Character Role Analysis
Van Helsing is brought in to advise Dr. Seward when Lucy is sick, and he sticks around to direct the Crew of Light until Dracula is dealt with. He knows how to kill vampires, and he also knows about a dozen languages, is familiar with the laws and customs of half the countries in the world, is a medical doctor and a chemist, and knows how to hypnotize people.
He's also a kind and wise old man. If we ever need a guide, we'd call Van Helsing.
