Gabriel’s pale eyes could maybe mean that he is somehow related to Jonas. I predict that because in The Giver it is rare to have different coloured eyes then the rest of the people, or maybe Gabriel and Jonas have or come from the same birth mother. Also I think that they have strange abilities or powers because in the book when Jonas threw the apple to his friend he saw the apple change colours and he asked his friend if he saw the apple change colours, but the friend didn’t know what he was talking about and it got me thinking that maybe some people who have a different coloured eye have strange powers or abilities.
