Returning to the Valerious family's castle, Carl explains that Dracula is, in fact, the son of Anna's ancestor, imprisoned within an icy fortress, hidden behind a large walled map of Transylvania. Using the torn parchment, Van Helsing opens the portal, finding Dracula's fortress. The captured monster informs Van Helsing that Dracula possesses a cure for lycanthropy; Carl realizes that only a werewolf can kill Dracula. Capturing Igor, Van Helsing sends him, Anna, and Carl to retrieve the cure, while he frees the monster. As he does so, the monster is struck by lighting twice, bringing Dracula's children to life. Dracula, spotting Van Helsing, transforms into a demonic form, fighting Van Helsing in werewolf form. Aleera and Igor are both killed as Anna and Carl retrieve the cure. Following a fierce skirmish, Dracula then reveals to Van Helsing that it was he who murdered him 450 years earlier. Dracula offers to restore all of Van Helsing's memories, but he declines, stating that some things are better left forgotten. Eventually, Van Helsing kills him and his children by biting Dracula's throat, but accidentally kills Anna as she delivers the cure.
