How is Dracula killed?
Jonathan slashes his throat while Quincey drives a knife into his heart as the sun sets; the body crumbles and Mina's scar disappears.
Why can Mina help track him?
Dracula's blood ritual links their minds, allowing Van Helsing to hypnotize her at dawn and sunset.
Does Mina become a vampire?
No. Dracula dies before the transformation completes, and the sacred-wafer scar leaves her forehead.
What is the cost?
Quincey Morris dies from a wound received in the final fight, and the Harkers later name their son after him.
Themes and What the Ending Means
Documents and collective knowledge: The archive converts isolated terrors into a solvable pattern.
Blood: Transfusion, inheritance, sexuality, contagion, and communion converge in the novel's central substance.
Modernity and the ancient: New technology helps defeat Dracula but does not make older knowledge obsolete.
Consent and invasion: The vampire repeatedly crosses bodily, domestic, and national boundaries.
Friendship: The hunters' willingness to believe and act for one another is their strongest defense.
