Héctor discovers the mangled corpse of journalist Ricardo Montoya in the lagoon. After recovering from the initial shock, the boys realize that they have lost the only evidence they had of the death of the five orphans. When they return to the well to try to find more evidence, they see that workers are permanently sealing the entrance. They are told that these are orders from the school administration. From that moment on, accidents begin to occur in La Laguna Negra, and the boys realize that the danger they have been warned about is real. Jacinta is depressed. As always, the postman brings back the letters she sends to her daughter Verónica.
