They visit these lairs and place sacramental bread in the boxes of earth to "sterilize" them, preventing Dracula from further using them. Dracula entices Renfield to invite him into Seward's residence. Renfield is found critically injured by Seward and Van Helsing who operate on him, and Renfield informs them that Dracula went to see Mina. They go to Mina's room and find Harker hypnotized while Dracula is giving Mina the 'Vampire's Baptism of Blood', cursing her and the group for plotting against him. The party use sacred items to repel Dracula, who flees into a different room as a vapour. Dracula then destroys all the texts Mina had produced, except for one which was hidden, and breaks Renfield's neck before leaving. Van Helsing places a wafer of sacramental bread upon Mina's forehead to bless her but it burns her flesh, leaving a scar. Mina, feeling that she is now connected with Dracula, asks Van Helsing to hypnotize her before dawn, the only time she feels she could freely speak. Through this hypnosis they learn that Mina has a telepathic link with Dracula, that she could tell everything he hears and feels, which could be used to track his movements. Mina agrees that any plans should be kept from her for fear that Dracula could read her thoughts. The group have additional encounters with Dracula as they continue to search for his residences throughout London and sterilize the boxes. Learning that his final grave is aboard a boat, Van Helsing deduces that Dracula is fleeing back to his castle. When the party pursues Dracula to Transylvania, they split into groups. While Mina and Van Helsing travel straight to Dracula's castle, the others attempt to ambush the boat on which Dracula is a passenger. Van Helsing's influence over Mina diminishes each day, and her behavior changes as she sleeps more during the day, loses her appetite for food, and ceases to write in her journal. He finds that she cannot cross a circle of crumbled sacramental bread. Later, Dracula's vampiric wives approach their camp but they too are unable to cross into the circle of bread. Failing at their attempts to lure Van Helsing and Mina out of the circle, they flee back to Dracula's castle just before sunrise. Van Helsing binds Mina at a cave to keep her from danger as he goes into Dracula's castle to kill the vampires.
