He later plays a secondary role in "Curse of Darkness", where he is investigating the rise of Dracula in the region. He confronts the Devil Forgemaster Hector, and although he initially treats Hector with contempt, he aids him in his quest. After being injured by Isaac, Julia LaForeze gets to him in time, but he is unable to do anything for the remainder of the battle. Meanwhile, Hector succeeds in stopping Isaac and sending Dracula's castle back into the abyss, effectively lifting the curse placed three years prior. So, despite his nearly fatal defeat, Trevor's mission was accomplished. In the game, he is unlocked after beating the game with Hector.
