Analysis & Themes
John rushes into the Park Lane Hospital for the Dying, where Linda is staying. The nurse matter-of-factly says there's no hope of recovery. When John says Linda is his mother, the nurse blushes.
Linda is so drugged on soma she barely notices John. As John weeps, the nurse leads a group of Bokanovsky twins into the room. They stare at Linda and make nasty comments about her ugliness. John, furious, pushes them away. The Nurse warns him not to interrupt the children's death-conditioning.
John returns to Linda, who thinks he's Popé. It's too much for John: he shakes his mother, who stops breathing, and dies. John blames himself, falls to his knees and begins to sob. To stop this display of sadness from harming the children's conditioning, the Nurse gives all the kids chocolate éclairs.
