I think that Gabriel’s pale eyes mean something like that the nurtures made a mistake for example they forgot to to give some kind of chemical, maybe Jonas and Gabriel are related because there the only two people that have “pale eyes” also I predict that maybe Jonas and Gabriel’s can only see the apple change for example maybe they can see more than normal people I honestly think that Gabriel is going to be a big factor in the Giver I also think that Gabriel and Jonas are some way related.
