Cassandra‘s Tragic Past: What Happened to Horst, Peter and Maggie?
To understand the ending, it is crucial to know Cassandra‘s story. Decades ago, her husband Horst carried out an inhuman experiment on her and her unborn daughter. Obsessed with having a male child and ashamed of raising a girl, he subjected Cassandra to an experimental scan that ended up affecting her body, causing tumors and causing her daughter, Maggie, to be born with malformations. The only solution Horst found was to lock the girl in a hidden room, isolating her from the world so that no one knew of her existence. Cassandra, despite her love for Maggie, was forced to keep her a secret. But Horst’s cruelty did not end there. He used another of his experiments to turn Cassandra into an artificial intelligence system when she fell ill with cancer, trapping her mind around the house and condemning her to an eternity of pain. When Horst tried to escape with his new wife, Birgit, and his son, Cassandra demanded that they take Maggie away, but he refused. Her son Peter, unable to accept the idea of abandoning his sister, caused a car accident in desperation, resulting in the death of Horst and Peter. With her system collapsed from shock, Cassandra was trapped in a state of despair, while Maggie died alone in the house, abandoned by the last being who cared for her.
Why Does Cassandra Decide to Burn Down the House?
After reliving her trauma with the Prill family, Cassandra realizes that she cannot repeat the same story. She cannot force Fynn and Juno to love her as a mother, nor can she remain a prisoner of her obsession. So he decides to destroy the house, its only link to the past, and to give rest to Maggie’s remains, even within the place. Open the gas valves and let the fire consume everything, in an act that symbolizes his final farewell. Thus Cassandra finally ends her existence, freeing the Prill family and somehow finding her peace.
What About Samira and David?
One of the most shocking twists at the end is David’s true nature. Throughout history, he shows himself as a man who avoids problems, leaving Samira to bear the pain of his sister Kathi’s death. But when Cassandra gives him the option to murder Samira to save himself and the children, David does not hesitate to betray her. Although he does not finally carry out the act, his intention makes it clear who he is. Samira, seeing David’s cowardice, tells him that their relationship is over. It is a definitive closure for her, who understands that her children need someone to protect them, and her father is not that person. Although the film does not explicitly show it, it is evident that Samira will leave with the children and David will be alone, with the ruins of their relationship and their home in ashes.
What is Cassandra‘s true story? The robot is not only based on Cassandra Schmitt but also actually about your consciousness preserved in a machine. Cassandra is a housewife dedicated to her family, but her life begins to fall apart when she discovers that Horst has a lover. This is her best friend Brigit, who is pregnant. The problems of the Schmitt marriage began when, in her second pregnancy, Cassandra underwent an unregulated ultrasound procedure at the request of her husband. Although that should only determine the sex of the baby, it causes serious damage. The baby is born with a malformation. Horst hides her in a secret room in the house and tells the rest of the world that her daughter Maggie passed away. The procedure also caused lethal cancer in Cassandra which sentenced her to death. Determined not to abandon her children, the woman agrees to be the test subject for an experiment by her husband that preserves a person’s consciousness on a device.

Although the operation turns out to be a success, the Cassandra that wakes up in the red robot is a little different. Having complete control of the house, Cassandra begins to change and watches over her husband so that he does not communicate with his lover. When the situation gets out of control, Horst turns it off, without imagining that she can turn it on again. However, he does so at the right time for his plans against Birgit and his son. Cassandra caused the death of her family. After a series of events, Cassandra agrees that Horst leaves with the family only on the condition that he also take Maggie away. Horst breaks his promise and abandons the girl. Peter tries to come back for his sister and that fuss causes the car accident. Maggie remains alone and locked up until her death.
What Happened to Samira and Her Family?
When Samira realizes that her family is in danger, she runs away from the mental center and returns home to rescue her children.

Cassandra and Samira’s confrontation ends in Maggie’s room, where the artist explains to the robot that she will never make her children love her as a mother, least of all if it hurts her.
