The Giver is actually concerned about Jonas and the community. Since if Jonas drowns in the river, he will die, which will mean that the memories that Jonas has from The Giver will be released to the whole community and they will have to go through the same thing as the last time when Rosemary's memories were released to the community. The memories cause people in the community pain.
So he doesn't drown like a kid did years before.
The Giver plans to tell the community that Jonas drowned in the river, knowing that they will not question it since their memories of pain have been taken away. This would prevent anyone from searching for Jonas and uncovering the truth about the community.
Jonas runs away on pages 179-181 of "The Giver" by Lois Lowry.
Jonas gives people memories by running away so they can all go back to the community- for memories are forever. once he got memories, he has the ability to give them away to. he just followed what the giver did and gave some memories to Gabe.
Jonas flees the community after receiving memories from the Giver. He ventures into Elsewhere, leaving the community behind to seek a better life.
In "The Giver," the protagonist is Jonas, a young boy chosen to be the Receiver of Memories. The antagonist can be seen as the society in which Jonas lives, which strips away emotions and memories in the pursuit of sameness.
In the book, it explains that the Giver cannot escape with Jonas because he must help the community with their soon to be acquired new memories. Also, it implies that after the Giver helps the community he will apply for release and be with his daughter, Rosemary.
Jonas was sometimes sent away without training in "The Giver" when the Giver needed time to plan or reflect on how best to share memories or when the memories were too painful or difficult for Jonas to experience at that time. It also served as a way to build suspense and tension in the story.
The Giver sends Jonas away in order to protect him from the difficult and dangerous memories he carries. By providing Jonas with a place of safety, the Giver ensures that he can continue to receive the memories without being overwhelmed or harmed by them. This also allows Jonas to gain a new perspective on the world outside of the community.
The Giver transmits memories of wisdom, pain, joy, and adventure to help guide and prepare Jonas for his journey. These memories provide Jonas with knowledge and empathy to navigate the challenges he will face.
The Giver gave Jonas all of the memories, which contained experiences of the past world, emotions, and knowledge that had been taken away from the community. This enabled Jonas to understand the true depth of human experience and emotions.
Jonas was forced to leave the giver without saying goodbye because Gabe or Gabriel was going to be "released" in other words killed by the next day. Jonas had no choice but to escape with Gabe to save his life.
