Jonas and Gabriel both have the Capacity to See Beyond.
Gabriel is the newchild that Jonas’s father brings home. In Jonas’s community, newchildren are usually raised by nurturers until the age of One. They remain in an institutionalized setting until assigned to family units. Jonas’s father is concerned about Gabriel, however. The newchild is clearly special. He brings him home for extra nurturing.
Lily is the one who notices, and points out, that Gabriel is different. The same thing that makes him different also makes Jonas different. They both have pale-colored eyes.
"Oh, look!" Lily squealed in delight. "Isn't he cute? Look how tiny he is! And he has funny eyes like yours, Jonas!" Jonas glared at her. He didn't like it that she had mentioned his eyes. (Ch. 3)
In Jonas’s community, everyone looks alike. The pale eyes set Jonas apart, so he does not like her drawing attention to them. However, the reference to the eyes foreshadows a deeper connection that Gabe and Jonas have. Both of them are related genetically to The Giver. Jonas and Gabe are actually real brothers.
Jonas feels a connection to the newchild right away. He is unsettled by the deep look Gabe seems to have because of those pale eyes. As Gabe continues to stay with them, he asks his father to put Gabe in his room. His fretting often keeps others away, but Jonas does not mind it.
When Gabe is in Jonas’s room, Jonas accidentally transmits a memory to him. Until this time, Jonas did not realize that he could transmit memories to others or that Gabe was special like him. It draws the two of them even closer together. When Jonas asks his parents if they love him and they respond by laughing, Jonas confides in Gabe that “there could be love.”
Gabriel's breathing was even and deep. Jonas liked having him there, though he felt guilty about the secret. Each night he gave memories to Gabriel: memories of boat rides and picnics in the sun; memories of soft rainfall against windowpanes; memories of dancing barefoot on a damp lawn. (Ch. 16)
Jonas loves Gabe like a brother, and he is horrified when he learns that Gabe is scheduled to be released. Even Jonas’s father voted to release him, this toddler that had been living in his house like a son for so long. Jonas decides that he needs to run, and run with Gabe. He takes the baby and leaves, knowing he can never come back. The escape is riskier with Gabe, but Jonas would never think of leaving him to his fate.
