Tommy’s mother and Staffan’s relationship
Let the Right One InTommy’s mother and Staffan’s relationship is presented as a developing family arrangement rather than as a romance experienced only between the two adults. Their affection becomes visible in everyday domestic scenes, then takes the form of a marriage announcement and a possible move to an expensive house in Ängby. Tommy’s responses place the relationship under a second kind of scrutiny: he has to absorb what it may mean for his household while his mother insists that Staffan is a good person. The plans are clear, but the scenes do not establish that the marriage or move has yet taken place.
From Private Affection to an Open Plan
The relationship is already intimate before the couple explains it to Tommy. When he enters the hallway, he hears his mother and Staffan kiss behind him; their subsequent exchange is private and incomplete from his perspective. The moment establishes that their closeness is not merely a future possibility, even as Tommy remains outside the conversation between them. His mother’s later question about why he says things about Staffan suggests that she notices and resents the way he tests the relationship with pointed remarks.
At dinner, the closeness becomes part of a shared domestic scene. Staffan accompanies Tommy’s mother on the piano while they sing, looking at one another and smiling. Tommy, by contrast, sits apart on the leather sofa and picks at a hole in its armrest. The contrast is not simply between a happy couple and a resentful child: the scene is filtered through Tommy’s unease as he tries to understand the adult relationship around him. His attention turns to ordinary objects and settings—the sofa, the piano, the picture of the Virgin Mary, and the pistol safe under the bed—as he wonders what place he occupies in this changed household.
After the song, Tommy’s mother and Staffan sit together at the piano bench, with the image of the Virgin Mary above them. She turns to Tommy and says that they have something to share. He immediately asks if they are getting married. His guess precedes their disclosure, indicating that the prospect is already legible to him, but his mother hesitates: the direct question was not part of what they had prepared to say. Staffan confirms the marriage plan and asks what Tommy thinks. Tommy shrugs and tells them to go ahead. His brief answer gives the announcement no overt objection, but his earlier discomfort prevents it from reading as unqualified enthusiasm.
Tommy’s Misgivings and His Mother’s Defense
Tommy’s reservations surface through questions about what the proposed future will require. When the possibility of a house in Ängby comes up, he points out that it is expensive and asks whether Staffan has enough money. His mother asks whether he likes it; Tommy answers that he loves it. That answer separates his response to the house from his concern about affordability. The exchange shows him engaging with the practical implications of the plan rather than simply refusing it, but it does not resolve how the house will be paid for or whether they will move there.
His mother’s defense of Staffan is more direct. After Tommy makes a sarcastic reference to Staffan’s pistol-shooting prizes and the Virgin Mary, she says, “He’s a good person, Tommy.” Tommy replies with another pointed remark, treating Staffan’s shooting awards and religious image as an incongruous combination. The exchange captures a difference in how they assess him: his mother offers a straightforward judgment of character, while Tommy notices the objects and signs that make Staffan difficult for him to read. The evidence does not show his mother withdrawing her defense or Tommy abandoning his doubts.
The dinner setting also places Staffan’s possessions within the family’s emerging domestic life. He shows Tommy the safe where he keeps his pistols, stored under the bed. For Tommy, this detail becomes part of the larger effort to imagine the adults’ private life and the new arrangement taking shape around him. The scene gives no account of Staffan’s reasons for keeping the pistols, so their significance here remains tied to Tommy’s attention and to his uncertainty about the man who is to become his stepfather.
A Household Plan Interrupted
The couple’s announcement is followed by a practical glimpse of a shared future: the house in Ängby is described as expensive, and Tommy’s mother sits beside him while Staffan answers. Before the discussion can continue, the telephone rings. Staffan strokes her cheek and leaves the room to answer it. This small shift from intimate conversation to an outside call changes the scene’s direction without settling the family’s questions.
Staffan returns with news that the killer is at the Vällingby swimming pool and that the police station lacks enough people. He goes to the bedroom, opens the safe, changes, and emerges in police uniform. He kisses Tommy’s mother, touches Tommy’s knee, and says he must leave at once and does not know when he will return; the couple’s further discussion will have to wait. Tommy’s mother follows him into the hall, where Tommy hears her tell him to be careful and say that she loves him. Their relationship is thus shown both in domestic tenderness and in the abrupt demands of Staffan’s police work.
The interruption leaves the marriage and housing plans unresolved within these scenes. Staffan’s departure does not cancel the announcement, but it prevents the family from working through its practical consequences together. For Tommy, the prospect of a changed household is therefore introduced in fragments: a kiss overheard, a mother’s defense, a formal proposal, a house whose cost he questions, and a police call that carries Staffan away. The relationship matters to the plot not only because the adults intend to marry, but because Tommy must interpret that intention while the adults’ shared future remains both concrete and unfinished.
