Chapters 18-20 of The Giver

In Chapter 18, Jonas learns about the last person that was assigned the job of The Receiver. Her name was Rosemary and she had been in training for 5 weeks when she decided it was too much for her and she asked to be released. That was the failed attempt at a new receiver that happened 10 years ago. Jonas asks the Giver about release. He asks the Giver what would happen if he were to die. Where would all the memories go? The Giver tells him that the memories would be released into the community and that the community would suffer from all the pain. So, nothing could happen to either one of them; Jonas or the Giver.
Jonas tells the Giver that his father had to release a twin this morning and he wondered how it went. The Giver told him that if Jonas wanted to , they could get the videotape and watch his father doing the release ceremony. This surprises Jonas and scares him; at last he got to see what a release was like. They get the tape and watch as Jonas's father weighs both the twins. His secretary takes the heavier twin away and Jonas watches as his father injects a shot into the temple in the newchild's brain...
His father had just killed the child.
Jonas is overwhelmed with feelings. He can not believe that release means to be killed. The Giver tells him that he watched Rosemary's release. Or at least part of it. Rosemary asked to inject the shot herself, and the Giver didn't dare watch that part.
Jonas does not wan to go home to see his lying father so the Giver lets him spend the night with himself, in the Annex. They decided that the way their community is living, is no way to live. It is not right, not being able to feel anything or love each other. They make a plan.
Jonas was going to leave at midnight and get all the food remains that people left out. Jonas will go into the Annex. He will have left a note for his parents that he went out for a morning bicycle ride. Jonas will get in the trunk of a vehicle the next morning and he would be taken to Elsewhere. The community would soon discover that he is gone and they would grieve him. The Giver would stay behind to help everyone through all the pain. Jonas is upset by this because he doesn't want to live without the Giver; the one person he loves. The Giver tells him that he feels the same way for Jonas and that he had felt that way when he lost his daughter; Rosemary ten years ago. The Receiver had been his daughter! The one that couldn't take the pressure so she signed up for release was the Giver's child.
