Parents are assigned babies and Jonas's dad got a baby "illegally". The bays name is Gabriel and he has trouble sleeping so Jonas transmits smoothing memories to Gabriel so he can sleep. He does this every night. When he learns that whenever someone is released, it means the same as death. Jonas and Gabriel form a big bond.
I will help you escape
The Giver tells Jonas about the girl who had been designated the new Receiver ten years before. She had been the Giver’s own daughter, but the sadness of some of the memories had been too much for her and she had asked to be released. When she died, all of the memories she had accumulated were released into the community, and the community members could not handle the sudden influx of emotion and sensation. Jonas and the Giver plan so Jonas can escape the community and go to Elsewhere(Beyond the community). Once Jonas leaves and enters elsewhere, his memories will disperse and the Giver will help the community cope with the new thoughts and feelings, changing the community.
