Bobbi Anderson and Anne Anderson’s sisterly relationship
The TommyknockersBobbi Anderson and Anne Anderson’s sisterly relationship begins as a pattern of estrangement and attempted control, then becomes one of the novel’s starkest reversals. Anne arrives in Bangor expecting to bring her younger sister home after their father’s death; in Haven, she confronts a Bobbi altered by the force working through the town and discovers that the sister she once expected to command now controls the terms of their reunion.
Background and Estrangement
Anne is forty when she arrives in Bangor after a delayed, uncomfortable flight. The narration presents her as blunt, irritable, and accustomed to asserting herself. Bobbi, by contrast, is absent from the journey and initially absent from the family’s crisis: after their father suffers a stroke and his death becomes imminent, Anne tries to reach her twice, but Bobbi does not answer. When Anne calls again after the death, a drunk answers the phone. The repeated failure to make contact turns Bobbi’s silence into the immediate source of Anne’s grievance.
Anne interprets that silence as a refusal to face family obligations. She believes Bobbi should have attended their father’s funeral and resents that their mother suffered when Bobbi did not come home. Her account is not neutral: Anne expects her wishes to prevail, and she treats Bobbi’s return as something she can arrange rather than a choice her sister must make. That expectation gives their estrangement a coercive edge before they meet again.
The Funeral and Anne’s Plan
At first, Anne is certain Bobbi will attend the funeral because Anne intends her to be there. She has also told a lie that she expects Bobbi to deny if confronted. Anne anticipates that other family members may remember the accusation even if they do not settle whether it is true. The episode shows her managing the family’s perceptions as well as trying to secure Bobbi’s presence; reconciliation is entangled with pressure and the threat of public embarrassment.
Getting Bobbi to the funeral is not enough for Anne. She decides that Bobbi must come home permanently and thinks of this as overdue. Her confidence that she can make it happen carries the relationship’s central imbalance into the present: Anne frames reunion as a demand, while Bobbi has so far answered her efforts with silence. The novel later makes that silence especially consequential by setting Anne’s certainty against Bobbi’s transformation.
Reunion in Haven
When Anne tells Bobbi that their father is dead, Bobbi replies that Newt Berringer has already informed her. Anne says they buried him without Bobbi and that their mother had been deeply affected by her absence. Bobbi does not defend herself. Anne also tells her that their mother fell downstairs four days earlier and broke her hip; Bobbi responds with indifference. These exchanges give Anne further evidence of the distance she fears, but they do not restore her authority over her sister.
Anne tells Bobbi that she is coming home with her and tries to make the statement sound forceful. Instead, her voice betrays weakness. Bobbi answers with a teasing question about whether Anne really wants her to come out where Anne can see her. Anne urges her to stop playing with her, then Bobbi invokes the years in which Anne had treated her—and the rest of the family—in the same way. The reply reframes Anne’s present demand: the sister who claims the right to summon Bobbi is confronted with a history in which Bobbi felt subjected to Anne’s control.
Transformation and Reversal
When Bobbi steps into view, the sisters’ conflict is altered by the physical change in Bobbi. After showering, she appears profoundly nonhuman: her head and neck are transparent, her body is changed, and unfamiliar organs and green fluid are visible beneath the surface. Anne sees the transformation rather than the sister she expected to confront. Bobbi’s altered body makes the gap between their assumptions and their present reality impossible to ignore.
Bobbi welcomes Anne to Haven and says she had not expected her, but believes they can find a job for her because positions remain open. The language of homecoming has become language of recruitment. Anne had meant to take Bobbi back to the family; Bobbi instead treats Anne’s arrival as an opportunity to assign her a place within the transformed town. The sisters’ encounter ends with Bobbi in control and Anne terrified, a decisive reversal of Anne’s earlier certainty that she could determine what Bobbi would do.
Aftermath and Significance
Later, Gard recognizes the woman Bobbi had called Sissy as a fiend whose hatred persists even in agony. Anne is subsequently seen in a tank, where her eyes burn with hatred and fury. Together, these scenes confirm that the reunion has not brought the sisters back into ordinary family life: Anne has become part of the transformed circumstances Bobbi introduced her to, and their relationship is now marked by fear, hostility, and the consequences of Bobbi’s alien-influenced condition.
The relationship’s arc turns on the meaning of home. For Anne, home means the family and obligations to which she believes Bobbi must return. For Bobbi, once transformed, Haven becomes the place into which she can welcome and assign her sister. The final reversal does not erase the earlier estrangement; it makes its unresolved grievances part of a more frightening separation, in which the sisters remain bound to one another but no longer meet as equals within a recognizable family world.
