Anton Gorodetsky and Kostya's friendship

Anton Gorodetsky's friendship with Kostya, the young vampire who lives in the apartment above him, is a central and deeply conflicted relationship in the novel, embodying the impossible ethical compromises demanded by the Treaty between Light and Darkness. It is a bond forged not in combat but in domestic proximity, sustained by mutual tolerance and a shared, unspoken understanding of the monstrous, and ultimately tested to its breaking point by the violence inherent in their respective roles.

Identity and Background

Kostya is only seventeen years old, a student at the physics faculty of Moscow University, and a vampire born to vampire parents. Anton discovered the truth about his neighbors five years earlier, when he first became an Other and could see the Twilight world. He was horrified to find that the family living directly above him—Kostya, his father Gennady, and his mother Polina—were not human beings at all, but registered vampires with brownish-gray auras and hideous pressure. Gennady, a contractor who had once helped Anton with concrete walls, opened his shirt to reveal the blue registration tag on his gray skin, proving they were all registered and had no known violations. Anton, a newly fledged adept of the Light, was stunned but ultimately accepted the situation, even inviting them for tea. The next day, he bought a cake, and Kostya began visiting him almost daily.

Life and Plot Trajectory

Kostya's visits became a regular feature of Anton's life. He would come to Anton's apartment, plunge into the Twilight, and boast about his new abilities—transforming, growing fangs. Anton would scold him gently, telling him he must never do certain things. The relationship was a strange, inverted mirror of a normal friendship: a Light Magician mentoring a young vampire, both pretending the fundamental horror of their situation could be managed by politeness and good intentions. This fragile equilibrium is shattered when Anton, on a mission to hunt a rogue vampire duo, kills the male vampire who had been initiating a girl. Kostya arrives at Anton's door to return borrowed CDs, his palms sweaty and eyes restless. He already knows one of his kind has died, because vampires sense it immediately. Anton explains he was doing his job, that the vampire was breaking the law and had killed innocent people. Kostya counters that the vampire should have had a trial, an attorney, a proper charge. The argument escalates: Kostya accuses Anton of being a human being for too long, and Anton roars that the law says human beings must not be involved in their business. Kostya then reveals he had been hoping Anton would become a vampire himself, that he could feel Anton's own hunger during the hunt. Anton refuses, and the conversation ends in a bitter stalemate.

Key Actions and Objectives

Anton's objective throughout the friendship is to maintain a human connection with Kostya, to prove that a Light One and a vampire can coexist without violence. He gives Kostya bottles of donor's blood, arguing that if someone needs blood to exist, the important thing is how they get hold of it, not whether it goes in through the veins or the stomach. Kostya, however, sees this as a bribe and a sign of Anton's true disgust. The relationship is a constant negotiation of boundaries: Anton tries to be a mentor and a friend, while Kostya tests the limits of that tolerance, pushing Anton to confront the hypocrisy of the Treaty. Kostya's own objective is to find a place in a world that has condemned him for what he is, and he looks to Anton—the only Light One who has ever let him into his home—for validation that he is not simply a monster.

Relationships and Conflict

The central conflict of the friendship is the irreconcilable difference between their natures and the roles assigned to them by the Watches. Anton is a Night Watch agent, sworn to police the Darkness; Kostya is a vampire, a creature of the Darkness. The Treaty allows licensed vampires to hunt and kill human beings, and Anton is forced to admit this truth to the boy Egor, revealing the terrible compromise at the heart of the Light's mission. This admission is a direct consequence of his relationship with Kostya: he has seen the system from the inside, and he knows that the line between legal and illegal is not a line between good and evil, but between order and chaos. The friendship is also a source of personal danger for Anton. During the hunt, Kostya and his family were lying in ambush for him, hoping the hunter would turn into the hunted beast. When Anton kills the rogue vampire, Kostya is devastated, and their argument on the roof of the building is a direct confrontation of their opposing worldviews. Kostya's final act in the novel is to appear on the roof to shield the captured girl-vampire from Anton's execution, forcing Anton to lower his pistol. He is not fighting for the vampire's innocence, but for the principle of a trial, for the very legalism he had demanded for his own kind.

Change and Ending

The friendship does not end in a dramatic break, but in a quiet, unresolved stalemate. After the confrontation on the roof, Anton and Kostya are left alone. Anton tells him he is not his enemy, not until Kostya crosses that line. Kostya, carrying the groaning girl-vampire, leaves with Semyon and Tiger Cub. The relationship is left in a state of suspended animation: they are still neighbors, still bound by the memory of shared tea and borrowed CDs, but the gulf between them has been made explicit. Anton has killed one of Kostya's kind, and Kostya has prevented Anton from killing another. They have each acted according to their nature, and the friendship, such as it was, can no longer pretend that their natures are compatible.

Narrative Role and Evaluation

The friendship with Kostya serves as a crucial moral counterpoint to the novel's larger conflicts. It prevents Anton from becoming a simple, unthinking soldier of the Light. By humanizing a vampire, the relationship forces Anton—and the reader—to confront the ethical cost of the Treaty. It is not an abstract philosophical problem; it is a seventeen-year-old boy who likes physics and borrows CDs. The relationship also functions as a warning: the Light's attempt to control the Darkness through registration and licensing does not eliminate the horror, it merely bureaucratizes it. Anton's friendship with Kostya is a testament to his own humanity, but it is also a source of his deepest moral anguish, because he knows that the system he serves would, under different circumstances, allow Kostya to be legitimate prey.
