Jonas and Gabriel are struggling in chapter 22. But, Jonas realizes that he has done the right thing, has made the right choice. He has made the final break from his community when he realizes something that is completely foreign to anyone in his community, or to him, up to this point. What signals the change in who Jonas is as a person

The change in who Jonas is as a person is signaled by the changing and irregular landscape that he witnesses for the first time.  For the first time in his life, he sees a bird, waterfalls, and wildflowers.  These objects were unknown to him in his former community.

At this point, Jonas realizes that Elsewhere could be nearby, and he makes the decision to continue on his journey to discovery.

Explanation:

Lois Lowry's 1993 novel titled "The Giver" chronicles the life of a 12-year old boy named Jonas.   The story is set in an utopian society where Jonas and Gabriel thought things were perfect.  They lived in this idealism until they discovered that their society was actually dystopian, heavily marked by corporate, bureaucratic, technological, moral, or totalitarian control.  "The Giver" teaches us that life is incomplete without some experiences of the beautiful, the ugly, and the not-too beautiful.
