At the end of The Giver, it is assumed that Jonas and little Gabriel reach safety in Elseware. When Jonas first left his community, search planes had frequently flown overhead. Jonas had to hide whenever he heard or saw one. Then that changed:
... the frequency of the planes diminished. They came less often, and flew, when they did come, less slowly, as if the search had become haphazard and no longer hopeful. Finally there was an entire day and night when they did not come at all (The Giver, Chapter 21).
Jonas began to have less fear of being caught. He felt confident that searchers were no longer trying to find he and Gabriel. Instead, he faced new challenges of hunger, thirst, and exhaustion. Jonas noticed the changes in the scenery. There were lush forests and refreshing streams. As Jonas travelled, he "felt that Elsewhere was not far away" (Chapter 23).
Jonas climbed to the top of a hill with Gabriel. When he reached the top, he could see a house with glowing lights. A memory came to him:
...he heard something he knew to be music. He heard people singing.
It is implied that Jonas and Gabriel rode the sled downhill until they reached the house with the singing people. This was obviously a place very unlike his community, because people were singing. It is also implied that it is a safe place.
