his damaged memories left him only partially aware of himself.

As Ophelia thinks through her mother’s warnings and the strange behavior of her enchanted necklace, she realizes that Blackwell’s missing “heart and key” may be one object: her heart-shaped locket, which is magically linked to her own heartbeat. She remembers that when Cade tore it off, her heart nearly stopped, proving the locket is not merely jewelry. Concluding that she herself has carried Blackwell’s means of freedom all along, Ophelia gives the locket to Blackwell and openly declares her love, deciding that freeing him matters more than the risk to herself.

The confession immediately triggers Phantasma’s curse. Ophelia collapses in pain as the locket opens, releases Grimm Blue magic, and restores Blackwell’s full powers, untethering him from the manor. Refusing to lose her, Blackwell uses Ophelia’s owed payment to give her a new working heart, but he cannot erase the deeper curse without a bargain strong enough to counter his father’s magic. He offers one terrible option: if Ophelia signs over her soul, he can cleanse it and return it, but Ophelia refuses because the risk of losing her soul and afterlife is too great.

Blackwell then reveals a second possibility. With Phantasma collapsing now that his bond to it is broken, he needs a new permanent tether to remain in the mortal plane, and Ophelia could fill that role without surrendering her soul. If she agrees, Ophelia would become immortal, her life force would sustain Blackwell’s magic forever, and she would be bound to him eternally, though Blackwell insists she would still be free to choose her own life. As Blackwell confesses the full depth of his love and warns her about the burden of eternity, Ophelia faces the chapter’s final decision: whether to walk away and lose him or bind herself to him forever.
