Petyr–Deacon relationship

The Petyr–Deacon relationship is a deliberately comic version of vampiric kinship: Petyr is Deacon’s ancient sire, but the bond is presented less as solemn supernatural inheritance than as a family connection everyone enjoys recounting. Their relationship gives What We Do In The Shadows one of its clearest reversals of vampire convention, turning the origin of an undead monster into a cheerful family anecdote and making the household’s violence inseparable from ordinary domestic feeling.

Creation and Kinship

Deacon describes Petyr as the creature who attacked him, dragged him into a dark dungeon, bit his neck, and forced him to suck the attacker’s blood at the point of death. The account follows the familiar mechanics of vampiric transformation: bodily violence becomes an exchange of blood, and the dying human crosses into the condition of the Vampire. Yet Deacon narrates the memory with theatrical relish rather than solemn terror. His gestures dramatize the creature’s wings and shriek, while the revelation that Petyr is sitting beside him turns a scene of predation into the surprise appearance of a relative at a family reunion.

Petyr is the oldest vampire in the group and Deacon’s sire, giving him a position that combines generational authority with personal intimacy. The language of bloodline is therefore literal as well as social. Petyr is not merely the being who made Deacon immortal; he is the source of Deacon’s undead identity, the ancestor whose act of violence establishes the relationship on which the household’s later loyalties and resentments depend.

Affection, Rivalry, and Household Life

The relationship is defined by the contrast between its monstrous origin and its relaxed aftermath. Deacon presents the transformation as an entertaining story, and Petyr appears beside him as though the two are pleased to preserve the tale as shared family mythology. The comedy depends on the mismatch: an act that would ordinarily mark horror, death, and irreversible separation is absorbed into the routines of friendship. Petyr and Deacon are still friends, and that continued attachment matters more to the group than the brutality of the original encounter.

Deacon’s feelings become more complicated when Nick, the newest member of the vampire family, enters the household. Petyr turned Nick as well, and Deacon responds with jealousy. His behavior resembles that of an older brother forced to tolerate a younger sibling who suddenly claims the attention of the parents. The resulting conflict does not erase his bond with Petyr; instead, it exposes the possessiveness contained within it. Petyr’s role as creator makes him a shared source of belonging, but the same role also turns his attention into something that can be competed for.

This domestic pattern is central to the mockumentary’s treatment of the undead. The vampires argue, fret, and nurse wounded feelings as ordinary companions might, even though their social life is built around murder and immortality. Petyr and Deacon’s relationship makes that collision especially visible: the sire who once forced a human being into vampiric existence is also the elder whose approval and companionship can provoke the insecurity of a younger family member.

Petyr’s Death and Deacon’s Grief

The bond acquires its strongest emotional force when Petyr is killed by a vampire hunter. The hunter reaches the group after Nick accidentally alerts him to their presence in the city. Petyr’s death therefore results from the unstable expansion of the family: the new vampire’s arrival, already a source of jealousy, indirectly brings danger to the older household and leads to the loss of its oldest member.

Deacon is genuinely heartbroken when Petyr dies. His grief is shared by Viago and Vladislav, but Deacon’s position gives the loss a particular weight. Petyr is not simply a companion killed in a supernatural feud; he is the being who created Deacon and the elder around whom part of Deacon’s identity has been organized. The death removes both a friend and the origin point of his vampiric existence.

The aftermath also changes the comic meaning of their earlier reunion story. What first seemed like a punchline about an absurdly literal family bond becomes evidence of a relationship capable of loss. The joke does not cancel the grief. Instead, the film lets the two registers coexist: the memory of transformation remains ridiculous in its presentation, while Petyr’s death leaves Deacon and the others wounded in a recognizably human way.

Narrative Significance

Petyr and Deacon embody the mockumentary’s transformation of vampiric hierarchy into family comedy. Their bond retains the traditional structure of sire and progeny, but the narrative refuses to treat that structure as purely authoritarian or ceremonial. It appears through storytelling, teasing, jealousy, and companionship. The relationship is thus both supernatural and mundane: blood creates the connection, but shared anecdotes and emotional dependence sustain it.

Their story also complicates the usual division between monster and victim. Petyr’s creation of Deacon begins with coercion and near death, yet Deacon does not remain defined solely by that violence. He remembers the encounter, performs it for others, and continues to love the being who transformed him. The relationship carries harm, kinship, and loyalty at once, making the vampire family less a hierarchy of isolated predators than a damaged social world in which even immortals can behave like brothers, quarrel over attention, and mourn an elder when he is gone.
