Marie-Laure LeBlanc—Etienne LeBlanc
All the Light We Cannot SeeMarie-Laure LeBlanc and Etienne LeBlanc’s great-uncle–niece relationship grows from a bond of quiet companionship into one of mutual trust and shared responsibility. Books and radios give them a common world, while fear, bereavement, and the dangers of occupation test what each can offer the other. Etienne’s promise to protect his niece does not remain a one-sided duty: Marie-Laure’s presence steadies him, and eventually he trusts her to undertake a task whose risks he names plainly.
Family, Reading, and a Shared World
Etienne is Marie-Laure’s great-uncle, and the intimacy between them is expressed less through grand declarations than through the small rituals of staying together. When he stops reading Darwin aloud because he senses someone nearby, Marie-Laure addresses him as her uncle and attends to his alarm. Later, when she sees him trembling in the cellar, she offers to sit with him and suggests that they continue their book. She does not treat his fear as a reason to abandon him; reading becomes a way to remain beside him through it.
Their companionship is sustained by Etienne’s books and radios. When Marie-Laure asks whether he misses the world, he taps Darwin’s cover and answers, “I have the whole world here,” adding that his radios put it within reach. The books and machines are not merely his private retreat: he shares them with his niece, inviting her into an intellectual world that accommodates both his seclusion and her curiosity. Her questions about the machine in the attic lead him to explain its construction, while listening together lets family history, science, and sound enter their daily life.
The radio also carries a family story that helps Marie-Laure understand the person behind the apparatus. Etienne tells her that his brother Henri had a remarkable singing voice and that the two brothers once planned to make recordings and children’s science programs. Etienne wrote scripts; Henri rehearsed them; Marie-Laure’s father, Daniel, came by as a boy to listen. Etienne recalls that work as one of the happiest periods of his life. By telling Marie-Laure about Henri, Daniel, and the broadcasts, he connects her to a family history that predates her own memories and makes the radio a shared inheritance rather than simply a machine in the attic.
Fear, Bereavement, and Care
Etienne’s withdrawal and fear shape the terms of their closeness. His recollection of the First World War explains why a sudden light could feel dangerous to him: as a signalman, he sometimes became so paralyzed that he could not move, even when flares illuminated the trenches. Marie-Laure recognizes that this experience lies beneath his terror. Her understanding does not erase his fear, but it gives her a way to respond to it with patience rather than reproach.
When Daniel is absent, Marie-Laure’s grief changes the atmosphere of the house. Its stairs, shuttered windows, and empty rooms frighten her; she refuses the food Madame Manec brings and shows little interest in the experiments Etienne attempts to perform for her. She is angry with him for doing too little and with Madame Manec for doing so much, while also grieving her father and blaming her own blindness. Her repeated exploration of the Saint-Malo model becomes a solitary way of tracing a home and a father she cannot reach. The scene reveals the strain on their household, but also the depth of Etienne’s commitment: he tries to cheer her even when his efforts cannot break through her grief.
That care becomes more explicit after Madame Manec’s death. Following four days in his room, Etienne comes downstairs and asks the women to leave, explaining that he needed time to say goodbye and must now look after himself and his niece. Once the kitchen is empty, he locks the bolts, takes Marie-Laure’s hands, and leads her toward the cellar. His grief has not passed; rather, he begins to take up the responsibility he has named. The gesture marks a change from a household in which Madame Manec often mediated their daily life to a more direct reliance between uncle and niece.
From Protection to Partnership
Their relationship is tested by the resistance work around them. Madame Manec argues that doing nothing is not an acceptable response and invokes both Etienne’s nephew and Marie-Laure when pressing him to act. Etienne is reluctant, but Marie-Laure is close enough to hear the confrontation. The exchange places her within the moral and practical pressures shaping her uncle’s choices: she is not only someone to protect but also one of the people whose safety and future give those choices weight.
When Etienne becomes anxious about the attic transmitter and its reach to England, the two work together to conceal the way into the attic. He finds an automobile jack, and they use it to raise the heavy wardrobe a little at a time, slipping folded rags beneath its feet before pushing it toward the small door. Marie-Laure helps move an object that is far too large for her to manage alone. The scene makes their cooperation physical and exact: Etienne devises the method, but the concealment depends on both of them doing the work. His fear is present in the care they take not to use a candle, while her participation shows how their relationship has widened beyond reading and comfort.
Trust and the Dangerous Task
After Madame Manec’s death, Etienne finally explains the responsibility that binds them. Coming down through the wardrobe’s back, he takes Marie-Laure’s hands and tells her, “Your father asked me to keep you safe.” She already knows what he is about to say. His protection of her is thus presented as both a promise to Daniel and a relationship Marie-Laure herself understands; she answers that she knows, without asking him to repeat or justify the obligation.
Etienne does not disguise the danger of what follows. He warns, “This will be dangerous. It is not a game.” Marie-Laure nevertheless says she wants to do it, invoking what Madame Manec would have wanted, and Etienne asks her to tell him the whole routine. Their exchange reverses the earlier pattern of adult care and child dependence without abolishing it: he remains responsible for her safety, but now relies on her knowledge and willingness. His final encouragement, “Then go, Marie-Laure. Go like the wind,” releases her into action rather than holding her in the shelter of the house.
The relationship’s decisive movement is therefore from protection as custody to protection joined with trust. Etienne cannot remove the danger around Marie-Laure, and his promise does not make him fearless. Instead, the two build their bond through shared attention—to a book, a radio, a family past, a hidden doorway—and finally through a task undertaken with full awareness of its risks. Their closeness is measured not by the disappearance of fear or grief, but by their capacity to remain beside one another and act.
